GDPR-Compliant Options
What to Expect When Switching
Switching from OpenAI API to a European alternative is typically straightforward. Under GDPR Article 20, you have the right to data portability — OpenAI API must allow you to export your data in a machine-readable format. Most European providers offer import tools or migration guides to help you transfer your data with minimal downtime.
For small teams, migration can often be completed in a single day. Larger organisations should plan for a phased rollout over one to four weeks, starting with a pilot group to identify any workflow adjustments. The most common challenge is not the data migration itself, but updating integrations and retraining team members on the new interface.
Mistral AI and DeepL offer a free tier, so you can evaluate the product with real data before committing to a full migration.
