Best for: A structured, hierarchical personal knowledge base you will add to for years.
A deep tree, strong linking, scripting when you want it, and a note model that scales to a genuinely enormous personal wiki. It is the most powerful option here for structured reference material, and it stores everything in a single SQLite file you can copy anywhere — which makes backup trivially reliable.

Best for: People who want Obsidian's approach without Obsidian's paid sync.
The closest self-hostable match to Obsidian's block-reference model, and unlike Obsidian it ships its own synchronisation rather than gating it behind a subscription. Block-level references change how you write once you get used to them, and SiYuan is the most comfortable place to form that habit.

Best for: Quick capture, daily notes and a personal micro-feed.
A timeline of short notes and nothing else, and that discipline is the feature. It is fast enough to be the thing you actually open, and it deliberately refuses the organisational features that make bigger tools slow to use. Treat it as an inbox, not an archive.

Best for: Envelope budgeting without a subscription to a finance app.
Included for the same reason. Budgeting is the other category people wedge into notes apps and then outgrow. Actual Budget does envelopes, bank sync and reports, and runs entirely on your own machine with a local-first data model.

Best for: Recipes you have saved from the web and never been able to find again.
The narrow, well-built case of recipe collection, which is where a lot of note apps quietly fail — recipes want structured ingredients, scaling and shopping lists, not freeform pages. Listed because "I keep my recipes in a notes app" is one of the most common reasons people end up with an unusable notes app.

Best for: Paper: invoices, contracts, receipts, anything you would otherwise scan and lose.
Not a note app, but the same underlying problem — a pile of documents you cannot search — and it solves it better than any general-purpose tool. Optical character recognition, automatic tagging and a full-text index mean a scanned invoice from three years ago is findable by any word it contains.
