PlayHT (PlayAI) was an AI voice generator offering text-to-speech, voice cloning and a developer API, historically priced around $39/month (Creator) and $99/month (Pro) with a limited free tier. Meta acquired the PlayAI team in July 2025, absorbing it into its Superintelligence Labs division; the API went offline within weeks, and the platform was permanently shut down on December 31, 2025, with all accounts, voice clones and audio deleted with no migration path. It no longer operates as a product — this listing exists so readers searching for a PlayHT alternative land on accurate, current information rather than stale marketing copy.
