Use cases
Specs you can build, traced to why.
PRDs that reach your team cite the customers behind them, can read the code they describe, and are marked shipped when the pull request merges green.
Request
Draft a PRD to fix payout delays for top creators.
Creator Payout SLA & Transparency
- 1Pull every payout-delay signal from interviews, tickets and Slack
- 2Quantify settlement time against the 48-hour baseline
- 3Propose a payout SLA with in-app status
- 4Define success metrics and rollout risks

From spec to merged.
- 1
Read the why
Every claim in the PRD links to the customer signal behind it.
- 2
Check it against the code
With a repo connected, Composer reads the code it describes and won't cite files it never opened.
- 3
Pick it up in your tools
Linear issues with sub-issues, a Jira issue, or a handoff to Claude Code or Cursor.
- 4
Merge and move on
One line in the pull request links it. When it merges with passing checks, it's shipped.
The why, one click away
Hover any citation in a spec to see which customer said it, where and when. Open it to read the signal in full.
- Problem, evidence, scope and success metrics in one place
- Contradictions with earlier specs are flagged before you start
- Code references are re-checked against the repo every night
Payout delays are the leading driver: settlement now takes 5–7 days#1#2.

“I waited a week for my payout. That's never happened on other platforms.”

Shipped means merged and green
Add an Euler-Spec line to the pull request description, or link it in the app. The delivery chain follows the work from the issue to the merge and beyond.
- A branch-name match waits for someone to confirm it
- Every recorded CI run has to pass
- Unknown means Euler can't see it, never that it passed
Delivery chain
From tracker issue to outcome review. Unknown means Euler can't see the evidence, never that it passed.

From your editor
Point Claude, Cursor or any MCP client at Euler with a workspace token, and ask about customers without leaving your editor.
- Search signals and read specs from your editor
- Read, write and push are separate token scopes
- Pushes come back as a link for a person to approve

Most of it is about not knowing when a payout will land, rather than how fast it is. Partner creators raise it most often.

What you get.
- Dependencies drawn
- Blocks, follows and relates edges between features, with loops refused.
- Effort from history
- Estimates that draw on your team's measured delivery times, the roadmap and the code.
- Linear sub-issues
- Push a spec as a parent issue with one sub-issue per task in its breakdown.
- Handoff
- Open a spec in Claude Code, Cursor, Lovable, v0, Bolt, Replit or Claude.
- Exports
- Markdown, PDF, Word or JSON for anything else.
- Outcomes
- After the Linear issue closes, see whether customer complaints on the theme actually fell.
What it won't do.
Write your code
It hands specs to the tools that do, and keeps track of what shipped.
Push behind your back
Agent-initiated pushes to Linear or Jira wait for a person to approve.
Promise dates
Schedules are relative windows learned from your delivery history, never invented calendar dates.
Questions, answered.
An Euler-Spec line with the spec's id in the PR description, a link made in the app, or a PR Euler opened itself. A branch-name match is only a suggestion until someone confirms it.
Yes. Import your template from a PDF, paste it in, or build it by hand, and Composer drafts into its sections.
Yes, for feedback in and specs out. Outcome measurement after launch currently needs Linear.
Stop drowning in feedback. Start shipping the right thing.
We're putting the agents through their paces. When early access opens, the waitlist hears first.
