Short answer, then the detail.
For Everyday questions and spoken practice; Short-video and Douyin scripts, Doubao is the more direct fit. For Research where sources must be checkable; Fact-checking a claim quickly, Perplexity 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.
Research where sources must be checkable; Fact-checking a claim quickly; Students who need citations. Its strongest point: Every answer carries clickable source links you can audit. Watch out for: Free tier caps you at 3 Pro Searches a day.
Running both is not wasteful here: one earns its keep on retrieval and tool use, the other on long text you intend to keep.
Doubao if you want Everyday questions and spoken practice. Perplexity if Research where sources must be checkable. 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.
