ThinkAudio - AI Voice Recorder

Your voice. Your AI. Your privacy. Record, transcribe on-device, and get instant AI-powered insights — all without your data ever leaving your iPhone.

ThinkAudio is an AI-powered voice recording and analysis app designed to supercharge your thinking. It combines on-device speech recognition with intelligent LLM analysis, turning every conversation, meeting, and idea into structured insights and actionable outcomes.

HOW IT WORKS

1. Record — Tap to start. Real-time audio waveform visualization shows every word as it happens.
2. Transcribe — On-device speech recognition converts your audio to text instantly, privately, right on your iPhone.
3. Analyse — Choose a scene and let AI generate a structured Markdown report tailored to your context.
4. Review — Everything is saved to your personal library: recordings, transcripts, and AI results, all in one place.

BUILT-IN ANALYSIS SCENES

• Meeting — Summaries, key decisions, and action items extracted automatically.
• Todo — Tasks and priorities pulled directly from your voice notes.
• Memo — Quick notes organised and structured for easy reference.
• Interview — Q&A structuring and key insight extraction.
• Summary — Concise digest of any recorded content.

Create your own custom scenes with a personalised System Prompt to match any workflow or domain.

PRIVACY FIRST

ThinkAudio is built on a single principle: your data never leaves your device without your explicit control.

• Speech recognition runs 100% on-device — no audio is ever sent to any server.
• Bring your own LLM: connect any OpenAI-compatible API (OpenAI, Anthropic, local Ollama, or any custom endpoint). You choose which AI sees your transcripts.
• All recordings, transcripts, and results are stored locally using SwiftData.
• Zero tracking. Zero analytics. No ads.

TECH HIGHLIGHTS

• Native SwiftUI — fluid, responsive, and battery-efficient.
• SwiftData persistence — fast, reliable offline access to all your recordings.
• Supports any OpenAI-compatible API endpoint for maximum flexibility.
• Clean Markdown rendering for AI analysis results.

Whether you're a professional capturing meeting minutes, a student summarising lectures, a researcher conducting interviews, or anyone who thinks better by talking — ThinkAudio gives you the clarity you need.

Turn every sound into clear thinking.
