Hamster vs Notion
Notion holds the wikis, docs and databases your whole company writes, and it’s very good at that. Hamster does one narrower job. It drafts the Brief and the Plan your coding agents build from, using your Notion pages as context when you connect them.
Last updated
Free for 10 Briefs a month, and viewers are always free.
The short version
Notion gives you pages and databases for any purpose, shaped by your own templates, with Notion AI, Notion Agent on Business, and an MCP server your coding agent can use.
Hamster gives you a Brief drafted from your Notion pages, your code, your tickets and your calls, then a Plan with acceptance criteria on every task, in your repo and over MCP. It works when you write alone, and it keeps working when your designer and your engineers need to agree first.
You can also run both. Keep your wiki in Notion and bring the PRD you’re about to build into a Brief.
What Notion is good at
Notion holds wikis, meeting notes, handbooks and databases for every team in a company, not only product and engineering. You design the templates and views yourself, and Plus databases add subtasks, dependencies and custom properties. Pricing starts free, with Plus at $10 and Business at $20 per member a month billed yearly, or $12 and $24 billed monthly. Business includes Notion Agent for multi-step work across Notion, your connected apps and the web.
Notion MCP is hosted by Notion and uses OAuth. Claude Code, Cursor, Codex and other clients can search, read, create and update the pages and databases you can access.
Where it gets hard with a team
Say you’re adding team invites. You’re the PM, your designer owns the invite flow, and two engineers will build it across the API and the settings page. You write a thorough PRD in Notion, and your engineers comment on it. Then someone copies the requirements into the tracker as issues by hand, and the PRD and the issues start to drift.
An engineer’s agent reads the PRD through Notion MCP. This page carries no Plan and no record of who agreed to what, so the agent works out on its own which parts are decided and which are still open questions. Your engineers commented on the PRD, and they never signed off on it.
What Hamster does instead
Your team agrees on the Brief
You describe the invites work in chat, and Hamster drafts one Brief from the PRD, the invite code in the API and the call where seat limits came up, with each source cited. Your designer and both engineers edit that same Brief and mark it ready.
The Plan comes out of the Brief
Hamster turns the agreed Brief into a Plan of Tasks across the API and the settings page, with dependencies and acceptance criteria. On Team, the Tasks sync to Linear or Jira, so nobody copies the list by hand.
Every agent starts from what you agreed
Each engineer runs hamster sync, and the Brief, its Tasks, your Blueprints and Methods land as markdown that Claude Code, Cursor or Codex reads directly.
Keep Notion, let Hamster read it
Nothing you’ve written gets thrown away. Paste a Notion PRD into a new Brief, or have your agent read it over Notion MCP and create the Brief through the Hamster MCP. The setup prompt does the second one with the PRD you’re about to build.
You can also connect Notion under Connections. Hamster uses your pages as context when it drafts a Brief or answers a question, and can work with them on your behalf in chat. Hamster doesn’t sync Briefs or Tasks to Notion. Two-way sync is for Linear and Jira. See the Connections docs.
Set up Hamster and start from a Notion PRD
Paste this into Claude Code, Cursor or Codex in your repo, with the link to a Notion PRD you already have. You sign in once in the browser, and your agent does the rest.
Install Hamster in this repository. Fetch and follow https://tryhamster.com/plugin/install. Then, if Notion MCP is connected, read the PRD at <link to your Notion page> and create a Brief from it in my Hamster workspace through the Hamster MCP, keeping its requirements. If it isn’t connected, ask me to paste the page. Stop when you need me to sign in.
Notion costs less per member. Why pay for Hamster?
Notion is free to start, $10 per member a month on Plus and $20 on Business, billed yearly. Per person, that’s less than Hamster.
Hamster is free for 10 Briefs a month, and viewers are always free. After that it’s $40 per creator a month, so you pay for the people who write Briefs and not for everyone who reads them and marks them ready.
The $40 pays for what happens after the document. Hamster turns the agreed Brief into a Plan, gets it to your tracker and every agent on your team, and on Team a Cloud Agent can deliver it as a pull request.

Questions
- Can I keep writing PRDs in Notion and still use Hamster?
- Yes. Paste a PRD into a new Brief, or have your agent read it over Notion MCP and create the Brief through the Hamster MCP. Your team agrees on the Brief before it becomes a Plan.
- Does Hamster write back to Notion?
- Hamster doesn’t sync Briefs or Tasks to Notion. Two-way sync is for Linear and Jira. You can connect Notion under Connections so Hamster uses your pages as context and can work with them in chat.
- Does Notion have an MCP server?
- Yes. Notion MCP is hosted by Notion and uses OAuth. Clients such as Claude Code, Cursor and Codex can search, read, create and update content you can access. Notion MCP docs
- Which one should hold our product docs?
- Notion suits broad company documentation. Hamster holds what agents build from: Briefs, Technical Specs, Plans, Blueprints and Methods. Running both is a reasonable setup.
- I work alone. Is Hamster for me?
- Yes. Hamster drafts the Brief from your code and your docs, and the Plan gives your agent tasks with acceptance criteria. What you decide stays on the record for the next Brief, and it’s free for 10 Briefs a month.
Keep the wiki in Notion. Agree on the Brief before anyone builds.
