There is a genuinely usable free plan, a Pro plan at \u20ac15 per month on the annual subscription (\u20ac18 monthly) and a Max plan starting at \u20ac90 per month. The interface is localised.<\/p>\n<p>To plug Claude into the chatbot on your own website, those prices stop mattering: what counts is the API, billed per million tokens. The simulator below works out the real bill, and shows why one little-known technical option, <em>prompt caching<\/em>, cuts the cost by more than half.<\/p>\n<\/div>\n<p>\u201cClaude chatbot\u201d is an ambiguous search. Behind it sit two very different people: the one who simply wants to chat with Anthropic\u2019s AI from a browser, and the one who wants Claude to answer their customers, on their site, using their own content. Both need numbers, and they are not the same numbers.<\/p>\n<p>This article covers both. Every price quoted here was read off the official pages on 31 July 2026, and the screenshots are in the text. Euro to dollar conversion uses the European Central Bank reference rate of 30 July 2026, that is \u20ac1 = $1.1476.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_85 counter-hierarchy ez-toc-counter ez-toc-custom ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Summary<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #3d351f;color:#3d351f\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #3d351f;color:#3d351f\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 eztoc-toggle-hide-by-default' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/botnation.ai\/en\/claude-chatbot\/#What_Claude_actually_is\" >What Claude actually is<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/botnation.ai\/en\/claude-chatbot\/#The_model_line-up_in_July_2026\" >The model line-up in July 2026<\/a><\/li><\/ul><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/botnation.ai\/en\/claude-chatbot\/#Is_Claude_free\" >Is Claude free?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/botnation.ai\/en\/claude-chatbot\/#Claude_in_your_own_language_what_actually_works\" >Claude in your own language: what actually works<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/botnation.ai\/en\/claude-chatbot\/#Claude_or_ChatGPT_the_differences_that_matter\" >Claude or ChatGPT: the differences that matter<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/botnation.ai\/en\/claude-chatbot\/#What_the_shared_conversations_story_really_showed\" >What the shared conversations story really showed<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/botnation.ai\/en\/claude-chatbot\/#The_facts\" >The facts<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-8\" href=\"https:\/\/botnation.ai\/en\/claude-chatbot\/#The_lesson_for_a_company\" >The lesson, for a company<\/a><\/li><\/ul><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-9\" href=\"https:\/\/botnation.ai\/en\/claude-chatbot\/#Plugging_Claude_into_your_website_chatbot_three_routes\" >Plugging Claude into your website chatbot: three routes<\/a><ul class='ez-toc-list-level-4' ><li class='ez-toc-heading-level-4'><ul class='ez-toc-list-level-4' ><li class='ez-toc-heading-level-4'><a class=\"ez-toc-link ez-toc-heading-10\" href=\"https:\/\/botnation.ai\/en\/claude-chatbot\/#1_The_API_directly\" >1.

The name covers both the family of language models and the consumer application built on them: the website, the iOS and Android apps, the desktop app.<\/p>\n<p>That is where the most common confusion starts. When someone says \u201cClaude\u201d, they sometimes mean the product (a chat interface, like ChatGPT) and sometimes the engine (a model you call programmatically). The price is completely different in each case, and that is the first thing to sort out before comparing anything.<\/p>\n<div class=\"bn-def\">\n<span class=\"bn-klabel\">Definition<\/span>\n<p><strong>A token<\/strong> is the billing unit of every language model. It is a fragment of a word: roughly 3 to 4 characters. A page of text weighs about 500 tokens.

Sharing creates a snapshot of the conversation at its own public web address.

Its spokesperson told the press that Anthropic does not share chat directories or sitemaps with search engines, that those share links are neither guessable nor discoverable unless the user distributes them, and that \u201cwhen someone shares a conversation, they are making that content publicly accessible\u201d.<\/li>\n<li><b>Since then<\/b> The results stopped appearing in Google from 28 July.

