Questions about free tools

Is AnyPost Compose really free?

Yes. Compose is a free online markdown editor — no signup, no API key, and no credits. Drafts save in your browser via local storage until you clear them.

How is Compose different from the live preview?

URL to Markdown and live preview turn a social post URL into clean Markdown (social → Markdown). Compose does the reverse: write markdown, preview platform formatting, and copy text ready to paste into LinkedIn, X, Instagram, and other native composers.

What is the URL to Markdown free tool?

At /free-tools/url-to-markdown you paste a public social post link and get clean Markdown. It uses the same converter and free-tier limits as /preview (ten single-post conversions per day on Starter platforms). It is not for arbitrary website URLs — only supported social post permalinks.

Does AnyPost support rich text on social platforms?

Compose converts markdown bold, italic, and lists into Unicode emphasis and plain lines that work in feeds like LinkedIn and X, plus native markdown where platforms expect it (Reddit, Discord, YouTube descriptions).

Can I save drafts to the cloud?

Guest Compose drafts stay on your device. AnyPost does not require login for Compose. Paid API keys unlock URL conversion features — not the free editor.

What is the llms.txt generator?

It builds a spec-compliant llms.txt index for your domain — site summary, sectioned page links, and copy-ready text for AI crawlers. Optional import from your public sitemap.xml; no signup.

What is the DESIGN.md generator?

It outputs a DESIGN.md design-system file for AI coding agents — colors, typography, UI tokens, spacing, and component rules from a guided form. Copy or download Markdown; no website scan.

What is the XML sitemap generator?

It builds a valid sitemap.xml urlset — paste paths or import URLs from your public sitemap.xml or robots.txt, set changefreq and priority, then copy or download for Google Search Console and Bing Webmaster Tools. No full-site crawl.

What is the JSON-LD extractor?

It finds application/ld+json blocks on a page, lists Schema.org @type values, and copies pretty-printed JSON. Use a public URL fetch, paste HTML, or paste JSON-LD directly — paste modes run only in your browser.
