Projelli vs Obsidian

Side-by-side

The real distinction

Obsidian's core promise is that it ships an editor, and the community ships everything else. That's a genuinely good architecture for a personal knowledge base, and it's why Obsidian has grown for years without a single feature that the community couldn't build. But the cost of that architecture is consistency. Smart Connections passed 786,000 community downloads by January 2026 and its stats are on obsidian-stats, which is impressive, but it's still a plugin maintained by one developer that can break with any Obsidian core update. The Copilot for Obsidian plugin reaches 100,000+ users and ships weekly, which is also impressive, but it's a separate codebase with a separate release cycle.

Projelli takes the opposite bet. One polished app, three providers built in, the AI is the primary input method, and every chat conversation produces a real Markdown file in your folder. Where Obsidian's AI plugins treat AI as an enhancement to writing, Projelli treats the conversation as the first draft. You can still edit the file by hand afterward, the same way you would in Obsidian. The difference is in what starts the document.

The second distinction is founder templates. Obsidian has a thriving community templates ecosystem, but the good ones (Linking Your Thinking, PARA, various zettelkasten kits) are for personal knowledge work. There is no "run an interview, produce a Pitch Deck outline, save it as PITCH_DECK.md" flow anywhere in the Obsidian ecosystem. Projelli ships 15 of those, one per specific founder document type. See the gallery for what each one actually produces.

The third distinction is the MCP server. Projelli's workspace is exposable to Claude Desktop, Cursor, Zed, and any other MCP-compatible client via a one-click .mcpb install. Obsidian does not ship a first-party MCP server; community projects approximate it but none are production-ready as of April 2026.

When to pick Projelli

• You want a local-first AI workspace but you've never been willing to spend a weekend assembling Obsidian plugins.
• You're an indie founder who writes the same 15 kinds of documents and wants templates for each.
• You want chat conversations saved as files automatically, not as ephemeral UI state.
• You want Claude, OpenAI, Gemini, and Ollama all in one app without four plugins.
• You want your workspace available to Claude Desktop, Cursor, or Zed via MCP out of the box.

When to pick Obsidian

• You already have a working Obsidian vault with plugins you trust, and you're editing daily.
• You want to model a second brain with a rich plugin ecosystem (dataview, tasks, graph view, canvas).
• You want a free tool forever with a paid sync add-on, not a one-time purchase.
• You need mobile sync today. Obsidian has first-party iOS and Android apps; Projelli is desktop-only.
• You're happy to assemble your own AI stack from community plugins and prefer that flexibility.

The honest caveat

Obsidian's community could ship a "Founder Workflows" plugin this weekend that closes most of the gap between them and Projelli. That's the nature of its architecture. Projelli's bet is that a polished, single-developer product with AI as the primary input beats an assemble-it-yourself plugin stack for the specific audience of indie founders trying to ship a business on weekends, even if a community plugin eventually approximates the feature set. If you're a power user who enjoys assembling your own stack, Obsidian remains the right call.
