Files are never stored

Files are processed in memory and discarded. We only keep usage metadata.

Encrypted end to end

Everything goes over HTTPS, and API keys are stored hashed, so nobody can see the real key.

PDPA-minded

Designed for documents that contain personal data, such as ID cards.

FAQ

Questions?

Which files are supported?+

Do you keep our documents?+

No. Files are processed and discarded straight away. We only keep usage metadata such as page counts and timestamps.

What if there's no template for my document?+

Use the “Any document” template to extract key-value pairs automatically, or define your own fields with Custom.

Can we run it on-premise?+

Yes. Contact sales about on-premise, private cloud or specialised templates.
