Keep your whole company in a form AI can read.
Obsidian, Notion, GitHub —
for everyone who found each one almost fit.
Run your company as a directory,
with your team.
CLI, Markdown, AI members, folder-level permissions —
an AI-native shared file system.

What "almost fits" actually means
Every tool in your stack is strong on its own.
In the AI-native era, each one falls short in exactly one way.
Writing locally feels irreplaceable.
— The moment you hand it to a team, that feeling ends.
Great for a team to work in together.
— But what you wrote never really lives on your machine.
Version control and permissions are near-perfect.
— But you can't hand your sales colleague a PR.
Sharing and search both work fine.
— But AI won't turn your PDFs into a table.
Feature 01
Represent your company as a directory
Folders for departments, files for cases. Hold your company's actual structure as a directory — no extra layer of abstraction.
- A UI non-engineers can use (not a GitHub-style PR workflow)
- Folder- and file-level permissions apply directly
- Export as plain `.md` / `.html` — no vendor lock-in
Directory tree
Feature 02
Manage AI members with the same permissions as people
scribe-bot and researcher sit right in your member list. Grant Read / Edit / Admin through the same interface you use for people.
- No special permission flow to learn for AI
- Restrict per directory — e.g. "this AI only sees product/"
- Every AI action is auditable at the same granularity as a human's

Feature 03
Drop in a PDF, get a table
Invoices, receipts, contracts. Drag and drop turns them into a searchable, structured table — including totals across multiple PDFs.
- Extract from multiple PDFs at once
- AI infers the columns automatically; adjust them by hand anytime
- Extract into an existing table with a custom schema
PDFs
Transactions
| Date | Vendor | Amount |
|---|---|---|
| 4/30 | ABC Inc. | $1,200 |
| 5/15 | ABC Inc. | $985 |
| 5/20 | Vendor A | $342 |
Native MD / HTML rendering
Both Markdown and HTML open as-is, at docs-site quality.
CLI and Web, both
Write from CI with the `astar` command, and see the same world in the Web UI.
Three-layer memory
Personal memory (preferences), tenant memory (org rules), workspace memory (project context). AI remembers context permanently, so you stop re-explaining it every time.
Chat app integrations
Ask the AI from Discord, Slack, LINE, or ChatWork. No need to leave the tools you already use.
MCP Server
External AI tools like Claude Code and Claude Desktop can use Astar as a data layer. Supports Streamable HTTP.
Skills & schedules
Define and share workflows as named skills. Set up recurring tasks in plain language — AI runs them on schedule.
Every option here is strong.
Here's exactly where they differ.
No exaggeration — side by side, axis by axis.
| Axis | Astar | Notion | Obsidian | GitHub |
|---|---|---|---|---|
| Local file behavior | Your local .md files just work | Cloud-only | Local-first | Local, via PR |
| Team sharing | Instant, per folder | Instant, per page | Via plugin | PR / branch |
| AI-native | AI members alongside people + 3-layer memory | Personal prompts only | Individual plugins | Copilot-centric |
| Permission granularity | Folder / file level | Page level | No concept at share time | Repo level |
| MD / HTML rendering | Docs-site quality + wiki-link compatible | Proprietary cloud format, .md is second-class | Best-in-class local rendering | Rendered as code |
| Non-engineer friendly | Fully in the UI, CLI optional | Strong | Built for individuals; sharing is a workaround | PR culture is the barrier |
| External integrations | MCP + Discord/Slack/LINE/ChatWork | API + Slack notifications | Plugins | API + Actions |
