What you can ask César

Everyday

What he keeps and remembers for you: appointments, tasks, notes and whatever you have already told him. 7

Calendar

One sentence becomes an appointment, with reminders and guests. César also finds free slots and reorganizes your week.

Tasks

Lists, deadlines and subtasks without opening another app: you say it, César writes it down and follows up on time.

Reminders and scheduled tasks

From a simple reminder to a repeating routine: César watches deadlines, prices and news and comes tell you — in the app, on WhatsApp or on Telegram.

Notes

'Note that…' saves it; asking brings it back. The gate code, the client's preference, the wine you liked.

Memory

Tell him once and he does not forget: your price list, your opening hours, your accountant's name, what to answer when someone asks for a quote. César consults what you saved before acting — and you read, fix and delete any note whenever you want.

Contacts

Save a person, find a phone number, organize groups — and tag relationships: with a tag, "tell my girlfriend" needs no name.

History

César remembers your conversations: ask about what was already agreed and he brings it back, without you repeating everything.

Money

Where the money went, what is due, what renews — and your payment details kept in a vault. 3

Money

Tell him what you spent — by text, voice or a photo of the receipt — and ask where the money went. César records, categorizes and answers.

Subscriptions

Everything that bills you every month in one place: César adds up the total, warns you before each renewal and, on approved services, cancels or restarts it for you — no support queue, no hunting for the hidden button.

The list is fixed, with the services César knows how to operate — Netflix, Spotify, Globoplay, HBO Max, Paramount+, Amazon Prime and MUBI — and each starts disconnected until you connect it. Cancelling or restarting goes through a confirmation sheet, and he signs in with the code the service e-mails you, never with your password.

Cards and documents

Save them once and César fills them in for you: your ID, driver's license and passport go into sign-ups and purchases without retyping, and your card sits in a vault, encrypted while still on your device — used only at the checkout of a purchase you authorized.

Cards are added only on the Cards screen: the number never goes through the conversation.

Shopping and delivery

He finds the product, compares prices across stores, places the order and follows it to your door. 5

Shopping lists

Say what you need and César builds the list, finds each product, compares the price of the whole basket across stores and places the order for you — groceries, pharmacy, pet shop and home. At the end he hands you the Pix code to pay and keeps the receipt, with delivery time and shipping.

Purchases happen at approved stores — close to a hundred today, across groceries, pharmacy, pet shop, drinks, home, electronics, fashion and sports: Pão de Açúcar, Supernosso, Atacadão, Verdemar, Apoio Entrega, Pague Menos, Drogaria Araujo, Petz, Cobasi, Zé Delivery, Americanas, Leroy Merlin, Tok&Stok, Decathlon, Netshoes and Riachuelo, among others. Some deliver only in certain cities; César checks your address before placing the order.

Food delivery

Hunger is an order, not a search. Say what you feel like eating and César finds who delivers to your address, builds the order the way you like it and hands you the Pix — you just pay and wait.

Today delivery runs on iFood, using your saved address. César builds the order and shows everything — items, fee and ETA — before any charge: paying is always yours to do, with the Pix he hands back.

Prices and wishlist

Compare a product's price across stores — and leave César watching until it drops.

Second-hand

Find anything for sale between people — a phone, a bike, a couch — with price, condition and distance. And from the other side of the counter: César publishes your ad on OLX and Mercado Livre, reads who got in touch and answers for you.

Today on OLX classifieds, Mercado Livre and Enjoei, with your account connected right in the conversation (you get a code). Posting, taking down and answering whoever got in touch he does on OLX and Mercado Livre. The search is live, and the deal with the buyer or seller is yours: César neither pays nor receives in your place.

Parcels

César finds the tracking code in your email on his own, follows the carrier and alerts you when it is out for delivery.

Talking to people

Calling, writing, replying and letting people know — by phone, on WhatsApp, by e-mail or on social. 7

Phone calls

César places real phone calls on your behalf — cancel an appointment, confirm a reservation, ask for information. You review the plan, approve, and the outcome comes back to chat with a summary and transcript. When negotiating times, he checks your calendar and only accepts free slots.

Your own phone number

A Brazilian number of your own, run by César: the calls and WhatsApp messages he makes on your behalf go out from that number, and the reply comes back to your chat. He gets and activates it by himself — you never type a code.

