Are the Telegram and Viber bots free?
Yes. The bots run on the same shortener as the web form. No signup, no paywall, no ad. Each chat user gets their own list of short links and per-link click stats.
What commands do the bots understand?
Six commands. /start and /help return an onboarding message. /shorten <url> creates a short link; a bare URL pasted into chat is treated the same way. /mylinks lists your recent links. /stats <code> returns per-link click count, last-click time, and last-7-day and last-30-day breakdowns. /delete <code> deletes one of your links.
Do the bots track my chat or share data?
No. The bots store only your platform user id, the links you have asked them to shorten, and aggregate click counts. No third-party trackers, no chat history, no contact list, no message scraping. Links you create are owned by your bot identity, so you can list and delete them yourself.
Does the bot send a QR code back?
Yes. Every shorten reply attaches the QR code for the new short link as an image, so you can save and share it without leaving chat. The web result page additionally exposes an SVG download and a colour and size customiser.
Is the bot rate limit different from the web form?
Yes. Bot submissions use a separate budget of 20 short links per minute, keyed on your chat platform user id rather than your IP address. The web form and the JSON API have their own independent budgets, so the three lanes cannot drain each other.
