# **Honest comparisons, including where we lose **

Treehouse is a shared workspace of plain files for people and their agents. It suits some teams better than the tools below, and some teams worse. Each page says which.

## **Comparisons**

- [

  Obsidian for teams

  **Obsidian**

  Treehouse syncs a plain folder, so your vault can be a shared workspace for your team and agents. Here's what works today, what doesn't, and what it costs.

  Notion and AI agents

  **Notion**

  Agents work on a Treehouse folder at local speed, and every change reaches your team. Here's how that compares with Notion, and where Notion is better.

  Fastio alternative

  **Fastio**

  Both give people and agents a shared workspace. Fastio offers more storage and built-in AI. Treehouse offers a free plan, safer writes and one-step undo.

  **Obsidian and Claude Code for teams**

  Claude Code works well in an Obsidian vault. Doing it as a team is harder. Share the vault, see what Claude changed, and undo it when it goes wrong.
