Cedille Ai
Cedille AI is a French-language writing assistant that generates, summarizes, and rewrites text using a custom open-source model built in Switzerland.
Cedille earns its place as a French-first writing assistant: generation, summarization and rewriting in one web editor, backed by a 6B-parameter GPT-J-derived model that is open source and self-hostable, so you are never locked out of the engine you are paying for. That combination — a French-tuned model plus the ability to fine-tune it on your own corpus — is genuinely unusual, and the 10M+ texts counter suggests real French-language usage rather than a demo. The gaps are structural: only three text skills are documented, there is no image, voice or video capability, and programmatic access is described as part of the Customized offering rather than a standard feature.

Skip Cedille if you need English-first output, image/voice/video generation, or a browsable integration marketplace — it is a French text tool with three documented skills.
Generation-based plans mean every prompt, summary and rewrite draws from the same monthly allowance, so heavy rewriting months eat the quota you budgeted for drafting.
Cedille's published subscription line at 9€/mo, 39€/mo and 139€/mo steps up with generation volume, so it fits solo French writers and small content teams rather than enterprise procurement. If you only need occasional French text, the free testing entry point covers you; if you need English plus French from one tool, general-purpose assistants cover more ground per euro.

The site reports more than 10 million texts generated by its community, and the public interface ships in English, French and German. It fits French-speaking writers, marketers, journalists and researchers who want fluent French output without wiring up a per-token API, and teams who want to experiment with a French model they can download and own.

Models under the hood
as of 2026-11-09
Limitations
- Cedille is built for French text, so non-French tasks sit outside its strength.
- Public pages document three skills — generation, summarization, rewriting — and no multimodal capability: no images, voice or video.
- The model is open source and fine-tunable, which is an advantage but shifts infrastructure work onto your team if you choose that route.
- The public site also positions API access alongside the Customized offering rather than as a standard feature, so verify programmatic access before you architect a pipeline around it.

GeneratedReal-world workflow fit

Outcome: A polished French deliverable in one session without leaving the browser or installing anything.
You feed a long transcript or press release into the summarizer, then use the generator to draft gazette-style copy from the key points for a quick-turn piece.
Outcome: Summarization cuts the reading time and the generator produces publishable French structure you edit rather than write from scratch.
You download the open-source GPT-J-derived model, fine-tune it on your internal French corpus, and self-host it so sensitive text never leaves your infrastructure.
Outcome: A French model tuned to your own domain, with no per-generation fees after the initial setup.
