Perplexity Computer adds REA skill that rebuilds apps without their source code Other

Perplexity has added REA (Reverse Engineer Anything) as a skill in its Computer agent. You ask Computer to reverse-engineer an app, and it studies how the app works without the source code, then builds a working version. Perplexity announced it on X on October 16, 2026.

Free credits

Tasks that use the /reverse-engineer command are free through October 31, up to 10,000 credits per user. CEO Aravind Srinivas called it a "bootstrapping credit balance" for anyone who wants to reverse-engineer an app of their choice.

Five demo apps

Perplexity showed five web apps that Computer built with REA. They are live for a limited time.

What REA is

REA is an open-source MCP server by developer morluto, under the MIT license. It lets an AI agent inspect a target and return findings with evidence.

• Native binaries: pseudocode, assembly, strings, symbols, calls and references, using Hopper, Ghidra or IDA.
• JavaScript and Electron apps: modules, imports, source maps, routes and IPC.
• Websites: page structure, scripts, network traffic and screenshots, through a Chrome-family browser.
• Other targets: .NET, Android APKs, WASM, firmware, packet captures and more.
• It can also run a target and record its runtime behavior.

Outside Perplexity, you can add REA to your own agent with npx rea-agents setup.
