Lightning Notes vs VoiLog

Record. Transcribe. Summarize. All on your device. Transcription and speaker separation run entirely on your iPhone — no audio ever leaves your device. Stop the recording and on-device AI works out who said what, producing a speaker-labeled transcript. Then choose local AI or Cloud AI to write the meeting notes. Supported by ads, with all core features available without a subscription. ------------------------ Key Features ------------------------ ■ Accurate Transcription — On-Device Apple's speech recognition engine processes your audio entirely on-device. Meetings, lectures, interviews — transcribed without sending audio anywhere, and reliable even for long recordings. ■ Automatic Speaker Separation Speaker separation runs automatically on your iPhone once recording stops, identifying who said what across multi-participant conversations. Voice fingerprints are learned over time, so names get assigned automatically in later meetings. Manual editing is always available. ■ AI Meeting Notes — Your Choice of AI · On-device AI: No internet required; nothing leaves your iPhone. Needs 6 GB RAM or more (iPhone 13 Pro and later). · Cloud AI: DeepSeek V4-Flash via OpenRouter, streamed in real time. API data is not used for model training, and only Zero Data Retention (ZDR) endpoints are used, so the provider does not store your data to disk. ■ Speaker Summaries & Person Profiles (Cloud AI) See each participant's role, key points, and behavior in the meeting. Across up to 30 past meetings, AI builds a profile of a person's role, communication style, and projects. ■ Action Items, Extracted (Cloud AI) Cloud AI meeting notes also pull each person's action items into the Tasks tab. Set yourself among your people to see your tasks apart from everyone else's. Each task keeps the line it came from and links back to its meeting; move it from Needs confirmation to In progress to Completed, also right on the meeting's screen. Tasks stay on your device. ■ Dictionary Correction (Custom Terms) Register company names, product names, and jargon, and the app fixes where speech recognition misheard them — "Tower Electric" becomes "Towa Electric". An on-device language model checks each fix reads naturally in context, so unrelated passages are left alone. Fixes can be reviewed, reverted one at a time, and applied to past meetings. ■ Audio & Video File Import Import external audio or video recordings and run them through the same transcription and speaker separation pipeline. ■ Share & Export Export as PDF, choosing which sections to include (summary, speaker summaries, transcript). Speaker colors and tables are preserved. Text and audio sharing are also supported. ■ Privacy-First Architecture Transcription, speaker separation, and local summarization all run on-device. Cloud AI is opt-in — leave it off and no recording content ever leaves your iPhone. ■ Folder Organization Organize meetings into folders by project, client, or topic. ■ Full-Text Search Search titles, summaries, and transcripts. Find any meeting by keyword in seconds. ■ Edit Transcripts Fix recognition errors directly in the app and save an accurate record. ■ Control From the Lock Screen Elapsed time appears on the Lock Screen and Dynamic Island while recording, with pause, resume, and stop right there. Add the Control Center button to start recording without launching the app. ■ Backup & Restore Export meetings, transcripts, and speaker data to a file and restore it on another device or after reinstalling. You keep the file; nothing goes to an external server. ------------------------ Requirements ------------------------ · Transcription, speaker separation, file import: iPhone 12 or later (A14 chip), or iPad with M1 or later · Local AI summarization: 6 GB RAM or more (iPhone 13 Pro, iPhone 14 series, iPhone 15 and later) · Audio/video formats: WAV, M4A, MP3, MP4, and other common formats --- Take back your meetings. No subscription required.

VoiLogは、会議メモから業務利用まで、あらゆる音声を「すぐに使えるテキスト」に変える文字起こしアプリです。 ■ 3つの録音モードで使い分け ・マイク録音：iOS 標準の音声認識を使ってリアルタイムに文字起こし。料金もかからず、思いついたメモをその場で残せます。 ・会議モード：OpenAI の高精度音声認識（Whisper 系）を使い、対面会議や少し離れた声、複数人の会話もしっかり文字化。 ・画面音声録音：Zoom / Microsoft Teams / Google Meet などのオンライン会議の音声を、マイク音声と同時に記録し、まとめて文字起こし。 ■ こんな方におすすめ ・社内会議やお客様との打ち合わせをすぐに議事録化したい ・取材インタビューをテキストに起こす作業を効率化したい ・オンライン会議の発言を後から検索したい ・ひとりブレストや学習メモを音声で残し、あとで読み返したい ■ プライバシー設計 ・録音ファイルと文字起こしテキストは端末内ローカルストレージにのみ保存。当社サーバーには送信されません。 ・会議モード／画面音声録音モードを使う場合は、ご自身の OpenAI API キーを設定画面に登録（BYOK 方式）。料金もユーザー自身が直接 OpenAI に支払う形なので、利用量とコストをご自分でコントロールできます。 ・トラッキングや広告は一切ありません。 ■ OpenAI API キーについて 会議モードと画面音声録音モードは、OpenAI 社の音声認識 API（gpt-4o-mini-transcribe）を使うため、ご自身の API キーが必要です。アプリ内「設定 → API キーの取得方法」で取得手順を解説しています。料金は OpenAI 公表値で約 27 円／時間です（2026年5月時点）。 マイク録音モードのみご利用の場合は、API キーは不要で、すべての機能を無料でお使いいただけます。
