AI chatbots have become an integral part of our everyday lives. And while ChatGPT has become synonymous with AI, we’ve seen the growth of several chatbot platforms, including Gemini, Claude, Le Chat, and Grok.
You may be wondering which chatbot is the best to use on a free plan? These services can perform multiple tasks, bit they also come with limitations unless you upgrade to their subscription offerings. For those looking to save some money, I recently experimented with the five biggest chatbots to test both their abilities and restrictions. Here’s my top pick.
ChatGPT
ChatGPT is hands-down the most well-known chatbot. If you want assistance with everyday tasks, like planning a travel itinerary or constructing a workout plan, the free plan will readily assist.
Also, by accessing the GPTs section, you’ll be exposed to a range of custom-made chatbots that perform a specific function. Such examples include Write For Me, where you can compile essays, business plans and/or blog posts. You’ll also have direct access to fundamental AI tools, like deep research and study & learn, to assist you with the odd homework task and access to Google Drive.
So what are the free plan’s limitations? As a simplified version of ChatGPT, its premium features will be unavailable to users unless you upgrade to the platform’s Plus or Pro Plan. For example, while the free plan enables you to generate images, video creation is inaccessible.
Custom GPTs are freely available, bit the free plan doesn’t allow you to create your own without a subscription. Anyone looking to exploit the Codex agent will have to pay extra, too.
Ultimately, though, I wouldn’t let these shortcomings prevent you from using the free ChatGP plan. It may feel frustrating that certain features on the free plan, like Deep Search, take much longer to produce results. Also, you may find the occasional hallucination in your search results and the search limit in your prompts to be inconvenient.
However, the limited access you do have to ChatGPT-5 provides you with the fundamental basics for you to exploit on a daily basis.
Gemini (2.5 Flash)
For those interested in custom GPTs explained earlier, the free Gemini (2.5 Flash) plan follows a similar, yet reduced, model with its appropriately titled ‘Gems’ section.
Need assistance with improving your career prospects? Give the career guide section a click. Or are you looking for a learning support tool? The learning coach gem will be your oracle. You’ll find fewer Gems than custom GPTs in comparison, but more than enough to assist you with various day-to-day tasks.
Content creation remains a limited feature on the free version of Gemini, with image creation available but not videos. A subscription to Gemini Pro also provides users with NotebookLM, a research tool with 5x the limit in its search capabilities.
Another benefit of Gemini is its direct access to Google Workspace. Those who want a quick summary of their content from apps such as Gmail, Google Drive, and Docs will be happy. This also extends to Google’s travel service such as Flights, Hotels, & Maps. It’s certainly a quick fix for those who’d prefer not to spend time searching the wider web.
While Gemini Pro affords you greater depth with your projects, such as the ability to understand large books and reports with 1,500 pages of file uploads, the free Gemini plan still offers users a wide array of helpful options.
Grok
Do you need to speak to a chatbot that has a certain voice? Then you’ll want to use Grok’s basic plan and check out its personas section. Through this, you can speak with Grok as if it were a companion, loyal friend or homework helper, among others.
Think of it as less of a genuine connection and more of a platform that tailors its responses to the needs of a diverse audience. I found this to be an interesting addition to the chatbot.
What the free Grok plan lacks is unlimited use of its search engine, including DeepSearch and think mode. Your search usage is limited to 10 prompts every 2 hours.
A subscription to SuperGrok and/or SuperGrok Heavy would grant you enhanced access to Grok 3 and Grok 4 (the latest model) and subsequently higher usage limits for features like DeepSearch and image generator. SuperGrok will also allow you to create an AI companion that isn’t available on the free plan.
But if you’re able to put up with a slightly longer wait time for programs like DeepSearch and image generator, then this will still be a useful chatbot to assist you.
Any regular news readers will also be happy to know that Grok has a dedicated news section (latest news) that filters the top international news stories without having to insert a series of precise instructions into the chatbot.
Overall, while Grok provides similar functions to other chatbots, I found its free plan to be significantly more limited in that it doesn’t contain a section for additional GPTs or Gems. A subscription might be your best bet.
Le Chat
Those who visit Le Chat’s free plan will be missing out if they don’t take advantage of its agents section. Here users will find tools including personal tutor, global summarizer and writing assistant.
Think of these tools as a quick fix for those who need to summarize extensive documents, refine their writing abilities or need a personalized learning companion. Do take into account the document size as larger ones will require you to pay.
One key feature of Le Chat is its Flash Answers setting. This feature enables users to type your request into the chatbot and get high speed replies. Though do be aware that you have a limited number of prompts available and will have to upgrade for the Pro or Team plan to receive up to 250 flash answers a day.
Le Chat’s free plan does not, unfortunately, allow you to connect to Google Workspace. I would advise downloading assignments you plan on scrutinizing via Le Chat as PDFs onto your system before uploading them to this chatbot for inspection.
There is definitely room for expanding the number of agents available, but overall Le Chat is worth a look. Le Chat also maintains a deep research tool. But be aware of how often you use it as you are limited to five prompts until the system resets itself.
Claude
When using AI chatbots, is it purely for education, work, and/or general convenience? I find that certain chatbots can also offer an outlet to be creative and have a bit of fun for free. Claude’s free plan is one of these options. More specifically, Claude’s artefacts section has enough categories to leave users content.
Claude’s learn something section offers education resources like origin stories and language learning. Alternatively, users can take advantage of the like hacks category where they will be treated to instruments like Claude’s email writing assistant.
Aside from this, the free plan maintains the essential features that come with other chatbots, including conversations, coding support, text generation and analyzing content.
Your daily message limit is not clearly established but rather based on the demand at the time. which could be troublesome if users aren’t aware of the number of prompts they have left. An upgrade to Claude Pro or Max will mitigate this.
Claude may lack video and image generation and the ability to connect to Google Workspace without an upgrade, but you can easily accomplish a great deal in a single day using this platform.
Which free AI chatbot is best?
So, if you’re not willing to part with your hard-earned cash, which free AI chatbot is best for you?
Arguably, ChatGPT has the best overall package. It offers a lot of the same features found on its paid versions, just with limits in place. If you are mainly using AI to ask questions, research, and occasionally make an image or graph, ChatGPT’s free version has all you need. Just keep in mind that you’ll need to pay for features like advanced thinking capabilities and video generation.
Equally, Gemini crams a lot of features in without asking you to pay. You can do a lot of the same stuff as you can with ChatGPT’s free plan, as well as use helpful tools like NotebookLM. Both Gemini and ChatGPT arguably offer the most capable interaction without you having to pay.
So, should you skip Le Chat, Claude or Grok? These tools do have their benefits. Grok will especially appeal to users who like their chatbot with some personality, or anyone who is using the tool for coding.
Le Chat’s biggest benefit is its fast searches, but outside of that, it might feel limited compared to its competitors. And Claude, like Gemini and ChatGPT, simply offers a limited version of its full service, while lacking functions like memory and image generation.
Overall, you can’t go wrong with any of these free AI tools. However, ChatGPT and Gemini are our clear recommendations.
