# Comment analysis: social media comment analysis

Comment analysis is a ready-made SocialToAI tool that returns what the comments under your posts are about: the topics and their shares, the questions asked, who wants to buy and what is complained about, with the comments quoted. A run costs from 38 credits and is priced before it starts; a run that fetches nothing is not charged. Run it here, in your AI over MCP, or over the API.

## What it takes

| Name | Type | Required | What it is |
| --- | --- | --- | --- |
| `targets` | string[] | Yes | 1 to 20 links to posts; they may be of different platforms. |
| `focus` | string | No | What you want to know, in a sentence: adds the comments that speak to it. |
| `topics` | string[] | No | Your own topics, up to 10: the step that finds topics is then left out. |
| `scale` | string | No | The most comments read in all, shared by the posts: small 200, medium 1,000, large 3,000; fewer on a platform whose comments cost more, as the answer says. `"small"` `"medium"` `"large"` (default `"small"`) |
| `max_cost_credits` | integer | No | Refused, free, with the quote, if the run would cost more. |
| `confirm` | boolean | No | true: run it whatever it costs. false: answer the plan and its price, and run nothing. Left out: a costly run, and one that runs in the background, answers its price first. |

## What comes back

| Part | What it holds |
| --- | --- |
| Topics | What the comments are about and the share of each topic, with comments quoted. |
| Questions | The questions people keep asking. |
| Buying intent | Comments from people who say they want to buy. |
| Complaints | What people complain about, with comments quoted. |

Main number: Comments read. Every result states how much of the plan was read and which parts of the price were charged.

## Depths and credits

| Depth | What it reads | From (credits) | How it runs | On the 100 free credits |
| --- | --- | --- | --- | --- |
| Small | Up to 200 comments in all, shared evenly by your posts. | 38 | runs while you wait | On 11 of 14 platforms |
| Medium | Up to 1,000 comments in all, shared evenly by your posts. 500 on Xiaohongshu. | 172 | partly in the background | After your first purchase |
| Large | Up to 3,000 comments in all, shared evenly by your posts. | 492 | runs in the background | After your first purchase |

## Credits by platform

The table is for one post. For several links the total is stated before the run.

| Platform | Small | Medium | Large |
| --- | --- | --- | --- |
| TikTok | 38 | 172 | 492 |
| Instagram | 58 | 266 | 772 |
| X | 42 | 190 | 544 |
| Reddit | 80 | 382 | 1122 |
| YouTube | 50 | 232 | 672 |
| Facebook | 70 | 332 | 972 |
| Xiaohongshu | 270 | 672 | — |
| Douyin | 50 | 232 | 672 |
| Weibo | 50 | 232 | 672 |
| WeChat Articles | 150 | 732 | — |
| Bilibili | 50 | 232 | 672 |
| Zhihu | 70 | 332 | 972 |
| Kuaishou | 40 | 182 | 522 |
| WeChat Channels | 138 | 636 | — |

## How credits are counted

- **You see the price first**: The total is stated before anything starts. It does not grow if there is more to read.
- **Nothing fetched, nothing charged**: If nothing could be fetched, the run is not charged. If it stops partway, you are charged only for the part that finished.
- **Each depth is one price**: A depth has a fixed price on each platform. It is not reduced when there turns out to be less to read, so start small and go deeper when you need more.

## FAQ

**What does a run cost?**

From 38 credits at the Small depth, for one post. The price depends on the depth and the platform, and the table on this page has every number. You see the total before anything runs, and a run never costs more than that.

**What am I charged if a run finds nothing or stops partway?**

If nothing could be fetched, the run is not charged. If content was fetched but the conditions you set filtered all of it out, only the first half of the fetching price is charged. If a run stops partway, you are charged only for the part that finished.

**What happens when a platform fails?**

The run goes on with what could be read, and the result says how much of the plan that was. The price has three parts: two for fetching and one for the AI analysis. When less than half of the planned reading came back, the second fetching part is not charged. The analysis part is charged only when at least nine in ten of the delivered rows were analysed. A call whose outcome is unknown is never retried on our own.

**Which platforms does it cover?**

14 platforms now: TikTok, Instagram, X, Reddit, YouTube, Facebook, Xiaohongshu, Douyin, Weibo, WeChat Articles, Bilibili, Zhihu, Kuaishou, WeChat Channels. The links you give may be of different platforms.

**Can I run it on the free credits?**

Sign-up includes 100 credits, no card. They can run: Small on 11 of 14 platforms. A depth that runs in the background needs purchased credits. Running a tool on a schedule is available after your first purchase.
