Both tools search the web and show you where their answers come from. The difference is pace. Perplexity gives you a quick answer with sources. Kimi Deep Research takes longer and hands you a full report. This page helps you pick the right one for the job.
Same question, two styles: a quick answer with sources, or a longer wait for a full report.
Many people use both: Perplexity for fast fact-finding, then Kimi for the full report.
We are a Kimi guide site, so we know Kimi best. We have tried to be fair to both. We are not affiliated with Moonshot AI or Perplexity.
Made by Moonshot AI. Deep Research is one of several tools inside Kimi.
Made by Perplexity, a company in the USA. Search with sources is the whole product.

Kimi details come from Kimi's help centre. Perplexity research details come from Perplexity's help centre. Perplexity prices and free limits come from independent pricing trackers, and Perplexity changes plans often, so check perplexity.ai before you pay.
This is the main trade-off. Faster is better for facts. Slower is often better for understanding a whole topic.
Times as stated by each company's help centre. The bars are a rough picture.
Kimi's help centre says an average task has 23 reasoning steps, finds 206 web pages, keeps only the best few, and cites about 26 sources.
Perplexity says Research mode runs dozens of searches and reads hundreds of sources, changing its plan as it learns more.
Both do real reading. Kimi spends longer and writes more. Longer is not always better, so match the tool to the size of the question.
Every answer has small numbers that link to the pages it used, even on the free plan. It is easy to check a claim right away. This habit of always showing sources is what Perplexity is best known for.
A Deep Research report has citations inside the text. Clicking one opens the source with the original passage highlighted. You can also tell Kimi which kinds of sources to prefer, such as official reports or academic papers.
A long report with a table of contents and citations. A visual web version with layouts and mind maps. Save as PDF or Word, or share a public link.
A short answer or a written report with sources. Export as a PDF or document, or turn it into a Perplexity Page to share.
Kimi can turn findings into slides, a spreadsheet or a website. Perplexity has Labs for building files and small apps.
The entry prices are almost the same. What differs is how research is counted.
Kimi says one report uses about 5 to 10% of a month's credits on Moderato. The "10 to 20 reports" figure is our sum from that, if you use credits for nothing else. Credits are returned if a task fails. Kimi pricing
Perplexity's help centre says "limited" for free and "extended" for Pro without giving numbers. Prices are from independent trackers. Normal quick searches are free.
You want the answer and the source in seconds.
Quick, current answers with links, many times a day.
A long, structured report you can save as Word or PDF and share.
A full overview with a table of contents. Ask it to prefer academic sources.
Perplexity for a quick comparison. Kimi if the decision is big and you want detail.
Run Deep Research, then make slides from it in the same app.
Short answers and follow-up questions help you learn as you go.
Use Perplexity to explore and find the right question. Then give Kimi that question for the full report.
Tick every line that sounds like you. The result updates as you go.
This is a simple guide based on the table above, not a test. Nothing you tick is saved or sent anywhere.
Give both tools the same research question and compare. These prompts are narrow enough to judge fairly.
What are the main trends in the electric bicycle market in Europe from 2023 to now? Use official reports and industry data where possible, and give sources.
Summarize what research says about the effect of sleep on memory in teenagers. Prefer academic papers from the last 10 years and give sources.
Compare heat pumps and gas boilers for a small home in the UK: cost to install, cost to run, and grants available in 2026. Give sources.
Then judge each result:
Add a time range, a country or region, and what you want to learn.
Say "prefer official reports and academic papers" if that matters.
Two focused questions beat one vague one.
On Kimi, do not press stop. Refresh the page if it looks stuck.
Check any number, date or quote before you use it.
Do not paste confidential information into either tool.
