Can I limit search results to my watch history or subscribed channels?

Filmot cannot limit search results or matches to your YouTube watch history.

For your subscribed channels, you can build the list yourself and search only inside it:

• In the channel lookup box on the home page, subtitle search or metadata search, type a channel name and click a suggestion. You can also paste a comma-delimited list of handles or UC channel IDs, for example @LinusTechTips,@JerryRigEverything,@Dave2D,@GamersNexus. Handles and channel IDs can be mixed in one list.
• Use up to 200 selected channels per search.
• If an Include/Exclude switch is shown, choose Include to search only inside the selected channels.

To reuse the list, bookmark the search page. Signed-in users can also save a search with its selected channels; see Saved Searches.
