# Matzu London demonstration — English transcript 95.966667-second demonstration (1 minute 36 seconds when rounded). Full V10 picture with the Carefree soundtrack. Edited app recordings with dubbed and recreated audio. ## What is recorded and what is recreated The app footage comes from separate founder planning, London field and restaurant sessions, not one continuous trip or device test. The prepared planning example has six stops; the separate London field session has ten. The planning recording is from Android; the separate downloadable Paris screenshots show iPhone. Capture builds are not verified here. Waiting time is shortened. The walking approach is real GPS movement shown at 21× speed, followed by the original arrival at normal speed. The Tower Bridge detail card is opened manually; its original scrolling is edited to remove pauses and reverse movements. No automated detail-card opening is claimed. The original London field recording is silent. Traveller and editorial voices are dubbed. The flexible planning and restaurant requests are demonstration scripts, not recovered verbatim speech from the source recordings. The restaurant reply is also scripted dubbing over real app footage. The footage shows The Ivy Asia being added, its detail card and the restaurant website; it does not show a completed reservation or establish that the dubbed exchange was captured live. Recorded website offers and prices are not a Matzu offer or a guarantee of current availability. The arrival excerpt is recreated from Matzu's production narration prompt, not recovered London sound. The Tower Bridge question and follow-up were submitted as text to an external native-audio session using Matzu's released base prompt, Short mode and Aoede voice. Its answers were generated by the model, not written by the video editor. Unlike the scripted restaurant dubbing, this is a model-generated conversation. It was recorded outside the phone app, without app tools, GPS, itinerary state or microphone transcription; it proves none of those behaviours or phone latency. The video labels it as a recreated conversation. The offered bridge-opening schedule lookup is not shown as performed. The bridge dialogue uses a real founder photo from 2019 as contextual imagery, not a frame from the 2026 walk. The original Matzu logo/signature close is preserved. No unlimited free use or offline live conversation is depicted. ## Chapters These seek times mark the starts of the title cards, before each spoken chapter name. | Start | Chapter | |---|---| | 00:00:00.000 | Introduction | | 00:00:04.000 | Plan your day | | 00:00:27.800 | Walk & listen | | 00:00:42.600 | Ask anything | | 00:01:08.100 | Change your plans | | 00:01:31.467 | Matzu close | ## Spoken soundtrack ### 00:00:00.300–00:00:03.580 · Voiceover Matzu.
