Changelog

September 2026

Credit-based release · the shortest path from PPT to B站/YouTube

• •Mac, iPhone and iPad are all on the App Store now (worldwide) — one universal app sharing one credit wallet; macOS 15.1+ for Mac, iOS 17+ / iPadOS 17+ for iPhone and iPad
• •Credit system: an anonymous Apple account opens a credit wallet, 600 welcome credits on sign-up, AI generation is quoted and frozen before every run
• •Capability walls removed: export resolution (480p–4K), length, covers and titles are unlimited; the only gate is a brand watermark on exports, permanently removed by any first purchase
• •Own AI gateway (dual-channel failover): no API keys on the client; narration, voiceover and covers metered by actual usage
• •Import PPTX / PPSX / PDF / images (PNG, JPG, HEIC, WEBP), with approximated PPTX layout
• •Intent input: one line on how you want it told, and to whom
• •6 platform targets: B站, YouTube, YouTube Shorts, 微信视频号, 抖音, podcast
• •AI narration streamed page by page, in 4 modes: solo / two-person interview / teacher-student Q&A / news anchor, with local rewrites
• •42 Chinese + 16 English voices (Seed-TTS 2.0), 0.5x–2.0x speed, free voice preview
• •Three-pane studio + script editor + ⌘K command palette + AI rewrite diff view; portrait StudioMobile on iOS
• •6 scene animations, AI-extracted, snapped with on-device OCR, editable on a canvas
• •Burned-in subtitles + sidecar .srt, Ken Burns motion and cross-fades, segmented export for long videos, optional H.264 compression
• •Publish Center: AI cover + title candidates + description + chapter timestamps + tags, one-click bundle export

October 2026

Live Activities · new subtitle styles

• •Render Live Activity on iPhone / iPad: watch render progress on the Lock Screen and Dynamic Island, with one tap to continue when paused
• •iOS renders pause automatically in the background or on lock and resume where they left off — long videos are internally chunked into ~3-minute slices so a pause never loses progress
• •5 subtitle style presets: amber on dark, black on white, white on black, white with outline and yellow with outline — short-video big-caption looks out of the box
• •Better narration scripts: improved structure and wording for a more natural, listenable read
• •Platform localization in the English UI: 抖音 now appears as TikTok, and the default publish target and ordering follow your system language
• •Fairer billing: a cancelled render no longer re-charges narration; voiceover and selection caches mean re-rendering unchanged text is never charged twice
• •Assorted performance and stability improvements across rendering, the timeline and voice matching

October 2026

Arabic interface · everyday polish

• •Arabic localization: use SlideTalk with a full right-to-left Arabic interface
• •Experience improvements: everyday interactions refined for a smoother creation workflow
• •Bug fixes: known issues resolved and app stability improved

October 2026

iPhone Duo support · 12 new languages

• •iPhone Duo support: SlideTalk now runs on Apple's new foldable iPhone Duo, with the interface and previews checked in both folded and unfolded states — nothing jumps when you switch
• •Sharper PPT analysis: the AI reads slide structure, text, images, charts and visual elements more accurately, so scripts follow what is really on each page
• •More natural, more localized narration: writing and polishing were reworked for every language, for phrasing, rhythm and cultural nuance that sound native
• •12 new languages: Spanish, Russian, French, Japanese, Korean, Hindi, Italian, Portuguese, German, Dutch, Norwegian and Swedish; the App Store listing now also ships Traditional Chinese
• •Smarter visual effects: highlights, underlines, arrows, zooms and camera moves are matched more precisely and stay in step with the narration
• •Workflow and performance: the PPT-to-video path was reworked for easier editing and smoother rendering
