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.

About

Quilva is an offline-first writing and creative workspace that brings the entire writing process into one application, from the first idea through planning, outlining, research, mindmapping, notes, drafting, editing, design and publishing. Designed for novels, screenplays, essays, books, research projects and other substantial written work, Quilva lets users organise their ideas, structure their work and develop their writing without relying on multiple applications. It also provides a different approach to authorship: rather than analysing finished text and guessing whether it was produced by AI, Quilva records evidence of how work was created, including typing, edits, deletions, pauses, writing time and typed versus pasted content. This can be used to generate a Human Authorship Certificate with a QR code for verification. Quilva works locally on the user's computer, keeping their writing and creation data under their control.
