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.
Synclet
Synclet is a web service that turns natural-language product descriptions into visual prototypes. Users refine screens, flows, and design updates through chat while Synclet builds a structured specification covering users, surfaces, screens, and their relationships. Generated designs can span web, mobile, and tablet experiences, including role-based screen variations. Prototypes are shareable through public links, and the specification can be downloaded in Markdown for AI coding tools such as Cursor, Replit, Lovable, and Claude Code. Some features work without an account; full access requires Google sign-in. The Free plan costs nothing and includes one project, seven screens per month, prototype generation, chat refinement, sharing, and export. Founding Member also costs nothing and includes five projects, 100 screens per month, sharing with anyone, export, and priority support. Existing screens remain accessible after reaching a limit. Synclet describes HTTPS/TLS encryption, secure authentication, assessments, and access controls.
