Briefs describe features, not intent
You know what to design. You often do not know why it should work that way.
Proposals
Review what you're about to build before it's built
A proposal describes the change in terms of product behaviour: what users will experience, what's in scope, and what isn't. Codemix writes it after understanding your codebase, so it's grounded in reality rather than assumption.
The brief problem
Good UX requires more context than most briefs provide.
The best UX work comes from understanding the product: the user stories, use cases, decisions and reasons. That context usually lives in conversations and memory, not in the brief.
Without that context, designers solve the feature as described, not the problem underneath it. The output looks right. The experience falls short.
The why behind existing patterns stays invisible
You can see the pattern. You cannot see the reason. That is how deliberate choices get accidentally undone.
Use cases that surface too late
The brief covers the primary user. The product has five user types, permissions and journeys. Naturally this appears after the design is done.
The experience you shipped is not the one you designed
The screens matched. The user goal and rationale did not. That is not a visual bug, but users still feel it.
Understand the product before the first frame
Design from the story, not just the brief
A brief tells you what to design. It often leaves out who the product is really for and why the system works this way.
Codemix gives you the product's concepts, flows and decisions before wireframes start. New work builds on the product instead of accidentally fighting it.
Project overview
See everything in flight, at a glance
The overview surfaces every active proposal, running task, and recent conversation in one place — no status updates required. Codemix keeps it current as work progresses, so anyone on the team can see what's happening and where things stand.
Ask the why questions mid-design
Understand the reasoning without waiting for a sync
Intent questions show up mid-design. Why this flow? Which users? Why this constraint?
Codemix lets you query the product model directly. You get the reasoning while the comp is still cheap to change.
Conversations
Work through the problem together
Codemix grounds every reply in how your product actually works — not generic advice, but specific to your codebase and domain. When you're ready, it drafts a proposal that captures the intent in a form the rest of the team can review and challenge.
Design for the full range of use cases
See the whole picture before the design is done
The brief describes the primary user. The product usually serves more than one.
Codemix surfaces user types, use cases and contextual variations before the design locks in. Better as design input than late correction.
Task plan
A complete task plan, ready to execute
Once a proposal is approved, codemix breaks it into parallelisable tasks and executes them autonomously. The task plan keeps every behavioural commitment visible while the build is underway.
Ship the experience you meant
Keep your intent intact from first frame to final build
The gap between design and shipped product is often not visual. It is context.
Codemix keeps the user story and design intent with the work. Engineering gets more than a Figma interpretation exercise.

How it works
How Codemix carries context through the full lifecycle
Most product drift happens in the handoffs: from discussion to spec, spec to task, task to code, and code back to the roadmap. Codemix keeps those handoffs explicit.
- 00start
Start with a conversation or from code
Chat with codemix if you're still at the idea stage, or import your existing codebase.
A product baseline
Start with an interview
Talk through the product in plain English. Codemix turns the important parts into something the team can inspect, question, and build from.
Start with the repo
Connect the existing codebase. Codemix reads how the system behaves today, including the bits nobody remembered to write down.
- 01model
model the product
Codemix builds a working model of the product: the concepts, screens, actions, rules, edge cases, and decisions that explain how it is meant to behave.
A model the team can ask about
- 02proposal
shape the change
Before implementation starts, you can ask questions, edit the spec, and turn a rough idea into a concrete proposal for what should change.
A proposal people can review
- 03tasks
write the tasks
Once the proposal is approved, Codemix turns it into implementation work. Send it to Linear or Jira, hand it to a coding agent, or let humans and agents split it up.
Tasks with the context attached
- 04answers
answer questions mid-build
Implementation always uncovers questions. Codemix gives engineers and coding agents answers from the product model, so they don't have to guess from a ticket title or a nearby file.
Product answers during the build
- 05review
review what changed
Codemix reviews the code against the product decision, not just against style, tests, or neighbouring code. That's where a lot of agent mistakes hide.
Review that checks intent
- 06release
ship, then update the spec
Shipping often reveals details nobody saw at planning time. Codemix helps fold those decisions back into the spec, so the source of truth doesn't go stale the moment the PR lands.
Code and spec brought back together
- 07feedback
bring the context forward
Bring in bugs, customer feedback, support notes, and product signals. The next proposal starts with the context you already built, instead of another round of archaeology.
