Reviewer scorecard
“Perfect for prototyping. I described a dashboard and had a working app in 3 minutes. Not production-ready, but unbeatable for speed-to-demo.”
“At $500/mo it needs to replace at least 10 hours of developer time per month. In my testing, I spent more time reviewing and fixing its output than I saved. Not there yet.”
“Impressive demo, but the generated code is messy and you'll rewrite most of it. If you can't code, you can't fix what it breaks. Know what you're getting into.”
“The marketing writes checks the product can't cash. 'Autonomous software engineer' implies reliability that doesn't exist. It's a talented intern that needs constant supervision.”
“As a creator who needs quick landing pages and MVPs, this is a game-changer. I built a waitlist page with email capture in under 5 minutes.”
“Devin is early but directionally correct. The autonomous agent approach will win eventually. Cognition has the best shot at getting there first. Invest in the future, not the present.”
