Are these AI underdogs actually free?

Yes — all four (DeepSeek, Qwen, Perplexity, Mistral Le Chat) have free web-based chat interfaces. Most don't even require a signup to try. Some have paid tiers for higher usage, but the free tier is generous and the right place to start.

Why use one of the underdogs instead of ChatGPT or Claude?

Three reasons people switch. (1) The underdog is better at a specific thing you do — Perplexity for research with citations, DeepSeek for math/code reasoning, Qwen for multilingual work. (2) You want options that aren't tied to one company's roadmap or pricing. (3) You want a free tier that doesn't bump you to a smaller model at peak hours.

Are the Chinese AI tools (DeepSeek, Qwen) safe to use?

Safe to chat with for general use — yes. Safe to share work secrets, proprietary code, or sensitive personal information with — no, just like you shouldn't with any AI tool unless you're on a paid tier with explicit data-handling guarantees. US employers often have policies against routing work data to Chinese AI services; check before using them at work.

How is Perplexity different from a regular AI chatbot?

Perplexity is search-grounded. When you ask a question, it searches the live web first and then synthesises an answer with citations to the sources it used. ChatGPT and Claude are answering from training data (which has a cutoff date); Perplexity is answering from today's web. Best for current events, research, and anything where you want to verify the sources behind an answer.

Which underdog should I try first?

Depends on what you're trying to do. Doing research or asking 'what's happening with X right now'? Try Perplexity. Working in a non-English language or with non-English content? Try Qwen. Working on math or reasoning-heavy problems? Try DeepSeek. Care about EU-based data residency or want a European alternative to US AI? Try Mistral's Le Chat.

Are these going to replace ChatGPT, Claude, and Gemini for me?

Probably not — most people will keep one of the big 3 as their daily driver and reach for an underdog when it specifically wins. The point of knowing about the underdogs isn't to replace your habits; it's to have the right tool when ChatGPT's answer feels off, when the citation matters, or when the free tier hits its cap and you need somewhere to go.

If the only AI you’ve heard of is ChatGPT, you’ve heard of about a fifth of what’s available — and not always the right fifth for your specific question. The underdogs aren’t lesser tools waiting to catch up; many of them are genuinely competitive with the big 3 and free where the big 3 charge $20/month.

Here are four worth keeping a tab open for.

Why bother knowing about the underdogs

They have specific strengths the big 3 don't match

Perplexity does search-grounded answers with citations — neither ChatGPT nor Claude does this as cleanly. Qwen is dramatically better than the big 3 at certain non-English languages. DeepSeek's reasoning on math and code problems regularly wins blind comparisons. "Best AI" depends on the question.

They're free where the big 3 paywall

If you've hit ChatGPT's free-tier cap and don't want to pay $20/month, opening DeepSeek or Qwen in a new tab is a real answer. Same conversation quality, no subscription, no usage cap that actually bites for casual users.

They give you a backup when your main tool is down

ChatGPT has outages. Claude has outages. Whichever one is your daily driver, knowing one underdog means you're never blocked because of someone else's server problem.

It reduces your dependence on one company

Every AI company is changing pricing, models, and policies constantly. If your work or habits depend entirely on one of them, you're at the mercy of decisions you didn't make. Knowing where to go if your favorite tool gets worse is a quiet form of resilience.

The four worth keeping a tab open for

1. DeepSeek

🇨🇳 Made by: DeepSeek (Chinese AI lab). 💲 Cost: Free. 🌐 Where: chat.deepseek.com — no signup required to try.

DeepSeek burst into the conversation in early 2025 when its R1 reasoning model performed comparably to OpenAI’s top tier at a fraction of the cost. It’s particularly strong at problems that require step-by-step reasoning — math, code, logic puzzles, debugging — and shows its work in a way most chatbots don’t.

🧮Best for: math, code, multi-step reasoning, anything that benefits from "thinking out loud"
⚠️Watch for: it's a Chinese service — don't share work secrets or anything employer-sensitive without checking your company's policy
🆚Wins over big 3 when: the question is reasoning-heavy and you want to see how it got to the answer

Try DeepSeek →

2. Qwen (Alibaba)

🇨🇳 Made by: Alibaba. 💲 Cost: Free. 🌐 Where: chat.qwen.ai — no signup required to try.

Qwen is Alibaba’s flagship AI and is genuinely strong at multilingual work. If you’re translating between English and a language ChatGPT handles indifferently — Mandarin obviously, but also Arabic, Hindi, Indonesian, Vietnamese, Korean — Qwen often produces noticeably better output. It also handles long documents well.

🌏Best for: non-English work, translation, multilingual conversations, long-document analysis
⚠️Watch for: same data-residency considerations as DeepSeek for work use
🆚Wins over big 3 when: your work touches Asian languages or you need the cheapest path to a capable model

Try Qwen →

3. Perplexity

🇺🇸 Made by: Perplexity (US-based). 💲 Cost: Free tier (generous) + $20/mo Pro. 🌐 Where: perplexity.ai — no signup needed for basic use.

Perplexity is a different paradigm from the other three. Instead of answering from training data (which has a cutoff date), it searches the live web first and synthesizes an answer with citations to the actual sources it used. Click any citation, see the source, verify it. For research, current events, or any answer where “where did this come from?” matters, nothing else compares.

🔎Best for: research, current events, fact-checking, "explain X with sources I can verify"
⚠️Watch for: it's a different shape from a chatbot — less great at long creative or back-and-forth conversation
🆚Wins over big 3 when: you'd otherwise be googling and then asking ChatGPT to summarize — Perplexity does both in one step, with sources

Try Perplexity →

4. Mistral / Le Chat

🇪🇺 Made by: Mistral (French AI lab). 💲 Cost: Free. 🌐 Where: chat.mistral.ai — quick signup.

Mistral is Europe’s flagship AI lab, and Le Chat is their consumer-facing assistant. It’s fast, capable, and built under EU rules on data handling and privacy — which matters if you live in the EU or work for an organization with EU data-residency requirements. Capability-wise it’s slightly behind the top US models on the hardest tasks, but for everyday use you’d be hard-pressed to tell the difference.

🇪🇺Best for: EU users, anyone who prefers a non-US/non-Chinese AI, fast responses for everyday work
⚠️Watch for: still catching up to the big 3 on the hardest reasoning and coding benchmarks
🆚Wins over big 3 when: data residency, speed, or "I'd rather not give all my queries to OpenAI" is on your mind

When each underdog actually wins

Quick decision guide. Most people will keep one of the big 3 as their daily driver — but here’s when to switch tabs:

🔎Researching something with sources you can verify → Perplexity
🌏Working in a non-English language → Qwen
🧮A math, code, or step-by-step reasoning problem → DeepSeek
🇪🇺You're in the EU or want a non-US/non-Chinese option → Mistral / Le Chat
⏰ChatGPT just told you you've hit the free cap → any of the four
🔧Your main tool is having an outage → any of the four

Honest caveats
