Dexi vs Obsidian

Dexi is an all-in-one workspace where notes, bookmarks, newsletters and RSS feeds land in one searchable knowledge graph; Obsidian is a free, local-first Markdown knowledge base with a plugin ecosystem thousands strong. Here’s how they compare on pricing, platforms, linking, search, capture and collaboration — and how to decide between them.

What is Dexi?

Dexi is built on a simple observation: your knowledge doesn’t only come from notes you type. It arrives as web pages you want to keep, newsletters you forward, and articles flowing through RSS. Dexi puts all of it in one workspace — everything you save becomes a note, so one search covers your whole reading life. Structure emerges as you write: #hashtags become tags, @mentions become people and sources, and [[wiki links]] connect ideas into a private knowledge graph you can explore in 2D or 3D.

Search works two ways — instant full-text search, and semantic search that finds notes by meaning even when the words don’t match. Capture happens from anywhere: a Chrome extension, a bookmarklet, the iOS share sheet, or simply emailing an article in. Teams can share individual notes with per-note control, and an MCP server lets Claude and other AI assistants search, read and write your notes directly. Free for up to 1,000 notes; Solo is $5/month and Team is $10/member/month.

What is Obsidian?

Obsidian stores your notes as plain Markdown files in a folder on your own device — a “vault” you can read with any text editor, back up however you like, and keep forever. On top of those files it layers backlinks, a graph view, a Canvas whiteboard, and Bases (native database views over your notes, added in 2025). The app is completely free, including for commercial use since early 2025.

Its defining feature is the community: roughly two thousand plugins extend it with everything from spaced repetition to Kanban boards to AI integrations. Official add-ons are paid — Sync ($4/month, end-to-end encrypted) keeps vaults identical across devices, and Publish ($8/month) turns notes into a public site. There’s no web app; Obsidian runs as desktop and mobile apps against your local files.

Where Dexi shines

• One workspace for every input — typed notes, saved web pages, forwarded newsletters and RSS subscriptions are all searchable together instead of living in separate apps.
• Zero-upkeep organization: tags, people and wiki links are written inline as prose, so notes file themselves without folders or manual metadata.
• Semantic search plus a “similar notes” view finds ideas by meaning — you search with today’s vocabulary and still find last year’s thinking.
• First-class AI-assistant support: an MCP server (OAuth-secured) lets Claude search, create and update your notes from claude.ai, Claude Code or Claude Desktop.
• Simple, cheap plans: free up to 1,000 notes, $5/month for unlimited, with team sharing and team-wide search at $10/member/month.

Worth knowing: Dexi is web-first and cloud-based — there’s no offline desktop app or local file storage. It’s a rich-text document editor rather than an outliner, so block-level references and transclusion aren’t the model. There’s no built-in spaced repetition.

Where Obsidian shines

• True data ownership: plain Markdown files on your disk, readable by any app, with no account required and no lock-in.
• The largest plugin ecosystem in the category — if you want a workflow, someone has probably built it.
• Free for personal and commercial use; you only pay for optional Sync or Publish.
• Bases and Canvas add database views and visual thinking without leaving your local vault.
• End-to-end encrypted sync (as a paid add-on) for the privacy-conscious.

Worth knowing: There’s no web app, and multi-device use effectively requires paid Sync or DIY setups. Collaboration is weak — shared vaults exist but there’s no real-time co-editing. Out of the box it’s fairly bare; the power comes from configuring plugins yourself, which is a hobby in its own right. Capturing web content, newsletters or feeds means assembling extensions and plugins rather than anything built in.

Which should you choose?

Choose Dexi if:

• You want bookmarks, newsletters and RSS feeds in the same searchable space as your notes — not a separate read-later app.
• You want organization to happen as a side effect of writing, with no folders or filing.
• You want your AI assistant (Claude or any MCP client) to work with your notes directly.
• You want team sharing without moving your whole workspace to a heavyweight team tool.

Choose Obsidian if:

• You want your notes as local files you fully control, independent of any company’s servers.
• You enjoy tinkering and want to assemble a personalized system from plugins.
• You work offline often or in environments where cloud tools are off-limits.
• You want a free tool with no note limits.
