How Obsidian fits in an AI stack
In a well-built AI toolkit, Obsidian works as a productivity layer — embedding AI directly into the notes and documents you already keep. Obsidian has a free tier, which makes it a low-risk addition — the main cost is the time it takes to learn.
Before adding it, check what you already pay for: tools in the same category often overlap heavily, and stacking two of them rarely doubles your output. The free Central Hub For AI stack manager can flag overlaps with Obsidian and show what a swap would save.
