Refactual — AI Code Assistant

Refactual is a full-stack AI engineer in your pocket. Describe what you want built and it builds it — then helps you fix, refactor and understand the code you already have.

BUILD SOMETHING
Ask for a website, a landing page, a dashboard, an internal tool, a form, a calculator, a small game or a prototype, and Refactual writes it and ships a working preview link you can open and use — not just a block of code to copy. Keep chatting to change it: another section, different colours, make it responsive, add a sign-in. When you are happy with it, download the whole project as a zip straight from the app.

SCRIPTS AND GAME CODE
Paste a script that is throwing an error and get it explained and fixed. Roblox and Lua, Python, JavaScript, TypeScript, HTML and CSS, SQL, shell — bring the language you actually use. Refactual reads what you pasted, tells you what is wrong, and hands back a working version you can drop straight back in.

NOTHING TO INSTALL
There is no toolchain to set up and no laptop required. Open the app, describe the thing, and read the result. It is the same assistant whether you are at a desk or on a bus.

FIX AND UNDERSTAND CODE YOU ALREADY HAVE
• Explain this file, this function, or this error message
• Review for bugs, security holes, performance traps and accessibility gaps
• Add tests, tidy the structure, make it readable
• Ask follow-up questions until it actually makes sense

MODERNIZE A REAL CODEBASE
The heavy machinery is still here. Connect a repository from GitHub, GitLab or Bitbucket and read the modernization report on your phone: a health score, the hotspots worth your attention, estimated ROI, and a step-by-step remediation plan. Port legacy code forward — COBOL to C#, jQuery to React, Java 7 to 21 — and run the fixes as jobs.

IN THE APP
• Chat — answers stream in live, pick the model that fits the job, switch on web search when you need current information
• Attach — photos, screenshots, PDFs and documents, then ask about what is in them
• Repos — your reports, refactors and repository connections
• Parser — turn PDFs and documents into structured data
• Monitor — alerts when a page or repository you watch changes
• Share — send a reply as a link, or post it straight to Slack
• Account — your plan and your shared credit balance at a glance

WHO IT IS FOR
People building their first website or their tenth. Game scripters. Students working out why something will not run. Founders putting a prototype in front of someone this week. Teams carrying a large, old codebase forward. You do not need to be a professional developer to get something working out of it — and if you are one, it will not waste your time.

Everything syncs with refactual.com, so you can start something on your phone and finish it on a laptop, or the other way round.

Free to download, with an optional subscription and in-app purchases. Your workspace syncs across phone, tablet and the web.
