Lightning Notes - AI Recorder

Transcription and speaker separation happen on your iPhone — no audio sent to the cloud. On-device AI or Cloud AI for meeting notes. Learns your speakers over time.

Record. Transcribe. Summarize. All on your device. Supported by ads — all core features are available without a subscription.

Transcription and speaker separation run entirely on your iPhone — no audio ever leaves your device. After recording stops, on-device AI identifies who said what and generates speaker-labeled transcripts. Then choose local AI or Cloud AI to create meeting notes. No subscription. No monthly fee.

Key Features

■ Accurate Transcription — On-Device After recording, Apple's speech recognition engine processes your audio entirely on-device. Meetings, lectures, interviews — all transcribed without sending audio to any server. Works reliably even for long recordings, without network dependency.

■ Automatic Speaker Separation Once recording stops, speaker separation runs automatically on your iPhone. The app identifies who said what across multi-participant conversations. Speaker fingerprints are learned over time — in future meetings, names are assigned automatically. You can also edit speaker names manually.

■ AI Meeting Notes — Your Choice of AI Two summarization options: · On-device AI (Local): No internet required. Audio and transcripts never leave your iPhone. Supported on devices with 6 GB RAM or more (iPhone 13 Pro and later). · Cloud AI: High-quality meeting notes using DeepSeek V4-Flash via OpenRouter. Streams results in real time. Does not use API data for model training. Zero Data Retention (ZDR) endpoints only — the provider does not store your data to disk.

■ Per-Speaker Summary (Cloud AI) Cloud AI generates a breakdown for each participant: role, key points raised, and behavior during the meeting. See who drove decisions and who needs follow-up.

■ Person Profiles (Cloud AI) Build a knowledge base of the people you meet. The app cross-references up to 30 past meetings featuring a person, then generates an AI profile of their role, communication style, and project involvement.

■ Audio & Video File Import Import external recordings — audio or video — and process them through the same transcription and speaker separation pipeline.

■ Share & Export Export meeting notes as a PDF — choose which sections to include (summary, speaker summaries, transcript). Speaker colors and formatted tables are preserved in the PDF. Text and audio sharing are also supported.

■ Privacy-First Architecture Transcription, speaker separation, and local AI summarization run entirely on-device. Cloud AI is opt-in — if you don't use it, no recording content ever leaves your iPhone.

■ Folder Organization Organize meetings into folders by project, client, or topic for fast retrieval.

■ Full-Text Search Search across titles, summaries, and transcripts. Find any meeting by keyword in seconds.

■ Edit Transcripts Correct any recognition errors directly in the app and save an accurate record.

■ Meeting Types · Meeting: Multi-participant discussions · Lecture / Seminar: One-to-many presentations or classes · Interview: One-on-one or small group conversations
