Knit is an AI tool that provides a convenient workspace for managing and building prompts. It allows users to store, edit, and run prompts in one place, eliminating the need for manual note-taking or copy-pasting. Knit offers features like a playground for interactive prompt exploration, project organization with access control and settings, collaboration with team members, and version control for prompts. The tool emphasizes security, encrypting sensitive data in transmission and storage. In the future, Knit plans to support multiple AI models and the use of multiple variables in prompts. Potential applications for Knit could include natural language processing tasks, content generation, and AI model development.
