CalcWhale, right inside Telegram
Every tool on this site, without opening a browser. Unit conversion, QR codes, word solvers, calendar files, and send a photo to pull its dominant colors — all as chat commands. Free, no account, nothing stored.
Commands
/convert
value + from-unit + to-unit → the result. Same 486 pairs as the site converters.
/qr
Any text or URL → a 512px QR PNG, sent straight back as an image.
/words
Unscramble letters (up to two ? wildcards) against the 172k-word ENABLE list.
/pattern
Positional match like a??le — crossword and Wordle-style solving.
/ics
Title and date → a downloadable calendar file that opens in any calendar app.
Send a photo
No command needed — just send an image and get its dominant colors back as hex codes.
FAQ
Do I need to install anything?
No — if you have Telegram, you have the bot. Search @calcwhalebot or open t.me/calcwhalebot and tap Start.
Is it free?
Yes, entirely. No account, no premium tier, no payment ever asked for.
What happens to what I send it?
Nothing is stored. Each message is processed by the same public API behind calcwhale.com and forgotten — a photo you send for color extraction is downloaded, analyzed, and discarded, not kept.
Can I add it to a group?
Yes — it only responds to commands, @mentions, or replies to its own messages in groups (Telegram's default privacy mode), so it won't interject in normal conversation.
I need this in my own app, not a chat.
Every command is a public API — the same one the bot calls. See the developer options below.
Building your own integration?
Every command above is a public API — the bot is just a thin Telegram front-end for it. Convert, QR, word-solving and calendar generation are all live on RapidAPI, with a free tier on each. Full docs: api.calcwhale.com/api.
