ZenNotes Review (2026): Pricing, Features & Honest Verdict

TLDR

ZenNotes is a free, open-source, Vim-native Markdown notes app that keeps everything as local plain-text files. It targets developers with keyboard-first editing and a built-in MCP server for Claude and Codex. Best for: Vim users who want a local-first notes vault. Price: Free (open source). Rating: 7.2/10.

What is ZenNotes?

ZenNotes is a keyboard-first Markdown notes app that stores your notes as plain .md files in a local vault. There is no database and no proprietary format, which means no lock-in and the ability to open an existing Obsidian vault directly. It is built for people who live in the keyboard, with full Vim editing baked into the editor rather than bolted on as a plugin.

We dug into the project and found it is the work of solo developer Adi Bhanna, released under the MIT license through the ZenNotes GitHub organization. It is genuinely new, having launched around April 2026 and crossed roughly 1,500 GitHub stars within its first couple of months, with the v2.4.0 release shipping on June 19, 2026. Note that there are several unrelated apps sharing the ZenNotes name on app stores; this review covers the one at zennotes.org. It runs as a native desktop app on macOS, Windows, and Linux, and can also be self-hosted as a web app via Docker.

The reason it matters now is timing. Note-taking has split into two camps: cloud SaaS apps like Notion that own your data, and local-first tools like Obsidian that keep it in plain files. ZenNotes plants itself firmly in the second camp and then adds a 2026 twist, native AI tooling through MCP, which most local-first apps still treat as an afterthought. That combination, plain-text ownership plus first-class AI access, is the bet the project is making, and it is a reasonable one for the developer crowd it targets.

What Are ZenNotes’s Key Features?

Full Vim editing

This is the core draw. ZenNotes ships real Vim editing: motions, operators, registers, marks, macros, and an ex command prompt. It also supports split views, floating windows, and a distraction-free zen mode. If you already think in Vim, writing and navigating notes here is fast. If you do not, expect a real learning curve before it clicks.

Rich Markdown rendering

Beyond plain Markdown, ZenNotes renders KaTeX math, Mermaid flowcharts, TikZ, JSXGraph, and function plots, plus CSV-backed tables. That makes it a strong fit for technical and academic notes where formulas and diagrams matter, not just bullet lists. Backlinks, wikilinks, tags, and full-text search round out the knowledge-base side.

Built-in MCP server and CLI

ZenNotes ships a first-party MCP server with one-click setup for Claude Code, Claude Desktop, and Codex. That lets AI assistants read, search, and manage your notes directly. There is also a zen command-line tool for quick capture and search from the terminal. This native AI tooling is the feature that sets it apart from older note apps. For someone who already drives a lot of work through an AI assistant, being able to point that assistant at your knowledge base without copying and pasting is a meaningful workflow change, and it is the kind of integration that competitors will likely scramble to add later.

Local-first vault organization

Notes live in a local vault with tasks, tags, wikilinks, backlinks, a fuzzy finder, ISO-dated daily and weekly notes, plus archive and trash. Because the storage is plain Markdown, it is Obsidian-vault compatible, so you can try ZenNotes against an existing vault without converting anything. That compatibility is a smart move: it lowers the cost of trying ZenNotes to almost nothing, since you keep your files regardless of which app you end up using.

Cross-platform desktop and self-hosted web

ZenNotes ships native desktop builds for macOS (both Apple Silicon and Intel), Windows, and Linux, built on Electron. If you would rather run it as a web app, there is a self-hosted option using a Go backend in Docker. What is missing is a hosted cloud mode, which is listed as planned rather than available, and there is no mobile app at all. So while the desktop coverage is broad, your notes do not yet follow you to a phone or a managed cloud.

How Much Does ZenNotes Cost?

ZenNotes is free. The entire app is open source under the MIT license, with no paid plan, no subscription, and no feature gating. Self-hosting the web version costs nothing beyond your own server. The only money involved is an optional GitHub Sponsors donation, which is voluntary and unlocks nothing.

Compared with the rest of the space, that is aggressive. Obsidian is free to use but charges $4/mo for Sync and $8/mo for Publish. Logseq is free with a $5/mo Sync add-on. Joplin is open source and free with an optional Joplin Cloud tier starting around $2.99/mo. ZenNotes simply does not charge, because it has no hosted service to sell yet.

The flip side is what that free model leaves out. With no cloud offering, there is no managed sync to pay for, which is convenient on price but inconvenient if you want effortless cross-device notes. You are trading dollars for doing your own syncing, typically by dropping the vault into a folder backed by iCloud, Dropbox, or Git. For developers that is a non-issue, but it is not the one-click experience a paid sync service gives you, so weigh whether that convenience is worth the few dollars a month a rival would charge.

Who is ZenNotes Best For?

Use ZenNotes if you are a developer or Vim user who wants local-first, plain-text Markdown notes and values keyboard speed over a pretty mobile app. The MCP server makes it especially appealing if you already work with Claude or Codex and want your notes wired into those tools.

Skip ZenNotes if you need seamless cloud sync out of the box or a polished phone app, because neither exists yet. Also think twice if you do not use Vim, since the editing model assumes it. And because this is an early, solo-maintained project moving fast, anyone who needs a stable, mature tool for critical work should wait a few releases.

• Use it if: you want a free, keyboard-first, local Markdown vault with native AI tooling.
• Skip it if: you need built-in sync, a mobile app, or a non-Vim workflow.

Best ZenNotes Alternatives

Obsidian

Obsidian is the polished local-first leader and the most direct comparison, since ZenNotes reads Obsidian vaults. The core app is free, with paid add-ons for Sync ($4/mo billed annually) and Publish ($8/mo). It has a huge plugin ecosystem and mobile apps, which ZenNotes lacks. If you want maturity and cross-device sync now, Obsidian wins.

Logseq

Logseq is a free, open-source outliner and knowledge base that works on plain Markdown or Org files. It is block-based rather than document-based, with a strong graph view and daily-journal workflow. Core features are free, with optional Sync at about $5/mo. It is a better fit if you think in outlines instead of long documents.

Joplin

Joplin is an open-source notes app whose standout is built-in end-to-end encrypted sync, the exact thing ZenNotes is missing. It is free, with optional Joplin Cloud from around $2.99/mo for managed sync, and it has desktop and mobile apps. If sync is non-negotiable, Joplin is the safer open-source choice.

Final Verdict: Is ZenNotes Worth It?

ZenNotes is a strong, opinionated take on developer notes. It is free, fast, MIT-licensed, and genuinely good at keyboard-first Markdown, and the built-in MCP server is a smart, forward-looking touch that most note apps do not have. For Vim users who keep their notes in plain text, it is well worth installing today, especially since it can point straight at an existing Obsidian vault.

The 7.2 rating reflects clear gaps rather than bad execution. No cloud sync and no mobile app are big omissions in 2026, the split-view lag is real, and it is still an early, one-person project with little community around it yet. If those limits are deal-breakers, Obsidian or Joplin will serve you better. The pace of releases is encouraging, though, and the plain-text storage means you risk nothing by trying it.

Our recommendation: if you are a Vim user or a developer who keeps notes in Markdown, point ZenNotes at a copy of your vault and live in it for a week. The keyboard speed and the MCP integration are the kind of features you do not realize you wanted until you have them. If you need your notes on a phone or synced automatically across machines, wait for the cloud mode to ship, or pair it with your own file-sync setup in the meantime. For the right user, this is one of the more exciting free notes tools to appear recently.
