mdedit.ai vs Obsidian for Markdown documents

See them side by side

What each editor looks like with a document open. Every frame is cropped to the same shape, so the difference you see is the interface, not the picture.

The mdedit.ai editor with a deployment runbook open in split view: Markdown source with a bash code block on the left, and the live preview on the right rendering the document heading, a Mermaid flowchart, and a table.

Where do they differ?

Every price below is the one published on each product’s own pages. The full mdedit.ai tiers are on mdedit.ai pricing.

Primary model

mdedit.ai: Documents that ship. A technical-content workspace organized around documents, folders, review, export, and publishing.
Obsidian: A vault of notes. A Markdown editor and knowledge-base app organized around local folders called vaults.

Local ownership

mdedit.ai: Local-first, plus desktop. Local-first browser drafts and a desktop app that can work with local Markdown folders. Working with local Markdown folders.
Obsidian: Files on your disk. Markdown files live in a local vault, and Obsidian keeps its metadata cache in sync with them.

Knowledge connections

mdedit.ai: Folders and links. Folders, documents, links, and technical diagrams, with no knowledge-graph claim.
Obsidian: The whole point. Internal links, backlinks, graph-oriented knowledge work, Canvas, and community plugins are central strengths.

Collaboration and review

mdedit.ai: Live, with review states. Live same-document co-editing plus permissions, comments, suggestions, assignments, replies, and resolution. Sharing and collaboration.
Obsidian: Shared vaults via Sync. Every collaborator needs Sync; changes sync and merge, but live same-file cursors are not supported.

Apps and extensibility

mdedit.ai: Browser, desktop, mobile, CLI. Plus a VS Code extension and an MCP server that lets agents read and suggest changes. The VS Code extension.
Obsidian: Desktop, mobile, plugins. A large community plugin ecosystem and a public plugin API; Obsidian’s own pages do not describe a browser editor.

Cost and publishing

mdedit.ai: Free tier, then US$6.99. Standard is US$6.99 per month or US$39.99 per year and Premium is US$17.99 per month or US$129.99 per year, with hosted links plus configured external destinations. How publishing works.
Obsidian: Free core, paid add-ons. The core app is free without sign-up, and Sync and Publish are separately priced.

What each one gives up

Neither tool wins everywhere. These are the parts worth knowing before you commit.

mdedit.ai is not a personal-knowledge-management graph and does not try to replace Obsidian’s backlinks, graph, canvas, or plugin ecosystem.
Obsidian is free without sign-up and stores Markdown locally; paid Sync and Publish are optional services.
Obsidian shared vaults support team access through Sync, but its official help says same-file collaborative live editing is not currently supported.

Switching from Obsidian?

An Obsidian vault is a folder of Markdown files, and the mdedit.ai desktop app works with local Markdown folders, so a document can move between the two without leaving your machine.

Point at the vault folder
The notes are already plain Markdown. The desktop app opens the local folder, so nothing has to be uploaded to move one document across. How the desktop app works.
Structure does not transfer
mdedit.ai does not reproduce backlinks, graph view, Canvas, or plugins. Keep the vault for that work and move only the documents that have to be reviewed, exported, or published.
In and out of Markdown
The Markdown converters bring PDF, Word, HTML, PowerPoint, Excel, and EPUB source material in, and Pandoc-backed export writes PDF, DOCX, HTML, EPUB, and more on the way out. Markdown converters.

Common questions

Not currently. Shared vaults give a team access through Sync and changes merge, but Obsidian’s official help says same-file collaborative live editing is not supported, so two people in one note at once is a conflict to resolve rather than a supported flow. mdedit.ai supports live same-document co-editing with permissions.

The core app is free without sign-up, and Sync and Publish are separately priced optional add-ons. That makes the honest cost comparison depend on your workflow: solo and local stays free on Obsidian, while a shared or published document pulls in add-ons on one side or a plan on the other. The mdedit.ai free tier and paid tiers are on mdedit.ai pricing.

No. mdedit.ai is not a personal-knowledge-management graph and does not replicate backlinks, graph view, Canvas, or the plugin ecosystem. Plenty of people keep both: the vault for thinking, mdedit.ai for the documents that leave the vault and go through review, export, and publishing.
