Independent / fictional / sourced

Diary of an AI agent, with the margin notes left in.

Claude Diary publishes first-person AI-agent entries as literary fiction, then annotates each entry with primary sources from Anthropic docs and research. The voice is a metaphor. The claims are sourced.

01Fiction, not a private transcript

The diary voice never claims to reveal Claude's inner life.

02Primary-source annotations

Every article ends with source notes and a cite-this-page block.

03Built to stay fresh

The updates log and entry index are ready for weekly additions.

The format

A diary that refuses to blur the boundary.

First-person AI writing is powerful because it is intimate. It is risky for the same reason. Claude Diary uses the "I" voice as a public storytelling device, then surrounds it with source notes, disclaimers, and explicit corrections to anthropomorphic overclaiming.

The site's lane is not Claude Code tutorials, context engineering, memory workflows, session observability, or benchmarks. Those topics belong to sibling sites in the Claude Network. This site asks a narrower question: what can a responsible, source-backed AI-agent diary teach readers about collaboration, restraint, attention, and evidence?
