Detect AI content
in about a minute.
Paste the text. We'll tell you how likely it was written by AI — and show you the sentences that gave it away. Your first check is free, no signup.
AI writes most things now. You can't always tell.
Essays, pitches, emails, news copy — a lot of it isn't human anymore. Reading it by hand is slow, and even careful readers miss the tells. So who do you trust?
A second opinion you can defend.
We run the text past four different AI models, weigh what they each think, and hand back a single score plus the exact sentences that look generated. Fast enough to use mid-edit.
Three steps. About a minute.
Spot the AI, check the facts, then lock your own work to a ledger so no one can claim it later.
Why people actually keep it open
Less guessing. Fewer awkward conversations.
Skip the slow read
What used to take a full afternoon of squinting now takes about a minute.
Catch what you'd miss
AI prose is smooth on the surface. We flag the bits that aren't quite right.
Bring receipts
Hand your editor or your professor a score, not just a hunch.
Publish without flinching
Check your own work before someone else does. Hit send with your shoulders down.
"Every submission goes through askCPL before it hits my desk now. It's caught a few pieces I would've waved through, honestly."
"I needed something I could actually show a student — a score with reasoning, not a yes-or-no I can't defend in a meeting."
"It's fast enough that we just run it on everything. The sentence-level highlights are what got the rest of the team to switch."
