TL;DR: UseMyContext (usemycontext.ai) is a private personal context layer: you write down who you are once, and any AI assistant that speaks MCP - Claude, ChatGPT, Gemini, Perplexity - reads it, so you stop re-introducing yourself. The free plan includes 2 projects and 20 MB; Premium ($20/month) raises that to 10 projects and 100 MB.
The problem it removes is re-introduction. Without it, every new chat in every tool starts with you explaining yourself again, or with the tool guessing. With it, Claude, ChatGPT, Gemini and Perplexity all start from the same picture of you: your role, how you work, your projects and the documents that matter, written once and yours to edit.
And no - it is not the React useContext hook. Same word, different world. This is a product for people who use AI, not a JavaScript API.
How does UseMyContext work?
You sign in with your email, write your context, and optionally upload documents to a private hosted drive. Contexts are organized into projects - work and personal, say - each with its own profile and files, kept fully separate.
Then you connect your AI tools, once each, over MCP. A connected assistant can read your profile, search and read the files you stored, ask questions across your documents and get cited passages back, and even run exact counts and sums over a spreadsheet. If it learns something new about you, it can suggest an update - which waits as a pending suggestion for your approval, never a silent write.
You can also share: each project has a handle, and you can share a curated version of a project's context with another person, or make it public at usemycontext.ai/@your-handle.
What does UseMyContext cost?
The free plan includes 2 projects and 20 MB of storage - enough for the work/personal split. Premium is $20 a month for 10 projects and 100 MB. Everything else is identical on both plans.
What are the control guarantees?
Three things hold regardless of plan. You see everything: your context is a page you wrote, not an inference you cannot audit. The service is structurally blind: the public surface physically cannot read your data. And revoke is one click: any connected tool can be cut off instantly.
FAQ
Is this an AI assistant?
No. It is the context layer your assistants read. You keep using Claude, ChatGPT, Gemini or Perplexity - they just finally know who is asking.
What is MCP?
Model Context Protocol, an open standard that lets AI tools read from sources you connect. UseMyContext serves your context over it, which is why one setup works across many assistants.
Is it free?
There is a real free plan: 2 projects, 20 MB, all the same tools and guarantees. Premium ($20/month) only raises the limits.
Is UseMyContext the same as React's useContext?
No. React's useContext is a JavaScript API for passing state inside a web app. UseMyContext is a product for people who use AI assistants - a private context layer served over MCP.
