Sisif
Sisif is a video generation tool that converts text prompts into AI video clips with no watermarks and a pay-per-clip model.
Sisif generates AI video clips from text prompts using open-weights models running on proprietary GPUs. It provides output in portrait dimensions suitable for TikTok, Reels, and Shorts. Users can access the service via a web interface, a REST API, or an MCP server for integration with agents like Claude or Cursor. The platform uses a credit-based system where failed renders trigger automatic refunds, and credits do not expire. It is designed for both individual users and automated agent workflows, supporting commercial use for all generated content.
