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.
Plugs into any MCP-compatible client


A living context graph
Arche turns fragmented signals—conversations, decisions, preferences—into structured context you can safely inject into any AI interaction.
A living context graph
Structured memory + semantic search across your context. View on desktop for the full interactive experience.
Prefers dark mode in all apps
Works at a Series B fintech startup
Uses Vim keybindings everywhere
Vegan—no meat, dairy, or eggs
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.
