About Echo
Echo turns a plain-English product brief into a planned, web application with preview and verification tools. It generates a React, Next.js and TypeScript codebase you can review, preview, export and keep.
01 / The short answer
Echo is an autonomous AI software-building platform for web applications. You describe the product in plain language. Echo turns that brief into a technical plan, coordinates specialist agents to implement it, verifies the result in a browser sandbox and hands you the resulting project.
A general-purpose chatbot can answer a programming question or produce an isolated component. Echo is organised around a larger unit of work: an application with routes, a data model, server logic, screens and states that have to agree with one another.
Echo is an autonomous AI software builder that converts a natural-language brief into planned, generated and reviewed web software, with source code the user can export and run.
02 / Who it is for
Echo is a tool for building software, not a replacement for the judgement required to run it safely in production.
03 / What a build looks like
Say who the product is for, what it must do and what data it holds. A schema, existing spec or voice brief can be part of the input.
Echo writes the route graph, data model and API contracts before it edits files. You can change the direction while changing it is still cheap.
Specialist agents implement the interface, state, server routes and quality checks from the same plan and the same shared context.
The application runs in a sandbox. Echo visits routes, checks that they render and sends failures back through a repair pass.
Inspect the preview, file diffs and activity trail, then export the project as a ZIP or sync it to your own repository.
04 / Code, keys and pricing
Echo generates React, Next.js and TypeScript. Export the project as a ZIP or sync it to GitHub, GitLab, Bitbucket or Gitea. There is no proprietary runtime in the middle.
Bring OpenAI, Anthropic, Gemini, Groq or OpenRouter keys and pay the provider directly, with no token markup from Echo. Or use managed Echo credits and managed compute on the managed plans listed on the pricing page.
Start with the free BYOK trial. Paid plans add managed infrastructure or included credits, and Enterprise is a custom agreement. Current availability and prices live on the pricing page.
05 / Common questions
These are the questions that decide whether Echo is the right tool for a project.
Echo is an autonomous AI software builder that turns a plain-English product brief into a planned web application with preview and verification tools and gives you the source code behind it.
Yes. Echo generates a React, Next.js and TypeScript project. You can export it as a ZIP or sync it with GitHub, GitLab, Bitbucket or Gitea, then run and host it without a proprietary Echo runtime.
Yes. Echo supports bring-your-own-key access for OpenAI, Anthropic, Google Gemini, Groq and OpenRouter. On the BYOK path you pay the provider directly and Echo adds no token markup. Managed Echo credits, where available, remove the need to manage provider accounts; the pricing page lists current plan availability.
A chat tool usually returns code fragments that you assemble yourself. Echo plans the architecture, writes multiple files in parallel, runs the result in a browser sandbox and hands over a project you can preview, export and keep.
After a build, Echo opens the application in a sandboxed browser, visits its routes and checks that they render. Failed checks feed into a repair pass. The build activity trail and file diffs stay visible so you can review what changed.
Echo builds web applications, not native mobile apps. AI-generated code can contain mistakes, and integrations, security, payments and regulated data still need human review. One prompt does not guarantee a production-ready product.
Echo starts with a free trial that uses your own AI provider keys, then continues on a paid plan. Paid plans add managed build infrastructure or managed Echo credits, and Enterprise is a custom agreement. The pricing page is the source of truth for current availability and prices.
Create an account, describe the product you want, then choose Plan to review the architecture first or Build to run the full pipeline. The Echo guides walk through a first web app and a SaaS MVP step by step.
The Guides hub contains Echo’s published walkthroughs. The Contact page lists the official support email, and the footer of every public page links to the policy pages and the official X account.
Official product pages: AI App Builder, Features, Use Cases and Pricing. Published walkthroughs live in the Guides hub, and support details are on the Contact page.
The free trial uses your own AI provider keys and includes the workspace, previews and source-code export. Read the plan, inspect the build, then decide what ships.
