Works in ChatGPT & Claude.ai — no install needed

Never start cold.

Cold vs. briefed

Same prompt. Same project. One of them forgot.

Left started cold. Right read the brief. You only typed the prompt once.

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 — add new fields there
  • PR #46 left dead auth code — 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 you can't read, can't correct, and can't take with you. DeerDawn's memory is a brief you can see — four plain slots: 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
  • Stored as vectors you can't read
  • You can't see or correct it
  • Locked to one tool

No black box. Just the brief.

That’s the brief every tool you connect starts each session already holding.

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 — one URL, sign in through your browser, no API keys.

3
Every session starts briefed

Your current task, stack, decisions, and open questions are handed to every tool you connect — across devices, so no session ever 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

Only structured brief updates are stored — never your raw conversations. 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 — 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 on every session start — Claude Code, Cursor, Codex — so your agents work your way everywhere.

Stays in sync

Edit it in one place and every agent updates. Local tweaks are preserved, never overwritten.

Compounding

The one part of your stack that gets smarter every session.

Models get swapped. Tools come and go. The brief is the thing that accumulates — and it's 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 — no lock-in, no re-explaining.

For people whose work can't afford amnesia.

Builders shipping real projects across Claude Code, Cursor, Codex, Claude.ai, and ChatGPT — where re-explaining the project every session is the tax you stop paying.

Never start cold.

Free for your first project. Founding Pro is $10/mo or $96/yr — two months free, and the founding rate locks in at half the eventual $200/yr.
