You want free and local-first
Obsidian's core app is free, works fully offline, and never requires an account. Mana is a hosted, paid service that works on a GitHub repo.
ComparisonMana vs Obsidian
Same plain markdown. Opposite philosophy about who does the work.
Obsidian is a superb editor for a second brain you organize by hand — folders, links, and plugins are up to you. Mana is an AI-maintained wiki: you drop in papers, articles, and notes, and an agent reads them, writes linked and cited pages, and commits every change to a git repository you own.

TL;DR
Choose Obsidian if you enjoy organizing notes yourself and want a free, local-first editor with a huge plugin ecosystem. Choose Mana if you want the organizing done for you — an AI agent that turns raw sources into a linked, cited markdown wiki and shows its work as git diffs. Because both use plain markdown, you can even use them together: Mana maintains the repo, Obsidian opens it as a vault.
Being upfront: Mana is a paid hosted service in early access — not free, not open source, not self-hosted. If you need those, this guide routes you to better fits.
At a glance
| Mana | Obsidian | |
|---|---|---|
| What it is | Hosted AI agent that maintains a markdown wiki | Local-first knowledge-base editor |
| Who organizes the notes | The agent: reads sources, writes pages, links, cites, merges duplicates | You, with optional plugins for suggestions |
| File format | Plain markdown + git history in a GitHub repo you control | Plain markdown in a local vault folder |
| AI | Built in: ingestion, linking, citations, synthesis, contradiction flags | No built-in AI; community plugins (Copilot, Smart Connections, and others) that you pick and configure |
| Reviewing changes | Every agent edit is a git commit with a diff you can revert | Manual edits; git available via the community Obsidian Git plugin |
| Sync & mobile | Repo-backed sync for the Mana workflow; offline-first iOS app for capture and review | Obsidian Sync (paid add-on) or DIY git/iCloud; mature desktop and mobile apps |
| Publishing | Included in the hosted service — every commit rebuilds your wiki site | Obsidian Publish (paid add-on) or DIY static-site pipelines |
| Price | Paid hosted service in early access; pricing not public yet | Free core app; paid Sync and Publish add-ons |
Where Obsidian is the better choice
Obsidian earned its reputation. If these describe you, use Obsidian — possibly alongside Mana, but Obsidian first.
You love the plugin ecosystem
Thousands of community plugins and themes — canvas, spaced repetition, Dataview queries, kanban. Nothing else matches it.
Organizing is the point for you
Many people think by gardening their vault — naming, linking, and refactoring by hand. If that's you, an agent doing it would take away the fun part.
You need a daily writing editor
Obsidian is a fast, polished markdown editor. Mana's browser app is built for asking, ingesting, and reviewing — not long-form drafting.
Where Mana is the better choice
The honest reason vaults rot: capturing is easy, maintaining is work. Mana exists for the maintenance.
The wiki writes itself
Drop a paper, transcript, or article into /raw. The agent extracts the durable ideas, updates related pages, adds links and citations, and flags contradictions. See a real ingestion.
No plugin stack to assemble
No API keys, model pickers, embedding indexes, or re-indexing loops. Mana is fully managed: connect a GitHub repo and the agent handles the rest.
AI you can audit
Mana's work lands as git commits by default. Diff every change, revert what you don't like, and keep the history forever — the same review workflow developers trust for code.
Published without effort
Every commit rebuilds a browsable wiki site as part of the hosted service. Reading, searching, and sharing need no pipeline setup.
Obsidian AI plugin alternative: when Mana makes sense
Plenty of good AI plugins bring models into Obsidian — Copilot for chat and vault Q&A, Smart Connections for related-note discovery, Text Generator for drafting, and newer agent plugins that can edit notes with diff review.
The trade-off is that you assemble and babysit the stack yourself: provider keys, model choices, embedding indexes, plugin updates, and review flows. And most workflows center on chat and retrieval — the vault only improves if you turn answers into pages yourself.
Mana is the alternative for people who want Obsidian with AI but not another plugin to manage: a managed agent whose entire job is maintenance. Its output isn't a chat answer — it's new and updated pages, links between concepts, citations back to sources, and merged duplicates, committed to git where you can review them.
An AI second brain in files you own
Most AI second brain apps keep your knowledge in their database — leave the app, lose the structure. Mana's bet is the opposite: the durable output of the AI is the markdown itself.
That's the Obsidian instinct — plain files over app databases — applied to an AI knowledge base. The agent can read, search, and reason over your notes, but what it leaves behind is always files: pages, links, summaries, and structure that survive any tool, including Mana.
Use them together
Because a Mana wiki is a normal git repository of markdown files, it is also a valid Obsidian vault. The mechanics, concretely:
- ✓ Clone your Mana repo and open the folder in Obsidian — graph view, backlinks, and search work on Mana's pages out of the box
- ✓ Edit locally, push to GitHub; Mana pulls the latest state of the repo the next time you ask it to ingest or edit
- ✓ Conflicts are ordinary git conflicts, resolved with normal git tools
- ✓ Mana doesn't touch your .obsidian config or plugins — it only works on the markdown
- ✓ Leave either tool at any time — the markdown stays yours
Frequently asked questions
Is Mana better than Obsidian?
Neither is strictly better — they do different jobs. Obsidian is a free, local-first editor that's better if you enjoy organizing a vault yourself and want full control of your setup. Mana is better if the maintenance is the problem: it's a hosted AI agent that turns sources into linked, cited markdown pages and commits every change to git. Because both work on plain markdown, you can also use them together.
Can I open my Mana wiki in Obsidian?
Yes. A Mana wiki is a GitHub repository of plain markdown files. Clone it and open the folder as an Obsidian vault — pages, links, and raw sources work like any other vault. Mana doesn't manage your .obsidian settings or plugins; it works on the markdown itself.
Is Mana an Obsidian AI plugin?
No. Mana runs outside Obsidian as a managed service on your GitHub repo. Obsidian AI plugins run inside the editor and depend on your provider keys, models, and indexes; Mana ships the whole pipeline and returns finished commits instead of chat output.
Can I use Obsidian with AI through Mana?
Effectively, yes. Mana isn't a plugin, but because a Mana wiki is a plain markdown repository, you can keep editing in Obsidian while Mana's agent handles the AI maintenance — reading sources, linking pages, adding citations — through git commits you review.
Do I lose ownership of my notes with Mana?
No. Your knowledge base is plain markdown with YAML frontmatter and full git history in a GitHub repository you control. If you stop using Mana, you keep every file and every commit.
Is Mana free or open source?
No. Mana is a paid hosted service currently in early access, and pricing is not public yet. If you specifically want a free, open-source, or self-hosted tool, an option like Logseq is a better fit — see our Obsidian alternatives guide.
