Free Online Tools for SEO, Domains, AI & Productivity

SEO & Website Tools

Sitemaps and robots.txt are how a site tells search engines what exists and what to ignore, so most crawl and indexation problems show up here first. These tools cover the whole loop: find the sitemaps a site actually publishes, validate their XML, generate or split one that is too large, extract the URLs inside it, compare two versions to see what changed after a release, and derive robots.txt directives from it. The audit and URL-extraction tools work at the page level instead, for when the question is what a site contains rather than what it declares.

• Open Sitemap Finder & CheckerEnter a domain and we’ll read its robots.txt, probe the usual locations, and report every sitemap we find — whether it’s valid, and how many URLs it holds.
• Open Sitemap ValidatorCheck a sitemap against the sitemaps.org spec. Every error and warning, explained — plus the things that are technically valid but almost certainly not what you intended.
• Open XML Sitemap GeneratorWe crawl your site (same-origin links, robots.txt respected) and emit a valid XML sitemap you can download or copy. Free tier caps the crawl so it stays polite.
• Open Sitemap Index GeneratorPaste a list of sitemap URLs and get a valid <sitemapindex>. Optionally fetch each to fill in lastmod.
• Open Sitemap URL ExtractorPull a flat, searchable, exportable list of every URL in a sitemap. Sitemap indexes are expanded automatically, so you get the pages — not a list of other sitemaps.
• Open Sitemap URLs Comparison ToolDiff two sitemap versions to see what was added, removed, or had its lastmod changed. Ideal for spotting accidental drops after a deploy.
• Open Sitemap Split/Merger ToolBreak a large urlset into files under the 50,000-URL limit and get a sitemap index that ties them together. Tell us where you’ll host the children so index locs are absolute.
• Open Sitemap Analytics & InsightsDepth distribution, path segments, freshness, priorities, changefreq, duplicates, and actionable recommendations — not just charts.
• Open Sitemap Frequency AnalyzerDistribution of changefreq and priority values, plus anti-patterns like identical priorities or “always” on stale pages.
• Open Sitemap to Robots.txt GeneratorBuild a robots.txt with Sitemap directives and common Allow/Disallow rules — including toggles for GPTBot and CCBot. Runs entirely in your browser.
• Open Full Site SEO Audit & CrawlerCrawl a full website to extract SEO metadata, headings, word counts, internal/external links, missing alt attributes, and detect broken pages. We save the results so you can review them later.
• Open Website URL ExtractorStart from a homepage and discover every same-site link — no sitemap required. Respects robots.txt, rate-limits politely, and caps the crawl so it stays safe on a public tool. Best on server-rendered HTML; JavaScript SPAs may return few links.

Useful if you are auditing a site before acquiring its domain, or checking your own after a migration.

AI Chat & Text Tools

These tools answer questions against a source you supply rather than against general knowledge, which is what makes the answers checkable. Pick the one matching your input: pasted text, a live URL, a PDF, a Word file, or a generic document. The workflow is the same in each case — the source is parsed, then you ask questions about it — but the parsing differs enough that the right starting point matters. Use them to interrogate a long report, pull specifics out of a contract, or summarise a page without reading all of it.

• Chat with AI Chat with Your Text DataPaste text, then ask questions. Answers stay grounded in what you pasted.
• Chat with AI Chat with Your Website DataPaste a site URL — we crawl same-origin pages (bounded), index the content, then answer questions grounded in those pages.
• Chat with AI Chat with Your Document & DataUpload PDF, DOCX, HTML, or text — or paste — then ask grounded questions.
• Chat with AI Chat with Your PDF Document & DataUpload a PDF and ask questions. Answers are grounded in the document text.
• Chat with AI Chat with Your Word Document & DataUpload a .docx and ask questions grounded in the document.

Best suited to documents you already have and need answers from, rather than open-ended research.

AI Prompt & Writing Tools

Two related jobs sit here. The prompt tools help you get better output from any AI model: the generator builds a structured prompt from a rough intent, and the optimizer rewrites one that is producing weak results. The writing tools draft a specific artefact instead — a reply, an answer, an email response, a letter, a blog title, or a customer-service script. Choose by output type: if you need a better instruction, use the prompt tools; if you need finished text, use the writing tools.

• Open Best AI Prompt GeneratorDescribe your goal and get a ready-to-use prompt with a recommended framework (RTF / CRISPE / RACE).
• Open AI Prompt OptimizerPaste a prompt and get a clearer, stricter version plus a list of what changed.
• Open AI Reply GeneratorPaste a message and get 3 ready-to-send reply variants.
• Open AI Answer GeneratorAsk a question and get a full answer with key points.
• Open AI Email Response GeneratorPaste a received email and get a subject + body ready to send.
• Open AI Letter GeneratorPick a letter type, add details, and get a complete draft.
• Open AI Blog Title GeneratorEnter a topic (and optional keyword) and get 10 title options with short rationales.
• Open Customer Service Script GeneratorDescribe a support scenario and get a dialogue script plus alternate lines.
• Open AI Chatbot Conversation AnalysisPaste a transcript and get summary, sentiment, gaps, failed intents, and recommendations.

