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.
