PREMIUM: YOUR OWN BACKEND AND MCP Includes Standard capabilities and adds a connection to your own Cloudflare Worker backend, backend semantic search, API access and MCP integration for compatible tools such as Claude Code and Cursor. This option requires your own Cloudflare account, deployed backend URL and API key. MCP also requires a bridge and compatible client. Cloudflare usage may incur separate charges. Local-only memories are not automatically available to external assistants. WHERE YOUR DATA GOES Local Only stores memories on this device. iCloud sync transfers them through your personal Apple iCloud account. The optional Cloudflare mode sends memories to your configured backend for storage and selected AI processing. Connected MCP clients handle data according to their own configuration and provider policies. Voice capture uses Apple's speech recognition and may use Apple servers. Microphone and speech recognition permission are required. Location context is optional. The app requests in-app consent for AI processing. AI REQUIREMENTS On-device AI chat uses Apple Foundation Models and requires iOS 26 or later, compatible Apple Intelligence hardware, Apple Intelligence enabled and an available model. Voice capture and ordinary search do not depend on Foundation Models. Premium users can configure cloud AI through their own backend. Check the App Store compatibility section before installing.

External backend services are separate. Developed in Switzerland by Heinrich Krupp. Product facts: https://secondbrain-pro.netlify.app/facts Support: https://secondbrain-pro.netlify.app/support

Verdict
The clearest difference is update cadence: AI Assistant at fortnightly against SecondBrain Pro's every 2 months. AI Assistant also leads on iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
