"This has become the 'second brain' for our team. I loaded all our SOPs and project histories, and now I get instant, accurate answers with citations. It's saved me countless hours."

Sarah P., Executive Assistant · June 2026

"The setup was incredibly fast. We went from a messy collection of Google Docs to a fully functional internal help bot in an afternoon. The no-code interface is a huge win for us."

David L., Operations Manager · May 2026

"It works well, but the accuracy is only as good as the documents you feed it. We had to spend a lot of time cleaning up our knowledge base first. Also, the entry-level plan is quite limited."

Maria K., Chief of Staff · June 2026

"The security features were the deciding factor for us. Knowing our confidential data is protected by SOC 2 compliance and isn't used for training gives my executive peace of mind."
