Our tool has been trained on millions of problems and solutions ranging from organic chemistry and protein structure to chemical reactions and beyond, to help students solve their homework tasks without stress.
Overchat AI not only provides the solution, but also offers a structured, step-by-step explanation of the problem. Answers generated using a machine learning algorithm are highly accurate, with a success rate of 99.9% for school and college-level chemistry questions. Overchat AI offers the best AI tool for chemistry homework for free.
Problem solving has never been more accessible. Solve as many chemistry problems as you need with this free online tool — there's no catch!
Don't just get the answers — learn how to solve the task so that next time, you can do it yourself, including in live exams where access to AI is limited — all thanks to the detailed problem breakdowns.
Benefit from the power of AI help. Ask questions about chemistry in plain English and receive accurate, easy-to-understand answers to complex topics.
With Overchat AI, you have three options for getting started: you can copy and paste the problem question as text, upload a screenshot of the homework or draw on an interactive canvas with a pencil.
Click Get Answer and wait 30 seconds for the AI to process your submission, analyse the problem and prepare a solution you can use, along with a structured, step-by-step breakdown of the problem.
All done! Receive a detailed solution from our AI machine learning system for free. Copy and paste it, or dive into the breakdown to understand the reasoning.

Overchat AI brings you the power of the world's top AI models: ChatGPT, Claude, Gemini, Mistral, and more.
Overchat AI gives you access to multiple AI models including ChatGPT, Claude, and Gemini in one place. You can compare answers across models, upload images of chemistry problems, and get explanations for everything from balancing equations to organic synthesis.
It's an AI that can read chemistry problems (typed or photographed), solve them, and explain the steps. It handles things like stoichiometry, molar mass calculations, reaction balancing, Lewis structures, and organic mechanisms.
General chemistry, organic chemistry, biochemistry, physical chemistry, and analytical chemistry. This includes balancing equations, calculating molar mass, drawing structures, predicting reaction products, and working through thermodynamics problems.
Yes! You can use our chemistry solver for free. It's unlimited and doesn't require you to sign up. There's no catch, no free trial and no restrictive limits.
Chinese company Baidu has quietly released a model that's just as good as DeepSeek and ChatGPT — ERNIE 4.5 delivers exceptional performance at a fraction of the cost — and most people outside China have never even heard of it.
If you're wondering: what is DeepSeek AI, the answer is quite simple. DeepSeek AI is a Chinese AI research lab that builds large language models. The company released several models in late 2024 and early 2025 that compete directly with OpenAI's GPT-4 and Anthropic's Claude, but at a fraction of the operating cost.
ChatGPT Plus costs $20 per month plus tax, while the Pro plan costs $200 per month plus tax. Understandably, not everyone is willing to pay that much for a chatbot, especially if the premium features aren’t worth it to them. This raises an obvious question: how can I use ChatGPT for free?
