Arche is a user-owned
context layer for AI

Arche captures, structures, and maintains your personal + project context over time so intelligence doesn’t reset when you switch tools or models. Secure, portable identity that plugs in anywhere—without surrendering ownership.

How it works

Continuity without lock-in

Unlike assistants that hoard data to improve their own models, Arche is built around user control, provenance, and reversibility— you decide what’s remembered, why it’s valid, and where it’s used.

📥

Capture

Pull signal from conversations, docs, decisions, and preferences. Keep personal and project context separate by default.

🧠

Structure

Turn raw text into a living context graph with embeddings + provenance. Relevance is computed, not guessed.

Inject

Selectively and safely inject only what’s needed into any AI interaction—any model, any tool, any agent.

Use cases

Built for real workflows

Compound intelligence across tools without re-explaining constraints, context, or history.

Developers

Carry coding preferences, architecture context, and project decisions across Cursor, Claude Desktop, ChatGPT, and agents.

Researchers

Keep hypotheses, sources, and conclusions consistent across models—without losing provenance or mixing projects.

Teams

Handoffs that don’t decay: shared project context, reversible updates, and selective injection by role and scope.

Portable, secure, reversible

Designed to keep you in control: what’s remembered, why it’s valid, and where it’s used.

Plugs in anywhere

MCP-native context injection into Cursor, Claude Desktop, Windsurf, and any compatible client.

Scoped + safe

Project and personal contexts are separated and can be selectively injected with clear boundaries.

Provenance + reversibility

Trace what’s remembered, why it’s valid, and roll changes back when needed.

Semantic retrieval

Query by meaning, not keywords. Similarity search surfaces the right context at the right time.

Context graph

Visualize relationships, clusters, and relevance—so memory stays inspectable, not magical.

Import the signal

Bring in exports, docs, resumes, and more. Arche extracts signal and keeps it organized.

Pricing
