Checkumi
Free · built for agents and people

Two-level checklists for the stuff that slips — SEO, launches, code review. Reuse one checklist across projects and manage it in one place. Hand your agent a link to work through every item, every time.

Public lists are readable by anyone.

Readable for you. Parseable for agents.

One checklist, three ways to read it — and nothing extra to learn.

TWO LEVELS

Groups and items. That’s it.

Deep trees make agents wander. Two levels keep every list scannable and every check concrete.

APage basics
Each page has a unique title
Meta description says why it matters
Canonical points to the right URL
BCrawling & indexing
SHARE A RUN

Hand it to a person.

checkumi.com/runs/15

Send a run link to a teammate, a friend or family. They tick items without signing up.

AGENT-READY

Markdown and JSON, same link.

/l/seo-launch.md.json

Paste the link into a prompt, or fetch .md / .json. Stable item IDs make pass/fail reports easy.

01

Write a two-level list

Groups and checks, each with an optional note on what “pass” means.

02

Share the link

Keep a list private or make it public, and share one link with people and agents.

03

Hand it to your agent

The link always serves the latest version, so updating the list updates every run.
