# SkyOS

> SkyOS is the main memory for Claude, ChatGPT or Codex. It turns what you decide in your AI chats into short, dated notes, kept per project, so you don't re-explain your project in a new chat. If you use more than one of these apps, they share the same notes.

## What it does

- Connects to Claude, ChatGPT and Codex as an MCP server. Every connected app reads and saves the same notes.
- Notes keep the exact numbers, names and reasons you gave, not a summary. Each note is dated, and relative dates ("next Friday") are saved as real ones.
- The AI is told today's date and when the memory was started. When a note older than a month holds a number or a status, it says when it was true ("as of 18 August, …") instead of presenting it as current. It asks whether such a fact still holds only before it goes into something public, and asks once when a deadline in a note has passed with no word on how it went.
- Each new chat starts its own memory, so projects stay apart. To pick one up in a new chat, say "continue" and the memory's name, shown on the Memory page at app.skyos.ink: the chat carries on with the same notes and the last few messages.
- Notes are rewritten when you change your mind. You can read, edit, export and delete them on the dashboard at app.skyos.ink.
- SkyOS keeps only the last five exchanges of each chat, deleted after 30 quiet days. Everything older exists only as notes.

## Pricing

- Free during the beta, up to 1,000 saved messages a month.
- Claude, ChatGPT and Codex all work on free plans.
