Works in ChatGPT & Claude.ai with nothing to install
Never start cold

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.

✕Cold session: “Catch me up, what were we building?”
✓Briefed session: your AI opens knowing the task, the last decision, and what’s still open.

Cold vs. briefed

Same prompt. Same project. One of them forgot.

The brief

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.

Shippedwhat's done
  • Stripe webhook handler: success + redirect
  • Remote MCP live for Claude.ai & ChatGPT
Decidedchoices locked in
  • jose over jsonwebtoken for JWT verify
  • MCP-first launch: no raw transcript storage
Openwhat's still in flight
  • First-week activation rate
  • First-sync timing across tools
Landminewhat'll bite you
  • normalizeContextForSchema drops undeclared fields, so add new fields there
  • PR #46 left dead auth code, so don't reference it

Works in Claude Code, Cursor, Codex, ChatGPT & Claude.ai.

No black box

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.

Opaque memory
  • A fuzzy retrieval you can't predict
  • Can't pin down or correct what surfaces
  • Locked to one tool

No black box. Just the brief.

Every tool you connect starts each session already holding that brief.

Dogfooded

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.

How it works

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.

1
Add your project

Paste a description, import a CLAUDE.md, or ask any AI to summarize your project and paste the response into DeerDawn.

2
Connect your tools

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.

3
Every session starts briefed

Every tool you connect gets your current task, stack, decisions, and open questions, on every device, so no session starts cold.

One brief, every tool

Each project keeps one living brief: status, goals, decisions, tech stack, current task. Every AI tool you connect reads from the same brief.

Briefed on every device

Add to the brief on your laptop, pick it up in Claude Code on your desktop. The brief lives in the cloud and follows you.

Private by design

DeerDawn stores structured brief updates, never your raw conversations. You can revoke any connected tool at any time.

Now in beta

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.

Write once

Author a workflow as plain markdown: a review checklist, your testing conventions, a deploy runbook.

Runs in every agent

It lands in each tool's native format (Claude Code, Cursor, Codex) on every session start, so your agents work your way everywhere.

Stays in sync

Edit it in one place and every agent updates. Your local tweaks stay intact.

Compounding

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.

Every session refines it

Each thing you ship, decide, or hit a wall on gets written back. The brief is sharper tomorrow than it was today.

It outlives any single tool

The brief isn't tied to Claude, Cursor, or ChatGPT. Switch your stack and the memory stays put.

Switch tools, keep the memory

Your brief is structured and exportable. Take it with you anytime, and the next tool starts just as caught up.

For people whose work can't afford amnesia.

Builders shipping real projects across Claude Code, Cursor, Codex, Claude.ai, and ChatGPT, who are done re-explaining the project at the start of every session.

Never start cold.

Free for your first project. Founding Pro is $10/mo or $96/yr (save $24), and the founding rate locks in at half the eventual $200/yr.
