Perplexity’s Computer added a new skill called REA (Reverse Engineer Anything), developed by morluto, that inspects how an app works without access to its source code and then assembles a working recreation. Users invoke it with the /reverse-engineer command; Perplexity is offering tasks that use this skill free through October 31, with a cap of 10,000 credits per user. The capability is presented as an end-to-end tool embedded in Computer: point it at an app, it analyzes behavior and interfaces, and it generates a runnable implementation and demo.
Five short-term demos showcase what REA can produce: a Figma-like UI editor with layers, auto-layout, sign-in, cross-device sync, and multiplayer editing; a LibreOffice Calc-style spreadsheet supporting cell editing, formulas, and live charts; a Photopea-like image editor with layers, masks, color adjustments, and editable text; a Harvey-like contract review tool that searches documents, compares versions, flags clauses against rules and supplies source citations; and an Audacity-style audio editor for trimming, mixing, fades, and WAV export. Each demo is available to try on Perplexity’s demo subdomains for a limited time.
