FlowSnap vs Storyflow

FlowSnap turns app screenshots into sitemaps and user-flow diagrams for product managers, UX designers, and indie developers. Its infinite canvas supports panning, pinch zoom from 10% to 200%, color-tagged cards, and text annotations. A project can import up to 50 screenshots from a photo library or Google Drive. Users can connect cards with solid or dashed lines, customize connection colors, and label transitions. Optional AI tools analyze screenshots, suggest connections, and generate a Markdown sitemap summary; they require the user's Claude API key and send screenshots to Anthropic's Claude API. Projects are stored locally and can optionally sync to a FlowSnap folder in Google Drive, while the listing says FlowSnap does not store project data. Exports include PNG, PDF, SVG, JSON, and Markdown. The free plan allows three projects and adds a watermark to PNG exports. FlowSnap Pro costs $2.99 a month or $19.99, paid once, with unlimited projects, PDF export, watermark-free PNG, SVG, and priority AI features. Supported platforms are Android, iOS, and macOS.

Storyflow is a browser-based, low-fidelity wireframing tool for planning sitemaps, user flows and layout blocks on an infinite canvas. Users can describe a site or app and have AI arrange pages, screen flows and rough layout blocks. Screenshots, PDFs, reference links and video stills from YouTube or Vimeo can be added as references. AI can use the active board plus up to three Tactics, five documents and three boards as context. Storyflow includes templates, real-time collaboration, view-only sharing and exports in PNG, SVG or PDF. Approved structures can be taken into Figma. It is intentionally limited to ideation and low-fidelity wireframes: there are no component or UI libraries and no clickable prototypes. The browser product requires no installation. Storyflow says projects are private by default, data is encrypted in transit and at rest, and customer content is not used to train AI models. Plans include Free at free, Plus at $9.99 a month, Pro at $19 a month and Max at $49 a month.
