One app for the whole plan.
Everything, in one place
Four tools that finally agree with each other.
A task with a date is a calendar event. A branch on a map is a task. A phase on the timeline is all of them at once. Nothing is entered twice.
02Mind maps
Follow a thought until it becomes a plan
Branch an idea in any direction. Albireo keeps the layout readable as it grows, and every node is a task waiting to happen.
03Calendar
A week you can take in at a glance
Tasks with a due date land on the calendar automatically. Move a block and the plan behind it moves with it.

Same job. Fewer strings.
Everything is out of the box.
Both of these are good software and we are not going to pretend otherwise. We just got tired of choosing between owning your data, having a calendar, and not renting the app monthly to use it.
| Capability | AlbireoPrivate, complete, and paid for once. | NotionA great app for people who don't mind their notes living on someone else's server. | ObsidianGets local-first right, then hands you a plugin store and calls it a feature set. |
|---|---|---|---|
| Opens without an account | Yes | No | Yes |
| Notes stored on your disk, not a server | Yes | No | Yes |
| Tasks, mind maps, calendar and timeline in the core app | Yes | Partly | Plugins |
| Ships without an AI assistant | Yes | No | Yes |
| Full feature set, no subscription required | Yes | No | Sync costs extra |
A genuinely generous free tier. One small payment, once, if you want the rest.
No seat pricing, no annual renewal, no feature you already paid for moving behind a new plan next year. Buy it once. Keep it.
Compared against publicly documented features and pricing as of August 2026; software (and pricing pages) move, so check for yourself. Notion and Obsidian are trademarks of their respective owners. Albireo is not affiliated with, endorsed by, or built on either — we would rather earn the switch than pretend they are bad tools.
Your work never leaves
this device.
Albireo has no servers, because it has nothing to send. Every task, map and timeline is written to local storage and stays there.
No cloud
There is no server to sync to. Your database is a file on your device, and it never leaves unless you export it yourself.
No account
Nothing to sign up for, nothing to sign in to. No email, no phone number, no analytics SDK counting your taps.
No AI bloat
No assistant rewriting your notes, no model reading your plans. Albireo does what you ask and nothing more.
Made by Cygnus
A small studio building software that respects the person using it. Albireo is the first thing we have shipped, and it sets the rule for everything after it.
