    Our take

    Understanding Obsidian.

    Obsidian is your second brain, stored locally. Free to start, paid plans for more. Built for B2B consultants and writers and newsletter creators.

    Your data stay local (Markdown files), no dependency on a cloud service. free for personal use, no limits, knowledge graph to visualize connections between notes. Very rich community plugins ecosystem. In practice: research and monitoring: connect your reading notes, articles, and ideas in a knowledge graph. Also: long-form writing: write a book, thesis, or series of articles with interconnected notes. Estimated time saving: 3h/month.

    Keep it if: you are a writer/researcher or you want to own your data (Markdown files). Skip it if: you need to collaborate as a team or you hate configuring plugins. Main limit: less intuitive interface than Notion for beginners. As soon as you start writing long-form articles or books.

    Obsidian's billing traps

    Free for personal use, paid for multi-device sync

    The core app has no limits, but syncing notes between desktop and mobile requires Sync at $5/month ($4 annual) — without it, you need a third-party service (iCloud, Dropbox) with its own file-conflict risks.

    Publish is a separate add-on, not included in Sync

    Publishing notes online ($10/month or $8/month annual) is a subscription separate from Sync — both together cost $12-15/month for full usage.

    The AI angle

    Obsidian vs AI

    AI augments this tool
    Go further with AI

    Obsidian benefits from third-party AI plugins (summarization, note-linking generation) built by its community, but remains fundamentally a local linked-notes system — AI adds capabilities, it doesn't change the tool's philosophy.

    Can AI replace it?

    Replace Obsidian with an AI? No: Obsidian's value is keeping notes local, under your control, with bidirectional links built over time — a personal thinking system AI doesn't replace. It can help summarize or link notes. Verdict: AI augments note usage, the thinking system remains personal.
