ThinkAloud

Think out loud. ThinkAloud does the rest.
ThinkAloud turns your spoken thoughts into clean, organized, interconnected notes — using AI that runs entirely on your device. No cloud, no accounts, no data leaving your phone. Just speak, and watch your ideas become structured Markdown notes that link themselves together.
🎙️ Voice-first capture
Tap, talk, done. Record a thought and ThinkAloud's AI drafts a polished note from your voice. You can also capture from images or plain text — whatever's fastest in the moment.
🔒 100% on-device & private
The intelligence engine runs a foundational AI model locally on your device. Your recordings, notes, and ideas never touch a server. Absolute privacy by design — works fully offline.
🧠 AI that organizes for you
Every capture is automatically:
• Drafted from raw audio, image, or text
• Polished into clean, readable Markdown
• Auto-tagged with consistent, canonical tags
• Linked to related notes with wikilinks
• Checked for duplicates so your vault stays tidy
🔗 A knowledge graph that grows with you
ThinkAloud finds connections between your notes using on-device semantic search and weaves them together with wikilinks. Explore your thinking visually in an interactive knowledge graph.
💬 Ask your notes
Chat with your own knowledge base. Ask questions in natural language and get answers grounded in your notes — powered by on-device semantic retrieval (RAG). Your second brain, finally searchable by meaning, not just keywords.
📁 Your notes, your files
ThinkAloud stores everything as plain Markdown with YAML frontmatter in a local vault you own — Obsidian-friendly and future-proof. No proprietary lock-in. Use templates to keep your notes consistent.
📤 Export & share
Export notes to PDF or share them anywhere with a tap.
