You want to get into artificial intelligence without paying for a subscription, and you keep running into the same three names: ChatGPT, Claude and Gemini. All three offer a free plan, all three handle French properly, and all three are more than enough to learn with. So the real question isn't which one is „the best" in the abstract, but which one matches what you actually want to do this week. A student revising for exams, a tradesperson writing up quotes and an assistant sorting through emails won't make the same choice.

You'll find three things here: an honest comparison of the three free plans (strengths, limits, quotas), a practical method for testing them without burning a whole evening, and a clear signal for when free stops being enough. Good news along the way: nothing forces you to choose. Using all three side by side is actually the smartest strategy when you're starting out, since each quota refills on its own schedule.

Method 1: learn how to use them before picking a side

The tool you choose matters far less than your ability to give it clear instructions — that's the skill to work on first.

Most beginners try ChatGPT for ten minutes, find the answer „average" and conclude that AI is overrated. In 90% of cases, the problem isn't the model but the request: too vague, no context, no example, no expected format. The same well-built prompt gives a decent result on all three tools. A sloppy prompt gives a disappointing result on all three too.

That's exactly the angle Skilzy takes — a French e-learning platform where you learn AI and put it to use right away. More than 15 programs cover image creation, video (UGC content, ads, faceless channels, avatars, voiceovers), music, automation with n8n, prompt writing and AI-assisted coding. The built-in AI Lab gives you access to the real tools with credits included, which saves you from stacking up three or four €20 subscriptions.

Two state-recognised certifications qualify for funding: RS7439 (content marketing with AI) and RS6792 (AI and sales).

If you want to see which track fits your job, take a look at the list of Skilzy programs for learning to use AI: the topics are organised by use case, not by technology. That said, you can perfectly well start with the free plans detailed below. The two approaches complement each other: free tools to get your hands dirty, structured training the day you want professional results and a certification to put on your CV.

Method 2: ChatGPT free, the simplest place to start

Free ChatGPT is still the most versatile option: it writes, summarises, translates, searches the web, reads your files and generates a few images, all in the same window.

It's the tool I recommend first to anyone who has never tried anything, for one simple reason: it's the best documented. Whatever you get stuck on has already been explained in ten tutorials. If you want a full step-by-step, our guide on how to use ChatGPT as a beginner covers signing up and your first prompts.

What you get without paying:

  • Access to OpenAI's recent model with limited usage, then an automatic switch to a lighter model once the quota is used up. You're never cut off, just slowed down.
  • Web search, so answers that take current events into account and cite their sources.
  • File uploads (PDF, image, spreadsheet) to summarise or analyse a document.
  • Voice mode, very handy on mobile for practising a language or dictating ideas while you walk.
  • A memory that keeps your preferences from one conversation to the next.

Its limits, honestly: image generation is stingily rationed on the free plan, quotas vary with server load (they're tighter at the end of the day) and answers tend to be consensual, with a lot of bullet points. For the exact limits at any given moment, the most reliable source is still the official ChatGPT pricing page, because those caps shift several times a year.

Who it's for: general use, office work, revision, translation, first images, looking up recent information.

Method 3: Claude free, the best one for text

Free Claude is the most comfortable of the three with long, nuanced, well-structured text, as well as document analysis.

Built by Anthropic, Claude writes in a more natural, less textbook-ish style than its rivals. In practice: fewer bold headings everywhere, fewer „it is essential to" constructions, paragraphs that actually hold together. If your main need is writing (tricky emails, meeting notes, a website page, a cover letter, an internal memo), it's often the one that needs the least reworking.

Its strengths on the free plan:

  • Long-document analysis: you drop in a 40-page PDF and ask questions about it.
  • „Artifacts", a separate window where Claude produces a document, a table or a mini-tool that you can tweak as the conversation goes on.
  • A tendency to say when it doesn't know, rather than inventing something confidently.
  • Strong performance on code, including for someone who has never programmed.

