NO PART

No Part

The best part is no part. Paste a plan. See what to delete.

No Part reads a plan the way a hard-nosed engineer would: every requirement has to explain why it exists. It questions each one, deletes what can go, simplifies what stays, and only then talks about speed and automation. You get a short verdict — what to delete, what to keep, and one sentence of why.

The five steps, in order

  1. 1

    Question every requirement

    Each one has to trace back to physics, law, or a real customer need. “It came up in a meeting” is none of those.

  2. 2

    Delete every part you can

    If you never have to add anything back later, you did not delete enough the first time.

  3. 3

    Simplify what remains

    Only after the deleting is done — otherwise you polish parts that should not exist.

  4. 4

    Accelerate cycle time

    Whatever survives should move faster. Most schedule risk was in the parts you just removed.

  5. 5

    Automate last

    Automating a step that should have been deleted is how bad processes become permanent.

The order matters. Skipping ahead to step five is how teams end up automating things that should never have been built.

Try it on someone else's plan first

Below is a fictional spec for a grocery app — eighteen requirements, most of them familiar, several of them doomed. Run the pass and watch what happens. This one is free.

Pantry — a fictional grocery & pantry app — read the spec
Pantry mobile app — feature spec, v3 draft

1. Users can scan grocery barcodes to add items to their pantry.
2. The app tracks expiry dates and reminds people before food goes bad.
3. Users can build a shopping list and check items off in the store.
4. Shopping list creation should also be possible from the pantry screen.
5. AI-powered recipe ideas personalized to each user's taste profile.
6. A social feed where users share what they cooked, with likes and comments.
7. Badges and streaks to reward users for logging meals every day.
8. An Apple Watch companion app for glanceable pantry stats.
9. Voice assistant integration so users can add items hands-free.
10. A referral program that gives users points for inviting friends.
11. Six color themes and seasonal app icons to keep the interface fresh.
12. Integrations with Slack, Notion, and two supermarket loyalty APIs.
13. Eventually, a marketplace where local farmers can sell surplus produce.
14. Blockchain-verified provenance tracking for premium ingredients.
15. An onboarding tour that ends with confetti when the first item is added.
16. Competitors have meal-planning calendars, so we need one too.
17. A cookie consent banner and a privacy policy page.
18. Users can export their pantry and lists as a CSV file.

The spec is fictional, but you have sat in the meeting that wrote it. The pass is deterministic: same plan in, same verdict out.

Paste up to 8,000 characters of plan, spec, landing page, or process. One payment of $9, once — not a subscription. You get the full pass on a results page and a copy by email.

0 / 8,000 characters

No account. Your email is asked for once, at payment, so the result can be sent to you. The full pass appears on screen right after, too.

What this is, honestly

The pass is a fixed, testable rubric — the same rules every time, written down in code, not improvised by a chatbot. It will not know your market. It will notice the feature that exists because a competitor has it, the automation that arrived before the manual version, and the three requirements that are secretly one. Most plans die from addition. This is subtraction, as a service.
