Unvibe sits on top of a developer's existing workflow and explains code the moment it's selected, whether that's in Cursor, VS Code, GitHub, Claude, or a browser tab. Instead of switching to a chat window to ask what a block of code does, the explanation shows up in place, with adjustable depth depending on how much detail is needed. It also builds a personal history of what's been explained, turning ad-hoc lookups into something closer to a running knowledge base. The tool is in private beta and pre-revenue, with early testers currently validating retention and willingness to pay.
Autism Test Free brings together several established autism screening questionnaires, including the AQ, RAADS-14, ASSQ, CAST, ITC, and Q-Chat, in one accessible online format. Each assessment walks through structured questions and returns AI-assisted insights to help make sense of the results, alongside educational material on neurodiversity. The site is built for self-exploration, not diagnosis, and is explicit that it doesn't replace an evaluation by a healthcare professional.
