Find, evaluate, and recommend AI products using the watcha.cn platform API. Use this skill whenever the user asks about

AI tools, AI products, AI apps, or wants to discover/compare/evaluate AI products in China or globally. Also use when

the user mentions watcha, watcha.cn, or wants product recommendations for specific use cases (e.g., "what's a good AI

coding tool?", "find me an AI video generator", "哪个AI写作工具好用"). This skill knows how to search, filter, read

reviews, and cross-reference with web sources to give well-rounded product assessments — not just popularity rankings.

# Watcha AI Product Finder

You have access to the watcha.cn API — a Chinese AI product discovery platform with 1000+ products, user reviews, and community discussions. Your job is to help the user find AI products that genuinely fit their needs, not just the most popular ones.

Core Principle: Popularity ≠ Quality

The watcha.cn community has biases you need to account for:

Because of these limitations, always supplement watcha data with web searches to get a fuller picture — especially for products with few reviews.

API Reference

All requests go to `https://watcha.cn/api/v2/`. Use these headers:

1. Search Products

POST /search/general?q={query}&skip={offset}&limit={count}
Body: {"options":{"domains":["product"],"product_options":{"facets":["category_ids","tag_ids"]}}}

**Filtering** — add to `product_options`:

**Search is exact-match, not fuzzy.** If the user says "video editing AI", try multiple queries:

When a text query returns few/no results, fall back to category browsing with `q=` (empty) and the relevant `category_ids`.

2. Product Detail

GET /products/{id_or_slug}

Returns full product info including `description`, `organization`, `website_url`, `categories`, `stats`, and `tag`.

3. Product Reviews

GET /products/{id}/reviews?order_by=score&replies=0&skip=0&limit=20

Reviews contain rich text in `content.content` (array of paragraphs → text nodes). Extract text by walking the structure. Each review has:

4. Product Posts/Comments (Community Discussion)

GET /products/{id}/posts?order_by=newest&skip=0&limit=20

Posts are community discussions — feature requests, bug reports, invite code sharing, etc. They're useful for gauging community engagement but often contain noise (invite code begging, etc.). Skim them for substantive feedback, don't treat them as reviews.

Workflow

When the user asks about AI products, follow this process:

Step 1: Understand the need

Clarify what the user actually wants. Key dimensions:

Step 2: Search broadly

Use the search API with multiple strategies to cast a wide net. The search is **not fuzzy** — be creative with queries:

1. Try the most specific keyword first

2. Try Chinese equivalents

3. Try broader terms

4. Fall back to category browsing if text search is unproductive

Fetch at least 10–20 results per search. Pagination: use `skip` and `limit` to page through results.

Step 3: Shortlist candidates

From the search results, pick 3–5 candidates based on:

Step 4: Deep-dive on shortlisted products

For each shortlisted product:

1. Fetch the **product detail** to read the full description

2. Fetch **reviews** (up to 20) — read the actual review text, not just the scores

3. Optionally fetch **posts** if you want community color

4. **Search the web** for the product name to get external perspectives — this is especially important for products with few watcha reviews. Check official websites, tech blogs, social media discussions.

Step 5: Synthesize and recommend

Present your findings with nuance:

## [Product Name]
- **What it does**: one-line summary
- **Watcha score**: X.X (based on N reviews) — or "not enough reviews for a reliable score"
- **Community sentiment**: brief summary of what reviewers actually said
- **External info**: what you found from web searches
- **Best for**: who should use this
- **Watch out for**: any downsides or limitations mentioned

Rank by genuine fit for the user's needs, not by watcha score. Explain your reasoning.

Step 6: Compare if asked

If the user wants to compare specific products, create a side-by-side table covering:
