How to actually
use Kimi K3
The free, open model that just knocked the paid ones off the top of the AI coding leaderboard. Here's how to put it to work, whether you write code or have never touched a terminal in your life.
What it's for
What Kimi K3 is best at
It's a chat assistant like ChatGPT or Claude, but it's currently the strongest at these four things.
🎨
Building things you can see
Websites, landing pages, app screens, small tools and games. It topped the leaderboard for turning a description into a working interface, so this is its party trick.
📸
Working from a picture
Show it a screenshot of a design, a competitor's page, or a rough sketch, and it reads the image and builds or fixes from what it sees. No describing every detail in words.
📚
Reading huge documents
It holds about a million words at once, so you can paste a whole contract, a year of reports, or a long transcript and ask questions across all of it in one go.
🤖
Doing multi-step jobs
Give it a goal, not just a question, and it can plan the steps and work through them, the kind of long task that used to need a person babysitting it.
✓You can use it free. The Kimi website and app let you chat with K3 with a daily usage limit, no card needed to start.
!Don't paste anything confidential on the free tier. Kimi's own policy says free-tier conversations may be used to improve their models. For client data or private business info, use a paid plan (which turns that off) or keep it generic.
!Heavy or automated use costs money through their paid plans or pay-as-you-go API. For learning it and everyday tasks, the free tier is plenty.
The Setup
Tick off the 5 steps
Tap each step as you go. No coding, promise. The whole thing takes a few minutes.
0/5
1. Open Kimi
Website or phone app, your choice
Go to kimi.com in any browser, or install the Kimi app on your phone. Sign in with Google or an email, it is free. You will land on a chat screen that says "Ask anything, or task an agent".
2. Make sure you are on K3
The newest, strongest model
Near the chat box there is a model name you can tap. Pick K3 (or K3 Max if you see it) so you are using the new one this guide is about, not an older version.
3. Ask it to build something small
This is where it shines
Type what you want in plain words, for example "build me a simple one-page site for my dog-walking business with a booking button". It writes it and shows you a live preview you can look at and tweak.
4. Show it a picture
Its best hidden feature
Tap the attach or image button and upload a screenshot, a photo of a sketch, or a design you like. Then say "make me something like this" or "what is wrong with this layout". It reads the image and works from it.
5. Feed it something long
Where the huge memory pays off
Upload or paste a long document, a contract, a report, a transcript, and ask a real question: "pull out every deadline and who owns it", or "summarise this for a customer in 5 bullet points". It handles very long text in one go.
You're in. Now grab a prompt below and give it a real job 👇
Try these first
3 prompts to start with
Copy one, paste it into Kimi, and swap the [brackets] for your own details.
1 · For a business owner
No tech skills needed
Act as my marketing assistant. My business is [what you do, who you help]. Build me a simple, modern one-page website with a headline, three benefits, and a contact button. Show me a preview, then I will ask for changes.
2 · The screenshot trick
Attach an image first
Here is a screenshot of a page I like the look of. Build me my own version for [my business], keeping that clean style but using my words: [paste a sentence about what you offer].
3 · For a vibe coder
Build and iterate fast
Build a single-page [web app / tool / small game] that does [describe it]. One HTML file, no setup. Show me a working version, then keep a running list of what to improve and ask me which to do next.
💡The trick most people miss: talk to it like a smart new hire, not a search box. Give it context (who it is for, what good looks like), then ask it to show you a first version and iterate. Be specific in, get something great out.
Common questions
Quick answers
No. You describe what you want in normal English and Kimi writes and shows it. Coding knowledge helps for bigger projects, but for a landing page, a summary, or a small tool, plain words are enough.
Yes, the Kimi website and app let you use K3 with a daily limit at no cost. There are paid plans and a pay-as-you-go developer option for heavy or automated use, but you do not need them to learn it or do everyday tasks.
On the free tier, Kimi's own policy says your conversations may be used to improve their models. So do not paste confidential client data, contracts, or anything sensitive there. For private work, use a paid plan (which turns that off) or keep the details generic.
They overlap a lot. Kimi K3's standout strengths right now are building visual things (websites and app screens), working from screenshots, and reading very long documents. If that is your job, it is worth having in your kit alongside the others.
Kimi is releasing the model's inner workings publicly, so advanced teams can run it on their own computers. You do not need to care about this to use it. For almost everyone, the free website or app is the way in.
Normal. Treat the first answer as a draft. Tell it exactly what is off ("the button does not work", "make it warmer", "shorter") and ask it to fix that one thing. Two or three rounds of that usually gets you there.
