+ In Music search the CURRENT song with its artist. Tap a search field, type the query, then enter. To replace existing query text, focus field, selectAll, then typeText. Strings are limited to 32 ASCII characters; use multiple typeText steps if needed. Stop if required text cannot be entered.

+ Hold the correct song row to open its menu. Choose Add to a Playlist. For the first song choose New Playlist, type the exact destination name, and save. For later songs select that same playlist. Never create a duplicate playlist.
+ After observing that the add operation succeeded, use songAdded. This advances to the next song but does not verify success. If unsure whether an add was accepted, inspect the destination first, do not add it again.
+ In verifying phase, navigate Library, Playlists, and the exact destination. Use verifyPlaylist when its name, song titles and artists are visible. Scroll if more verification is needed.
+ Tap and hold must reference a current text element ID. Never guess element IDs. Home and spotlight are system gestures. ScrollDown scrolls content upward to reveal lower rows.

+# Playlist Move
+
+Copy a small Spotify playlist into Apple Music using the apps on your iPhone. Built with cell-use, Apple's on-device Foundation Models, and Vision text recognition.
+
+The model reads the current screen's text and chooses the next action. cell-use delivers taps, gestures, text and keyboard commands. The app keeps a song inventory and checks the destination playlist before reporting completion.
+
+## Build
+
+On macOS with Xcode 27 and the tools listed in the repository's setup guide:
+
+```sh
+bash Scripts/build-macos.sh PlaylistMove
+```
+
+The unsigned archive is `.build/playlist-move-unsigned.ipa`. The `Build Playlist Move` GitHub workflow produces the same archive. Sign it for your iPhone before installation.
+
+## Run
+
+1. Enable Apple Intelligence and finish its model download. Sign in to Spotify and Apple Music, with an active Apple Music subscription.
+2. Enable Developer Mode and the local tunnel used by cell-use. Pair Playlist Move through the app's Connection setup section, then connect to this iPhone.
+3. Open a small Spotify playlist in portrait. Return to Playlist Move and enter its exact name, a new destination name, and one or five songs.
+4. Tap **Move my playlist**, wait for **Ready**, then switch back to Spotify. Leave the screen unlocked. The app reads the playlist, navigates to Music, and works through the transfer.
+5. Return to Playlist Move to inspect the result and export its timeline. Returning during a run stops further input. Use a new destination name for a fresh run.
+
+The first device run should use one song. The transfer has a ten-minute time budget and bounded action counts. It stops for an uncertain match or an unsupported interaction. A stopped transfer can leave a partly created destination playlist; inspect it before starting again.
+
+## Recording
+
+Film the physical iPhone with a second camera. Show the start, then keep your hands away during the transfer. This also captures app transitions and the background-task indicator.
+
+Try iOS Screen Recording for a clean second angle. Start recording before starting the transfer, and check a short run first. Some capture and mirroring combinations are restricted by iOS. Music playback is unnecessary.
+
+The exported JSON includes model-decision timestamps, inference durations, transport acknowledgements and the final inventory. Decision timestamps describe when an action was chosen; the runner records when input was accepted. Use these to align captions with footage. Label sped-up sections and keep the original recording.
+
+Suggested edit: show the Spotify playlist, start Playlist Move, show the app transition and first match, speed up the remaining work, then show the completed Apple Music playlist and play one track manually after the transfer has ended.
+
+Inference and text recognition run on the phone. The music apps use their normal internet connections. Exporting a timeline is an explicit share action; it contains playlist and song names, but no screenshot files or pairing secrets.
+
+## Development
+
+```sh
+swift test --package-path Examples/PlaylistMove
+```
+
+`PlaylistMoveCore` contains the inventory, verification rules and grounded actions. `LocalPlaylistAgent` implements `PhoneAgent`; another local model can replace it without changing the transport. The example uses text elements from Vision, rather than sending screenshots to a vision-language model.

Start with one song. If you stop a run, inspect the destination playlist before starting another.
## Recording
-Film the physical iPhone with a second camera. Show the start, then keep your hands away during the transfer. This also captures app transitions and the background-task indicator.
-
-Try iOS Screen Recording for a clean second angle. Start recording before starting the transfer, and check a short run first. Some capture and mirroring combinations are restricted by iOS. Music playback is unnecessary.
+Use iPhone Screen Recording for the whole demo. Start before speaking your request. Check a short take to confirm microphone audio alongside voice input. Narration can be recorded afterward. Music playback is unnecessary.
The exported JSON includes model-decision timestamps, inference durations, transport acknowledgements and the final inventory. Decision timestamps describe when an action was chosen; the runner records when input was accepted. Use these to align captions with footage. Label sped-up sections and keep the original recording.
-Suggested edit: show the Spotify playlist, start Playlist Move, show the app transition and first match, speed up the remaining work, then show the completed Apple Music playlist and play one track manually after the transfer has ended.
+See [the demo script](demo-script.md) for the shot sequence and narration. Keep the first interaction at normal speed, then label sped-up sections while the remaining tracks move.
Inference and text recognition run on the phone. The music apps use their normal internet connections. Exporting a timeline is an explicit share action; it contains playlist and song names, but no screenshot files or pairing secrets.
+Voice recordings are temporary files deleted after transcription or cancellation. Voice input only fills editable fields; it never starts a transfer. The microphone is released before Spotify opens.

