Pith writes the notes for you. Obsidian hands you a blank vault.
Obsidian is the power-user's local-first Markdown vault — endlessly extensible, plugin-rich, and the de-facto home for Zettelkasten and personal knowledge management. That power is also its tax: every note, link, folder, and workflow is yours to author and maintain. Pith is the inversion. You bookmark what you read, and the wiki — concept pages, citations, links — builds itself. Obsidian rewards disciplined daily note-taking; Pith rewards reading. They are different contracts with your time, and the right answer depends on which one you'll actually keep.

When Pith wins
You admire the Zettelkasten but never kept it up
Luhmann's slip-box worked because he wrote a handful of atomic notes a day, for decades. Most people who set up an Obsidian vault for the same purpose abandon it — the daily writing is real work. Pith gives you the output (linked, citable concept pages) from the articles you already read, with no card-writing to keep up.
You read more than you write
Obsidian optimises authoring. If your week is 20 articles read and 3 notes written, the vault captures the wrong three. Pith builds your knowledge from the 20 — the reading compounds whether or not you ever open the app.
You serve clients and need it citable
Pith gives each client a per-client wiki, briefing, and activity stream, and every claim cites its source bookmark. You can model this in Obsidian with folders and plugins — but you build it, and you maintain it, forever.
Where Obsidian wins
Where Obsidian wins
Local-first ownership (your notes are plain files on your disk, no vendor in the loop), near-infinite extensibility (plugins, custom CSS, Canvas, Dataview), offline-first, and free for personal use. And the Zettelkasten practice itself: if you *want* to write atomic notes and think by linking them, that act of writing is the value — Pith deliberately doesn't replace it. For thinkers whose primary tool is the note they author, Obsidian is unmatched. Many people run both: read into Pith, write the few notes the reading provokes in Obsidian.
FAQ
Can Pith replace Obsidian?
For a reading-driven knowledge layer — per-topic wikis, per-client knowledge, citations — yes. For a hand-authored vault, daily note-taking, and plugin-driven custom workflows, no. Many users keep Obsidian for their own writing and add Pith for the reading.
Is Pith a Zettelkasten tool?
Not strictly. A Zettelkasten is built from atomic notes you write; Pith's pages are concept-level and auto-built from sources you read. The spirit (linked, accumulating knowledge) overlaps, but the mechanic is opposite. See our Pith vs. Zettelkasten comparison for the method-level take.
Does Pith have backlinks like Obsidian?
Pith links pages to the bookmarks that built them (citations) and surfaces related concepts, but it doesn't ask you to author [[wikilinks]] by hand. The links come from synthesis, not manual cross-referencing.
Can I keep my notes local like Obsidian?
No — Pith is a hosted service (data in Frankfurt, never used to train models). If local-first, offline-by-default file ownership is a hard requirement, Obsidian is the better fit.
Is Pith free like Obsidian?
Obsidian is free for personal use; Pith has a 14-day trial then a flat per-seat price. Pith does more of the work for you (synthesis, briefings, capture) — you're paying for the absence of maintenance.
Can I import my Obsidian vault?
There's no direct importer — an Obsidian vault is authored prose, and Pith expects sources to synthesise. The cleaner bridge is to bookmark the original articles your notes were about, so Pith builds citable pages from the sources themselves.
Does Pith have plugins?
No. Pith is intentionally opinionated — fixed, well-tuned surfaces rather than a plugin ecosystem. If you love customising and extending your tools, that's an Obsidian strength Pith doesn't try to match.
Where does my data live?
Frankfurt, Germany. We don't train models on your content. Obsidian's data lives wherever your files do (your machine, plus optional paid Sync).
Can I use both?
Yes, and it's a sensible split: Pith as the inbound reading memory (capture, synthesis, briefings), Obsidian as the place you author your own atomic notes. They don't fight.