Has a monthly fee charged in credits, and the supply of available numbers is limited.

WhatsApp and Telegram

Talk to César on WhatsApp like any other contact — and get alerts and reminders on Telegram, without opening the app.

Requires WhatsApp or Telegram connected.

Your own WhatsApp

Connect YOUR OWN account and stop scrolling for what matters: César reads what you missed, says what each person wants and answers in your name when you tell him to — groups included. Sending a message always goes through your confirmation, with the text on screen.

Requires your WhatsApp connected: say “connect my WhatsApp” and type the 8-digit code on your phone.

Email

César summarizes what arrived, flags what needs a reply and leaves the draft ready — you just approve before it goes out. And he alerts you when something important arrives, instead of alerting you about everything.

Requires Gmail, Outlook or Zoho Mail connected — or CesarMail activated.

CesarMail

An email address of your own ([email protected]), run by César. Forward tickets, bills and reservations, or use it for site sign-ups: a ticket becomes a calendar event, a bill becomes a payment due, a tracking code becomes a parcel — and you read, reply and send from the chat.

Starts switched off: you activate it whenever you want, and the address is yours forever.

Home, health and car

The life that happens off-screen: your body, the doctor, the car, where you live and how you get there. 7

Health

Point the front camera at your face for 30 seconds and César estimates heart rate and breathing right there, without the video leaving your device — then compares it with your usual. With Strava connected he sees your workouts, and can build a weekly training plan and track what got done. Tell him your weight and what you ate and he tracks the trend and your energy expenditure. A wellness estimate, not a medical exam.

Doctor appointments

Book without calling: César finds a professional with an open calendar, shows the price, the insurance accepted and the address, and books in your name. With no good slot, he keeps watch and tells you when one opens.

Today booking runs on Doctoralia, with your own account on the site (confirmed by a code on your phone). Nothing is charged here: the appointment is paid at the office. Symptoms, tests and results are Health; an appointment you already have belongs to the Calendar.

Vehicles

Register your car and César watches IPVA, licensing and federal-highway fines: he tells you what is left to pay, with the slip ready as Pix or barcode.

Real estate

House hunting takes weeks, and César shortens it: he indexes the listings in your city, filters by neighborhood, price, bedrooms and parking, and follows the search to tell you what showed up, what dropped in price and what came off the market.

These are public listings from the portals (VivaReal, QuintoAndar and Chaves na Mão): César shows, compares and follows. Visiting, negotiating and signing remain yours and the agency's.

Rides

Connect your Uber account right here — tell me the phone number, send me the code — and I will quote and request the ride for you. Without a connected account, I get the ride ready in the app with the destination filled in.

Places and routes

A well-rated restaurant near you, the way there and what the reviews actually say — not just the stars.

Weather

The weather where you are joins the conversation on its own; for another city or the rest of the day, just ask.

Travel and going out

From the ticket to the gig: he puts the trip together, shows the total price and books in your name. 5

Travel

César builds the whole trip from very little — and you change it by talking. Airfare, lodging, car, activities and flight status, with real prices, the transfer between one place and the next, and the link for you to buy.

Plane tickets

Ask for the ticket by route and date, by flight number, or send the airline's search link. César shows the flights and fares, builds the purchase in your name and tells you beforehand how it is paid: Pix at GOL and Azul, a saved credit card at LATAM.

The ticket is issued in your name, with your profile data (birth date, sex, mobile) and the CPF from your documents, and it is the airline that issues the e-ticket after payment. Today César buys at GOL, on domestic flights, for the account holder only.

Bus tickets

Ask for the trip by departure city, arrival city and date. César shows the bus companies, times and prices, lets you choose the seat and closes the purchase by Pix after your yes.

The ticket is issued in your name, with your profile data (birth date and mobile) and the CPF from your documents, after payment. The seller charges a service fee, which the sheet shows before your yes. Today César buys at ClickBus, for the account holder only.

Stays

Say the destination, the dates and how many people: César finds where to stay, shows the total price with fees — not the headline nightly rate — and books in your name.

Today booking closes on Booking.com, on the pay-at-the-property rate — no card charged at the time. On Airbnb César searches, quotes and lays out the sheet, and the final confirmation is still yours.

Event tickets

Send an event link — a gig, a party or a movie session — and César shows the tickets and prices, builds the order in your name and hands you the Pix to pay. A free event becomes a registration, with no payment.

