What Lefty doesn't read: the actual content of a creator's videos.

Lefty is an influencer CRM that manages campaigns, tracks performance, and analyses creator audience data. What it doesn't do — and that's not its purpose — is read a creator's YouTube videos before you sign a partnership. Unsaid does: every sponsor across all their videos, undisclosed partnerships, legally regulated categories. Two different tools, for a complete picture.

Campaign management and content audit: two distinct questions

For a brand working with YouTube creators, the questions don't arise at the same time:

  1. How do we manage our influencer programme? Finding creators, contacting them, tracking campaign performance, measuring ROI. That's what Lefty does.
  2. Who are we actually partnering with? Have they promoted a direct competitor on YouTube? Did they disclose past partnerships? Are their topics compatible with our brand? That requires reading their videos. That's what Unsaid does.

These two questions don't share a tool. Lefty manages creator relationships and campaigns — reading published video content is not its mission. Unsaid reads that content and doesn't manage campaigns.

French influencer law and YouTube creators

The French law of 9 June 2023 (n° 2023-451) established joint liability between advertisers and influencers. A French brand can be held liable for content published by a creator they paid, even for videos predating the partnership, if that content covers regulated categories: gambling, financial products, dietary supplements, cosmetic surgery.

Lefty measures a creator's audience and tracks campaign performance. It doesn't read YouTube video content. Unsaid reads every video automatically and flags regulated categories.

The report opens on a private, non-indexed link, and can be printed or saved as PDF for the partnership file. The audit reads all of a creator's YouTube videos (up to 200) in one minute, from the marketing team's computer.

What it isn't

Not a legal opinion, not a judgment of the creator: an automated reading of what is public, to be verified, replacing dozens of hours of manual viewing. YouTube only for now.

The first audit is free, on a creator of your choice. Send us their YouTube channel name: you'll receive their audit the same day.
