Free Sapling AI detector alternative

Check your textHow to read your AI detector score
The AI detector gives you a single number from 0 to 100. It is the estimated chance that AI wrote the text, not a yes or no. Here is what each band means.
Probably a person
Reads like human writing. We did not pick up the patterns a model tends to leave behind.
Hard to say
Some of it leans one way, some the other. Read it yourself before you draw a conclusion.
Probably AI
This has the marks of machine-written text. Read it closely before you conclude anything.

AI Detector vs Sapling
Sapling offers an AI detector aimed at educators, reviewers and businesses, alongside an API and team features. It runs on a freemium model that caps free checks at around 2,000 characters and steers heavier users toward paid plans. This tool is a free, no-login detector for anyone who just wants a quick read on a piece of text.

When Sapling fits better
If you need detection wired into a product or workflow through an API, or features built for a team, Sapling is worth a look. For a one-off personal check, a free detector covers the core need without setup.
Where your text goes
The check happens in memory on our own server. As soon as you have a score, your text is dropped. No logs, no database, no training set.
There is no account holding a history of your checks either.
