Who made each change, when they worked, which body of work it belonged to, and what waits on you. Each part is shown below with an example day.
Commits, pull requests and reviews come from GitHub with the person who made them. Agents report their own runs with a run key. Cast keeps every name and says how it knows each one.

A session is one stretch of time and everyone who worked in it. Your sessions are inferred from your activity and never run past 16 hours. An agent’s run is declared: its start and end come from the run itself.
Each quantity is named for its participant: your minutes, each agent’s declared minutes, and the clock span. They are never added together.

PR Fixer: 3 runs named no work between 04:45 and 05:40.
A stream is one body of work across pull requests, repos, people, agents and days. Its works are the PRs, branches and issues inside it.

Today fills in while it happens. Any past day opens the same way and reads as it happened: who worked when, in which session, on which stream. Move the time to read the day.
Ready at 8:00 in your own time zone. On weekdays it also comes by email. It opens with what needs you, then yesterday grouped by stream, then one line for each agent or bot that ran while you were away.

Every list opens with the tasks that wait on you, before any history. Capture a task in one line, snooze it to another day, or mark it done. When a task closes itself, it says so in plain words, and the evidence sits behind “Why?”.

PR Fixer pushed a rebase at 04:38 and the PR merged at 04:52, which settles the task you captured on Monday.

Ask your diaryEnter
Ask in plain words. Answers come from your sessions, works and streams, and each one links to the pages it was read from. Pick a question to see an answer from the example day.
Chat over your diary is part of Pro.
Any agent that can send a run report. Claude Code, Codex, Paperclip agents, a shell script or a CI job each get a run key. Agents that only act through GitHub, like review bots, are recognised by their account.
Your minutes come from sessions DevDiary infers from your activity, and a session never runs past 16 hours. An agent’s minutes come only from the start and end its run declares. The two are never added together.
Open Cast. It lists the names it saw but cannot place, and one click says “That is me”. You can rename an agent, say who it works for, or merge two names into one.
Activity, not your editor. Commits, pull requests, reviews and their line counts come from the GitHub App on the repos you choose. Agents send the start, the end and the works they touched.
