A flexible, relational tool for the things you keep track of — built for one person or a few people working together, not an org chart. Define your own models and fields, collaborate in real time with full version history, and let agents like Claude manage it all through a built-in MCP server.
No seats. No per-person pricing. Adding people to work with you will never cost extra.
Define record types with exactly the typed fields you need — text, number, date, currency, rating, select, relation, rich documents, files, location and more.
Link records across models with relation fields, with inverse names and semantics that keep both sides of every connection in view.
Every edit is snapshotted. Browse the timeline of any document and restore an earlier version with a single click.
Changes a teammate makes show up without a reload, and every edit autosaves as you type.
Store files alongside your data, with custom fields, thumbnails, and OCR-powered image search across your workspace.
Simplist is its own MCP server, so AI agents like Claude can create models, write documents, and manage files for you — the human UI is the companion.
