YouTube link actions
When you paste a YouTube link into the input, Lumo can offer actions such as summarize, key points, script, research material, subtitles, and translation.
Transcript pipeline
The sidecar checks cache first, then attempts official captions. If no official captions are available and ASR is configured, it falls back to speech recognition.
cache -> official captions -> ASR fallbackASR configuration
Remote ASR uses the Groq key configured in YouTube settings. Voice input can also run in local Whisper ONNX mode or remote mode depending on your settings.
How creators use it
Use YouTube and subtitles as source material for topic research, script drafting, subtitle proofreading, and Shorts splitting. Keep source links and transcript artifacts with the content project.
Use transcripts as source material
Transcripts are useful for extracting arguments, examples, structure, vocabulary, and timing. They are not a replacement for your own script. Ask Lumo to summarize, compare, or repurpose the material into your own angle rather than copying another creator's wording.
Check transcript quality
Before using subtitles for writing, scan speaker names, timestamps, proper nouns, numbers, and mixed-language sections. Official captions can still contain errors, and ASR fallback can mishear names or technical terms.
Use transcripts as references. Verify important claims before publishing.
Turn subtitles into concrete outputs
Useful follow-up tasks include: produce a structured brief, find 5 short-clip candidates, proofread SRT timing and wording, write a platform-specific summary, extract title ideas, or compare several videos before planning your own piece.
Keep media keys scoped
If your build uses remote transcription or image services, keep those keys in Settings and avoid pasting them into chat. When a key stops working, check Settings first, then retry the transcript or voice action.
