Soffi for product managers

Prototype on your real product in real time

Soffi runs a live version of your app in the browser. Build from a PRD or ticket, edit live screens, share a review link, and ship it as a pull request your engineers review. This afternoon, not next sprint.

What changes for you

Every handoff loses something, and someone rebuilds the prototype from scratch anyway.

The prototype starts from scratch. The product doesn't. Current tools just add another handoff and more confusion.

What product managers do with Soffi

  1. 01

    Turn a PRD or ticket into a live prototype

    Attach the PRD, start from a ticket, or just describe it. Soffi already has your screens, components and tokens, so it builds on the real thing instead of guessing at it.

  2. 02

    Edit existing screens without design queues

    Change the copy, the spacing, a button, a variant on a live screen, and ship it as a PR for review. You're using your code and don't need to re-upload context into a prompt every time.

  3. 03

    Test with customers early

    Open a workspace per flow, build multiple versions, and put them in front of your team or customers in the same week. Comments and video land on your app, not a dummy prototype.

  4. 04

    Give feedback and get it on the product itself

    Share a review link anyone can open. Comment on any component, record a video walkthrough, keep every thread in one place, and turn any comment into a change on the spot.

What you get

  • Plan mode

    Attach a PRD, pull a ticket, or say it out loud. Soffi builds the plan for you to approve.

  • Product context

    Your screens, components and tokens from your repo. Kept current. Nothing to re-upload.

  • Live workspaces

    Your product running in the browser, one click. No local setup, nothing to maintain.

  • Visual editing

    Click any element and change the copy, the spacing, a button, a variant. Undo works.

  • Review links

    A link on the running product, comment-only. No seat, no install, no login.

  • Comments and video

    Threads that sit on the component they're about, plus video walkthroughs.

  • Multiplayer

    More than one person in the same running product at once, every change attributed.

  • One-click pull requests

    A pull request with a summary and visual diffs into your existing eng review processes.

Your PRDs and specs
Attach a doc and build from it.
Figma
Bring files in as context.
Linear, Jira, issue trackers
Build from a ticket, push the PR.
Your design system
Read from your codebase, so it matches production.
Your knowledge base
Architecture, standards, patterns and design system, kept current and editable.
Your engineers' IDE
Claude Code, Cursor, Codex. Same branch, same pull request.

Common questions

01Isn't this another tool for my team to learn?

It's additive, not a process change. Start with one project and one squad. Your engineers keep their agents and review, work stays tracked as is, and designers keep their design tools.

02Do I need to know how to code?

No. Click an element and edit it, or describe what you want. Some PMs go deep on coding agents and get real results, but learning to code shouldn't be the blocker to building in product.

03Does Soffi push code by itself?

No. Soffi works in an isolated environment with no access to production, and nothing leaves it unless you open a pull request. Your engineers review and merge, exactly as today.

04Can I share this with a team member, exec, or customer?

Yes. Send a review link with comment-only access: no seat, no install, no account. They comment, record video, and reply in threads pinned to the components themselves.

05What happens if we don't ship the prototype?

Nothing to clean up. Workspaces rebuild from main and tear down when the work merges, so there's no stale environment and no orphaned branch.

06Where does the design system in my prototype come from?

Your codebase, so it's what's actually in production. That's why what you approve is what ships. Deprecate a token and Soffi stops offering it, even if someone prompts for it.
