Grammarly AI Detector Alternative: No Account, No Scan Limits
If you already live inside Grammarly, its bundled AI checker is genuinely convenient — it sits in the same editor that fixes your commas. This page isn't here to tell you Grammarly is bad. It's here for the people who hit its edges: the account requirement, the per-scan limits, the basic free-tier results, and the fact that your text is processed on Grammarly's servers.
What Grammarly's AI detector actually offers
As of mid-2026, Grammarly includes AI detection in its free tier, but with constraints reviewers consistently note: you need a Grammarly account to use it, individual scans are capped (commonly reported around 10,000 characters — a few pages at most), and the free results lean basic, with the deeper sentence-level analysis sitting in paid plans that start around $12 a month. Independent accuracy testing is mixed — solid on unedited chatbot text, notably weaker on edited or polished AI writing, which reviewers describe as dropping toward coin-flip territory. To Grammarly's credit, they say plainly that no AI detector is 100% accurate. We say the same thing about ours.
Where AIScorely differs
Three places. First, friction: no account, no login, no scan caps — paste and check, as many times as you want, at any length. Second, transparency: instead of a bare percentage, you get every triggered signal highlighted in your actual text, plus a live score that moves as you edit — which turns the detector into an editing tool rather than a verdict machine. Third, privacy: the analysis runs entirely in your browser, so drafts, client work, and unpublished writing are never uploaded to anyone's server, ours included.
Already pay for Grammarly Premium and only need occasional checks? Use what you have. Checking long documents, checking often, checking confidential text, or wanting to see why something was flagged? That's what this tool was built for.
They also solve different problems
Worth saying clearly: Grammarly's core product is writing assistance — grammar, tone, clarity. AI detection is a side feature there. AIScorely does exactly one thing. The deepest version of that one thing is the evidence view: rewrite the highlighted sentences, watch the score drop, and learn your own tells along the way. Our guide on humanizing AI content pairs with it directly, and if you want the theory, start with the signs of AI writing.
Unlimited length, unlimited scans, evidence highlighted — free forever.