+# Playlist Move demo
+
+## The hook
+
+> What if your iPhone could do the tapping?
+
+Show the actual phone doing the work before explaining the SDK. Target a 45 to 60 second edit from one continuous screen recording. Let the successful run determine the edit length.
+
+## Before recording
+
+- Install and pair Playlist Move, connect, and finish the Apple Intelligence and speech model downloads.
+- Complete a one-song transfer before the five-song take. Use a small playlist with clear track titles and artists.
+- Choose a fresh destination name for this take. Keep a copy of the source playlist link ready to paste after voice input.
+- Use Focus to silence unrelated notifications. Keep the phone in portrait and the screen awake. Leave music playback off.
+- Try a short screen recording with its microphone on while speaking to the app. Play it back to check audio. If microphone sharing interferes, record with the screen recorder's microphone off and add narration afterward.
+
+## Shot sequence
+
+| Approximate edit time | Screen | Spoken line or caption |
+| --- | --- | --- |
+| 0 to 3 seconds | A short glimpse of a real automatic tap, then the app | **What if your iPhone could do the tapping?** |
+| 3 to 12 seconds | Tap Say your request, speak, then Use recording | **Copy five songs from my Late Night Spotify playlist to Apple Music. Name the new playlist Night Shift.** |
+| 12 to 17 seconds | Transcript and filled transfer fields. Paste source link if using one, then tap Move my playlist | **One request. Two music apps.** |
+| 17 to 25 seconds | Spotify opens. Show the playlist and the first real navigation steps | **The model reads the screen. cell-use handles the taps.** |
+| 25 to 42 seconds | Music opens, track search, matching result, Add to Playlist | **Running on this iPhone.** Label any time compression with the actual playback multiplier. |
+| 42 to 50 seconds | Destination playlist with copied tracks; show the app's checked result after the run ends | **Same soundtrack. New app.** |
+| 50 to 58 seconds | End card | **cell-use. Build agents that use iPhone apps, from the iPhone.** Then **github.com/Raynan00/cell-use** |
+
+The opening glimpse is a preview from the same successful recording. Use a visible cut back to the beginning. Do not insert a finished playlist from a different run.
+
+## Narration option
+
+> What if your iPhone could do the tapping?
+>
+> I asked it to move five songs from Spotify to Apple Music.
+>
+> It reads the playlist, switches apps, finds the tracks, and adds them.
+>
+> The model runs on the phone. cell-use gives it the controls: screenshots, taps, swipes, and typing.
+>
+> This is Playlist Move, one app built with cell-use.
+>
+> What would you build?
+
+Use the result lines once that take actually completes. Show a full search-and-add interaction at normal speed so people can see how it works, then accelerate the repetitive steps. Keep the original recording and exported timeline.
+
+## Recording notes
+
+The music apps need their normal internet connections. Local AI refers to speech transcription, screen text recognition, and model inference. A screen recording is sufficient; a second camera is optional.
+
+The demo shows a developer SDK operating app interfaces. Playlist transfer is the example task. Keep the launch copy focused on what developers can build with cell-use.
+
+## Post text
+
+> I built an iPhone app that moves songs from Spotify to Apple Music by using the apps on screen.
+>
+> Voice request in. Taps, swipes, and typing out.
+>
+> The AI runs on the iPhone. Built with cell-use, my open-source toolkit for agents that use iPhone apps.
+>
+> github.com/Raynan00/cell-use
+
+Publish with the completed device demo.

# Playlist Move demo
+## Screenshot concept: Comment Section
+
+Proposed next demo flow: import a screenshot of song recommendations, review the extracted track list, then build a Spotify playlist through its interface. This flow needs screenshot import and a Spotify destination added to the app.
+
+> The best song recommendations are buried in the comments. I wanted them in a playlist.
+
+Show a real TikTok comment screenshot with three clear song recommendations. Import it into the app and say:
+
+> Make this a Spotify playlist called Comment Section.
+
+Show the extracted titles and artists for review. Start the run, then show Spotify opening, a complete search-and-add interaction, and the remaining songs being added. End on the finished playlist.
+
+> A screenshot became a playlist. The AI ran on my iPhone, and cell-use did the tapping.
+>
+> What would you build?
+
+Keep the screenshot visible long enough to read the recommendations. Crop unrelated comments and identifying details before recording. Resolve unclear titles or missing artists in the review step. Show the actual result from the recorded run.

