Quiet release of a single-user AI assistant

Why Orbitly is built as a Personal OS for one person, not SaaS for thousands.

Most AI products in 2026 chase the masses: teams, workspaces, ARR metrics, growth loops. Orbitly does the opposite. It's a Personal OS for one user that sees your whole life: tasks, events, finances, health, journal.

Why single-user

Privacy. No public "anyone with the link" URLs, no comments, no mentions, no workspace to be invited into. You can share a task list or a goal — by email, with people who already have an account, up to five per object. Five is a family, not a team, and the ceiling exists precisely so a shared object doesn't quietly turn into a workspace. Everything else is simply yours.

Architecture. I'm not optimizing for hundreds of thousands of users. I'm optimizing for one — myself. That unlocks things SaaS can't: cross-orbit AI correlations (sleep × tasks, mood × spending) that require seeing one person's whole life at once.

Pace. No email blasts, no A/B tests, no growth experiments on users. I just write the features I need.

What's inside

Nine sections grouped into five spheres: Time (tasks + calendar), Wealth (finance), Vitality (health), Mind (notes + journal), Identity (goals + habits). All anchored to one DB. AI correlations work on top: "when you sleep under 6 hours, you finish 47% fewer tasks on average."

Where you talk to it

The main entry point is the app itself: a record button, no forms, no fields. You say it, it lands in the right sphere. Install it from the home screen and notifications arrive there too.

Telegram is the second entry point, optional. Voice, receipt photo, forwarded message, link → same place, no menus, no forms. Handy when opening the app feels like too much, but it was never required: access to it is restricted in Russia, so building on it would be a strange bet.

Speech → parse → record in DB in ~2 seconds. Web is for browsing patterns and editing. Voice is for input.
