personalized autocomplete

autocomplete that actually knows you — your vocabulary, your writing style, your recurring phrases, your common recipients, your topics, your opinions. the gap with existing autocomplete (even AI-powered ones like Gmail's smart compose) is that they model generic English rather than your specific voice. the result is suggestions that are grammatically fine but feel wrong — too formal, too casual, using words you don't use, suggesting endings that don't reflect how you'd finish the thought.

the technical approach: train or fine-tune a small language model on your corpus — emails sent, messages, documents, notes — so it learns your voice specifically. the model would autocomplete based on both semantic context (what makes sense to say here) and stylistic context (what sounds like you). a local-first approach is essential: your writing is maximally private data. the inference cost needs to be low enough to run on-device so suggestions appear instantly without a round trip to a server.
