Telescope follows public Telegram channels and chats for you. When one of your words appears in a new post, it sends you a signal: the word is underlined, and you see the channel, the author and a link to the original post.
Set it up once and get on with your day. Typical jobs: keyword alerts for Telegram channels, tracking mentions of a brand, following a topic, catching a listing or a request before others do.

footballmatchesfootballer) - Number -> exact match (
2026won't match20261) - Phrase -> full phrase match (
rent apartment) - Combination -> all words at once, in any order (
looking + apartmentneeds both) - A comma finds any of the words (
football, hockey), a plus finds all of them
- Single word -> prefix match (
-
🚫 Exclude keywords - put
-or!before a word (-football) to skip posts that contain it, even if another keyword matched -
📡 Multiple input formats - add channels by
@username,t.me/link, or web Telegram URL

Is there a bot that notifies me when a keyword appears in a Telegram channel? Yes - Telescope does exactly this. Add a channel, add a keyword, and you get an alert when a new post matches.
How do I track mentions of my brand or product on Telegram? Add the channels you care about and your brand name as a keyword - Telescope keeps checking new posts and sends you an alert when one matches.
What's included in the free tier? Up to 2 channels and 50 keywords per user, alerts usually within a few minutes. Pro is available as a free demo on request in the bot: up to 5 channels, unlimited keywords, regular expressions, faster delivery and a personal web cabinet with feed, statistics and export. Paid plans, including integrations with your own apps (Slack, Notion, your own service), will come later.
Can I monitor a Telegram channel without joining it? Yes - Telescope only needs the channel to be public; you don't have to join or be a member.
Can I monitor private channels or groups? No - only public channels, the kind anyone can read without an invite. This is the same restriction every Telegram bot has.
Can I require several words in the same post?
Yes - join them with +: looking + apartment matches only when both words are in the post, in any order. Words separated by a comma work the other way: any one of them is enough. A combination counts as one keyword in your limit.
Can I exclude certain words from matching? Yes - add exclude keywords to filter out matches you don't want, without having to drop the main keyword entirely.
How fast are alerts? On the Free plan alerts usually arrive within a few minutes of a post going live. On Pro they usually arrive within seconds. The time is not guaranteed and can be longer.
Are keywords case-sensitive? No. Matching ignores case and works across English, Russian, and other Unicode scripts.
Do you store the posts?
Not as an archive. Post text is checked against your keywords. Short alert previews are kept for a limited time so your feed works, then deleted. You can remove everything at any time with /deletedata.
How do I delete my data?
Send /deletedata in the bot - everything tied to your account is removed immediately.
Does this work for apartment listings, job postings, or niche marketplace channels? Yes - any use case where you want an alert on a keyword in a public channel works: real estate, jobs, deals, brand mentions, news topics, and more.