The ticket is issued in your name and it is the ticket office that sends it, to your e-mail, after payment. Today César buys at Sympla, ingresso.com and Cinemark, from the event's or session's link.

Work and making things

What he produces: documents, spreadsheets, charts, images, apps and research with sources. 14

Spreadsheets, documents, slides and PDF

Ask for a spreadsheet, a document or a slide deck with whatever you need inside, convert files, merge or split PDF pages, or ask what a contract says — the file comes back in the chat with a download button.

Charts from your data

Ask for a chart of expenses, lab results, workouts or a spreadsheet you sent — it appears in the conversation, with the table, alt text and a PNG to share.

Exact math

Ask for any calculation — a percentage, the sum of a list, an instalment, an average, interest — and the number comes back computed on the server, with the steps to check it. Also works over expenses, orders and spreadsheets César has already read.

A program over your data

When a calculation or a fixed recipe is not enough, César writes a Python or JavaScript program, runs it in an isolated box and returns the result and the generated files. Works over spreadsheets, PDFs, CSVs and over what other modules already read.

Video and photo

Ask for a brand-new image or send a photo and say what to change; with videos, trim, convert, resize, extract the audio, make a GIF. The result comes back in the conversation.

Apps

Describe what you want to track — clients, rentals, orders — and César builds a custom app: screens, dashboards and automations. You can put it all on one screen: a client's details with their numbers beside them and their records in tabs. The app's buttons use the rest of César — generate PDFs, send WhatsApp and email, post to your finances — always asking for confirmation first. Once published, it shows in the Dashboard menu and answers in chat like any module.

Web pages

Say what you do and César writes and publishes your page at pages.usecesar.com — text, photos, colours and a form, all by talking, with the preview beside you. If the form needs somewhere to land, he creates the app alongside it (after asking). It can take orders, show your app's catalogue, switch between ready-made styles and tell you how many people visited.

Skills

César puts on the right expert by himself: send a contract and legal mode steps in; ask for a hard text and writing takes over. The pill in the conversation shows the active mode — and in your profile you can switch any of them off.

Missions

Long work with a deliverable, done while you sleep: César plans, produces, critiques his own result with a second model and redoes it until it is good — and delivers in the chat at the time you asked.

Job openings

Ask for the role, the place and the work mode and César brings the open postings — company, city, remote or on-site and the link to apply. Follow a search and he tells you when a new posting opens.

Applying always happens on the posting's own site: César shows and notifies, he does not apply for you.

Move files between places

Say from where and to where. César finds the file by the name you use — in Drive, Dropbox, OneDrive, your computer or here in the chat — and takes it to the other side. The original is never deleted.

Works with the places you have already connected: Google Drive, Dropbox, OneDrive and your computer. For the chat and media files, nothing needs connecting.

Cloud files

César finds, reads and shares files in your Drive, OneDrive or Dropbox — and answers questions about their content.

Requires Google Drive, OneDrive or Dropbox connected.

Web search

Anything that changed after yesterday, César searches the web on the spot — reads pages, finds videos and answers citing sources.

News

Recent headlines on any topic, with outlet, publication time and link — dated, not a timeless roundup.

He acts for you

When there is no shortcut: he opens the real site, uses your computer and faces the paperwork. 5

Browser

When the site has no shortcut, César opens a real browser and uses the site by looking at the screen, like a person — searching, filtering, filling in and building the cart in the background. If you ask him to buy, he completes the purchase all the way; otherwise he stops at the final click and hands you the live browser. Cancelling, deleting and transferring are always yours.

With CesarMail activated, César creates the account on the site, fills in your details and reads the confirmation code by himself. He only calls you into the live browser when the site demands biometrics, a captcha or a confirmation on your phone — and carries on from there. Billed by model usage and browser minutes.

Your computer

You install an agent on your PC, connect it with a code, and César looks at your files, runs commands and can even use the screen with mouse and keyboard to finish a task — read-only by default, with every change passing through your approval.

Requires the César agent (version 1.5 or newer to control the screen) installed and connected to your account. Controlling the screen needs write access on and is billed by model usage; moving the mouse or keyboard pauses it right away.

Lawsuits

Give a name, CPF, CNPJ or lawsuit number and César looks up how many lawsuits there are, in which courts, about what and who the parties are.

