Kimi Review: Where Its Long-text Strength Really Shines

Kimi's core selling point is "long text." How does it actually perform in practice? This article is based on three consecutive weeks of testing.

Long-text Reading: ★★★★★
Upload a 100-page PDF research report directly and ask it to summarize core conclusions, extract key data, and organize by chapter — everything hits accurately, with page citations. Upload an entire novel and ask about plot details — it answers fluently. This is Kimi's core moat.

Web Search: ★★★★☆
Kimi's web search quality is good, providing sourced information. Timely news gets fast responses, but complex multi-step queries (like "compare funding of three companies") occasionally miss things.

File Processing: ★★★★☆
Supports PDF, Word, Excel, images. Table extraction accuracy is high, but complex layouts (multi-column, scanned) need to be converted to clear versions first.

Writing Ability: ★★★★☆
Chinese writing is natural and fluent. Long-form structure is complete. Clearly stronger at "summarizing and distilling" than "creative brainstorming."

Limitations & Notes:
1. First-time processing of very long documents has longer wait times
2. Coding ability is moderate — pair with dedicated programming tools for complex projects
3. Free version has message limits; heavy users need a subscription

Best for: researchers (reading papers), analysts (reading reports), students (reading textbooks), content creators (material organization).

Verdict: If you have heavy long-document reading needs, Kimi is currently one of the best value choices.
