Platform map
4StaX is built in four layers: memory, vault, market, and intelligence. kontxt is the shipping memory layer today. As more products launch, this hub will link to each one.
- AI memory layer (kontxt)npm package with a local SQLite vault (~/.kontxt/), MCP + CLI; cross-provider context that persists across sessions.
- Personal data vaultEncrypted storage, granular permissions, revocation, immutable consent ledger.
- Data marketplaceOpt-in monetization of attributed or anonymized data with verified consent trails.
- Training & annotationGig-style tasks and quality tiers built on the same vault so reputation compounds.
Customers own and control their data. The same foundation supports developer tools and enterprise deployments.
Hosted developer surfaces (roadmap)
These are planned cloud services. They complement the local npm package and MCP flow.
- In beta soon
Hosted memory API
Read and write memory from your backend so context persists across models and sessions. Policy and consent controls are built in.
- Roadmap
Annotation and quality programs
Consent-aware labeling and evaluation tied back to the vault, built for teams that need more than local MCP integrations.
