Does SparkVox train public models on my transcripts?

SparkVox uses commercial AI APIs for transcription and drafting. Your data is not used to train public models. Voice profile learning stays tied to your account from material you upload and edits you make in the app.

Can I upload TXT or SRT instead of audio?

Yes. Upload transcripts from Fireflies, Fathom, Otter, or Zoom when you already have text. You still review every draft before anything publishes.

What if a draft mentions something private?

Edit or skip the branch before approving. Nothing publishes without your confirmation. Many strong posts use the lesson without naming the client or quoting sensitive numbers.

Is it safe to put your sales call transcripts into an AI tool?

Direct answer

It is safe when you control what goes in and what goes out. Your calls are often already recorded and transcribed by Zoom, Fireflies, Fathom, or Otter before any content tool sees them. The real protection is procedural: do not process genuinely confidential calls, review every draft before publish, and post the insight rather than client-specific details. SparkVox never auto-publishes - you approve each post after editing - and voice learning stays in your account from transcripts you upload, not from scraping LinkedIn.

The decision starts before the content tool

If you use a meeting notetaker or Zoom cloud recording, your conversation is already in a third-party system and often already summarized by AI. Putting a transcript into a LinkedIn content tool is a second step on material you may have already shared with vendors. The confidentiality question is which conversations are appropriate to turn into public posts, not whether AI can see text at all.

What actually protects you

Skip calls that are truly confidential - M&A, sensitive HR, named client strategy you would never repeat in public. For everything else, treat drafts like any other pre-publish content: anonymize names and numbers, share frameworks instead of incidents, and reject anything that reveals what was meant to stay private. Human review before publish is the control that no filter can replace.

What to verify in any tool

Confirm human-in-the-loop publishing, official LinkedIn API access (not password scraping), clear privacy and security documentation, and your ability to delete projects you no longer want stored. Tools that auto-comment or auto-post without approval add account risk on top of data risk.
