Lyonesse: AI Transcript & Chat

Record, transcribe and summarize on your device. Ask questions across your notes and PDFs. No account, no uploads, works offline.

Record a meeting or lecture and read the words as people speak. Ask a question about what was said, get a summary in seconds, and find any moment later with search. The transcription and AI run on your device.

Lyonesse is a private workspace for the things you record and the documents you read. Recording, transcription, summaries, speaker labels, and Q&A happen locally. There is no cloud transcription provider, so it keeps working with no internet and your audio is not uploaded to be processed. No account to create. Optional iCloud sync is off by default.

WHAT YOU CAN DO

• Transcribe live recordings, or import an audio or video file you already have. On Mac you can also capture system audio from any app, call, or video playing on your device.
• Get AI summaries in the style you want: concise, bullets, action items, or a structured outline.
• Ask Lyonesse: chat across your whole library. Notes, transcripts, PDFs, and images, with follow-up questions and citations back to the source.
• Read your documents. Import a PDF, Word, Excel, PowerPoint file or an image, then summarize it, pull out the key points, or ask it questions.
• Run a private meeting assistant: link your calendar, see full-screen live captions, get on-device speaker labels, and turn a recording into drafted minutes with action items.

PICK YOUR ENGINE Lyonesse ships Apple Speech and a downloadable Parakeet model for transcription, plus Apple Intelligence and a downloadable Qwen 3 model for on-device AI. Auto picks the best one available for your language and device. In our published LibriSpeech benchmark, Apple's Speech API outperformed the Whisper models Lyonesse used to ship (read it at lyonesse.app/blog/apple-speech-api-benchmark.html).

BUILT FOR STUDY AND WORK

• Turn a recording into study sheets, meeting minutes, or follow-up notes with Smart Drafting.
• Organize notes into Projects that file themselves, then ask questions across a whole project.
• Export to PDF or text with an optional summary, Q&A, and full transcript. Send action items to Apple Reminders.
• Full-text search across recordings, transcripts, documents, and action items.

PRIVATE BY DEFAULT Your recordings, documents, and transcripts stay on your device. Recording, transcription, summaries, speaker labels, document analysis, and Q&A run on-device, with no cloud AI provider in the loop. A private alternative to cloud tools like Otter, Fireflies, Rev, and ChatPDF.

Works on iPhone, iPad, and Mac, with transcription and summaries in 15 languages.

Lyonesse is free to download and there is a free tier. For unlimited use, choose a subscription or a one-time Lifetime purchase. No per-minute fees.
