ChatGPT and Gemini both have memory features — you can see and delete what they remember. But you see summaries, not structured facts. Thremark shows every mark exactly as it was saved: searchable, editable, deletable. Full control over what it knows. See it, edit it, delete it.
Pure SwiftUI with deep Apple integrations: Siri, Dynamic Island, home screen widgets, Share Extension, Spotlight. Not a WebView wrapper. Not Electron. Built specifically for iPhone. iPad coming soon.
Pick your vibe — Fast for quick answers, Smart when you need reasoning, Full when you want it all. Thremark routes to the right model automatically. One app, multiple AI engines, no manual switching.
