Contexter

Contexter is an AI-powered documentation assistant that runs entirely in your browser - no cloud, no API keys, no data leaving your device. HOW IT WORKS Point it at any page - internal docs, wikis, API references, runbooks and Contexter indexes the content locally on your device, then ask anything. It finds the relevant sections and answers instantly using an AI model running on your GPU. YOUR DATA STAYS YOURS Most AI tools send your content to external servers for processing. Contexter never does. Indexing, embeddings, and inference all happen on-device using open-source language models. Your confidential documentation is never exposed to any third-party server - not even ours. WHO IT'S FOR - Developers navigating API documentation - Teams working with internal or confidential knowledge bases - Knowledge workers who need fast answers without leaving the browser - Anyone who cares about keeping their data private FEATURES - Fully on-device: LLM and embeddings run locally via WebLLM - Works on any page: internal tools, private docs, public sites - Semantic search: finds answers by meaning, not just keywords - No account required, no subscription, no API key - Works offline once models are downloaded
