Page Assist is an open-source (MIT) browser extension that adds a sidebar and full web UI for interacting with AI models from any webpage, including web-page-aware chat and document/RAG-style retrieval. It targets local models first (Ollama, LM Studio, llama.cpp, Llamafile, vLLM, Chrome AI/Gemini Nano) but also supports any OpenAI-compatible endpoint. Users add providers via Settings to an "OpenAI Compatible API" tab, choosing from a large dropdown (OpenAI, Anthropic/Claude, Google AI, Groq, Mistral, DeepSeek, OpenRouter, Together, Fireworks, xAI, Hugging Face, and many more) or "Custom" to enter an arbitrary API URL plus their own API key. All data is stored locally in browser storage with no telemetry. Available on Chrome, Brave, Edge, Firefox, Vivaldi, Opera, Arc and other Chromium/Firefox browsers.

Why this trust score (68/100)

Trust measures how the tool treats your API key and how much of that has been verified. It contains no popularity signal.

  • Key Safety 13/25: The key is persisted in browser local storage, which any script on the page can read.
  • Request Routing 17/20: Requests go straight from you to the AI provider.
  • Transparency 20/20: Source is public under MIT, so anyone can check how the key is handled.
  • Privacy 7/15: Nothing specific is known about its data handling beyond the key itself.
  • Maintenance 10/10: Actively developed: commits within the last three months.
  • Verification Confidence 1/10: Compiled from public documentation by an AI-assisted pass, not independently confirmed.

What was checked

Verification tier RESEARCH_ASSISTED, derived from the evidence below and not set by hand.

  • [REPORTED · RESEARCH] This listing was compiled by an AI-assisted research pass over the tool's public website, README and documentation. No person independently confirmed it.
  • [STRONG · SOURCE_SCAN] Supports a local model backend, so it can run with no cloud provider key at all. source
  • [CONFIRMED · SOURCE_SCAN] Most recent commit 2026-08-09, about 0 month(s) ago. source

How your API key is handled

Your API key is stored in your browser's local storage. Requests are sent directly to the AI provider.

Setup

Open the extension/app settings, paste your provider API key (kept in your browser), and pick a model.
