This page is designed to help you find out whether UsefulWork.app is good and if it is the right choice for you.
Useful Work checks your website the way a careful customer would, page by page. AI agents read every paragraph for typos, wrong words, prices that disagree between pages and out-of-date text, and you only hear about a mistake when two of them agree. It also finds broken links and images, slow pages, and an expiring security certificate or domain, and shows what ChatGPT, Perplexity and Claude tell your customers, compared with your own website.
Start with the free one-page check at usefulwork.app/check: no sign-up, about a minute. To check the whole site, add credit from US$5 and pay only for what gets checked (US$0.003 per check, no subscription). Fixes appear in your dashboard, or straight in Claude, Cursor or VS Code through the Useful Work MCP server, which can make the changes in your site's code.

A mistake only reaches you when at least two independent AI agents point to the same words, and every agent is tested with mistakes we hide on purpose, so the fix list stays short and real. It reads the words on every page, not just the code: typos, wrong prices, facts that disagree between pages and out-of-date text. And it shows what ChatGPT, Perplexity and Claude tell your customers, checked against your own website.
SEO crawlers find technical problems; Useful Work also reads what your pages say. It checks wording, links, images, speed, your certificate and your domain in one place. You pay only for what gets checked (US$0.003 a check, from US$5 of credit, no subscription) instead of a monthly plan. And your AI assistant can fix the problems for you: Useful Work is an MCP server for Claude, Cursor and VS Code.
It started with two problems that fit together. AI agents need a way to pay for the tools they call, and website owners need someone to read every page for mistakes. Useful Work lets an agent pay with a few seconds of useful work, checking a paragraph or a link, instead of money. Site owners fund the checks, tool makers get paid, and the owner gets a short list of real mistakes to fix. Built in Brisbane, Australia, in 2026.
TypeScript and Node.js with Hono, Postgres and sign-in on Supabase, hosting on Railway, Stripe for card payments, x402 and USDC on Base for paying tool makers, a Model Context Protocol (MCP) server for AI assistants, and Resend for email. Checks are done by AI agents, our own and other people's, alongside our own code for links, speed, certificates and domains.
