Cutting away to something - a street, a desk, hands doing the thing being described - is the oldest trick in editing and the one that keeps people watching. Doing it by hand means finding the footage, trimming it, and placing it on the right word. SnapDub does the finding and leaves the deciding to you.
All of it inside the clip editor, on the clip you are looking at.
Not the title, not tags - the words in that clip. "The thing about compounding is that nobody feels it for the first ten years" has no searchable noun in it, which is why keyword matching returns nothing usable here. What is needed is the picture behind the sentence, and that is what gets looked up.
Stock is uneven. One suggestion means taking what you are given; three means one of them is usually right, and if none is, you close the tab and nothing has happened to your clip.
Pick one and it drops onto the clip muted - stock comes with its own soundtrack and nobody wants that under a voice. From there it is an ordinary overlay: drag it, resize it, change when it starts and ends, or take it off.
Most tools that do this place the footage themselves, as part of one automatic pass. It is the obvious design and it is a reasonable bet: more clips finished, less clicking.
We took the other side of that bet. A clip you are about to post cannot afford one wrong cutaway, and a cutaway that lands on the wrong word is the thing a viewer notices first. So the work of looking is done for you and the judgement stays yours.
It is also per clip rather than per batch, for the same reason. An hour of talk can produce thirty clips here; some of them want cutaways and most do not, and being handed thirty sets of suggestions to dismiss is not help.
Every clip you are shown is licensed for commercial use. Post it, run ads on it, put it on a client's channel - there is nothing to clear and no attribution demanded of you.
What you pick is copied into your own workspace, not linked to from somewhere else. A clip you made in March still renders in December, whatever has happened to the original since.
Every paid plan, from €9 a month up. No separate charge, no per-clip cost, and no allowance that runs out part-way through a batch.
