TELEGRAM BUSINESS · OBSERVER
See what they unsent.
Sight Bot is a silent observer for Telegram Business. It never replies on your behalf — it just makes sure no counterparty message ever quietly disappears.

PRIVACY · THREE MODES
The privacy ladder is the hero feature, not the tier table.
01 · DEFAULT
Mirror Mode (DM)
Counterparty messages mirrored to this DM with <1s delay. Only 48-hour integer ID pairs on our servers.
02 · PRO PRO ⭐
Mirror Mode (your channel)
The mirror lands in your private Telegram channel. Your messages bypass our database entirely.
03 · ARCHIVE
Standard (file_id only)
Text encrypted with AES-256-GCM, master key on the operator. Media stored only as Telegram file_id (also encrypted).
SETUP · THREE STEPS
No website signup. None.
STEP 01
Connect the bot
Telegram → Settings → Telegram Business → Chatbots → @sight_service_bot
STEP 02
Open the DM
Send /start. You'll get the welcome and onboarding card.
STEP 03
Pick a mode
/storage_mode → Mirror Mode, Standard, or Personal channel (Pro).
WHAT'S INSIDE
Six properties. Nothing dressed up.
Real-time alerts
Deletions and edits land in your DM in under a second. Pro lifts that to a ≤2s priority queue.
No auto-reply, ever
The bot never speaks on your behalf. No LLM helper.
AES-256-GCM
In Standard mode every text and caption is encrypted at rest.
Master key on you
We literally cannot read your content without your operator key.

QUESTIONS
What people ask first.
Does it auto-reply?
No, never. Sight Bot is a silent observer. It mirrors counterparty messages and flags deletes/edits — that's it.
Can it track group chats?
No. The Telegram Business API only delivers updates from private one-to-one chats.
Can I export history?
Yes, on Pro — CSV and JSON exports. Free does not include export.
What about big files?
Media over 20 MB isn't downloaded — a known Bot API limit. We surface the filename, size, and caption; the content stays in Telegram.
