How this service works

Takes a recording of up to 120 minutes and the platforms you want, and writes posts for each: a LinkedIn post, an X post or short thread, an Instagram caption, and so on, each within the platform length limit (checked and trimmed here), with fitting hashtags and a reference to the moment in the recording, for clip pairing. Several variants per platform are possible.

Output

A structured response containing one or more drafted posts per requested platform, each respecting that platform's character/length limits, with relevant hashtags, a reference timestamp pointing to the relevant moment in the recording for clip pairing, and up to 3 variants per platform if requested.

Example use cases

Podcast episode to multi-platform posts

“I just uploaded my 60-minute podcast episode to https://mypodcast.com/ep42.mp3 — can you generate LinkedIn and Instagram posts from it in English, 2 variants each, with relevant hashtags and timestamps so I know which clip to pair with each post?”

Webinar repurposed into LinkedIn thought leadership

“I have a 90-minute webinar recording at https://storage.example.com/webinar-oct.mp4, spoken in German. Write LinkedIn posts from it in English with 3 variants, and include hashtags and the moments in the recording each post refers to.”

Interview clip-ready X thread from audio

“Here's a base64 audio file of a 30-minute interview — generate an X thread and a Threads post from it in Spanish, 2 variants each, with hashtags and the recording timestamps so I can clip the right moments.”

When to prefer

Choose this endpoint when you need to repurpose an existing audio or video recording into ready-to-publish social posts across multiple platforms in a single call, especially when platform-specific formatting, length enforcement, hashtag generation, and clip timestamp alignment are all needed together. It is particularly strong for podcast producers, webinar marketers, and content teams who want multi-platform output with variant drafts without running separate transcription and copywriting steps.
