No charge until day 15.
The short answer
The best tool for turning transcripts and recordings into LinkedIn posts is one that extracts multiple moments per recording (not one summary), drafts posts in the speaker's voice from their actual words, and publishes directly to LinkedIn with a human approval step. SparkVox does all of this end-to-end - no separate transcription tool, no copy-paste into a scheduler, no re-prompting after every session.
Any recording you already make
The content is already in your calls and episodes. SparkVox finds it.
Sales calls
Upload or connect Fireflies, Fathom, or Zoom. SparkVox isolates your voice on multi-speaker calls and extracts objections, frameworks, and explanations worth posting.
Podcast episodes
Upload MP3/MP4 or paste a YouTube URL. Choose Host or Guest perspective. Sparky finds the insight-rich segments - not just a summary.
Interviews and trainings
Webinars, board prep sessions, client advisory calls, internal trainings. If you said something worth sharing, the recording is the source.
Existing transcripts
Already have a TXT or SRT file from Fireflies, Fathom, Otter, or Zoom? Upload it directly and skip transcription - straight to moment extraction.
Why other approaches leave gaps
Video clipping tools
OpusClip, Descript, Choppity
Produce short video clips optimised for TikTok and Reels. Do not generate written LinkedIn text posts. Different format, different audience, different channel.
Prompt-based AI writers
ChatGPT, Claude, Taplio, Supergrow
Start from a text prompt, not your recording. No persistent voice profile across sessions. You still need to know what to write before you start - which is the original problem.
Transcription-only tools
Otter, Fireflies, Fathom
Excellent at capturing and searching transcripts. Not built for LinkedIn post generation - you still need to manually extract insights, write a hook, format for the platform, and publish.
From recording to published post in four steps
No separate tools, no file conversion, no copy-paste between apps.
1
Upload or connect your recording
MP3, MP4, TXT, SRT, or YouTube URL. Connect Fireflies, Fathom, Granola, Google Meet, Zoom, and Wispr Flow on paid plans to pull calls directly from the Meetings tab.
2
Sparky extracts moments and drafts posts
SparkVox identifies the publishable segments in your recording and writes one LinkedIn post per moment in your voice - up to 15 posts per project.
3
Review your project's LinkedIn content strategy
Posts are grouped by content theme. Edit hooks, skip weak branches, add a free AI image to any post before approving.
4
Publish to LinkedIn
Approve and publish directly to your LinkedIn personal profile or company page. Post Analytics tracks impressions and feeds the best-performing posts back into future drafts.
Voice profile
Posts that sound like you - because they came from you.
Sparky builds a voice profile from every transcript you process, every edit you make in your project, and the top-performing posts from your Post Analytics. Voice Confidence (0-100) in Settings tracks how much material the profile has learned from.
The difference between a prompt-generated post and a transcript-sourced post is specificity. Your client's situation. Your actual number. Your phrase, not a statistical average of how founders write about leadership.
- Tone and sentence rhythm from your transcripts
- Vocabulary you actually use vs. phrases you avoid
- Storytelling patterns and hook styles
- Corrections from every edit before approval
- Reinforcement from your top-performing published posts
- Brief Sparky context: who you help, topics you own, constraints
