For years, when I had a question, the first thing I’d do was open my laptop, go to Google, and search for the answer. The problem is that I wouldn’t always find the answer. It wasn’t uncommon to find three articles in the top three search results, each contradicting the others — not exactly trustworthy. Sometimes, you just need someone to explain something simply without all the extra details.
When ChatGPT was released, I found myself on Google a lot less frequently. And now that there are specialized AI question-answering tools, I don’t need to use Google at all.
Ask AI tools can break down complex topics, help with specific problems, and explain things in ways that actually make sense. Most of them are free or cheap, and you can use them whenever you need them.
Here are five AI tools that can answer any question:
1. Overchat AI
Overchat AI Question Answerer is a specialized tool designed to quickly and accurately answer any questions. This tool is different from general AI chatbots because it’s designed to understand your questions and provide clear, helpful explanations.
What makes Overchat AI Question Answerer special is its ability to handle different types of questions in one place. The basic AI model was trained on a lot of data from different areas and can provide detailed answers about almost anything. It’s easy to use. The interface is simple. Ask your question, upload a file if needed, and get your answer. The responses are written in simple language and are easy to read.
You can send up to 50 messages for free each day. If you want to send more, you can pay $4.99 per week to send up to 2,000 AI queries. This basically gives you unlimited access to AI, not just Question Answerer, but all of Overchat AI’s tools, including different AI models for various tasks.
2. ChatGPT
ChatGPT from OpenAI is probably the most well-known AI tool out there. It explains complex topics in simple terms and can handle everything from math problems to essay questions.
ChatGPT’s conversational style is great. You can ask a question, get an answer, and then ask for more details. The free version lets you use GPT-4o, but not GPT-4 mini. This is good enough for most questions. If you want the latest GPT models, you’ll need to pay $20 or $200 per month, depending on the tier. But the free version handles most questions without any problems.
ChatGPT works well with typed questions, but you can only upload 2-3 images per day. This is a big restriction, especially compared to Overchat AI, which allows for up to 50 image uploads daily. If you need help with a worksheet or diagram, you can either describe it in text or upgrade to the paid plan.
3. Claude
Anthropic’s Claude is becoming more and more popular because it provides more detailed and thoughtful responses compared to many other AI tools. The free version of Claude is very powerful because it uses Claude Sonnet 4. Sonnet 4 is a very good, rounded model which genuinely has use when it comes to advanced requests, and people sometimes choose it over the paywalled Opus. This is completely different from ChatGPT. With ChatGPT, you would never choose GPT-4 mini on your own, unless it was to save costs.
When answering questions, Claude’s voice is arguably more empathetic and human-sounding, although this is a subjective measure. Even so, many people like how it talks to them. This is one of the most important things to consider in a question-answering AI. After all, the main purpose of such a tool is to speak to you and answer questions.
Claude is free to use, but there are some daily limits. However, it isn’t as limited as ChatGPT. Once you reach the limit, you’ll have to wait a few hours for it to reset. Usually, it’s about 3 to 4 hours. Unlike ChatGPT, Cladue doesn’t give the option to downgrade to a cheaper model, which could be useful.
4. Gemini
When people talk about Google Gemini, they usually mention it in the context of an AI coder. That makes sense, since Gemini 2.5 Pro is one of the best AI coders available. However, most people don’t realize that Gemini is also a very good question answerer. This is mostly because it understands when it needs to look up facts online, which makes it highly accurate.
Of course, Gemini isn’t the only tool that can look up facts online. Overchat AI, ChatGPT, and Claude can also access the internet. However, if you’ve used ChatGPT or Claude with web search enabled, you may have noticed that they sometimes start a search even when they don’t need to. This makes their answers less accurate and uses up valuable context. Overchat AI doesn’t do this, but it instead relies on you to manually activate the web search.
Gemini is different because as a thinking model it can think for itself when it needs to search for answers online. This is a really cool feature. But beyond this quirk, it’s basically the same as the other tools on this list.
5. Grok
Grok, created by xAI (Elon Musk’s AI company), is currently available through X (formerly Twitter), as well as Overchat AI via the multi-model switcher. It works with X in real time, so you can use it as another way to ask questions on X (and if you want to do that, good luck).
Setting humor aside, this makes it useful for questions about what’s happening now. Grok offers clear explanations, and the latest version, Grok 4, is excellent at math, according to benchmarks.
How to Get the Most Out of AI Question Tools
No matter what tool you choose, to get the best results from any of these tools, be specific with your questions and remember that AI tools are great for explaining things, but aren’t always correct. Double-check the answers, especially if you plan to use them for work or for something important. Otherwise you might end up in the same situation as Thomas Nield, who submitted fake case citations, and as a result, lost his job. “What happened is that Mr Nield cited four cases, but none of them exist.” As the saying goes, trust but verify.
