Product Engineering Teams

Ship fast with AI. Stay in control.

A living spec for your whole product. Always up to date, shared across your whole team, across every agent.

codemix captures what you actually mean. It understands your business, your user flows, the concepts, and the constraints. It builds a living source of truth that humans and AI can trust.

  1. Capture Intent
    • Conversations and decisions become structured product context.
  2. Steer Agents
    • Coding agents stay aligned with what you decided.
  3. Ship What You Meant
    • Every code change verified against the spec.

Understanding is everything.

Coding agents are already good at code. That was never the hard part. The hard part is knowing what the product is meant to do, where the edge cases are, and which old decisions still matter.

A repo alone can't tell them that. Neither can a folder full of stale markdown specs or abandoned Notion docs. Those files look authoritative right up until they send the agent in the wrong direction.

codemix keeps the intent alive. It turns conversations, specs, decisions, issues, and code into a product model that updates as the product changes. Agents stop guessing from archaeological fragments and start working from what the team actually means now.

Keep the human in control.

Vibe coded apps leave most decisions to the agent. You ask for the product, it makes hundreds of calls on your behalf, and whether you get what you meant is basically a lottery.

codemix surfaces the questions and decisions earlier. You decide how much detail you want to work at. Broad strokes in most places, precise behavior where it matters. That's gradual specification.

Trusted, but Verified.

Coding agents need something better than a prompt and a pile of files. codemix gives them the current source of truth while they write code: intent, constraints, decisions, edge cases.

Then it checks what they built against what was meant. If the code drifts, codemix flags it. If development uncovers a real decision, codemix updates the spec.

Stop paying the coordination tax.

Every product change starts with context scattered across half a dozen tools. The ticket says what to build. The Slack thread says why. The doc says what used to be true.

codemix pulls those fragments together and gives humans a place to settle the answer. Not a giant requirements doc. A current spec with the decisions, constraints, and edge cases that actually matter.

Two ways to build

  1. Use codemix yourself
    For teams with their own builders. Capture product intent, steer agents, and review work against the spec without changing how the team ships.

  2. Build with us
    For founders and teams who want us in the hot seat. We use codemix, our platform, and our delivery experience to ship high-quality software with you.
    Talk about the build

Ask product questions directly from your terminal.

The CLI gives coding agents and humans a fast path into your product context. Ask how behavior works, trace rules back to source material, and keep implementation moving without tab-switching.

$ codemix ask "Who can invite teammates and what are the constraints?"

Team invitations follow admin-only rules:

  • Only team admins can send invitations
  • Invites expire after 7 days
  • Existing users are added directly (no email sent)
  • Blocked domains → "Domain not allowed" error

Shipping, support, and product questions in one place

Onboarding starts with workspace setup, then either importing a project or using interview mode. Task generation stays off until project context is connected.

Typical flow: create a workspace → connect a repo or finish the interview → review the model → generate first tasks. If the repo isn't linked or the interview isn't complete, onboarding stays blocked.

Integrations

Connect coding agents, trackers, docs, and collaboration tools without changing how your team works. codemix becomes the shared context layer across the stack.
