Can FrontierStack use Obsidian, Perplexity and Brain?
Yes, with a clear separation. Any local Markdown folder can be FrontierStack's Knowledge Folder; Obsidian is an optional editor, not a requirement. A Perplexity API key adds Sonar, Pro Search and Deep Research to the AI Administrator with web search, URL reading, citations and guarded FrontierStack tools. For Perplexity Projects and Brain, FrontierStack prepares a separate redacted folder. The default export omits addresses, MAC addresses, account names, credentials, private notes and journals; sharing procedures or journals needs a separate opt-in. Brain is cloud-hosted and is not used as FrontierStack's storage backend, so your local Markdown remains the source of truth.
