Description

Removes AI summaries completely. The AI_SUMMARIES flag was never turned on in production, so production users keep exactly what they see today. Plus, product team decided to mold summaries into Episode chat so the feature become unnecessary.

Generated chapters keep working, now without summaries

• TranscriptManager.loadSummaryText() was the only code that fetched <transcript>-meta.json, which is also how generated chapters get saved.
• It's replaced by loadGeneratedChapters(), which only depends on GENERATED_CHAPTERS.
• The player's ChaptersViewModel calls it for its episode. That covers both the player and Episode details, since both screens share that view model with their Chapters tab.
• In the player it runs once per playing episode, and not when nothing is playing. Before, it re-fetched meta.json on every player update.

Player

• The Summary tab is gone, along with SummaryFragment, SummaryViewModel and the summary analytics event.

Episode details

• The redesign from Redesign episode details screen with AI summaries #5353 only showed with the flag on, so it's removed. That covers the content tabs on the page, the sticky tab bar, the inline chapters/transcript/bookmarks, the summary paywall and the date/duration line.
• The screen is now the production layout: the transcript card, the show notes, and Details / Chapters / Bookmarks as swipeable tabs.
• The "Chat with Episode" banner under the transcript card stays (when EPISODE_CHAT is on), as in production today. [Episode Chat] Remove the chat entry from Episode details #6146 removes it separately.
• Both fragment_episode.xml layouts are back to their pre-Redesign episode details screen with AI summaries #5353 version. The only difference is that the show notes start visible, as they do in production.

Also removed

• Feature.AI_SUMMARIES and OnboardingUpgradeSource.AI_SUMMARIES.
• SummaryPaywall, SummaryContent and MarkdownUtils.
• The showCloseButton option that Redesign episode details screen with AI summaries #5353 added to the transcript toolbar.
• Six strings (episode_summary, summary_upsell_title, summary_upsell_description, summary, player_tab_summary, and the already unused description), from values/ and all 16 translations.
• No database migration is needed.

Visible change in debug and prototype builds

• These builds had the flag on by default, so they now show the production Episode details layout instead of the redesign.

Testing Instructions

Use a debug build with "Generated chapters" on in Beta features.

1. Open Episode details for an episode with a transcript and generated chapters (Radiolab › Patient Zero). ✅ Details / Chapters / Bookmarks tabs at the top, a "View transcript" card, then the show notes.
2. Tap Chapters. ✅ The generated chapters show ("These chapters are automatically generated…"). Logcat shows the …-meta.json request.
3. Open Episode details for an episode without a transcript. ✅ The show notes keep their 16dp gap below the date/duration row, as before.
4. Rotate to landscape. ✅ Same layout, nothing missing or overlapping.
5. Open the full-screen player. ✅ Tabs are Playing / Details (if there are show notes) / Chapters (if there are any) / Bookmarks. There's no Summary tab.
6. Beta features no longer lists "AI Summaries".

This looks good to merge and I found nothing blocking. Generated chapters still get fetched on both screens. ChaptersViewModel is created and collected straight away in EpisodeContainerFragment and PlayerContainerFragment, and ChaptersFragment uses the same view model from its parent, so meta.json is fetched once per episode. loadLocalTranscripts waits up to 1 minute for the show notes to finish processing, so dropping the old re-fetch on every player update doesn't stop chapters loading for a newly started episode. I found no remaining references to the removed view IDs, strings, AI_SUMMARIES or the EpisodeSummary* events.

This looks good to merge and I found nothing blocking. Episode details is back to the production layout, the player has no Summary tab, and generated chapters are still fetched once per episode from ChaptersViewModel on both screens. The one difference from main is that the player no longer retries a failed meta.json fetch.

Non-blocking

• modules/features/player/src/main/java/au/com/shiftyjelly/pocketcasts/player/view/chapters/ChaptersViewModel.kt:71: if the meta.json request fails once (for example, playback starts offline), generated chapters stay missing in the player until a different episode plays. On main it only recovered because every player update fetched again. Add a retry if that matters, or accept it. [AI Summaries] Remove AI summaries #6147 (comment)

[claude]

(non-blocking) If the -meta.json request fails once, for example when playback starts offline, the player won't show generated chapters for that episode until a different episode plays. On main this only kept working by accident: SummaryViewModel stayed NotAvailable when summaries were off, so every listDataLive emission fetched again. Now loadGeneratedChapters runs once per episodeUuid and swallows the error. If that matters, retry on failure, e.g. have it return a success flag and retry with backoff, or re-trigger it on a connectivity change. Otherwise it's fine to accept and leave as is.

I found nothing new since the last review, and the one open finding is resolved. 8bf5e04 makes loadGeneratedChapters return whether it succeeded. ChaptersViewModel now retries a failed meta.json fetch with backoff (5s, 10s, 20s, 40s, 80s). collectLatest cancels the retry when the episode changes. This fixes the offline-start case from #6147 (comment).

Version 8.23 has now entered code-freeze, so the milestone of this PR has been updated to 8.24.

Nothing new since the last review, and nothing is still open. This push rebases the same 8 commits onto the latest main (fc3bb35). The diff is the same size (44 files, +219/−2520), and the code coming in from main doesn't use anything this PR removes.
