Meet Vertigo.

The assistant that runs on your phone and your computer. It checks before it answers, and what you say stays with you.

Chat with VertigoDownload the app
Vertigo on a phone: an answer about Marie Curie, and its receipt: source checked on Wikipedia, 3.2 seconds on the device

Answers you can check

Every answer comes with a receipt: the source it read, the calculation it made, or the rule it followed. Share the receipt, and anyone can check it again.

Your documents stay yours

Ask about a contract, a course or a handbook. Vertigo quotes the passage it used. Remove the document, and it is forgotten.
