Features

Everything you need to demo complex workflows

From URL to polished walkthrough — with full control at every step. Built for sales engineers, product marketers, and customer success teams who need more than a screen recording.

Multi-persona orchestration

Define presenters and operators with distinct credentials, voices, and browser sessions. CastFlow intercuts between them to show real collaboration workflows.

Natural language flow builder

Describe your demo in plain English. CastFlow breaks it into discrete steps, assigns personas, and presents the flow for review before execution.

Step-by-step refinement

Every step comes with a screenshot and editable action. Refine selectors, split or merge steps, and fix failures with human-in-the-loop guidance.

Live browser execution

CastFlow navigates your app with Playwright, captures full-page screenshots, and handles dynamic UIs — not static HTML clones.

Per-persona narration

Generate voiceover transcripts tied to each step. Each persona gets their own voice, creating demos that feel like a conversation, not a monologue.

Phase 2

GitHub-aware navigation

Connect your repo to bootstrap flows from existing UI tests and routing code — reducing the cold-start problem of defining every step manually.

How it works

From URL to demo in five steps

No manual screen recording. No static HTML clones. Just describe what you want to show and refine the result.

Enter your app URL

CastFlow loads your application, scans its structure, and discovers reachable pages and navigation patterns.

Define your personas

Create presenters and operators with credentials, voice profiles, and browser settings. Each gets an isolated session.

Describe the demo flow

Write what should happen in plain English. CastFlow generates a step-by-step plan with persona assignments for your review.

Execute & refine

CastFlow runs each step, captures screenshots, and flags anything that needs help. Refine actions and narration until it's perfect.

Share your demo

Publish as an interactive walkthrough, export video, or embed on your site. One demo, multiple formats.

Why CastFlow

Built for workflows no other demo tool can show

Approval chains, admin portals, marketplace flows, collaboration tools — if your product involves more than one user, you need more than one browser session.

The gap in the market

Storylane, Navattic, and Supademo excel at single-session walkthroughs. CastFlow is the only platform that orchestrates multiple personas with distinct credentials to demo real multi-user collaboration.

Sales teams using product demos close 30% more deals

Yet many teams spend 2–12 hours on a single personalized demo. CastFlow automates the heavy lifting while keeping you in control.
