Custom multi-agent harness
A native tool-calling loop built for code, not a generic chatbot. The agent plans, writes, verifies its own output, and repairs what it breaks.
Your project is one prompt away from a shareable MVP.
400+ models from leading labs
Not a mockup generator. Cogsynth builds the whole app, then verifies it, syntax, broken assets, missing content, and runtime errors are caught before you ever see the preview.
Designed to work on your phone as well as your desktop. No local setup, no terminal.
Every build is checked for undefined references, broken images, empty pages, and runtime errors, then repaired before you look at it.
Don't know what to type next? Contextual suggestions move you from idea to finished app.
Describe everything at once. No wizards, no 20-step forms, including long PRDs.
SaaS, stores, dashboards, blockchain dApps, portfolios, start polished, customize fast.
Auth, Postgres, Stripe checkout, and more, wired into the app instead of stubbed out.
Three steps. No coding required.
Brain-dump your idea in one prompt. Use as much or as little detail as you want.
Watch the app come to life right in the Cogsynth dashboard. Click suggestion chips to iterate. Cogsynth's suggestions are tailored to your project, so you can just approve what you like, and watch it build.
Export clean code as a ZIP, publish to a live share link, or keep building out your project.
Not a chat wrapper. A purpose-built system for turning intent into working software.
A native tool-calling loop built for code, not a generic chatbot. The agent plans, writes, verifies its own output, and repairs what it breaks.
Contextual next steps drawn from your actual project, so you are never staring at an empty prompt box.
120+ production scaffolds across SaaS, commerce, events, games, and Web3. A starting point, not a cage.
Auth, payments, database, and pipelines wired into the app automatically. Cogsynth builds with these additions in mind.
Your request becomes an explicit build plan and PRD you can read and edit, so you always have full control over the direction.
Canvas reads docs and notes and searches for complementary sources while it writes, so new code fits what is already there.
Generated apps come with real docs describing structure and behaviour, not a README placeholder. Cogsynth references and maintains them to reduce scope drift.
Self-improving suggestions that keep proposing the next step, so a project can grow without you driving every turn.
Works with frontier hosted models or fully open-weight ones. Bring your own keys, or start from a repo you already own.
