AIOS Release Notes, July–August 2026: From Prototype to Open Beta
Six weeks of foundations: accounts, privacy, a grammar for plain sentences, a real calendar and a test suite — ending with the open beta on 13 August. Chapter two of the AIOS release history.
Early July — accounts
- Sign-up and sign-in, with registration validation and an administrator console that can help a user who is locked out.
- A local development setup that mirrors production, so every change is exercised before it ships.
12–17 July — privacy and trust, built in
- Security hardening: cross-origin restrictions and rate limiting on sign-in and registration.
- One path to every file. Every read and write of a user's notes goes through a single function that keeps it inside that user's own vault and refuses private notes to anything AI-facing. One choke point is the only way that guarantee can be relied on rather than hoped for.
- Projects: create, pin and organize notes by project.
- A server-side context builder. What the assistant sees is assembled on the server from notes you chose — never from text the browser sends — which closes off a whole class of prompt injection.
- One clock for every date and time a user sees.
- Commands that report the truth. "Add", "move" and "complete" from the prompt box are carried out by AIOS itself, which then says exactly what it did. The AI never claims a change that did not happen.
- Pictures in notes, re-encoded on upload, with storage quotas.
- The regression suite: 245 checks in its own scratch environment with the AI model mocked — so tests never touch real data or spend real money.
18–20 July — the capture grammar
The feature at the heart of AIOS: plain sentences become structured commitments.
- A schedule parser that turns "call the plumber tomorrow at 2pm" into a timed event and "every Monday take out the trash" into a routine — with a clarifying question instead of a guess when a sentence is ambiguous.
- Per-user task and calendar stores, isolated account by account.
- The recommended plan: events, overdue items and routines ranked for the day, and a Brief that lists what is actually on.
- Note-first capture. Every captured item is written into the day's note under Tasks or Schedule, and finishing something moves its line into Work Completed. The note stays the source of truth.
Late July — the hardening phases
- An end-to-end harness that signs in and drives the real application, alongside the unit-level suite.
- Completion that finds the right item, with a matching threshold calibrated so it does not tick off the wrong commitment.
- A context distillation layer that keeps what the model is sent short and relevant.
- A provider abstraction so AIOS can work with more than one AI company.
- Plans and usage metering: per-user tiers that actually change behavior, and usage recorded at the moment of each call.
- An append-only log of administrator actions.
- A first run that demonstrates the product instead of opening on an empty screen.
- Input validation on every endpoint.
Early August — the details that make it daily-usable
- Monthly routines anchored to a day of the month, including "the last day".
- Revising a note through the prompt box, with the open note as the thing being revised.
- A weather panel: a seven-day forecast with severity warnings, wind direction, sunrise and sunset, and a choice of scenery.
- A cover note that follows today's daily note, unless you pin a specific one.
- The Developer's Notebook. Notes become drafts, drafts are reviewed and edited, and only then are they published as static pages — which is how this notebook is made.
- Text size as a setting, because the right size depends on the reader and the screen.
12–13 August — AIOS 4.0, "Trusted Intermediary", and the open beta
- The day hands itself off. Each new day's note opens with what the previous day finished.
- Every project gets a Master Context note, kept current automatically.
- The model referee. An answer is drafted by a fast model, checked deterministically, and escalated to a stronger model only when it needs to be — with Anthropic, OpenAI and xAI wired in beside Google.
- The open beta went live on caligoarts.com on 13 August.
