OnFabric

OnFabric (Fabric) builds portable consumer context for the AI internet, letting people bring their full digital self into their favourite LLMs so agents become truly personal assistants instead of generic chatbots. Its open-source context-use tool converts personal data exports (ChatGPT, Claude, Instagram, Google, Netflix, Airbnb) into a local, searchable memory store and enriches OpenAI-compatible traffic through a local proxy, while the hosted Fabric product exposes that personal context to ChatGPT, Claude and Gemini via a Model Context Protocol server. OnFabric is a Silicon Valley consumer-data startup backed by Forerunner Ventures.

OnFabric is profiled on the APIs.io network. Tagged areas include Company, Ai, Artificial Intelligence, AI Agents, and Personal Context.

OnFabric’s developer surface includes documentation, getting-started guide, engineering blog, support, signup flow, CLI, changelog, and 14 more developer resources.
