Testimonials
"
Sen completely changed how our team works. We went from spending hours on boilerplate to focusing entirely on architecture and product decisions. The AI understands our codebase like a senior developer.
"Sen Desktop's dual modes are a game changer. I use Developer Mode for complex refactors and switch to Simple Mode when I just want to talk through an architecture decision. Time-travel snapshots alone save me 2 hours a week."
"Sento handles my entire morning routine autonomously — briefing summaries, meeting prep, follow-up emails. It's like having an executive assistant that never sleeps and costs virtually nothing."