+5. Open a readable screenshot in Photos and say **Siri, playlist this**. Playlist Move opens, extracts up to five explicit title-and-artist recommendations, connects to the paired phone, and shows a three-second Cancel countdown. Spotify then opens and the agent creates the playlist.

+Use iPhone Screen Recording for the whole demo, or film the phone with another camera to show your hands away during the actions. Check a short take to confirm Siri and microphone audio alongside screen recording. Narration can be recorded afterward. Music playback is unnecessary.
The exported JSON includes model-decision timestamps, inference durations, transport acknowledgements and the final inventory. Decision timestamps describe when an action was chosen; the runner records when input was accepted. Use these to align captions with footage. Label sped-up sections and keep the original recording.
See [the demo script](demo-script.md) for the shot sequence and narration. Keep the first interaction at normal speed, then label sped-up sections while the remaining tracks move.

+Playlist inference and text recognition run on the phone. Siri handles the voice trigger using the user's system configuration; the music apps use their normal internet connections. Exporting a timeline is an explicit share action; it contains playlist and song names, but no screenshot files or pairing secrets.
Voice recordings are temporary files deleted after transcription or cancellation. Voice input only fills editable fields; it never starts a transfer. The microphone is released before Spotify opens.

+Use iPhone Screen Recording for readable close-ups, or film the phone with another camera to show your hands away during the actions. Record narration afterward or on the second camera. If using the optional Siri shortcut, test its audio alongside screen recording before the take. Music playback is unnecessary.
The exported JSON includes model-decision timestamps, inference durations, transport acknowledgements and the final inventory. Decision timestamps describe when an action was chosen; the runner records when input was accepted. Use these to align captions with footage. Label sped-up sections and keep the original recording.
See [the demo script](demo-script.md) for the shot sequence and narration. Keep the first interaction at normal speed, then label sped-up sections while the remaining tracks move.
-Playlist inference and text recognition run on the phone. Siri handles the voice trigger using the user's system configuration; the music apps use their normal internet connections. Exporting a timeline is an explicit share action; it contains playlist and song names, but no screenshot files or pairing secrets.
+Playlist inference and text recognition run on the phone. The music apps use their normal internet connections. The optional Photos shortcut uses Siri for activation. Exporting a timeline is an explicit share action; it contains playlist and song names, but no screenshot files or pairing secrets.
Voice recordings are temporary files deleted after transcription or cancellation. Voice input only fills editable fields; it never starts a transfer. The microphone is released before Spotify opens.

- Use songAdded only after observing that the add succeeded. If uncertain, inspect the destination to avoid adding twice.

Adapt when a control or expected screen is missing. Retry a better query or another navigation route rather than repeating a failed action.

`PlaylistMoveCore` contains the inventory, verification rules and grounded actions. `LocalPlaylistAgent` implements `PhoneAgent`; another local model can replace it without changing the transport. The example uses text elements from Vision, rather than sending screenshots to a vision-language model.
+
+Each observation supplies a fresh action menu. Tap and hold choices carry their visible target labels, so the model selects an action and target together. The report records that choice and label alongside its observation ID.

- In Music search the CURRENT song with its artist. Tap a search field, type the query, then enter. To replace existing query text, focus field, selectAll, then typeText. Strings are limited to 32 ASCII characters; use multiple typeText steps if needed. Stop if required text cannot be entered.
- Match the same recording, artist and version. Do not substitute a live recording, remix, cover or different clean/explicit version. If unsure, needHelp.
- Hold the correct song row to open its menu. Choose Add to a Playlist. For the first song choose New Playlist, type the exact destination name, and save. For later songs select that same playlist. Never create a duplicate playlist.
- After observing that the add operation succeeded, use songAdded. This advances to the next song but does not verify success. If unsure whether an add was accepted, inspect the destination first, do not add it again.
- In verifying phase, navigate Library, Playlists, and the exact destination. Use verifyPlaylist when its name, song titles and artists are visible. Scroll if more verification is needed.
- Tap and hold must reference a current text element ID. Never guess element IDs. Home and spotlight are system gestures. ScrollDown scrolls content upward to reveal lower rows.
- Never delete, remove, purchase, subscribe, edit the source, sign in, change account settings, send messages or open unrelated apps. Use needHelp for obstacles. No music playback is necessary.
