Start the bot

Open the configured Telegram link.
Press Start or send /start.
Send /help to view supported bot commands.

Commands in the bot implementation

/start — create/find the Telegram-linked account and show a welcome message.
/help — list current commands and calculator examples.
/language bn — save one of eight locale preferences; inline calculator replies use it immediately.
/profile and /premium — show account and payment availability.
/note add key text, /note search words, /note delete key — private encrypted notes. Use only in a private bot chat.
/remind ISO-time+offset title (or prefix with daily/weekly) — Plus reminders.
/todo add text, /todo, /todo done id — Plus to-do list.
/reply set trigger text, /reply list, /reply trigger — Plus quick replies.

Reminder times require an explicit ISO-8601 UTC offset. Recurring reminders repeat at a fixed duration and do not adjust for daylight-saving changes. Plan checkout is disabled, so Plus is not currently purchasable.

Inline calculator

Enable inline mode for the actual bot in BotFather, run the bot worker, then type an expression after its Telegram username in any supported chat.

1+1 → 2(1+1)-5*5 → -230.1+0.2 → 0.32^10 → 1024sqrt(144) → 1215% of 200 → 30

Calculation precision is 128 significant Decimal digits with ROUND_HALF_UP. Inline display rounds non-integers to 12 significant digits; integer results stay exact. Exponents are limited to −100 through 100, expressions to 256 characters and 128 tokens, with at most 16 nested groups/calls.

Troubleshooting

If no launch link appears, configure TELEGRAM_BOT_URL or TELEGRAM_BOT_USERNAME.
If Telegram says the bot cannot be found, confirm the configured username in BotFather.
If inline queries do not return results, enable inline mode and confirm the bot worker is running.
If an expression is rejected, check syntax, supported functions, and the expression limits.
