Changelog & Release Notes

v50.13 is a major update for the whole YTubeTranscript ecosystem. It refreshes the AI engine used by the Chrome/Chromium edition and brings the same functional core to Firefox, together with Mozilla-specific permission handling improvements.

• Completely refreshed AI catalog: updated support for Google Gemini, OpenAI and Anthropic models, including the newer Gemini 3.x, GPT-5.6 and Claude 5 generations.
• New FREE AI model: Gemini 3.5 Flash-Lite replaces Gemini 2.5 Flash as the default free cloud model.
• Smarter legacy model compatibility: when a previously saved model is no longer available, YTubeTranscript automatically selects a valid alternative without breaking the workflow. FREE users remain on a free model, while PRO users keep their selected provider whenever possible.
• Chrome / Chromium updated: v50.13 consolidates the new AI catalog, model selection and legacy fallback logic in the primary Chromium baseline.
• Firefox aligned with v50.13: the same AI catalog and model-selection logic have been ported and validated on the Firefox edition.
• Clearer Firefox permissions: optional permissions are requested only when a feature actually needs them, including remote AI, downloads and supported integrations.
• Improved Firefox integrations: permission flows for Notion, Cloud Backup, authentication and in-app support have been updated.
• Ollama preserved: local AI processing remains separate from the permissions required by cloud services.
• Improved reliability: model catalogs, model selection, fallback behavior, integrations and key runtime workflows have undergone compatibility and stability validation.

We fixed an annoying issue: when downloading summaries after watching multiple videos, the file name will now always match the correct video.

• Precise File Names: Fixed the issue where downloaded files kept the name of a previously watched video.
• Seamless Navigation: You can switch between YouTube videos and the extension will instantly update its data without needing a page reload.

We improved transcript clean-up by removing pauses and unnecessary texts automatically generated by YouTube.

• Goodbye Useless Text: Automatically removes accessibility labels (like '1 minute and 6 seconds') that cluttered your summaries.
• Secure Updates: The extension now ensures you are always running the latest code for maximum reliability.
• Perfect Exports: Added an extra layer of checking to guarantee clean and readable TXT files every time.

We removed some experimental features that caused slowdowns, bringing the extension back to its usual speed and reliability.

• Stability Restored: Resolved freezes and loading issues introduced in previous versions.
• Perfect Shorts: Maintained high-quality support for short videos without compromises.
• Secure Connections: Network improvements to bypass YouTube's blocks remain active to always guarantee your summaries.

We revolutionized how the extension retrieves video texts, bypassing YouTube's security blocks.

• Block Bypass: The new connection system overcomes restrictions that sometimes prevented obtaining the transcript.
• Total Integration: Works perfectly with all our export features, including Notion and Obsidian.

Pure magic: if a video has no subtitles, our AI will listen to the audio and write it down for you in real time.

• Audio to Text: If YouTube doesn't provide subtitles, the extension will use Gemini AI to transcribe the video's audio directly.
• Maximum Speed: We only analyze the lightest audio stream to guarantee record-breaking results.
• Complete Exports: AI-generated texts work with all extension features (Chat, AI Studio, Notion, Obsidian).

We strengthened the internal engine to retrieve texts even when YouTube tries to block requests.

• Anti-Block Recovery: A new background system bypasses technical limitations ensuring you always receive your summaries.
• 4-Level System: If the first attempt fails, the extension automatically tries three other strategies to get the text.

The extension now instantly recognizes short videos (Shorts) and extracts their texts without hesitation or errors.

• Limitless Shorts: Fixed an annoying error that prevented downloading texts from certain YouTube Shorts.
• Precise Recognition: The extension always knows which video you are watching, even with multiple Shorts open at the same time.

An update dedicated entirely to improving the experience with YouTube's short videos.

• New Reading Engine: A direct approach to ensure Shorts texts are read correctly on the first try.
• Automatic Plan B: If direct reading fails, an invisible backup mechanism immediately kicks in.

The AI now understands the video at 360 degrees: it reads the entire description and automatically recognizes chapters, giving you even more precise summaries and chat answers.

• Description Extraction: The AI can now read the full video description without you needing to click 'Show more'.
• Smart Chapters: Automatic recognition of video chapters to better organize and navigate the content.
• Improved Summaries: AI-generated summaries now take into account not just what is said, but also the titles, chapters, and the full video description.
• Smarter Chat: You can ask the Chat questions about details in the description, like 'What is the link mentioned in the description?'.
• Full Compatibility: These improvements work with all available AI models (Gemini, OpenAI, Anthropic, and Ollama).
• Faster Performance: We've optimized data loading, making the extension quicker at analyzing the page.
• More Accurate Chapters: We improved the system to prevent random links or times from being confused with actual video chapters.
• Smoother Chat: Fixed a minor issue that could slow down the chat when sending messages in quick succession.

Run AI directly on your computer for free and with total privacy using Ollama. We've also added clearer loading screens.

• New AI Option: Added support for Ollama. You can now select it alongside Gemini, OpenAI, and Anthropic.
• Easy Setup: A new settings section to quickly connect the extension to the Ollama models installed on your computer.
• Real-time Reading: Answers generated with Ollama appear word by word, just like with cloud providers.
• PC Optimized: To avoid overloading your computer, very long videos are processed in optimized chunks when using local AI.
• Local Chat: You can also use the Chat feature with Ollama to converse about videos while keeping your data completely offline.
• Better Loading Screens: New loading animations (spinner) with helpful messages, so you always know what the extension is doing.
