The platform tools are competent at what they were built for. The problem is what they were built for.
1. Each one sees a single platform
Xingtu (巨量星图) sees only Douyin. Pugongying (蒲公英) sees only Xiaohongshu. Your campaign runs across both, and tomorrow it runs on TikTok and Instagram too. No native tool will ever show you the whole picture, because no platform has an incentive to build one.
2. They grade their own homework
Xingtu is ByteDance reporting on ByteDance inventory. Pugongying is Xiaohongshu reporting on Xiaohongshu creators. These tools exist to keep your budget on their platform. The numbers are real. The framing is never neutral. The same logic applies one level up: your agency reports on the campaign your agency ran. Everyone in the chain grades their own homework, except the brand writing the checks.
3. Charts are not answers
Native dashboards tell you what happened. They do not tell you whether it was good, why it happened, or what to do next. That work still lands on your team: screenshots, spreadsheets, and a deck due Friday.
