Noda — AI Business Meeting Dictaphone Stop typing meeting notes. Press record, speak naturally, and Noda's AI turns every conversation into a clean, structured protocol — with action items, decisions, and key points already separated. Available in six languages, with multi-format export and a built-in Q&A chat that lets you ask the meeting itself. AI MEETING TRANSCRIPTION - One-tap recording, up to 60 minutes per session - Local-first: recording continues even if your network drops, queued uploads survive force-quit and reboot - Transcription powered by Google Gemini Flash - Multi-speaker speech recognition AI PROTOCOL GENERATION After the recording, tap Generate Protocol and the AI produces a structured memo: - Title and key discussion points - Decisions and agreements (numbered) - Action items with assignees and deadlines - Sentiment summary Powered by Gemini Pro, with explicit anti-verbatim rules — you get a real protocol, not a transcript dump. DOCUMENT CONTEXT Upload up to 5 files (PDF, DOCX, XLSX) before the meeting and the AI will incorporate their content into the protocol. Useful for agendas, contracts, and previous-meeting follow-ups. INFOGRAPHICS Generate a single-image visual summary of the meeting in your brand style — perfect for email follow-ups or Slack updates. AUDIO RECAP (TEXT-TO-SPEECH) Turn the protocol into a podcast-style audio recap with one or two AI voices. Listen on the way home from the office. ASK THE MEETING A built-in chat with the meeting itself — ask follow-up questions like "who was responsible for the rollout date" or "summarize the budget discussion" and get answers based on the actual transcript. MULTI-FORMAT EXPORT Export as PDF, Markdown, plain text, or styled HTML5. All formats include UTF-8 BOM so Cyrillic and CJK render correctly in Notepad and legacy viewers. Share with one tap to WhatsApp, Telegram, email, or Save to Files. BRAND STYLE PRO users can set company name, brand colors, and upload a logo. The styling flows into HTML exports and infographics automatically. MEETING HISTORY All your meetings live in one timeline with TTL-based cleanup so storage stays manageable. Tap to reopen, regenerate, or chat with any previous meeting. SPEAKS YOUR LANGUAGE UI and AI generation in English, Russian, Chinese, Japanese, German, and Spanish. AI responses follow the language you choose for the protocol — independent of the device language. CLEAN, FOCUSED DESIGN Modern OLED-dark theme. No clutter, no ads, no social feed — just the tools you need to capture decisions and follow through. — SUBSCRIPTION & COIN SYSTEM — Free tier: 15 coins on registration to try out the AI features.
