I put Gemma 4 E4B and E2B into an e-reader so I can ask my weird questions and share my thoughts in private directly in app.

Here's how it works in the app:

• Framework: Runs on LiteRT-LM (like Google's AI Edge).
• Models: Downloads either the E2B (~2.5 GB) or E4B (~3.6 GB) INT4 quantized models directly from ungated litert-community repos without API keys, tokens, or accounts.
• Execution & Memory: Defaults to GPU execution with a CPU fallback. To preserve RAM, the model only initializes into memory while the AI chat UI is active and unloads when closed.
• Context Pipeline: Book's metadata and current passage position is automatically injected so it provides accurate answers without user prompt engineering.
• Features: Includes a Deep Think toggle (trades speed for context depth), a Spoilers toggle to prevent plot leaks in story books and automatic response language matching based on the selection.
• Other stuff: You can save responses and add them to the note & highlight system.

The app is not just AI, it's a full-featured e-reader. More details here: https://gardenreads.app/

I'd love your feedback on this!
