Things to know
Usage Tips
- Take the time to refine your channel feed first; the quality of viral content found by the tool depends on whether the channels you follow are truly in the same niche.
- After getting the analysis, focus on the hooks and structure; do not copy the expressions verbatim, as this is ineffective and poses copyright risks.
- After generating the script, read it yourself to make it conversational; sentences written by AI often sound too formal when spoken aloud.
- Organize your video ideas by series using projects, which is more efficient than searching for them from scratch every time.
- The official package is subject to adjustment; confirm the quota and export rules before long-term reliance.
