NeverSwipe - Your AI agent does the looking, so you never swipe — in SF

Launching in San Francisco first. Swiping asks you to judge a hundred strangers by a photo; neverswipe asks you nothing. You brief an AI agent once — who you are, who you hope to meet — and it does the looking, comparing and ruling-out. It only introduces you to someone in SF, close enough that coffee is a decision, not a flight — at most one a day, with a note on why. No profile to perform, no feed to scroll. Invite-only while we gather enough good people here. Not a match. An introduction.

OnePrompt - Can this be built with a prompt? Paste a URL, get a verdict

Paste any URL and get an honest answer to "can this be built with a prompt?" OnePrompt's agents read the real code and fingerprint the hidden backend most clones quietly skip — SDKs, APIs, auth, payments, CMS. You get one verdict: an EASY→HARD score, the effort in plain terms, prompt-count and cost estimates, and a one-line bottom line. No hype, just evidence. The full analysis adds live market demand, named competitors, monthly run cost, and an honest "worth cloning?" call. 3 free a day.
