Antidote: sovereignty score and 8 European alternatives

Antidote is a writing-assistance suite from Druide informatique with a grammar and spelling corrector, dictionaries and language guides for French and English. It integrates with the software in which you write and runs on computers, tablets and phones. Antidote 12 also offers a Reformulation mode, and Antidote Web corrects text in the browser. It is sold with a perpetual licence or as a subscription.

Druide informatique is headquartered in Montreal, Canada; no foreign parent is indicated. According to Druide, with a perpetual licence texts are processed only locally. With a subscription they also stay local, except in Reformulation mode, where texts are sent over the internet to Druide's servers; Druide states they are neither stored nor used to train AI models. The privacy policy describes transfers of personal data from the EU to Canada, relying on the European Commission's adequacy decision. Antidote is proprietary software with no documented self-hosting option.

Why digital sovereignty matters with Antidote

Antidote is headquartered in CA, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Antidote hosts data outside the EU (OTHER). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Antidote is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Antidote together with your other vendors and gives a total score, a heatmap and the main risk drivers.
