In their own words
Marvel
Marvel is a design platform for creating wireframes, mockups, prototypes, and design specifications. From a browser, users can make website and app designs for different devices, then share interactive prototypes that demonstrate intended interactions without coding. Its Handoff tool generates downloadable assets and CSS, Swift, and Android XML code that stays synchronized with design changes.
Teams can organize projects in folders, create teams, and leave feedback through comments and annotations. Marvel lists integrations such as Sketch, Jira, Confluence, Dropbox Paper, and Microsoft Teams, as well as a GraphQL API for project data and design activity. Its mobile apps let users create, play, and share prototypes, with offline viewing and Sketch syncing. The free plan allows one user and one project; moving down to the free plan makes other projects inactive. Pro costs $12 a month, billed yearly, and a seven-day trial is listed. Marvel was founded in 2013 and is headquartered in London.
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.
