Value for money
BPro is $79 once, on 3 devices at a time, with every later Pro feature included. That's about 13 months of a typical $5.99 a month plan here, so just past our line for an A. The docs say the price goes up as Pro features are added, and the AI still needs your own API key.
AFree, and the site says it always will be. It's open source under the Apache 2.0 licence, with no paid version to buy.
Free plan and trial
APersonal is free: the WYSIWYG editor, unlimited workspaces, daily and weekly notes, graph view, full-text search, templates and Mermaid diagrams. The vendor says the core features will always be free. Most people could stay here. You also get 7 days of Pro with the download.
AThe whole desktop app is free on Mac, Windows and Linux, with no account and no server. There's nothing to upgrade to.
Features
AWikilinks to a note or a single heading, backlinks, a graph, and a Daily Desk that moves yesterday's unfinished tasks into today. A Spotlight-style capture window drops thoughts into an Inbox. Pro adds properties, table and kanban views, note sharing and a chat over your notes.
BSliding panels that keep your path, a map built from where you've been, Markdown styled as you type, wiki links with backlinks, nested tags and a query language whose queries you can save. A good set. But it's an open alpha, there's no built-in sync or collaboration, and export to HTML is still on the roadmap.
Ease of use
BNo store rating to go on, so a B is our ceiling. It's a normal install, you edit the formatted page directly, and the main features are there without adding plugins. Sync is yours to arrange, through a file-sync service or the built-in Git sync.
BNo rating on record, so a B is as high as we go. Nearly every action has a shortcut you can change, with a command palette for the rest. Just remember the download page calls it an open alpha.
Platforms and integrations
BMac, Windows and Linux, a browser clipper, and Git sync to GitHub or GitLab. On phones there's only an iOS beta on TestFlight for eligible Pro users, and no Android app is listed. So it's a desktop app for now.
BMac, Windows and Linux, with Linux builds on Flathub too. iOS and Android sit under "Much Later" on the roadmap. Syncing is up to you: the site points to Git, iCloud, Drive or Dropbox for the files.

Who each one suits

Octarine

  • Writers who want Markdown notes kept as local files
  • People who prefer a one-time license to a subscription
  • Those who want linking, daily notes and views built in, not added as plugins

Tangent Notes

  • Writers who follow links from note to note and want to keep their place

  • People who want Markdown notes with no account or server

Worth knowing

Octarine

  • Properties, filtered views, note types, focus mode, note sharing and every AI feature need the $79 Pro license.
  • There is no public phone app: an iOS beta runs on TestFlight for eligible Pro users, and no Android app is listed.
  • AI features need your own API key or a local model, and syncing relies on a file-sync service or the built-in Git sync.
  • Pricing is early-access: the docs say the price goes up as Pro features are added, while earlier buyers keep all future Pro features.

Tangent Notes

  • Desktop only: iOS and Android support is listed under "Much Later" on the roadmap.
  • The download page calls the app an open alpha, and the roadmap says it is still in active development.
  • There is no built-in sync or collaboration; the site points to Git, iCloud, Drive or Dropbox for syncing the files.
  • Export to HTML or simplified Markdown is still on the roadmap.

Key features

Octarine

Markdown files you keep
Notes are plain Markdown files in a workspace folder you pick, and core note-taking works offline. Files sync through any file-sync service or the built-in Git sync to GitHub or GitLab.
Daily Desk
Daily and weekly notes are part of the free plan, and unfinished tasks from yesterday's note can be moved into today's without copying.
Links, backlinks and graph
Wikilinks can point at a note or a single heading and carry an alias. Backlinks and mentions are listed in their own sheet, and a graph view maps the workspace.
Properties and Views
On Pro, Note Types start new notes with a set of properties, and Views filter, sort and group notes by any property in a table or kanban layout.
Quick Capture and Inbox
A Spotlight-style window opens over any app to take down a thought, which lands in an Inbox to be sorted into notes later.
Ask Octarine and Writing Assistant
On Pro, a chat over your notes can create, update and move notes, and an assistant rewrites text inline. Both need your own API key or a local LLM.

Tangent Notes

Thread View
As you follow and create links, the notes behind you stay open as horizontally sliding panels, so you can move back and forth along the path you took.
Map View
A branching map of nodes and connections is built automatically from your writing and navigation, giving an overview of where you have been.
Markdown styled as you type
Markup is hidden once you move on and reappears when you return. Headers, highlights, lists, YAML front matter, LaTeX math, Mermaid diagrams and highlighted code blocks are supported.
Wiki links and backlinks
Double-bracket links connect notes by filename with autocomplete, and each note knows what links to it. Links in notes that come from Obsidian keep working.
Tags, to-dos and queries
Notes take nested tags and to-do checkboxes, and a custom query language finds notes by links, tags, to-dos or text. Queries can be saved and reused inside other queries.
Keyboard control and focus mode
Nearly every action has a customizable shortcut, with a command palette for the others. Focus mode narrows the view to one note, paragraph or sentence.
