We file it under AI content detection, the category of tools to check whether content is AI-made, and it also overlaps with education and tutoring. The category lists 9 verified tools on this site.
The publisher is COMPILATIO SAS, based in France. The service launched in 2005, which gives it some track record.
Who is it for?
It is mostly useful to these profiles: teachers, students, and researchers. The need it covers is simple to state: check whether content is AI-made.
Compilatio is a good candidate if:
- you want to try before paying
- you plan to connect it to your tools or automations through its API
- you must keep your data in Europe or on your own machine
Before deciding, run a trial on a real task and measure the time saved: it is the only criterion that really counts.
How much does Compilatio cost?
Pricing model: paid. A free plan is offered, usually limited in volume or features.
The first paid plan costs €4.99 one-off payment (Studium: 20 credits for 5,000 words; credits usable for six months), according to the pricing page, checked on October 24, 2026.

Data and privacy
According to its privacy policy, data is processed in the European Union.
Hosting in the European Union makes GDPR compliance easier, without exempting you from reading the terms of use.
No export feature is documented: keep a copy of your content elsewhere.
Three habits apply to every AI tool:
- turn off the use of your content for training if the option exists
- use a work account separate from your personal account
- review everything the tool produces before publishing or sending it

Compilatio runs on: web browser and API.
Interface languages: French, English, and Italian.
A public API lets you call it from your own programs or an automation tool, and plug it into an AI agent.
