How to evaluate results06 / YOUR DATA
Pause finding stays local.
Cloud AI is your choice.
Core placement works without a cloud AI key. Audio is not uploaded to a Monvilo server.
Audio stays on your computer
Monvilo analyzes speech and finds pauses locally. Saving slots and getting feedback happens in YouTube Studio.
Revenue, placement history and channel IDs are stored in your browser. This is not an offline workflow.
You choose whether to connect AI
Connect cloud AI separately for semantic checks and financial analysis. Core placement works without it.
What is sent to the provider?
Semantic checks use the video title, timestamps, slot characteristics and subtitle snippets. Financial analysis uses aggregated metrics and your question. Requests may incur separate provider charges.
07 / QUESTIONS

Compatibility, ad slots and saved results, explained briefly.
Still have a question? Contact usBefore installing
Which videos are supported?
Videos of at least eight minutes on a channel with monetization and an available ad break editor. The extension targets desktop Chrome and Chromium, not Shorts or mobile browsers.
Does it work with voiceover and music?
Yes. Monvilo finds speech pauses even while music continues. You do not need separate voice and music tracks.
Do I need an AI key?
No. Core placement and YouTube feedback work without a key. Cloud AI for semantic checks is optional, using your own key and your provider’s request pricing.
Is Monvilo available in English?
Yes. Monvilo supports English and Russian, follows your browser language by default, and lets you change the language in General settings.
Slots and results
What happens to my existing slots?
Before placing again, choose whether to keep unflagged slots within the selected frequency or replace the manual layout. Surplus manual slots may also be removed. YouTube automatic slots remain in the standard workflow.
How does the archive queue work?
Select videos in the revenue dashboard and Monvilo processes them sequentially. In optimization mode, existing unflagged slots remain in place while Monvilo looks for suitable additions. Keep the working Studio tab active. The workspace shows the reason for a stop and available continuation actions.
Can I restore the original layout?
Yes. The selected queue’s original manual slots are recorded in history and can be restored in Studio. The work history remains. This does not guarantee recovery from every possible failure.
Will ads definitely play?
No. Monvilo places ad slots and checks YouTube feedback. An unflagged slot does not guarantee ad playback, revenue growth, or unchanged retention.
