AIOS Release History: From Idea to Five Products
Three months, more than a hundred releases, and one idea that never changed. This is where the release notes start: a short account of how AIOS went from a first commit to a family of five products, with a chapter for each stage in the order it happened.
The idea
Most planning software asks you to learn it first. You fill in forms, pick tags, drag cards into columns, and the moment you stop feeding it, it stops being true.
AIOS started from the opposite end. You write your day the way you would on paper, and the software does the rest — turning plain sentences into tasks, calendar events, routines and a ranked plan for the day. The note is both the source of truth and the interface: the task list and the calendar are indexes built from what you wrote, and when they disagree with the note, the note wins.
A few rules were set early and have held through every release since:
- Deterministic first. Parsers, not AI models, work out what you meant. A model is asked only when a sentence genuinely cannot be read, and it never edits your notes itself.
- One door to the AI. Every model call goes through a single path, enforced by a test that fails the build if a second one ever appears.
- AI may move things, never delete them. Deletion is the user's alone, and every automated action is written to a log inside the note it touched.
- Private means private. A note marked private cannot reach a model or the public site, by design rather than by setting.
- Tested before it ships. The regression suite grew from 245 checks in July to more than 6,700 by late September, and every known defect gets a failing test before it gets a fix.

The chapters

Where it is now
AIOS is free to start at caligoarts.com/aios, with the AI assistant on a paid plan. The standalone apps — AIOS Receipts, Memories Journal and AIOS Skills — can be bought once and are included in a plan, and the AI Council can be asked a question with no account at all.
Everything above runs our own business every day, and it is the same system behind the AI integration work and custom software we build for clients. New releases are added to this section as they ship.
