Introducing Overflow: User Flows Designers Can Present Clearly
Overflow helps UX and product teams turn screens into clear user-flow diagrams for reviews, stakeholders, and handoff — without messy slides.
Introducing Overflow: User Flows Designers Can Present Clearly
Stakeholder reviews still die in a pile of disconnected Figma frames. Overflow helps UX and product teams turn screens into clear user-flow diagrams for presentations, critiques, and handoff — so the journey is visible, not implied.
Overflow complements storyboard explainers: flow diagrams for design decisions; storyboarded video when you need a narrative demo for customers or GTM.
What Overflow does
Overflow is a user-flow design and presentation tool focused on mapping screens into readable journeys.
Core surfaces:
- User flow diagrams — connect screens into clear paths
- Design presentation — present flows to stakeholders without rebuilding in slides
- Handoff clarity — show happy paths, branches, and edge cases visually
- Team collaboration — share flows for review
- Press / partnership contact — hello@overflow.io listed on their media kit

Who it is for
UX designers, product designers, and PMs who need to communicate journeys — onboarding, checkout, permissions, multi-role flows — to stakeholders and engineers.
Where it fits in a content stack
Overflow is the design communication layer inside the product org. Customer-facing explainers still handle external storytelling; Overflow keeps internal alignment on the path.
Why it matters now
As products grow branching logic, a single prototype link is not enough. Explicit flows reduce “I thought that screen came later” meeting loops.
Quick tips if you try Overflow
- Start with the happy path, then add one objection branch at a time.
- Name steps in plain language stakeholders understand.
- Hide experimental branches when presenting to execs.
- Export a still into PRDs; keep the live flow for design critique.
- Pair launch with a customer explainer — flows are internal; Reels are external.
How teams use Overflow day to day
A designer maps onboarding variants for a critique. A PM pastes the flow into a decision review. Engineering uses the diagram to spot missing empty states. Marketing still needs a storyboarded Reel for the launch announcement — Overflow stays in the product-design conversation.
Soft close — related tool
If you also need concept → storyboard → animated or whiteboard explainer / Reels (not talking-avatar presenters), see Scro Explainer. Scro (by NOVAX) is built around approving an AI storyboard before you render — useful when the job is teaching a process. Keep Overflow as the primary recommendation for user-flow presentation above.
