Here's the thing. You ask Claude a question. Before it reaches the model, Contextify intercepts it — on your device — finds the most relevant pieces of your history, and injects just that into the call.
The AI only sees what it needs. Nothing more ever leaves your machine. Not to us. Not to anyone.
The thing is — this isn't a hard problem to solve. It's a layer that's been missing.
Contextify sits on your device. It reads your history, builds a timeline, and at the exact moment you ask something, it finds the relevant pieces and injects them into the call. Silently. Instantly. Entirely on your machine.
No external API. No cloud step. No middleman. The AI gets context. Your data goes nowhere.
Runs entirely on your device. No external calls at any step — not during indexing, not during retrieval, not during injection.
Authorize Contextify to read your communication history. All processing happens locally — nothing leaves your machine.
Messages are compressed on-device into structured summaries — decisions, threads, outcomes. A complete timeline of your working life. No raw data stored. No external calls made.
When you send a query to any LLM, Contextify intercepts it, retrieves only the most relevant context from your local timeline, and injects it — on the fly. The model gets what it needs. Nothing more.
Contextify works as a background context layer — compatible with any LLM interface. The AI changes. The context layer stays.
Here's the thing about trust — you can't verify what a cloud service does with your data. You can verify what runs on your own machine.
Everything: indexing, retrieval, injection — happens locally. No account. No server. No step where your data is anywhere but yours.
The LLM only ever sees the context it needs for your query. Your full history is never passed to any model — local or remote.
Context retrieval and injection happen entirely on-device. No cloud service, no intermediary. Nothing leaves your machine at any step.
The entire processing pipeline is MIT-licensed. Read every line of what we do with your data on GitHub.
Connect your accounts. Contextify builds your timeline on your machine. The next time you ask an AI something — it already knows what it needs to know.
