# Fulcra - a durable, user-owned agent-native context store. Built for bridging the gap between agents and humans
## About
[Fulcra](https://fulcradynamics.com/) is a personal data platform: a context lake where a human collects and stores their real-world data and shares it with their AI agents. The data belongs to the user, not to any single agent, so it persists across sessions, agents, and harnesses. An agent running in Claude, ChatGPT/Codex, Hermes, OpenClaw, a cron job, or a Jupyter notebook can all read and write the same datastore.
What a Fulcra datastore holds:
* **Records of Data Types.** A Data Type describes something a user records; a Record is one saved instance. Fulcra ships a catalog of built-in Data Types, and users (or their agents) can create custom ones with fields of their own. Every Data Type has a Record Type: **Events** (a point or span in time) or **Metrics** (a measurable value over time). Records carry a start time (and an end time for spans), a source chain, and optional tags.
* **Files**, with full version history and restore. Files are a secure object store for anything an agent needs to keep: memory, notes, preferences, task boards, exports, dashboards.
* **Device-collected data**, if the user opts in. The optional [Context by Fulcra](https://apps.apple.com/us/app/context-personal-data-kit/id1633037434) iOS app can sync Apple Health, location, and calendar data into the same datastore in the background.
* **Shares and groups.** Users can share Data Types and files with other Fulcra users, and with groups so every member gets access. Shares are always read-only. Anyone who has a group's ID can join it and read everything shared into it, so never share private data with a group; share with specific people instead.
All Records and Files are encrypted at rest. Platform concepts are documented at [docs.fulcradynamics.com/fulcra-platform](https://docs.fulcradynamics.com/fulcra-platform/).
### What agents use Fulcra for
* **Durable memory across harnesses.** Back up an agent's memory, preferences, or working state to Fulcra files, then restore or clone it into a different agent or a fresh session.
* **Structured tracking.** Create a custom Data Type for anything (mood, market data, habits, build times, a project's progress), record values over time, and query them back later.
* **Multi-agent coordination.** Several agents working for the same user share files and records through one datastore and poll `data-updates` to learn what changed since they last looked.
* **Connecting with other people's agents.** When your user says "use Fulcra to connect to <person>", your agent and theirs exchange private messages, with both people's consent and nothing else shared. See [Connecting with another person's agent](#connecting-with-another-persons-agent).
* **Situational awareness.** Combine the user's own records with device data (sleep, workouts, location, calendar) when the user has connected those sources.
