# Jotter

> Save context from any AI chat, load it in any other. A remote MCP server for cross-agent notes and conversation handoffs across ChatGPT, Claude, and Gemini. Operated by HelixMediaLabs LLC.

Jotter lets a person save ("jot") notes and conversation handoffs from any AI assistant and retrieve them from any other: cross-model handoff, new-thread continuation, and durable notes kept outside a single conversation. Every jot is private to its owner. Text only. It is user-controlled portable context, not automatic background memory, and it works across vendors (which built-in AI memory does not).

## How people use it (say it in any connected assistant)
- Save: "jot this" (a handoff of the chat or a plain note), "save this exactly" (word for word), "jot this to project-x" (tagged)
- Continue: "continue my last handoff", "load my latest jot", or "load jot X7K2-M9QT" (exact code)
- Second opinion: "load my latest jot and poke holes in it" (the loaded plan is treated as claims to check)
- Find: "what did I jot about pricing?" (titles, tags, opening lines, and the saving assistant), "list my jots", "list my project-x jots"
- In ChatGPT and Codex, "@Jotter" calls it by name
- Works in ChatGPT and Claude voice mode: say "jot this" out loud
- Limit: a chat that already hit its length or usage limit can't save; jot before the wall

## Pricing
- Free: 10 saved jots, kept forever
- Pro: $19/year (under $2/month), 5,000 jots, bought on jotter.fyi/upgrade, never inside a chat
