AI Detector and Humanizer por ScanForAI

ScanForAI puts an honest AI-writing check one right-click away — and shows you why,
not just a number.

Scan for AI. Paste text, select-and-right-click, or hit "Scan page" to check a whole
article in one click, right-click any LINK to scan the page behind it, upload a file
(.docx/.pdf/.txt/…) straight from the popup, or paste a URL into the box (Ctrl+Shift+S opens the scanner anywhere). Signed-in users can flip
on Deep scan — the language-model pass — right in the popup, and set text type / ESL just
like on the site. You get a 0–100
score, a plain-English band (reads human → reads like AI), and the exact patterns that
fired — sentence rhythm, stock phrasing, predictability, structure — marked so you can
check the evidence yourself.

Clean up. Strip the machine formatting that gives pasted text away — long dashes,
curly quotes, the ellipsis glyph, invisible characters — without changing a single word.
You get a receipt of every change.

Humanize. Hand any text to ScanForAI's detector-guided rewriter: it reworks the
passages the detector flags while keeping your meaning, then shows the before/after.
Runs in the free dashboard (3 runs/day on a free account) — the extension sends your
text over with one click.

Fair to non-native writers. Detectors are known to over-flag ESL and formal writing.
ScanForAI detects the register first and eases formality tells, and every result says
which method ran — a signal, not a verdict.

Free, no signup. Anonymous scans and clean-ups work out of the box with fair-use
limits; a free account raises them and unlocks Humanize. Add an API key in settings if
you have one.

Honest by design: no detector — ours included — is 100% accurate. Formal, technical, or
non-native human writing can score high; edited AI can score low. Never use a result to
accuse anyone. https://scanforai.com
