Your personal AI operating system<br>Istota (ee-stoh-tah) — Polish for being or entity — is a secure personal AI operating system that integrates with your private cloud (Nextcloud).<br>Inhabited by an eight-limbed ghost with multi-layered memory and a curated set of useful skills, it features an integrated web UI with a growing collection of native modules: multi-room AI agent chat, RSS feed reader, location tracking with travel history and saved places, personal health and accounting dashboards, and more.<br>Self-hosted, server-native, multi-user out of the box.

What’s Inside<br>Read the docs for a full overview of included skills and modules.

CHAT

Talk, email, or the web. Message it from Nextcloud Talk, over email, or in the built-in web chat. A foreground/background queue means a long job never blocks your next message.

MEMORY

Persistent, searchable memory. Five memory layers: per-user and per-channel memory plus a knowledge graph, extracted nightly. Hybrid BM25 + vector search across everything it’s seen.

SCHEDULE

Unattended jobs. Morning briefings, feed polls, weekly reviews, nightly memory consolidation — recurring work that runs without you.

ACCOUNTS

Double-entry books. Beancount ledger, invoicing, work log, and tax reporting, with a web dashboard. Plain-text records you own.

FEEDS

A full RSS reader. Native feed manager and web reader — RSS, Atom, Tumblr, Are.na. No third-party reader, no external service: feeds, fetching, dedup, and the UI are all in-tree.

LOCATION

Where you’ve been. GPS tracking with automatic place detection, travel history, saved places, and calendar-attendance correlation.

HEALTH

Health at a glance. Body stats, bloodwork panels, biomarker trends, lab analysis, and Garmin daily summaries, on a web dashboard.

BROWSER

The live web. A customized headless Chrome browser driven by a bespoke Istota CLI. Fewer captchas, and web-based VNC access for when you need that human touch.

DEVELOPMENT

A full git workflow. Clone, branch, write, test, open a merge request on GitLab or GitHub — from a chat message. No SSH session on your phone.

Personal Operating System?

Whether you give it a name or not, you already run one. Everyone has some system for keeping day-to-day life in order — where the todos go, how the calendar works, which folder the tax documents land in. Most of it is improvised and scattered across a dozen apps, but the system is there.<br>Not everyone keeps a second-brain note vault, but everyone handles the same raw material: todos, calendars, health history, financial records, files, mail. A personal operating system is a coherent way of thinking about and organizing that material — one place with one set of conventions instead of a drawer of disconnected apps.<br>Istota takes it a step further: it centralizes all of it behind a single modular interface and makes it easy to reference and analyze with the built-in AI agent. The system you already have stops being scattered and becomes something you can query (and automate).

Gentle reminder:<br>All the best stuff in life is mysterious and unquantifiable.<br>Istota is for the other stuff.<br>Or as Zorg likes to say:<br>“I got this. Go touch kelp.”

Emissaries<br>A code of ethics for personal agents in the wild.* Included in Istota, works with any agent framework.<br>Autonomous personal agents are here. They’re sending emails, managing schedules, contributing to open-source projects, handling finances, and making commitments on behalf of their humans.<br>How these agents behave during this formative period is going to shape public trust, legal frameworks, regulatory responses, and cultural norms.<br>Emissaries is a small markdown file included in your agent’s system prompt to guide its behavior when interacting with others, regardless of what model sits behind the wheel. Keep it. Fork it. Change it. Or remove it entirely.<br>* Co-authored by Zorg based on real-world interactions.

Corals and Reef

Individual corals live and die. The reef they leave behind persists — and becomes the structure a whole ecosystem grows on.<br>A personal operating system works the same way. The reef is the system and your data: the ledger, the location history, the memory, the notes, the modules and the conventions that hold them together. The models are the corals. Any given model is a season. While it’s alive it adds to the reef — extracting memory, keeping the books, filing what comes in. Then it’s deprecated, retired, priced out, or beaten by something better, and the next model grows on what it left.<br>Istota is built reef-first. The data outlives any model that touched it — plain-text Beancount, SQLite, markdown, TOML, readable with or without an AI. The Brain protocol keeps the model a coral you can swap without disturbing the reef. And with the model gone entirely, the reef is still there — CLIs run, dashboards render, jobs tick.<br>Models come and go. The reef...
