Your notes stay in your folder.
Choose an existing folder of Markdown files, including one with an Obsidian-compatible structure. SideBrain searches notes locally and opens results read-only in Brain Explorer. This is available on macOS 0.76.0; Windows 0.72.3 does not support Vault search or reading. SideBrain is an independent product.
Choose a folder, find notes, decide what comes next
Select a Vault
In settings, choose an existing Markdown folder with write access. No account, AI key or separate server is needed.
Search and read locally
Brain Explorer finds titles, tags and text with a local index. You can read notes; SideBrain does not change them. The view is read-only.
Gbrain is a separate choice
If you want to keep notes in a Gbrain later, you can import them in a separate, one-time step. The source files stay unchanged.
Capture notes cannot be pushed into a Vault. SideBrain does not sync Vault files between devices. Set up a Vault and read the details · Import notes into a Gbrain once.
Start with the folder you already use.
Choose a Markdown folder and search it in Brain Explorer — no AI key required.
