Free AI Detector — No Credit Card, No Catch
Detect AI-generated text, images, and video for free — 20 checks every single day, refreshed automatically, with no credit card required. Token-level results, not just a percentage.
CheckAI is a genuinely free AI detector: 20 checks every day, refreshed automatically, with no credit card and no sign-up wall to start. The free tier gives the same full word- and sentence-level results as paid use, across text, images, and video.
Detect AI for free in 3 steps
Open the detector
No paywall to get started. Claim your free daily credits and run your first check right away.
Paste and detect
Check text, images, or video. Each detection uses one of your 20 free daily credits.
Get token-level results
Even on the free tier you get the full word- and sentence-level heatmap, not a watered-down score.
Free that is actually usable
Real daily quota, full results, and no card required to start.
Truly free daily quota
20 credits every day, refreshed automatically every 24 hours — not a tiny one-time trial.
Full token-level results
The free tier shows the same sentence-level heatmap as paid use, not a blurred-out preview.
No sign-up to begin
Start checking without filling out forms first. Create an account only when you want to save work or buy more.
Upgrade only if you need to
Need more than 20 a day? Pro and pay-as-you-go packs are there — but most people never hit the limit.
How can the AI detector be free?
CheckAI runs on a freemium model: everyone gets 20 detection credits per day at no cost, and heavier users pay for more. The free quota is generous on purpose — it covers most people's everyday checking — and it is funded by the Pro subscriptions and credit packs that power users buy.
What you get for free
Full token-level detection for text, plus AI image and video detection, all on the free daily credits. There is no separate "lite" detector for free users — you get the same engine and the same sentence-level evidence, just metered by the daily quota.
When it is worth upgrading
If you check content all day — say you run an editorial team or process submissions in bulk — 20 daily credits may not be enough. That is when Pro (more daily credits) or pay-as-you-go packs (credits that never expire) make sense. For everyone else, free is genuinely enough.
Free AI detector FAQ
Is it really free?+
Yes. You get 20 detection credits every day at no cost and no credit card. You only pay if you need more than the daily free quota.
Do the free credits refresh or expire?+
Your free credits refresh every 24 hours, so you get a new batch of 20 each day.
Do I need to create an account?+
You can start checking without a sign-up wall. An account lets you save history and buy more credits, but it is not required to try the detector.
What is the catch?+
There is no hidden catch — the free tier is metered by the daily credit quota, and the same full token-level results apply. Heavy users upgrade; everyone else stays free.
Is my content stored?+
No. Submitted content is never stored or used for training.
