Context-Aware SMS Notification Filter That Reads What the Message Means, Not Just Who Sent It
Android users with high-volume contacts (parents, group chats, work) want their phone to suppress notifications based on message content, not just sender. Current filters are keyword and sender based. The unmet need is a small local LLM that classifies 'urgent vs venting' and only buzzes the wrist when a message actually demands a response.
Single request volume but the wedge is sharp... this is the kind of demo that goes viral on r/android the moment somebody posts a screen recording of their phone correctly ignoring mom's weather rant. Keep it 100% on-device with Gemini Nano on Pixel and MLC fallback elsewhere... privacy is the marketing pitch and the technical advantage. $4.99 one-time.

Notification filtering has been a sender-and-keyword problem for 15 years. On-device LLMs (Gemini Nano, MLC) make semantic filtering finally cheap enough to run on every text.
