What you can ask César

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.

• “I spent 84 dollars at the grocery store today, on debit.” Try it in the chat →
• “How much did I spend on delivery this month?” Try it in the chat →

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

• “When am I free on Thursday afternoon?” Try it in the chat →
• “Move tomorrow's meeting to next week, same time.” Try it in the chat →

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.

• “Call the clinic and cancel my Thursday appointment.” Try it in the chat →

• “Call the store and ask if the product has arrived.” Try it in the chat →

César summarizes what arrived, flags what needs a reply and leaves the draft ready — you just approve before it goes out.

• “Summarize the emails that arrived today.” Try it in the chat →
• “Reply to the realtor's email saying I accept the offer.” Try it in the chat →
• “Find the email with the fridge invoice.” Try it in the chat →

Requires Gmail, Outlook or Zoho Mail connected.

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

• “Add 'renew my driver's license' to my list, due end of the month.” Try it in the chat →
• “What is still pending this week?” Try it in the chat →
• “Mark buying the gift as done.” Try it in the chat →

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.

• “Remind me to take my medicine at 10pm.” Try it in the chat →
• “Every Monday morning, send me a summary of tech news.” Try it in the chat →
• “Warn me three days before my bills are due.” Try it in the chat →

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.

• “Build me a 10-day trip to Portugal in October, out of Boston, around 6 thousand for two.” Try it in the chat →

• “Has this car ever been in an auction or an accident?” Try it in the chat →

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. A wellness estimate, not a medical exam.

• “Measure my heart rate.” Try it in the chat →
• “How has my heart been this week?” Try it in the chat →

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

• “Watch this sneaker's price and tell me if it goes under 100.” Try it in the chat →

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

• “What's the best sushi place near me open now?” Try it in the chat →
• “How do I get downtown from here?” Try it in the chat →
• “What do the reviews say about this hotel?” Try it in the chat →

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

• “Is it going to rain tonight?” Try it in the chat →
• “What's the weather in London right now?” Try it in the chat →
• “Do I need a coat to go out at 7pm?” Try it in the chat →

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

• “Look up whether this supplement actually works.” Try it in the chat →
• “Read this page and tell me what matters: https://…” Try it in the chat →
• “Find a video on replacing a faucet cartridge and summarize what it says.” Try it in the chat →

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

• “Summarize today's news about artificial intelligence.” Try it in the chat →
• “What came out this week about interest rates?” Try it in the chat →
• “Did anything relevant happen with Apple today?” Try it in the chat →

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

• “What did we agree about the December trip?” Try it in the chat →
• “Find the conversation where we discussed the renovation budget.” Try it in the chat →
• “What was the restaurant you recommended last week?” Try it in the chat →

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 Dashboard → Activity.

• “What happened in my account this week?” Try it in the chat →
• “When did I disconnect Google?” Try it in the chat →
• “What did you do for me yesterday?” Try it in the chat →
• “Show me this month's travel activity.” Try it in the chat →

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.

• “Copy the contract from Drive to my computer.” Try it in the chat →
• “Send that holiday video from my PC to Dropbox.” Try it in the chat →
• “Save the invoice from OneDrive here in the chat.” Try it in the chat →
• “Where is the budget file?” Try it in the chat →

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

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.

• “Draw a birthday invitation with a dinosaur theme.” Try it in the chat →
• “Remove the background of this photo.” Try it in the chat →
• “Trim this video from 0:30 to 1:10.” Try it in the chat →
• “Make this video square for Instagram.” Try it in the chat →

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.

• “Chart my expenses by category over the last 3 months.” Try it in the chat →
• “Show my cholesterol trend as a line.” Try it in the chat →
• “Put August's expenses in a pie.” Try it in the chat →
• “Compare sales by store from this spreadsheet.” Try it in the chat →
• “How much did I spend this month? Show it as a headline figure.” Try it in the chat →
• “Switch that chart to bars.” Try it in the chat →

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.

• “What is 12% of 3,450?” Try it in the chat →
• “Add these up for me: 120.50, 89.90, 45, 230 and 12.75.” Try it in the chat →
• “How much is 1,500 at 1.2% a month over 12 months?” Try it in the chat →
• “Of my August expenses, how much was restaurants and what share of the total?” Try it in the chat →
• “What is my average of workouts per week?” Try it in the chat →

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.

• “Join clientes.xlsx with pedidos.csv and tell me who bought in both.” Try it in the chat →
• “Extract every table from this PDF into a single spreadsheet.” Try it in the chat →
• “Build a scatter chart with a trend line from this CSV.” Try it in the chat →
• “Simulate 10,000 scenarios of this portfolio with 8% mean return and 15% deviation.” Try it in the chat →

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.

• “Make a spreadsheet of my August expenses: groceries 450, power 180, internet 120.” Try it in the chat →
• “Make an 8-slide presentation about the quarter's results.” Try it in the chat →
• “Merge these three PDFs into one.” Try it in the chat →
• “Convert this spreadsheet to PDF.” Try it in the chat →
• “Summarize this contract I sent.” Try it in the chat →
• “What do the expenses in this spreadsheet I sent add up to?” Try it in the chat →
• “Export my August expenses to a spreadsheet.” Try it in the chat →

Public Instagram, TikTok and X profiles by @handle, post comments and videos by pasted link, fake-account signals — and posting on X, Instagram and TikTok from your account.

