Review notes

Context from the listing review and editorial research.

Founded in 2021 by ex-Google engineers Noam Shazeer and Daniel De Freitas, Character.AI has raised about $193M in total funding. In August 2024, Google paid roughly $2.7B in a reverse-acquihire licensing deal, hiring Shazeer, De Freitas, and other researchers back to Google while taking a non-exclusive license to Character.AI's models; the company remains independent. Reported monthly active user figures vary significantly by source, ranging from roughly 20 million to 45 million as of 2025-2026. The platform has also faced notable legal scrutiny and lawsuits related to user safety involving minors.
