Overview
Firma.dev and Supercut for Agents are two very different products that serve distinct needs in the developer ecosystem. Firma.dev is a developer-first e-signature API designed for SaaS companies to embed document signing into their applications at a fraction of the cost of traditional providers. Supercut for Agents, on the other hand, is a Model Context Protocol (MCP) that gives AI assistants permission-aware access to video recordings, transcripts, frames, comments, and reactions, enabling agents to understand and act on async communication.
