In their own words
Overflow
Overflow lets users create, present, share, and get feedback on interactive user flow diagrams. It syncs designs from Figma, Sketch, Adobe XD, and Adobe Photoshop. Diagrams can include customizable connectors, styles, device skins, hotspots, shapes, text, and multiple boards. Users can present playable flows, self-guided Stories, and rapid prototypes. Cloud publications can be shared by link, embedded, protected with a passphrase, exported as PDF or PNG, or printed. Collaboration includes personal and team folders, editor invitations, comments, mentions, and notifications, with integrations for Confluence, Jira, and Trello. Overflow is available on macOS, Windows, and the web. Its 14-day trial requires no credit card and gives desktop-app and Cloud-sharing access without limitations. After the trial, that access ends; data remains hosted for 60 days and is then deleted if no subscription is activated. Pro costs €19.95 per user/month, billed monthly, and includes 1GB cloud storage per user, Cloud sharing, folders, and comments.
Storyflow
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.
