Capture the work.
Chats, files, calls, decisions, agent runs, and notes land in one local-first markdown vault.
Private beta
Your AI tools share one thing in common. You.
And you're tired of being the integration.
ChatGPT doesn't know what you told Claude. Claude doesn't know what Cursor changed. Cursor doesn't know about the customer call you had this morning. Right now, you are the human USB cable copy-pasting context between tabs all day.
deeda Think is a private app on every device you own — web, desktop, mobile, all native — where every chat, file, and decision lands in one searchable notebook. Every AI tool you use reads from the same one. Your Claude knows what your Cursor wrote yesterday. Your Codex knows what your ChatGPT decided last week.
What it is
A notebook your tools can share.
deeda Think sits under the apps you already use. It does not replace ChatGPT, Claude, Cursor, Codex, or Gemini. It gives their output a durable place to live next to your files, calls, decisions, and team context.
Give it an address.
ThinkIDs attach time, domain, and lineage so humans and agents can find the exact thing later.
Wake up briefed.
The next session starts from the vault, not from another prompt where you re-explain everything.
ThinkIDs
The minute it happens, it has an address.
A ThinkID is the stable handle for a piece of work: a chat turn, a saved file, a refund decision, an agent tool call, a project note. Sort by time, filter by domain, trace what replaced what.
That means an agent can ask the same question a human would ask: what changed after the customer call? The vault already knows where to look.

Humans and agents
One vault. Different interfaces.
The human experience is the app. The agent experience is the controlled interface into the same vault. There is one lifecycle, one account, and one billing state behind both.

Why it exists
App memory is useful. Work memory has to travel.
Product-native memory is good at helping one product remember local preferences and nearby context. Your work crosses products. deeda Think is the layer that keeps the durable work object alive after the chat window, model, or editor session changes.
Lives inside one product. Helpful, but usually scoped to that product's session, project, or rules.
Lives in your vault. Files, decisions, chats, and agent runs can be read by every approved surface.
You keep the tools you like. They finally share a durable memory layer underneath.
Local-first
Plain files, not a black box.
Your vault is a folder of readable markdown with project structure, frontmatter, references, and generated context packets. Open it in deeda Think, another editor, git, or the terminal.