This is public data from courts and official gazettes. Given the lawsuit number César goes to the court's own page and brings the parties, the movements and the claim value when the court publishes them; by name or tax id what comes back is the list, where homonyms show up — and finding nothing does not mean the person has no lawsuit.

Public records

Before paying a supplier or filing an invoice, just ask: César looks up the company register at the tax authority and reads the invoice by its access key, live, on the official portals.

This is public data: the tax authority's company register and the national NF-e and NFS-e portals — an invoice is only readable by whoever holds the access key, and the lookup takes a few seconds because the portal demands a captcha. Issuing YOUR OWN invoices is Invoices, in the company space.

Reclame Aqui

Tell what happened with a company and César builds the complaint from your facts, publishes it from your Reclame Aqui account and tells you when the company answers.

The complaint is public and goes out in your name: César only writes what you told him and shows the exact text before publishing. The final evaluation (solved or not) is done by you on the site.

Your account

What to connect, how he talks to you, how much you have spent and where to ask for help. 5

Connected accounts

Connect, check and disconnect your accounts from the conversation. Passwords and keys never go through the chat: César sends a secure link.

Your way

Say it once and César keeps it: the tone, what to call you, what to avoid — and the hours he may send you alerts.

Credits and plan

Balance, packages, top-up and plan subscription without leaving the conversation — and César warns you on his own when the balance runs low.

Activity

Everything that happens in your account is recorded: what you did and what César did for you. Ask in the chat or open the list in your account menu → Activity.

Support

CESAR FOR COMPANIES

For your company

A separate space, with your team: the attendant on the company WhatsApp, orders and charges, what left the account, spreadsheets and contracts answering in plain language, and the record of who did what.

These examples work inside the company space. Meet César for companies

Serving and getting paid

The attendant on the company WhatsApp, the orders coming in, the charges and what landed in the account. 5

Customer service

César's attendant answers customers on the company's WhatsApp. You follow along, adjust the tone and take over the conversation whenever you want.

Requires the company's WhatsApp connected under Customer service.

Orders and charges

Build the order with items, send the payment link (Pix, card or boleto), charge on the spot, refund and follow payment (and why it failed) — from the chat, the attendant or the Orders screen.

Requires one of the company's payment platforms connected under Integrations: Pagar.me, Mercado Pago, Asaas, Stripe, Iugu, Vindi, PagBank, Efí, PicPay or the WooCommerce store.

Payments

What left the company account — transfers, Pix sent, purchases and subscriptions — with the platform of each. Read-only: César moves nothing here.

Requires a company account that reports outgoing money, connected under Integrations: Mercado Pago, Asaas, Stripe, Iugu or Efí.

Treasury

The company account inside César: open it from the chat, add money by Pix, pay bills by boleto or Pix copy-and-paste, see balance and statement and withdraw to the company's own account — every outflow confirmed with a code sent to the owner's e-mail.

Payment account operated by Asaas. Only the owner submits the application, pays bills and withdraws.

Invoices

Issue NFS-e through the national standard straight from the chat, follow each invoice until it is authorized and cancel when needed — always with your confirmation first.

Requires the issuer set up under Invoices, with an A1 certificate, a series and a tax profile.

Data and systems

The company's spreadsheets and contracts answering in plain language, your own APIs and the public page. 3

Data sources

Upload the sales spreadsheet, the contract, the handbook — and ask in plain language. The answer comes with the math shown or the page cited, never unsupported.

Requires a spreadsheet or document connected under Data sources.

Tools

Connect the ERP, the CRM or any company API — via MCP, OpenAPI or by typing the endpoints — and César queries and drives those systems from the chat, asking before changing anything.

Requires a server connected under Tools, with its tools turned on.

Company pages

The company's public page built by talking: menu, app catalogue, a contact form that becomes a record, and the WhatsApp attendant embedded. Members draft it; admins publish.

Publishing, archiving and deleting are for company admins.

Team and the record

Who is in, with which role — and the record of who did what. 2

Team

Build the company team from the conversation: invite, adjust roles, remove who left and see how much each person used this month.

Who did what

Everything that changes in the company is recorded with who did it: connections, charges, refunds, deliveries, team. Ask instead of digging.

Just send the message

None of this needs setup: message César on WhatsApp, say what you need and he tells you when connecting an integration is worth it.
