In their own words
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.
Zeplin Flows
Zeplin Flows helps teams map user journeys and make design intent clearer across screens. Diagrams use labels, shapes, and connectors that reposition when screens are added or removed. Teams can group screens and flows into Flow Groups and Boards, then share them through quick links. Shapes can represent actions, decisions, and branches, helping product, QA, and Support teams identify gaps and add use cases. Flows are included across plans, while Flow Boards are available on Advanced and Enterprise. The Free plan is free and includes one project, 100 screens, unlimited members, and no Flow Boards. Advanced costs $12 a month, billed annually. Zeplin offers Mac and Windows desktop apps and a web app that works on Windows, macOS, and Linux; the web app does not support uploading designs. Listed integrations include Figma, Sketch, Jira, Storybook, VS Code, Azure DevOps, Slack, Microsoft Teams, an API, and webhooks. Developer inspect view, design tokens, asset handoff, code snippets, and version history are listed.
