FAQ
Everything you need to know.
How do credits work?+
1 credit covers up to 20 minutes of video. Most videos use 1 credit. Longer videos automatically use more credits.
What is Deep Analysis?+
A business-grade analysis that goes beyond summary: what the video is really about, the product/service, how it was built and marketed, and the results mentioned.
What is Project Knowledge (Second Brain)?+
It’s a project-level chat that can answer questions across all videos you’ve processed in that project. Instead of asking one video at a time, you ask the workspace and it responds using only your saved sources.
Do multilingual answers really work?+
Yes. Ask in any language and receive the answer in your selected output language, regardless of the video language.
Is there a max video length?+
Yes, it depends on the plan. Starter: 30 min, Pro: 60 min, Growth: 2 hours, Agency: no limit.
