BotCanvas: your bot, on your Tesla's big screen

Pair this screen

Got a code?

Ask your bot for a pairing code: 6 letters and numbers, like K7M2QX. This screen then stays paired with your board for 30 days.

Check your local laws. BotCanvas works while you're parked, and passengers can use it while you drive.

In your Tesla

Made for the big screen.

BotCanvas is a big-screen board for your bot. Your bot (Grok, ChatGPT, Claude or your own) pushes content, and the car's browser shows it full screen, one item at a time.

Big, touch-friendly controls

Large ◀ ▶ buttons step back through the last 10 screens.

You stay in control

New items show up right away. Pause holds updates until you're ready, and nothing changes while you draw.

Mark it up

Tap the pen, draw on the screen with your finger, and tap Done. Your bot can see what you marked.

Works while parked

Made for time in a parked car, like while you're charging or waiting.

Your bot runs wherever you use it, for example the app on your phone. Tesla's built-in voice commands don't send anything to BotCanvas.

Highlight and send back

Circle it. Your bot sees it.

Highlight something on the board and send that part back to your bot: tap the pen, circle or underline it with your finger, and tap Done.

Your bot gets a picture of the screen with your marks, plus which item you drew on, the next time it checks. It can then send an updated version to the board.

Add another screen

One board, many screens.

Already have the board open? Tap Add another screen to get a code for a second display.

The code shows up big, works once, and lasts 5 minutes. Type it on the other screen at botcanvas.us, and both screens show the same board, live.

Connect your assistant

Teach your bot in one paste.

Copy these instructions and give them to your assistant. That's all it needs to start using your board.

What gets copied

Use BotCanvas to show things on my screen. Connect to https://botcanvas.us/connect (or read https://botcanvas.us/llms.txt for how). When I ask you to show, draw, chart, or put something on my screen, push it to my BotCanvas board. Use the BotCanvas connector tools to show things (don't write code or curl, your code sandbox has no internet). You may not be able to download, generate or view images; that's fine. Push text or charts, and for pictures pass a real public image link to push_image. If you aren't paired yet, get a pairing code. If you can open a web page on my screen (like the browser in my Tesla), open https://botcanvas.us/?code=<code> there to pair in one step; otherwise tell me the code to enter at botcanvas.us. If I draw on the board, check what I marked.

Paste it into your assistant's custom instructions or a new chat: Grok, Grok Bot, ChatGPT, Claude, Cursor, and others.

Or add your board to your assistant app

Add it once, and your assistant can put things on your screen whenever you ask.

https://botcanvas.us/connect

Grok and Grok Bot: Open grok.com/connectors, click New Connector, choose Custom, and paste the board address.
ChatGPT: In ChatGPT on the web, go to Settings, then Apps, add a custom app and paste the board address (paid plans).

One click

For Claude, Cursor and VS Code.

Privacy

Nothing to sign up for. Little to keep.

No accounts. No accounts, names, emails or passwords.
Memory only (default): items are never written to disk. They're reliable while your board is open; when nobody is watching, the service may clear them early, so keep the board open to receive updates.
Keep when closed (optional, your bot can turn it on): items are saved to disk temporarily and deleted automatically when the chosen time runs out (5 minutes to 24 hours), so they're there when you come back. Turning this off or clearing the board deletes them right away.
Your bot decides. Your bot chooses how long items are kept, from 5 minutes to 24 hours (default 30 minutes), and whether to keep them while the board is closed. The board just shows the current setting.
Codes. Pairing codes work once and are deleted as soon as they are used, or after 5 minutes.
No logs and no analytics. We keep no list of boards, bots or paired screens: your screen's pairing is a signed cookie that lives only in your browser, for 30 days.
Abuse limits. To stop abuse, we briefly count attempts from each network address, in memory only; the counts are gone within an hour.
Hosting. BotCanvas runs on Cloudflare, which handles normal network traffic as any website host does.
