Tolaria – Open-source macOS app to manage Markdown knowledge bases

Hey there! I am Luca, I write https://refactoring.fm/ and I built Tolaria for myself to manage my own knowledge base (10K notes, 300+ articles written in over 6 years of newslettering) and work well with AI.Tolaria is offline-first, file-based, has first-class support for git, and has strong opinions about how you should organize notes (types, relationships, etc).Let me know your thoughts!

Open-source macOS markdown note app targeting writers and researchers who want offline-first knowledge management with git integration.

The pain

Knowledge workers accumulate thousands of notes across tools (Obsidian, Notion, Apple Notes) but struggle with: organizing relationships between ideas, maintaining version history, working offline reliably, and preparing notes for AI processing without vendor lock-in.

The gap

Existing tools are either closed-source SaaS (Notion), require subscriptions (Obsidian Sync), or lack strong opinions about structure. Writers with large note collections need something that treats git as a first-class citizen and enforces consistent schemas for AI compatibility.

Build angle

Start by deeply serving the 'serious writer with 5K+ notes' segment (newsletter writers, researchers, academics). Charge for premium features (cloud sync, AI integration, publishing tools) while keeping core open-source. Validate willingness to pay before building the full feature set.

Strengths

  • Founder has proven use case (10K notes, 6 years of content) - not theoretical
  • Offline-first + git approach solves real pain points competitors ignore
  • Open-source positioning builds trust with technical audience
  • macOS-first focus allows deep OS integration rather than spreading thin
  • AI-native design (structured notes) is timely and differentiating

Risks

  • Crowded market (Obsidian, Logseq, Roam, Apple Notes) with entrenched users - switching costs are high
  • macOS-only severely limits addressable market; Windows/Linux users are excluded
  • Open-source + free model makes monetization unclear; most competitors struggle here
  • Requires users to understand git and markdown - narrows audience to technical writers only
  • No evidence of product-market fit beyond founder's personal use; one user (himself) is not validation
  • AI integration angle is crowded; unclear what specific AI workflow Tolaria solves better
