This update focuses on refining the experience and improving stability for AI Book Breakdown and AI OCR. We’ve added a (coarse-grained) screenshot mode for book breakdown with a smoother output workflow, enhanced the Smart Dictionary breakdown and card templates, and made math-heavy and high-frequency card-creation workflows more fluid and controllable. Highlights • AI Book Breakdown (Enhanced Screenshot Mode): Optimized for math/science content with a more coarse-grained screenshot breakdown, making complex formulas and charts easier to turn into structured notes. • Smart Dictionary Breakdown: Introduces automatic title-link creation, supports general concept extraction, adds a dedicated English vocabulary mode, and includes a new Practice Mode for organizing questions into study cards. • AI OCR Card Templates Upgrade: Introduces template-based configuration (the old prompt-only editing mode is deprecated, but existing prompts remain usable). Supports per-field settings (Rich Text/Markdown, cloze, etc.), plus font and color controls. Detailed Updates 1) AI Book Breakdown: More Stable, Clearer Output Workflow • Upgraded to a two-stage workflow: Take notes first → Organize & generate output, breaking the 100-page limit (processing very large batches may require more time and resources). • Reduced overhead in screenshot mode to lower the cost of large-scale screenshot breakdown. • Improved output visibility: makes the “note collection” process more transparent and easier to learn from. • Default output is now Outline/Framework Mode. • Enhanced question-driven prompts to better support theme-based reading and structured understanding. 2) Smart Dictionary Breakdown: Auto Indexing & Auto Linking • New Smart Dictionary breakdown with automatic title-link creation for quick indexing and traceability. • Three modes available: • General Mode: Structured extraction of concepts, theorems, names, places, and more. • English Learning Mode: Specialized extraction for vocabulary and language learning. • Practice Mode: Extracts exercises from documents and organizes them into cards by question number for efficient practice and review. 3) AI OCR: Stronger Card Template System • New Card Template Configuration: • Per-field configuration. • Supports Rich Text or Markdown. • Supports Cloze (fill-in-the-blank) settings. • Rich text fields support custom fonts and colors. • Markdown cloze supports tap-to-reveal answers. • UI improvements for AI OCR. 4) Stability & Fixes • Fixed two crash issues. • Fixed YouTube playback issues. • Fixed an issue where deleting a # tag could invalidate all tags. • Fixed an issue where continuous rectangle excerpts could not use AI OCR.
