You are viewing the hosted demo. A static site cannot call TypeSafe from the browser - the API sends no CORS header - so scoring here runs the small local heuristic described under Offline mode. Download this file and run it locally with a TypeSafe key for the real eight judgements: the bundled server relays the requests and makes them work.

What is actually asked

TypeSafe is a judge, not a writer. One draft goes out with eight independent judgements attached: two labels (how the post reads, what pulls people in), three graded qualities, and three risk checks. Nothing here is one opinion averaged into a number.

The arithmetic

Risk multiplies rather than adds. In an earlier version it was an 18% additive term, which meant a post could be flagged as likely to be removed and still score 78, and fixing the removal risk entirely bought about ten points. Now the thing that gets a post deleted is the thing that moves the number.

How versions are built

Since the model cannot write, every version is assembled from your own sentences. A dozen title treatments and ten body treatments are generated, then combined with each other, which is where the volume comes from: around a hundred and twenty complete posts per run.

Titles and bodies are scored separately, in two parallel requests, so all hundred and twenty combinations can be ranked from about seventy judgements rather than seven hundred. The best three are then re-scored in full, against the same eight judgements as your original, so the number you are shown is measured rather than predicted. Three requests, about a hundred posts considered.

How much change

Each version is compared with your draft word by word, and the proportion that differs becomes its change figure, printed on every option. The three settings are thirds of that spread: Light touch is the third that stays closest, Rebalance the middle third, Rewrite hard the third that moves furthest. Thirds rather than fixed percentages, because a fixed cut-off behaves differently on a two-line post than on six paragraphs and can leave a setting with nothing in it. Switching between them re-ranks instantly from scores already in hand, so it costs one confirming request rather than a full rebuild.

What the bands mean

• 78 and up — worth posting as is.
• 62 to 77 — solid, with one signal left on the table.
• 45 to 61 — readable, but nobody has a reason to reply yet.
• Under 45 — the point is not landing, or the post will be pulled.

Offline mode

Offline scoring runs a small local heuristic. No network, no key, no model. It scores every combination directly rather than estimating, so rewrites work offline too. Useful for a feel of the tool, not for a real read.

Shortcuts

• Ctrl + Enter — score the draft
• 1 to 4 — switch tab, when not typing

Where things are kept

The server in this file only relays requests to TypeSafe. Your key, your draft and your run history live in this browser's local storage and are never sent anywhere else. Images stay in the page and are never uploaded — only the description you write about them is scored.
