Every AI session starts knowing your project.
The brief your AI reads before every session, so it picks up where you left off instead of starting over.
Free to start, no credit card. Works with Claude and ChatGPT; your context stays yours.

Same prompt. Same project. One of them forgot.
Left started cold. Right read the brief. You only typed the prompt once.
This is what your AI reads.
Four plain slots: what you shipped, what you decided, what's open, and what'll bite you. Every connected session starts already holding it.

Works in Claude Code, Cursor, Codex, ChatGPT & Claude.ai.
Most AI memory is a black box. Yours isn't.
Other tools quietly stash your context in a vector store, where you can't predict what will surface and can't take any of it with you. DeerDawn's memory is a brief you can read: four plain slots for what you shipped, what you decided, what's open, and what'll bite you. If a line is wrong, you fix it. If you leave, you export it.

No black box. Just the brief.
Every tool you connect starts each session already holding that brief.
We run DeerDawn on DeerDawn.
We build DeerDawn using DeerDawn. Every session here starts already briefed.
The brief reads like a teammate catching you up: here's where you stopped, here's what's next.
Add once. Available everywhere.
Describe your project in the DeerDawn dashboard, or paste a response from any AI. From then on, every tool you connect gets that context automatically.
Paste a description, import a CLAUDE.md, or ask any AI to summarize your project and paste the response into DeerDawn.
Add the DeerDawn MCP server to Claude Code, Cursor, Codex, Claude.ai, or ChatGPT. It's one URL and a browser sign-in, with no API keys to manage.
Every tool you connect gets your current task, stack, decisions, and open questions, on every device, so no session starts cold.
Your know-how, in every agent
The same brief that catches up every session now carries your AI workflows too. Write a workflow once and DeerDawn writes it into each tool's native format automatically. See how it works.
Author a workflow as plain markdown: a review checklist, your testing conventions, a deploy runbook.
It lands in each tool's native format (Claude Code, Cursor, Codex) on every session start, so your agents work your way everywhere.
Edit it in one place and every agent updates. Your local tweaks stay intact.
Months of context. One file.
A Trail is everything your AI learned about a project — the task, the decisions and why you made them, the files that matter, the traps you already hit — written to one portable file. Hand it to a teammate and their first session starts where yours left off. See what is in one.
The context sync loop and the services around it — retries, merge semantics, and the landmine that breaks npm ci.
The Trails feature itself, mid-build: why the format is plain JSON, why import cannot clobber, and two gate bugs found the hard way.
The public site and its landing pages, including the decision to publish an unflattering measurement.
Nobody has published one yet — the gallery opens with the feature. Until then these three are examples, exported from real projects through the same redaction gate you would use. Download one and open it in a text editor; it is plain JSON, and that is the point.
The one part of your stack that gets smarter every session.
Models get swapped and tools come and go. The brief is what accumulates, and it stays yours.
Each thing you ship, decide, or hit a wall on gets written back. The brief is sharper tomorrow than it was today.
The brief isn't tied to Claude, Cursor, or ChatGPT. Switch your stack and the memory stays put.
Your brief is structured and exportable. Take it with you anytime, and the next tool starts just as caught up.
For people running more projects than they can hold in their head.
The main repo, the side project you touch on weekends, the client build you left mid-decision a month ago. DeerDawn keeps a brief for each one and knows what they share, so picking any of them back up never starts with reconstructing it.
Never start cold.
Free for everything within a project, with unlimited projects. Pro is $12/mo or $96/yr (save $48) for everything across them, and the founding rate locks in at half the eventual $200/yr.
