10 AI Features to Add to Your Flutter App (With Gemini)
10 practical AI features for your Flutter app — chatbot with memory, semantic search, photo analysis, voice, RAG, structured extraction, function calling, image generation, streaming, and smart replies — each with the Gemini API behind it and a deep-dive link.
TL;DR: You don't need a research lab to ship AI features — the Gemini API plus a few Flutter patterns covers enormous ground. Below are 10 features ordered roughly by effort-to-impact: an in-app chatbot with memory, semantic search over your content, photo analysis, voice input/output, RAG over your own documents, structured data extraction, function calling (AI that takes actions), AI image generation, streaming responses, and smart replies. Each one links to a full implementation guide. What you'll learn 10 concrete AI features, from afternoon projects to week-long builds Which Gemini capability powers each one The one architectural rule that keeps your API key (and bill) safe The one rule before you start Never ship your Gemini API key in the app. Every feature below should call Gemini through your own backend — a Supabase Edge Function is the natural fit — so the key stays server-side and you can rate-limit per user. Read the secure API key proxy guide first; it takes an hour and saves you from every other mistake on this list. 1. In-app chatbot with memory The classic, and still the highest-impact: a support or companion chat inside your app that remembers the conversation. The trick isn't the chat UI — it's memory : store conversation history in Supabase, feed the recent turns back as context, and summarize older turns when the context window fills.

Embeddings fix it: convert your articles, products, or help docs to vectors once, convert the query to a vector at search time, and return the nearest neighbors. "How do I get a refund?" matches "return policy" without…
