X17b · Open source · Product & web
X17b turns any Substack post into clean, portable Markdown and audio, and pays authors. We designed and built the extraction tool and its creator-payout model.

90%
of fees to verified authors
Paste a Substack article or publication URL to extract clean Markdown plus the post's audio narration; publication URLs let you batch-select posts. A verified-author program routes 90% of fees to authors who connect a BSV wallet, good for readers who want portable copies and authors who want to monetise.
We designed and built the product end to end, the extraction flow, the verified-author program, and the payments that make it fair.
