What is Rezonant?

Rezonant helps product builders go from a rough idea to engineering-ready work, ready to send to your team or coding agents. It's a workspace to bring all your product context into one place, so your team can collaborate and align on one source of truth.

Think of it as a thinking partner that knows your product inside-out. It connects to your codebase, your docs and syncs with your other tools, so the ideas that you shape are grounded in how your product actually works.

What you can do with Rezonant​

  • Turn ideas into tasks. Describe a feature or problem and Rezonant helps you break it into well-scoped, context-rich tasks.
  • Write product documents. Draft PRDs, specs, and briefs in a collaborative editor that your coding agent can read and build from.
  • Yap to spec. Capture ideas for new features with the Rezonant Alter Chrome extension, just by talking and pointing to anything on your screen. Rezonant will create a spec that's grounded in your product context for you to review, edit and ship.
  • Handoff to your coding agent or devs. Push finished tasks directly to your coding agent, Jira or Linear, with the relevant context already attached.
  • Run the coding agent. Hand a shaped task to Rezonant's coding agent to explore the codebase, draft an implementation, and open a PR.

Who Rezonant is for​

Rezonant is for people building software - solo, with a team, or across a large organisation. It's built for anyone who wants to think through ideas before moving to code, using an AI model that understands their specific product. By connecting to your codebase, docs, and tools, it ensures what you hand off to engineers or coding agents is properly shaped and ready to build, not just ready to read.
