What is SaveSlot
Memory isn't enough. An agent can remember a lot and still act on a plan you changed yesterday, a number it guessed, or two values that disagree. SaveSlot keeps the current state of the things you work on with AI, and tells every agent where each value came from and how sure it is.
SaveSlot is a Personal Agent State Layer. The core idea is the Trusted State View: each record carries its source, the time it took effect, its version history, who may read or change it, and one of four trust markers.
What you get
- Slots. A slot is a workspace for one part of your life or work, for example Health or My project. It holds tables your agents read and write.
- Your own agents. SaveSlot does not answer questions itself. You connect the agent you already use (Claude, ChatGPT, Claude Code, Codex, Gemini, Grok, or any assistant that supports remote MCP), and it reads and writes your slots.
- Trust markers. Every value is Confirmed, Inferred, Unknown or in Conflict. Agents see the marker, so an estimate is never read back as a fact.
- History, not overwrites. A correction adds a version. Old values stay, with who changed them and why, and you can restore one.
- Data sources. Apple Health, Garmin or a file import fill the official tables of an extension automatically.
- Pages. Your agent can publish a small page, such as a sleep chart, that reads your tables directly in a sandbox.

What SaveSlot is not
- Not a memory tool. It works alongside memory features in your assistant. Memory keeps what was said; SaveSlot keeps what is currently true, as far as anyone knows.
- Not an agent runtime or workflow engine. It does not run your agents or schedule their work.
- Not the record of truth for other systems. Your bank, your calendar or your training app stays in charge of its own data. SaveSlot keeps a traceable copy of what your agents need, and marks where it came from.
Hosted or self-hosted
The hosted service runs at app.saveslot.ai. The core is open source under Apache-2.0 and can be self-hosted from GitHub. Both expose the same ten MCP tools. This documentation covers the hosted service unless it says otherwise.