• “Look at the @handle profile on Instagram for me.” Try it in the chat →
• “What did @nasa post on X this week?” Try it in the chat →
• “Does this profile that messaged me look fake?” Try it in the chat →

• “Post this video on TikTok, public, with the title: behind the scenes at César. [attach the video]” Try it in the chat →

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

• “Note that the garage gate code is 4712.” Try it in the chat →
• “What was the wine I liked at the birthday dinner?” Try it in the chat →
• “Remember that Ana is allergic to shrimp.” Try it in the chat →

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

• “Save the plumber's contact: Jorge, 555 888-7766.” Try it in the chat →
• “Tag Ana as my girlfriend.” Try it in the chat →
• “Tell my mom I arrive at 8pm.” Try it in the chat →
• “Create a 'renovation' group with Jorge and the architect.” Try it in the chat →

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

• “Find the lease agreement in my Drive.” Try it in the chat →
• “Share the cost spreadsheet with Pedro.” Try it in the chat →
• “What does the penalty clause in that contract say?” Try it in the chat →

Requires Google Drive, OneDrive or Dropbox connected.

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

• “Tell João I'll be about 20 minutes late.” Try it in the chat →
• “Ask the pizza place if they deliver to my neighborhood.” Try it in the chat →
• “Send my reminders through Telegram.” Try it in the chat →

Requires WhatsApp or Telegram connected.

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. The final click (paying, placing the order, cancelling) is always yours: he stops there and hands you the live browser.

• “Go to Amazon, find the Cosco Toffy car seat and put it in the cart.” Try it in the chat →
• “Go to the city's site and download my property tax slip.” Try it in the chat →
• “Fill in my registration on this site with my details.” Try it in the chat →
• “How is the browser task going?” Try it in the chat →

Logins, captchas and SMS codes you handle in the live browser, and César carries on from there. Billed by model usage and browser minutes.

Say where you're going and César gets the ride ready in Uber or 99 — destination filled in, you just confirm in the app.

• “Take me to the airport.” Try it in the chat →
• “Get me an Uber to my mom's house.” Try it in the chat →
• “I need to be at the doctor's at 3pm, when should I leave?” Try it in the chat →

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.

• “Connect my computer.” Try it in the chat →
• “Which of my computers are online?” Try it in the chat →
• “List the files on my desktop.” Try it in the chat →
• “Take a screenshot of my screen.” Try it in the chat →
• “Open the accounting app on my PC and download the August report.” Try it in the chat →
• “How is the task on my computer going?” Try it in the chat →

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.

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.

• “Review this lease and tell me what is unusual before I sign.” Try it in the chat →
• “Help me write a delicate e-mail turning down an offer.” Try it in the chat →
• “Build a 4-week study plan for my certification exam.” Try it in the chat →
• “Organize my week: these are the 12 things I need to deliver.” Try it in the chat →
• “Review my business finances and tell me where I am stretched.” Try it in the chat →

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.

• “Build an app to track my rental units.” Try it in the chat →
• “Add a button that generates the quote PDF and sends it to the client on WhatsApp.” Try it in the chat →
• “When an order becomes shipped, lock the record and leave only a Reopen button.” Try it in the chat →
• “Flag overdue rentals in red and give me a quick filter for them.” Try it in the chat →
• “Make a client screen with their details, the total spent and their rentals in a tab.” Try it in the chat →
• “I want the list on the left and the selected record's details on the right.” Try it in the chat →
• “Warn me when an order goes 3 days without a reply.” Try it in the chat →

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.

• “Make a page for my bakery with orders over WhatsApp.” Try it in the chat →
• “Publish our wedding page with the gift list and the map.” Try it in the chat →
• “Add a quote form that lands in my clients app.” Try it in the chat →
• “I want to take sign-ups — create the app along with the page.” Try it in the chat →
• “Show me three design variations of this page.” Try it in the chat →
• “How many people visited my page this week, and where did they come from?” Try it in the chat →
• “Change the page colour to green and put the cake photo at the top.” Try it in the chat →

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

• “From now on, always answer me short and to the point.” Try it in the chat →
• “Don't send me alerts before 9am or after 10pm.” Try it in the chat →
• “What do you remember about how I like things?” Try it in the chat →
• “Forget that preference about meeting times.” Try it in the chat →

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

• “Connect my Google account.” Try it in the chat →
• “Is my Outlook connected?” Try it in the chat →
• “Sync my e-mail now.” Try it in the chat →
• “Disconnect TikTok.” Try it in the chat →

Stuck on something? Open a ticket without leaving the conversation, follow the answer and reply from here.

• “I can't connect WhatsApp, open a support ticket.” Try it in the chat →
• “Has support replied yet?” Try it in the chat →
• “Reply on the ticket that it works now.” Try it in the chat →

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

• “How many credits do I have left?” Try it in the chat →
• “What credit packages are there?” Try it in the chat →
• “I want to buy more credits.” Try it in the chat →
