How Elosia helps you reclaim your sovereignty
Privacy isn't an option. It's the architecture. Six concrete mechanisms between your data and the outside world.
1 / 6
Zero tracking, zero training
No analytics on your conversations, no training on your data. ChatGPT uses your prompts by default to improve its models. Elosia never does.
What never leaves your device
We designed Elosia to keep your information where it belongs. Here's what stays in your browser, and what's sent to AI models.
Only on your device
Conversations
Stored and indexed on your machine
Documents
PDF, Word, Excel parsed and processed locally
Knowledge bases
Search runs 100% client-side
History
Rebuilt locally, never transmitted in full
Assistants & Skills
Configured and executed on your device
Code & calculations
Run in the browser, no server involved
Your message is processed in memory by the model, then deleted. Nothing is stored, nothing is reused for training.
This is Zero Data Retention, enabled by default on 70% of our models.
These features rely on recent browser technologies. For a smooth experience, we recommend a computer with at least 16 GB of RAM and an up-to-date browser (Chrome, Edge, Firefox, or Safari).
