Problem

Same thing every day.
While you sleep, your chat gets overrun.

01 · Bots

Crypto scams, casinos, "easy income"

Dozens of identical messages per hour. Links to fake exchanges, schemes, Pump & Dump.

73% of new members · bots
02 · Scammers

Fake admins,
phishing, impersonation

DMs "from the admin", fake airdrop links. Members lose money and trust.

€2.8B stolen · Telegram 2025
03 · Toxicity

Insults,
hate speech, spamming

Active members leave. Manual moderation does not scale. The community slowly dies.

Customization

Full control
over AI.

No coding required. Manage complex logic via the Telegram Mini App. Toggle modules on and off with one click.

Voice, Photo & Video
Gemini Vision reads text on images on the fly, while audio is transcribed to analyze for spam and scams.
Night Mode
Set stricter ban and deletion thresholds for nighttime. The bot guards the chat while you sleep.
AI Appeals Killer Feature
A banned user can submit an appeal. AI analyzes the context and can lift the ban automatically.
Anti-Raid & Shared Blocklist
During a massive bot attack, the chat enters Lockdown mode. Spammers from your other chats are banned preemptively via a Shared Blocklist.
Fine-grained thresholds
You decide how many violations (Points) trigger a Mute or Ban, and set when warnings expire.
Installation