The Free plan costs \u20ac0 and gives access to chat on the web and mobile apps, web search, memory across conversations and code execution. Usage limits apply and Anthropic does not publish the figures. For occasional use it is more than enough.<\/p>\n<\/div>\n<\/details>\n<details class=\"bn-faq\">\n<summary>How much does Claude cost per month?<\/summary>\n<div class=\"bn-faq-b\">\n<p>For an individual: \u20ac0 on Free, \u20ac15 per month on the annual subscription (\u20ac180 billed up front) or \u20ac18 monthly for Pro, and from \u20ac90 per month for Max. Prices read off claude.com on 31 July 2026, excluding applicable tax. For use inside a product, billing goes through the API and is per million tokens: use the simulator above.<\/p>\n<\/div>\n<\/details>\n<details class=\"bn-faq\">\n<summary>Does Claude work in languages other than English?<\/summary>\n<div class=\"bn-faq-b\">\n<p>Yes. The interface localises automatically and Claude answers in the language you write in. The technical documentation and the pricing page, however, stay in English, and a non-English text consumes more tokens than an equivalent English one.<\/p>\n<\/div>\n<\/details>\n<details class=\"bn-faq\">\n<summary>Are my Claude conversations public?<\/summary>\n<div class=\"bn-faq-b\">\n<p>No, they are private by default. The late July 2026 episode concerned only conversations their authors had explicitly shared by link: those public pages ended up indexed by search engines. A share link makes the content reachable to anyone holding it, including after it has disappeared from search results. Switch the conversation back to private from the share menu to disable the link.<\/p>\n<\/div>\n<\/details>\n<details class=\"bn-faq\">\n<summary>Can I use my Pro subscription for my website chatbot?<\/summary>\n<div class=\"bn-faq-b\">\n<p>No. The Free, Pro and Max plans are individual plans meant for personal use inside the Claude application. Embedding Claude in a product or a website goes through the API, which has its own usage-based billing, or through a platform that supplies the AI layer.<\/p>\n<\/div>\n<\/details>\n<details class=\"bn-faq\">\n<summary>Which Claude model should I choose for a support chatbot?<\/summary>\n<div class=\"bn-faq-b\">\n<p>The cheapest in the range is enough in the vast majority of cases. A support chatbot answers questions whose answer is in your documents: quality depends on selecting the right excerpts, not on the raw power of the model. Move up only if you see reasoning errors, not content errors.<\/p>\n<\/div>\n<\/details>\n<details class=\"bn-faq\">\n<summary>What is prompt caching and why does it change everything?<\/summary>\n<div class=\"bn-faq-b\">\n<p>It is a mechanism that avoids re-billing the fixed part of your prompt (instructions and knowledge base) at full price on every call. The official grid shows, for each model, a cache write rate of 1.25 times the input price and a cache read rate of one tenth of the input price. On a chatbot that resends the same block on every message, the saving often exceeds 50% of the bill.<\/p>\n<\/div>\n<\/details>\n<details class=\"bn-faq\">\n<summary>Can Claude answer from my own documents?<\/summary>\n<div class=\"bn-faq-b\">\n<p>Yes, but not on its own. You have to supply the right excerpts at the moment of the question: that is the principle behind chatbots connected to a knowledge base. The topic is covered in our guide to <a href=\"https:\/\/botnation.ai\/en\/train-chatbot-own-data\/\">training a chatbot on your own data<\/a>.<\/p>\n<\/div>\n<\/details>\n<h2><span class=\"ez-toc-section\" id=\"What_to_take_away\"><\/span>What to take away<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Claude is an excellent work assistant, free for everyday use and \u20ac15 per month for heavy use. That much is settled, and the free plan already answers the question that brings most visitors here.<\/p>\n<p>The second half of the subject is more interesting. Having a generative AI answer your customers is not decided on the price of a subscription but on three things: where the information comes from, who carries responsibility for what the bot says, and what a conversation costs at scale. The simulator gives you the third figure. The first two come down to how you build the bot, not to the model you call.
