HOW ECHO BUILDS
Echo isn't just a chatbot.
It is a software team in a box.
Watch how a one-sentence brief transforms into verified, runnable software through coordinated multi-agent execution.

VERIFICATION ENGINE
Proof, not promises.
Most AI code generators output disjointed snippets and leave you to debug broken dependencies. Echo operates as an autonomous engineering pipeline that validates every commit in a sandboxed browser container before you ever touch the preview.

WHAT YOU CAN BUILD
Built for products that
generate real revenue.
Whether you are launching your first SaaS, building custom portals for high-ticket clients, or automating operational workflows, Echo gives you production-grade software foundations.
From idea to working product
Describe the commercial outcome. Echo turns it into a functional, runnable web application, not a static mockup.
Coordinated specialist agents
Specialist agents plan architecture, write UI components, and generate backend routes concurrently with zero merge conflicts.
Browser-verified preview sandboxes
Every build is tested in an isolated browser runtime before reaching your preview, catching errors before you do.

FAQ
Answers before your first prompt.
Everything you need to know about how Echo builds, verifies, and delivers working software.
What can Echo build?+
Echo creates modern, full-stack web applications: SaaS dashboards, custom client portals, internal operations tools, e-commerce storefronts, and interactive business software using React, Next.js, and TypeScript.
Do I need to know how to code?+
No. You can build entire products simply by describing outcomes, user flows, and features in plain language. For developers, Echo gives complete visibility and control: inspect every file diff, customize prompt instructions, and edit or export standard source code anytime.
Who owns the code and intellectual property?+
You do. You retain 100% ownership of all source code, assets, and applications generated. There are no proprietary runtime dependencies or lock-ins. You can download a clean ZIP or push to GitHub and host wherever you choose (Vercel, AWS, Railway, etc.).
How is Echo different from chat-based AI tools?+
Chat tools generate isolated code snippets that you must manually copy, paste, wire up, and debug yourself. Echo is an autonomous product builder: it drafts the system architecture, coordinates specialized agents to write multi-file code in parallel, tests the build in a sandboxed browser, and delivers a working preview.
Can I bring my own AI keys (BYOK)?+
Yes. Echo supports Bring Your Own Key for OpenAI, Anthropic, Google Gemini, Groq, and OpenRouter. With BYOK, you pay exact wholesale provider rates with 0% token markup from Echo, backed by a flat $12/month platform fee.
Can I see what changed between builds?+
Yes. Echo tracks every modification, agent decision, and file diff in a legible shared activity trail. You can review the exact changes made before approving, test the live preview, and roll back or refine with follow-up instructions.
What will you
build first?
Start with the idea. Echo plans it, builds it, tests it, and turns it into a working product.