Its limits: no image generation, and a message quota calculated in blocks of a few hours. If you run a long analysis session back to back, you can find yourself locked out until the reset. Bigger documents also eat through the quota faster. The tier details are on the plans published by Anthropic.

Who it's for: professional writing, document summaries, analysis, reasoning, first steps in code. For more advanced use, our article on building a company chatbot with Claude shows how far the tool can go.

Method 4: Gemini free, unbeatable inside the Google ecosystem

Free Gemini is the obvious choice if you already use Gmail, Google Docs, Drive or an Android phone: the account already exists and the AI sits right next to your files.

There's nothing to create — your Google account is enough. On Android, Gemini can replace the voice assistant and respond from any screen. On desktop, it turns up inside Gmail and Docs to draft or summarise without leaving the page, depending on your country and account type.

Its advantages on the free plan:

  • Image generation, noticeably more generous than its competitors offer for free.
  • A very large context window, useful for handing over several documents at once.
  • YouTube video summaries and image reading (a photo of an exam question, a label, a floor plan).
  • Direct integration with Google Search for recent factual information.

Its limits: quality varies more from one request to the next, because you aren't always served by the most powerful model on the free plan. Work or school accounts sometimes have the integrations switched off by their administrator, and some features land later in France than in the United States.

Who it's for: Android users, anything involving Gmail and Docs, images, factual questions, everyday mobile use.

The comparison in one table

If you only remember one line: ChatGPT for versatility, Claude for writing, Gemini for the Google ecosystem and images.

Criterion ChatGPT free Claude free Gemini free
Getting started The simplest, heavily documented Simple, clean interface Instant with a Google account
Writing quality Decent, slightly textbook style The most natural of the three Decent, variable
Image generation Yes, very limited No Yes, the most generous
Document analysis Yes Excellent on long files Yes, large volumes accepted
Web search Yes Yes Yes, backed by Google
Main limitation Quotas vary with server load Messages capped per time block Most powerful model reserved for paid plans

One detail that will save you some nasty surprises: these quotas change often, sometimes from one month to the next. Never trust a dated comparison, this one included, for a precise figure. Check the providers' official pages before paying for anything.

How to choose in 15 minutes: the three-prompt test

Open the three tools in three tabs, send exactly the same prompt to all three, and keep the one whose answer needs the fewest corrections.

It's the only reliable method, because „best" depends on how you write and what you do for a living. Here are three prompts to copy as they are, replacing whatever is in brackets.

Prompt 1, real writing: „You are [your job]. Write a follow-up email to a client who hasn't replied in three weeks. Polite but firm tone, 120 words maximum, no stock phrases. Context: [two sentences about the situation]."

Prompt 2, comprehension: upload a document you know well (meeting notes, a contract, an invoice) and ask: „Summarise this document in 5 points, then list the 3 most important pieces of information and the 2 grey areas."

Prompt 3, reasoning: „I'm torn between [option A] and [option B] for [your goal]. Ask me 4 questions before answering, then recommend one option and justify it."

That third prompt is the most revealing: a good assistant questions you before making the call. The one that answers straight away without asking anything will serve you generalities.

Count how many corrections each answer needs. The tool that needs the fewest on your own topics is your main tool. The other two become your backups when you hit a quota, which happens sooner than you'd think.

When is free no longer enough? Three signals: you're bumping into the quota several times a week, you need to generate images or videos in volume, or you want to automate repetitive tasks instead of copy-pasting by hand. Before you reach for your card, go through the resources for learning AI for free and ask yourself about the learning path rather than the tool: our guide to learning AI in 2026 as a beginner explains what order to pick up the skills in.

Key takeaways

All three free plans are good. Take ChatGPT if you're starting from zero, Claude if you write a lot, Gemini if you live inside Google. Use them side by side — that's three free quotas instead of one. And keep in mind that the time you invest in phrasing your requests well pays off more than any change of tool: it's the skill that stays valid when a new model drops next month.
