Hey everyone,

I’ve been building Cognote, an iOS app focused on private, on-device transcription and knowledge synthesis. My goal is to keep the entire pipeline local—no cloud, no API calls for the core reasoning—to ensure complete privacy while still delivering a fast, useful AI assistant.

I’m currently in the TestFlight phase and am looking for feedback from developers and power users who care about privacy and on-device performance.

What I’m specifically looking to validate right now:

* Inference Performance: How is the model holding up for you during real-time transcription? Any issues with RAM management or device heat on older vs. newer models?

* UI/UX: I’m aiming for a 'Liquid Glass' aesthetic with fluid, organic animations. Does the interface feel responsive, or does it feel like the heavy AI lifting is causing UI jank?

* Privacy Workflow: Does the 'local-only' setup feel transparent and intuitive?

Tech Stack: Swift, SwiftUI, Core ML (local LLM inference).

I’m really looking for candid, actionable feedback—if you find a bug, break it, or see a way the architecture could be cleaner, please let me know. I'm all ears.
