What is Explain Anything?
Explain Anything is a free AI conversation tool that takes something confusing (a contract clause, a scientific concept, a piece of code) and explains it in plain English. Your message is routed to whichever conversational model answers it best that moment, and you get clear, sourced responses and structured thinking on any topic back in seconds without picking a model yourself. There is no account to make and no email to hand over; once the tab closes the conversation is gone.

- ✦Each message routes to the model best suited to answering it
- ✦Conversations vanish when the tab closes; nothing is kept
Models: It routes across leading models including Gemini, Llama and Mistral families, picking the best available one per request. The exact model used is shown after every response.
See it in action
A first-time tenant hits an indemnity clause in a rental agreement and can't tell if they're signing away something serious.
What you type
Explain this lease clause in plain English: "The Tenant shall indemnify and hold harmless the Lessor against all claims, liabilities and costs howsoever arising from the Tenant's use of the Premises."
What you get
In plain terms: if someone gets hurt or something goes wrong because of how you used the place, you agree to cover the landlord's costs rather than them. "Indemnify and hold harmless" = you take on the financial responsibility. "Howsoever arising" is deliberately broad — it isn't limited to your fault alone, which is the part worth querying. A common ask is to narrow it to claims caused by your negligence or breach, not "all claims" full stop. This is general explanation, not legal advice — worth a tenancy service's eyes before you sign.
Tip: Paste the exact wording rather than paraphrasing — a single word like "howsoever" or "gross" changes what you're agreeing to, and it can only flag what's actually on the page. Tell it what you're worried about and it'll point you to the specific phrase to negotiate.

How it works
- 1Start typing, a question, an idea, or something to work through.
- 2Your message is routed to the conversational model best suited to it.
- 3Read the answer and keep the conversation going; context holds for your session.
Tips for the best results
- Paste the confusing thing in full rather than describing it, because the exact wording usually matters.
- Say who the explanation is for, whether a beginner, a specialist, or a ten year old.
- Ask for an analogy or a worked example if the plain definition still refuses to stick.
- If one explanation misses, ask it to try a completely different angle rather than just rephrasing.
FAQ
Frequently asked questions
Can I paste in a contract before I sign it?
You can. It's one of the most common uses. It will translate the clauses into plain English so you know what you're agreeing to and flag anything worth a closer look. What it can't do is tell you whether to sign. A plain English explanation isn't legal advice, so for a high stakes agreement put a lawyer's eyes on it too.
How do I get an explanation pitched at the right level?
Say who it's for. 'Explain this to someone who's never studied chemistry' lands differently from a bare 'explain this'. If the first pass is still dense, reply with the exact sentence that lost you rather than asking for the whole thing again. If it overshoots into baby talk, ask it to step back up a level. It adjusts quickly.
Does it handle code, or just written documents?
Code is squarely in scope. Paste a function, a regex or a chunk of legacy spreadsheet formula and ask what it does, line by line if you want. It's especially handy for code you've inherited with no comments and no author left to ask. One habit worth keeping, test its reading against actual behavior before you change anything it explained.
What if the thing I paste is full of jargon from a really specialized field?
It copes better than you'd expect with mainstream professional jargon, legal, medical, financial, technical. Genuinely obscure specialties are shakier ground, because there's less for it to draw on, so an explanation can sound fluent while missing what a term really means inside that field. When the stakes are high, cross check the key terms against a source from within the field.
Is it OK to paste a document with my personal details in it?
Everything you paste goes to outside AI providers just long enough to build the explanation, then disappears when the tab closes. Nothing sits in an archive on the site and nothing feeds a training set. Still, the low effort option is to blank out names, addresses and account numbers before pasting. The explanation will be exactly as good without them.
Is there a free AI that explains things in simple terms with no sign up?
Yes. Paste anything confusing and get a plain-English explanation for free, with no account or email needed. It handles clauses, concepts, jargon and code. There is nothing to install, so you can drop in a puzzling passage the moment you hit one.
Can it explain a math problem or formula step by step?
Yes. Paste the problem or formula and ask it to work through each step and explain the reasoning as it goes. It is a strong way to see how an answer is reached, though you should check the final figures yourself for anything important.
Can it give me a real-world example or analogy?
Yes. If a plain definition will not stick, ask for an everyday analogy or a worked example and it will ground the concept in something familiar. Asking for two or three different analogies often makes an abstract idea click faster than one alone.
What are the usage limits?
Text chat is unmetered during the current free launch phase, no daily message cap, just a short per-minute limit that stops automated abuse and that normal conversation never reaches. Paid plans with higher limits and priority model access are coming soon.
