About

Fastio is a collaborative content workspace designed to help teams and AI agents work together using the same files, folders, and projects. The platform enables users to store, organize, share, and manage content while supporting real-time collaboration, comments, approvals, and secure client portals. Fastio integrates with popular AI tools such as ChatGPT, Claude, Gemini, Cursor, and other MCP-compatible agents, giving them controlled access to workspace data. Built-in AI capabilities, including the Ripley assistant, help teams automate workflows, retrieve information, and perform tasks directly within the platform. Fastio also offers structured data extraction from documents, spreadsheets, images, videos, and handwritten content through customizable metadata views. With enterprise-grade security, audit logs, encryption, and developer-friendly APIs, Fastio provides a centralized environment for human and AI collaboration.

About

Proof is an agent-first document editor built for agents and humans to collaborate. It gives teams a shared document where humans and AI can write together, suggest edits, leave comments, and track who wrote what. Every character carries provenance, with a colored gutter showing authorship, so users can distinguish human-written text from AI-written text. When an AI edits a document, Proof creates suggestions like track changes, with insertions and deletions that users can accept or reject one by one. AI agents can also comment on specific text to explain reasoning, ask questions, flag issues, or continue a conversation inside the document. Users can create a document, share the link with agents such as Claude Code, ChatGPT, Codex, or OpenClaw, and collaborate through a shareable workspace instead of passing around .md files. Proof supports use cases such as bug reports, PRDs, implementation plans, research briefs, growth reports, copy audits, strategy docs, memos, proposals, etc.
