Every week, content creators film, speak, and teach — but Google has no idea they exist. Their ideas stay locked inside TikTok, LinkedIn and Instagram, never indexed by search.

Inkspell turns any YouTube video into a 1,000–1,200 word SEO-optimised blog post that sounds like the creator wrote it. Not AI slop — your actual voice.

Built around Aira Al-Q Sinclair, an AI writing persona trained on how the creator thinks and structures ideas, Inkspell lets users describe their voice through tone chips, sentence style, loves/avoids, and a writing sample. Claude Opus 4.7 then generates a blog post with YAML frontmatter, proper H2 structure, and a concrete CTA — ready to publish.

The transcript is fetched directly from YouTube. The blog post streams back in real time. Enter your API key, paste a YouTube URL, cast your spell.
