A browser extension that filters AI-generated content from your social feeds. Runs entirely in your browser. Bring your own API key. No account, no backend, no telemetry.
Unslop classifies posts in your LinkedIn, X, and Reddit feeds using an LLM of your choice. The model returns a direct keep or hide decision for each post. Everything runs locally in the Chrome service worker; only the LLM API calls you configure ever leave your machine.

Setup
Open the extension popup and enter:
| Field | Example |
|---|---|
| API Key | your key from OpenAI, OpenRouter, etc. |
| Base URL | https://api.openai.com/v1 |
| Model | claude-haiku-4-5 |
Save, flip the toggle, scroll your feed. Done.
Supported platforms
| Platform | Status |
|---|---|
| ✅ | |
| X / Twitter | experimental |
| experimental |
Supported providers
Any OpenAI-compatible endpoint works:
| Provider | Base URL |
|---|---|
| OpenAI | https://api.openai.com/v1 |
| OpenRouter | https://openrouter.ai/api/v1 |
| Ollama (local) | http://localhost:11434/v1 |
| vLLM / LiteLLM | your own URL |
Recommended model: claude-haiku-4-5 — fast, cheap, accurate for classification. Any model with JSON mode works.
How it works
Each post is classified directly in the Chrome service worker:
post arrives in feed
↓
local classifier (your API key)
↓
keep / hide

Post text is sent only to the API endpoint you configure. No analytics, no telemetry, no external requests beyond your own LLM calls. Your API key lives in chrome.storage.local.