The conversation-analysis tool is the diagnostic counterpart, for reviewing chat transcripts after the fact.

Domain & Brand Naming Tools

Naming and domain availability are the same problem in practice: a name you cannot register is not a name you can use. These generators produce candidate names for a SaaS product or a chatbot, which is the step before checking what is actually available. Good candidates are short, easy to spell aloud, and unambiguous when typed — the same criteria that make a domain memorable.

• Open AI SaaS Brand Name GeneratorDescribe your product and get brandable names with domain hints.
• Open AI Chatbot Name GeneratorGet distinctive chatbot name ideas matched to industry and personality.

Once you have candidates, check what is available with AI domain search, compare a whole shortlist at once with Bulk Domain Search, and decide which extension fits using the TLD list. New to this? Start with the beginner's manual.

File & Format Conversion Tools

Markdown is the practical lowest common denominator for text you intend to reuse — it survives copy-paste, diffs cleanly in version control, and imports into most publishing tools without carrying styling over. These converters take the formats content usually arrives in and produce Markdown: PDF, DOCX, RTF, HTML, CSV, JSON, XML, a live webpage, a Notion page, a Google Doc, or just pasted rich text. Pick by source format; the output is consistent across all of them.

• Convert Convert PDF to MarkdownUpload a PDF and get clean Markdown. Works best with text-based PDFs — scanned image PDFs need OCR, which we don’t support yet.
• Convert Convert DOCX to MarkdownUpload a .docx and get Markdown with headings, lists, and links preserved. Old .doc files aren’t supported — save as .docx first.
• Convert Convert HTML to MarkdownPaste HTML or upload a file and get clean Markdown — scripts and styles are stripped automatically.
• Convert Convert RTF to MarkdownUpload or paste Rich Text Format and get Markdown. Best-effort conversion for common formatting (bold, italic, paragraphs).
• Convert Convert CSV to MarkdownPaste a CSV or upload a file and get a Markdown table you can drop into docs, READMEs, or Notion.
• Convert Convert JSON to MarkdownTurn JSON into a readable Markdown table or nested list. Arrays of objects become tables; nested objects become bullets.
• Convert Convert XML to MarkdownPaste XML or upload a file. RSS and Atom feeds become clean tables; everything else becomes a nested Markdown list.
• Convert Convert Webpage to MarkdownPaste a URL and we’ll fetch the page, strip navigation chrome, and return the main content as Markdown.
• Convert Convert Notion to MarkdownPaste a public Notion share link (Anyone with the link). Private pages and some database views aren’t supported.
• Convert Convert Google Docs to MarkdownPaste a public Google Docs link (Share → Anyone with the link can view). We export it as HTML and convert to Markdown.
• Convert Convert Paste to MarkdownCopy from Word, Google Docs, or a webpage and paste here. We read the HTML clipboard flavour and turn it into Markdown.

Most useful when migrating documentation or moving content out of a tool that exports awkwardly.

FAQ & Documentation Tools

An FAQ is worth writing when the same questions recur and the answers already exist somewhere less accessible — a support inbox, a policy document, a long product page. These tools read a source you supply and draft question-and-answer pairs from it, so the FAQ reflects what the document actually says rather than what you remember it saying. Choose by where the source lives: a PDF, a webpage, a DOCX, raw HTML, a Google Doc, or Notion.

• Generate FAQ from AI FAQ GeneratorPaste a topic or source text and get Q&A pairs you can publish.
• Generate FAQ from Website FAQ GeneratorEnter a site and we pull key pages (home, about, FAQ, pricing…), then turn them into grounded Q&A plus JSON-LD FAQPage markup.
• Generate FAQ from PDF to FAQ GeneratorUpload a PDF and get Q&A pairs grounded in the document, plus one-click FAQPage JSON-LD.
• Generate FAQ from Webpage to FAQ GeneratorPaste a URL — we extract the main content and generate grounded FAQ pairs with JSON-LD export.
• Generate FAQ from DOCX to FAQ GeneratorUpload a .docx and get FAQ pairs grounded in the document, ready for FAQPage rich results.
• Generate FAQ from HTML to FAQ GeneratorUpload or paste HTML and get grounded FAQ pairs plus FAQPage JSON-LD.
• Generate FAQ from Google Docs to FAQ GeneratorPaste a shareable Google Docs link. The doc must be publicly viewable (or “anyone with the link”).
• Generate FAQ from Notion to FAQ GeneratorPaste a public Notion page URL and get grounded FAQ pairs with JSON-LD export.

Always edit the output before publishing. Search engines only credit FAQ content that is genuinely visible and answers a real question, and a generated draft will include some that are neither.

Productivity & Business Tools

Two standalone utilities that do not belong to the larger clusters: an ROI calculator for modelling whether a chatbot is worth deploying, and an email signature generator for producing consistent signature markup across a team.

• Open Chatbot ROI CalculatorModel hours and cost saved from ticket deflection. Results stay in the URL so you can share them. Runs entirely in your browser.
• Open Email Signature GeneratorCreate a Gmail/Outlook-friendly signature with table layout and inline styles. Copy HTML ready to paste. Runs entirely in your browser.
