What can you convert to a mind map?

SpawnGraph's conversion pipeline handles any text-bearing content. Paste raw text, drop a file, paste a URL, or drop a YouTube link. The browser-native NLP engine detects structure — headings, sub-headings, lists, paragraphs — and organises it into a hierarchical mind map you can edit, share, or export.

For file imports, SpawnGraph reads the text layer directly in your browser. Your files are never uploaded to a server. For URL and YouTube imports, a lightweight proxy fetches public content and the NLP still runs client-side — nothing is stored.

Common questions

What file formats does SpawnGraph support?
93+ formats including PDF, Word (.docx), Excel (.xlsx), PowerPoint (.pptx), Google Docs exports, Markdown (.md), EPUB, CSV, OPML, TXT, JSON, images, and audio transcripts. URLs and YouTube videos are also supported.
Are the tools free?
Yes. All converters are free, no signup required to try. The free plan supports unlimited conversions from text, URLs, and files.
Is my content uploaded to a server?
Text, PDF, and file conversions run entirely in your browser — your data never leaves your device. URL and YouTube imports use a lightweight server fetch to retrieve public content, but NLP structuring still runs locally.
