Final Tip
The real growth comes when you combine several tools.

Many creators now upload 3-7 videos per week using this exact workflow and grow much faster than people editing everything manually.
Start with one or two tools that solve your biggest problem right now (most people start with thumbnails and titles because they give the fastest results). Then add more tools as your channel grows.
