About this app
Turn your phone into a secure, offline "Second Brain."
Refine is the ultimate AI-powered note-taking workspace designed for students, professionals, and writers who value privacy and productivity. Unlike other AI tools that send your data to the cloud, Refine runs a powerful Large Language Model (LLM) entirely on your device.
Capture meetings, lectures, and fleeting ideas instantly. Let AI handle the heavy lifting of transcribing, summarizing, and polishing your text—even in Airplane mode.
🚀 KEY FEATURES
🎙️ Offline Speech-to-Text (STT) Forget about internet connection limits. Refine uses the advanced Sherpa-ONNX engine to convert voice recordings into text with high precision and zero latency. Perfect for journalists, students, and meeting minutes.
✨ AI Grammar & Style Polish Write with confidence. Refine acts as your personal editor. With one tap, our integrated AI scans your notes to correct grammar mistakes, fix punctuation, and rewrite awkward sentences into professional, clear English.
🧠 Smart AI Summarization Don't have time to listen to an hour-long recording? Let Refine's on-device AI (Gemma) analyze your notes and generate concise summaries, bullet points, and key takeaways in seconds.
🔒 100% Privacy First Your thoughts are yours alone. Refine is built with a "Privacy-by-Design" architecture.
No cloud servers.
No data tracking.
No monthly subscriptions for privacy. All audio processing and AI generation happen locally on your phone’s hardware.
📂 Organize Your Life
Create color-coded folders for Work, School, or Personal ideas.
Manage unlimited notes with a clean, distraction-free interface.
