Notes become next steps.

A Tasks dashboard with filters, due dates and snooze. Bring tasks together without moving them out of your Markdown.

English / עברית / русский

Your words, your direction.

Hebrew and right-to-left text, Russian and mixed-language notes. Light and dark themes for different working hours.

SAFE SAVE

Change the note.
Keep a way back.

Atomic saves, per-note history and crash-recovery drafts. Edits are checked against the file on disk, so an external change can be surfaced as a conflict.

Read the save behavior ↗
  1. Compare the base.Check whether the original file changed outside Okilum.
  2. Write atomically.Persist through a temporary file before replacing the note.
  3. Keep recovery separate.Draft recovery protects work without silently overwriting the source.
What's coming / The vision

From thought.
To action.

Today, Okilum is a local Markdown editor and viewer. Next, we want to connect your ideas, context and agent work into an optional second brain.

VISION / OPTIONALBrain

Thought → action.
Context retained.

A product vision, not a screenshot or a feature available in this desktop beta.
PROTOTYPED

Brain · your second brain

Connect your project knowledge: ideas, decisions, sources and the next useful action. Keep the original context with the outcome. Brain is an experimental prototype, not available in this desktop beta.

IN DEVELOPMENT · OPTIONAL SERVICE

Inbox · a place to think

The vision: capture a thought from anywhere, explore it in conversation and turn it into a note or an actionable brief. A separate Inbox would bring together captures and questions that need your attention.

PLANNED

LLM & agent tracker

Follow conversations and delegated work in one place: what is running, what needs your input and what came back. Keep results linked to the context that started them.

All of this is future direction, with no release date promised. Brain, Inbox and integrations are optional. Your local desktop app works independently, without an account or a backend.

Try it on your desktop

Your next note starts here.

Free. Open source. Yours to inspect and improve.

All builds & checksums ↗

Okilum is in active development. Keep normal backups of your notes.

A few useful details

Before you open
your vault.

No migration ceremony.
No account to get started.

Can I open my existing notes folder?

Yes. Open a folder of Markdown files directly, without import. Okilum understands wikilinks, backlinks, aliases, embeds and frontmatter properties. Your notes remain ordinary files on disk.

Does Okilum sync my notes?

No built-in sync is available in this beta. The desktop app works with files on your machine. It does not require an account or an internet connection for local note work.

How much does it cost?

The desktop app is free and open source under the MIT license. You can inspect the code, build it yourself and contribute on GitHub.

Is there an iPhone or Android app?

Not in this beta. Okilum is currently a desktop app for macOS, Windows and Linux, with platform-specific availability as listed above.

Do I need Inbox?

No. Inbox is part of the planned optional service layer. The desktop app works independently with your local vault, without an account or an internet connection for local note work.
