Why it matters for creators: another fast mover in AI video alongside tools already on our radar (Runway, HeyGen) — worth watching if speed-to-output matters for your workflow.

Security Researcher Exposes a Privacy Flaw in tl;dv

A security researcher disclosed that tl;dv, an AI notetaker for Zoom, Google Meet, and Teams, left 181,874 meeting records across 84,312 users queryable due to a missing tenant-isolation rule. The issue was reported in January 2026 and stayed unfixed for roughly six months.

Why it matters for creators: if you use AI meeting tools, it's a good reminder to check what data these apps store and who can actually access it.
