## Add it to your group (zero setup)
Add the official bot β no install, no config, no cost.
### β [@iLangGuardBot](https://t.me/iLangGuardBot)
1. Search `@iLangGuardBot` on Telegram
2. Add it to your group
3. Give it admin β **delete messages** + **ban users**
4. Done. Spam is cleaned automatically; @ it anytime with a question.
You can also DM it directly for AI chat.

## What it does
**π« Anti-Spam** β Catches ads, scams, crypto & gambling spam. Sees through Unicode lookalikes, full-width and zero-width tricks, emoji stuffing and slang. A zero-cost pre-filter kills the obvious stuff before it ever reaches the AI, and repeat-flooding is caught with no AI call at all.
**ποΈ Vision** β Reads images and video thumbnails to catch image-based ads and QR-code scams. In chat, it reads the story behind a photo, not just the pixels.
**π¬ Chat** β @ it in any group or DM it privately. Multilingual, auto-detects your language. Ask it anything and get a clear, useful answer β factual on sensitive topics, with sensible boundaries on genuinely harmful ones.
---
## Self-Host
Bring any **OpenAI-compatible** AI provider β [SiliconFlow](https://cloud.siliconflow.cn) (default), OpenAI, DeepSeek, or a local model. You need two things:
- **Bot Token** β [@BotFather](https://t.me/BotFather) β `/newbot`
- **AI API Key** β from your provider (default targets SiliconFlow)
### Option 1 β VPS (one command)
```bash
curl -sL https://raw.githubusercontent.com/ilang-ai/TelegramGuard/main/install.sh | sudo bash
```
Clones, installs dependencies, prompts for your two keys, and runs as a systemd service. Manage it with:
```bash
systemctl status telegramguard # status
systemctl restart telegramguard # restart
journalctl -u telegramguard -f # live logs
```
### Option 2 β HuggingFace Space (free, no server)
1. Fork this repo
2. Create a [HuggingFace Space](https://huggingface.co/new-space) β Docker SDK β Blank
3. GitHub repo β Settings β Secrets β add `HF_TOKEN` (your HF write token)
4. HF Space β Settings β Secrets β add `BOT_TOKEN` + `AI_API_KEY`
5. HF Space β Settings β enable **persistent storage** so `/data` (the SQLite DB) is writable β or add a `DB_PATH` secret pointing somewhere writable
6. Push to GitHub β it auto-deploys to the Space
### Option 3 β Manual
```bash
git clone https://github.com/ilang-ai/TelegramGuard.git
cd TelegramGuard
pip install -r requirements.txt
cp .env.example .env # fill in BOT_TOKEN + AI_API_KEY
set -a; source .env; set +a # load .env into the environment
python bot.py
```
After creating your bot, send to [@BotFather](https://t.me/BotFather): `/setjoingroups β Enable` and `/setprivacy β Disable` (so it can see group messages).
### Configuration
Everything is set via environment variables β see [`.env.example`](.env.example):
| Variable | Default | Purpose |
|----------|---------|---------|
| `BOT_TOKEN` | *(required)* | Telegram bot token |
| `AI_API_KEY` | *(required)* | OpenAI-compatible API key |
| `AI_BASE_URL` | `https://api.siliconflow.cn/v1` | Provider endpoint |

| `AI_VISION_MODELS` | `Qwen/Qwen3-VL-30Bβ¦` | Vision fallback chain (comma-separated) |
| `AI_AUDIO_MODEL` | `Qwen/Qwen3-Omni-30B-A3B-Instruct` | Voice-message model |
| `AI_IMAGE_MAX_WIDTH` | `600` | Downscale width before vision calls |
| `AI_FALLBACK_API_KEY` | *(empty)* | Optional second provider; set to enable a cross-vendor fallback |
| `AI_FALLBACK_BASE_URL` | *(empty)* | Endpoint of that backup provider |
| `AI_FALLBACK_MODEL` | *(empty)* | Text/judge model there |
| `LEXICON_HARD_THRESHOLD` | `6` | Slang pre-filter strictness (higher = stricter) |
| `PROBE_FLAG_DELETE` | `2` | Check-in filler flags before it starts deleting (never bans) |
| `PROBE_WINDOW_HOURS` | `24` | Rolling window for those flags |
| `JUDGE_TEXT_LIMIT` | `1800` | Chars of a long message the judge sees (head + tail) |

## Customize the AI
The bot's brain lives in plain `.ilang` files β [I-Lang Prompt Spec](https://ilang.ai), where each `::GENE` defines a behavior.
```
prompts_demo/
βββ persona.ilang how it thinks + how it talks
βββ antispam.ilang what counts as spam
βββ vision.ilang how it reads images
```
```
::GENE_IMMUTABLE{S002, T:RUTHLESS_RED_TEAM, A:FLATTERβFAIL, G:ALL, Ξ:ALWAYS}
# Show it a plan and it hunts the fatal flaw instead of praising.
::GENE_MUTABLE{P002, T:CONCISE, G:ALL, Ξ:ALWAYS}
# 2-3 sentences. Answer first, detail after, zero filler.
::IMMUNE{SPAM, DETECT_THEN_NUKE}
# Ads / scams / flooding β delete + strike, see through evasion.
```
Change the genes, change the bot. To customize: copy `prompts_demo/` to `prompts/` (loaded first) and edit.
