How do I see what Douyin says about a brand with AI?
Connect SocialToAI to your AI client over MCP, then ask in plain words. In this recorded run an AI client answered “What are people on Douyin saying about Luckin Coffee?” with 1 request on Douyin: 7 items read in 11.6 seconds for 60 credits ($0.2). Below are the calls it made, the answer with its sources, and the prompt and API calls to run it yourself. Recorded 2026-10-18.
The question
What are people on Douyin saying about Luckin Coffee?
Douyin shows videos in a feed made for you, and a search mixes recent and old ones. Seeing what the videos about a brand focus on means watching them and keeping count.
What the AI did
It chose the tools itself: 1 request on Douyin. Each row is one tool call as the client showed it, with what it sent, how much came back and what it cost.
| Platform | Tool | Sent | Requests | Returned | Credits |
|---|---|---|---|---|---|
| Douyin | brand_buzz | brand: "瑞幸咖啡" · about: "连锁咖啡品牌" · platforms: ["douyin"] · window: "30d" · scale: "small" | 1 | 7 videos | 60 |
| Total | 1 | 7 items | 60 | ||
The answer
What the client answered, from what it had read. The line under each finding is a post it read, or a figure from those posts.
7 of the 7 posts found are about it: 86% positive, 14% neutral, 0% negative. What they mention most:
- Price43%“0.01喝瑞幸教程”3 videos
- Design29%“高蛋白莓果酸奶饮，一杯约含20g蛋白质，可以满足每日约1/3蛋白需求，代餐抗饿。”2 videos
- Where to get it29%“也是在镇上喝上细糠了”2 videos
The posts it rests on

What it cost
1 request, 60 credits in total: $0.2 at the $10 rate. Every answer of the API states the credits it charged and the balance left, so your AI can tell you what a question cost. A call that fails costs nothing.

|---|---|---|
| $10 = 3,000 credits | 300 | $0.2 |
| $50 = 20,000 credits | 400 | $0.15 |
