What is Kimi?

Kimi is an AI assistant created by Moonshot AI, a Chinese AI company founded in 2023. It's famous for one thing above all else: massive context windows.

While most AI assistants struggle with documents longer than 50 pages, Kimi can handle:

  • 200K tokens (approximately 150,000 words or 300+ pages)
  • Some versions support up to 2 million tokens
  • Multiple large documents simultaneously

Think of Kimi as the AI that actually remembers your entire book, contract, or research paper.

✅ Prerequisites Checklist

Before starting, ensure you have:

  • [ ] Web browser (Chrome, Firefox, Safari, or Edge)
  • [ ] Internet connection
  • [ ] Documents to analyze (PDFs, Word docs, or text files)
  • [ ] Optional: Mobile device for Kimi app
  • [ ] Optional: Chinese language knowledge (helpful but not required)

Moonshot AI Background

Company Overview

  • Founded: 2023 by Yang Zhilin (ex-Google Brain)
  • Headquarters: Beijing, China
  • Focus: Long-context language models
  • Funding: $1B+ valuation (2024)

Why Long Context Matters

Most AI assistants have a "memory limit" — they can only consider a certain amount of text at once:

| AI Assistant | Context Window | Approximate Pages | |--------------|----------------|-------------------| | ChatGPT (Free) | 8K tokens | ~6 pages | | ChatGPT (Plus) | 128K tokens | ~100 pages | | Claude (Free) | 200K tokens | ~150 pages | | Claude (Pro) | 200K tokens | ~150 pages | | Kimi | 200K-2M tokens | ~150-1500 pages |

What This Means in Practice

With ChatGPT: Upload a 50-page report → AI forgets the first half by the time it reads the end

With Kimi: Upload a 300-page book → AI remembers everything, can cross-reference chapter 1 and chapter 20
