Your first evaluation
Paste a prompt on the front page and press the button, or sign in and use the editor. Drop a text file on the page if that is easier. An evaluation takes about a minute and costs one credit.

How an evaluation works, what the report is telling you, and what to do with it.
On this page
Reading the report
The top of a report gives you a score out of ten, a letter grade, and the level the prompt reached. Below that, each of the eight dimensions carries its own score, the line of your prompt that earned it, and what would raise it.
What the levels mean
Novice is a bare instruction. Intermediate adds role framing or a basic output rule. Advanced has named sections, a specified output shape, and some edge cases handled. Expert adds inert input, stated precedence, defined failures and bounded retries. You reach the highest level you fully clear, not the highest you touch.
The one edit to make first
Every report ends with a single change, written out before and after. It is chosen for how much it moves the score rather than how easy it is, so start there before working down the dimension list.
Keeping a library
Save a prompt with a name and it is offered in a dropdown next time you submit. The library is free and unmetered. You can keep prompts with no credits at all, and a short draft saves even when it is too short to be worth evaluating.
Comparing drafts
Open an evaluation and choose Revise. The editor opens with that prompt, and the evaluation you get back is linked to the one it came from, so a chain of drafts reads as a chain rather than as unrelated results.
Sharing and exporting
A share link lets somebody read one review without an account. You can also download an evaluation as JSON or Markdown, or print it. Downloads are named from the review’s own link, never from anything you wrote.
Credits
One credit is one evaluation. Your account page shows what arrived, what was spent, and why. Every movement is a line, including refunds, so a balance can always be explained rather than just asserted.
Deleting and restoring
Deleting an evaluation moves it to the trash, where it stays until you empty it. Trashed evaluations are hidden from your history and from any share link, and restoring one puts it back exactly as it was.
