These two overlap more than their marketing suggests; the split is usually about how you work.
For Everyday questions and spoken practice; Short-video and Douyin scripts, Doubao is the more direct fit. For Professional developers writing code daily; Team code review, GitHub Copilot gets there with less fighting.
Both have free tiers, so cost only separates them once you hit the limits. Context limits aren't published for both, so treat this as untested until you hit the ceiling yourself.

Everyday questions and spoken practice; Short-video and Douyin scripts; Students and light office tasks. Its strongest point: Free tier already covers daily chat, search and images. Watch out for: Professional document work sits behind the paid tiers.
Professional developers writing code daily; Team code review; Enterprise release pipelines. Its strongest point: Completion and edits happen in the editor, with no window switching. Watch out for: Usage is metered in AI Credits, which is hard to forecast.
There's no reason to pick a single winner if you already pay for one: use the free tier of the other for the tasks it clearly does better.
Doubao if you want Everyday questions and spoken practice. GitHub Copilot if Professional developers writing code daily. Neither has a learning curve worth worrying about past the first day.
Yes — both have free tiers, and the pair covers more ground than either alone.
