Lemma Telepath

Lemma Telepath connects your Telegram Business account to ChatGPT so your assistant can work with your own business conversations. Ask it to summarise a thread, find the message where a price or a deadline was agreed, read a screenshot a client sent, listen to a voice message as text, or draft and send a reply as you.

It is built on the official Telegram Business API: you add our bot as your Business chatbot in Telegram and grant it the rights you choose, so there is no MTProto user session and nothing is scraped. From that moment your 1:1 business messages are archived into an account that is yours alone — one isolated database per account, full-text searchable, including the text inside attachments and transcripts of voice and round-video messages.

You stay in control of what the assistant may do. Every capability — replies, media, notes, group archiving — is a switch you can turn off at any time from the bot, and sending is surfaced for your confirmation before anything reaches another person. You can erase everything you have stored with a single command.

Telepath is not end-to-end encrypted and we say so plainly: searching and transcribing require our servers to read your messages. Data is encrypted at rest with full-disk encryption, each account is physically isolated, and voice transcription is opt-in, disclosing the processor it uses before you turn it on. If you need a guarantee that no operator can ever read your data, the same connector can be self-hosted on your own machine.
