Signal Tools — Enova Studio

Signal Tools turns long audio and video into publish-ready episode pages, right from your browser.

Paste a YouTube link, a podcast (RSS or Apple Podcasts), or upload an audio file, and Signal Tools generates:

• A clean, timestamped transcript (WEBVTT)
• Chapters
• Show notes — summary, key takeaways, highlights, and links

Then send everything to your Ghost site as a draft with one click — title, feature image, audio player, tags, and the original publish date included — ready for you to review and publish.

Built for the Signal Ghost theme, but the transcript, chapters, and notes fit any workflow.

Features
• YouTube, podcasts, and audio files in one place
• Accurate transcription for long episodes (40+ minutes)
• One-click "Send to Ghost" draft
• Runs in a side panel and processes in the background — queue several at once
• Import podcast guests as Ghost contributors
• Bring your own keys — they're stored locally in your browser

You'll need: your own AI API key (Google Gemini, plus AssemblyAI for best transcription) and a Ghost Admin API key to publish. Your keys are only ever sent to those services or your own Ghost site.
