Wynter AI is a suite of tools for AI builders, including sales funnels, web apps, micro tools, feature development, video sales letters, and a task system. Its core idea is that every tool provides a real blueprint for your AI rather than a blank prompt, letting development start from a plan instead of guesswork.
Main capabilities and how to use them:
- BuildThisWebApp (buildthiswebapp.com): Turns a one-sentence idea into the brief an AI coder actually needs, including research, a PRD, design direction, models, and copyable build prompts; you can also directly use plans others have already completed.
- BuildThisFunnel (buildthisfunnel.com): Choose a funnel type, give the AI builder that understands your app a link, and get patterns, edge cases, and a build checklist.
- BuildThisTool (buildthistool.com): Spec out micro tools such as calculators, quizzes, or scorecards down to the edge cases, ready to hand directly to a coding agent.
- DoTheseTasks (dothesetasks.com): Mark up screenshots and publish them as private URLs; your agent will work through the tasks one by one, with no project manager needed.
- AddThisFeature (addthisfeature.com): Give the agent a link and build features into an existing app, adapted to your stack, components, and design system.
Account and billing: No password setup is required; a login link is sent by email. One Wynter.ai account can open all apps. The free version includes the full catalog of each app, readable and copyable; the Pro version (subscription plan) unlocks advanced features across all apps, including site scanning (writing five recommendations for your offer), custom blueprints for your stack, collections, and saved work, and you can cancel at any time and keep your work. AI credits are metered and purchased separately, shared across all apps, and never expire: 1,500 credits for $12, 5,000 credits for $35. Free and paid accounts purchase the same credit packages.
Free open-source tools (not part of the suite, run on your local machine, source code is readable):
- Nabu: A local always-on operations agent that manages tasks, queues, approvals, and schedules, then hands the actual work to Codex. Data is stored in ~/.nabu, and it never opens a port to the internet. Install command: curl -fsSL https://nabu.sh/install.sh | bash
- Cats with jobs: Chat with agents that build real tools (compiled Go services rather than prompts); after you assign tasks, they execute, hand work off to each other, and keep the dashboard refreshed around the clock, with zero token consumption.
- Workbench: Scans all projects on your hard drive, runs the projects you trust, captures real screenshots for each project, and places them in a single library.
Use cases: developers, founders, and marketers who use AI to build web apps, sales funnels, micro tools, or add features to existing apps; teams that need structured blueprints for AI coding agents; and users who want to manage tasks and projects with local open-source agents.
Limitations: Credit usage is metered, and you need to purchase beyond the free range; the free version does not include advanced features (such as site scanning, custom blueprints, and saved collections); the three open-source tools are not part of the suite, run locally, and currently no other platform support or further technical details are provided.
