Perplexity TTS

About

Listen to Perplexity.ai answers instead of reading them. Perplexity TTS adds a "Listen" button to every answer and reads it aloud using your own text-to-speech provider.

Key features
• Multi-provider — OpenAI, OpenRouter, and ElevenLabs, each with its own API key (stored locally, one per provider).
• Any model, any voice — editable Model and Voice fields with suggestions, so every model the providers offer works (including new ones). ElevenLabs models and voices are loaded live from your account.
• Low-latency streaming — audio starts after the first sentence while the rest is still being generated.
• Live read-along — optionally reads each new answer automatically, sentence by sentence, while Perplexity is still writing.
• Clean speech — strips citations, code blocks, markdown, and the "Related questions" section before reading.
• Adjustable speed, mini-player with progress bar, and a one-click stop.

Privacy
The answer text is sent only to the text-to-speech provider you choose, to generate the audio. Your API keys are stored locally in your browser (chrome.storage.local), one per provider — never synced and never sent to anyone else.

You need your own API key from OpenAI, OpenRouter, or ElevenLabs. Usage is billed by that provider, not by this extension.

Permission justifications
• storage — saves your settings and API keys locally.
• host: www.perplexity.ai — inject the Listen button and read the answer text (content script).
• hosts: api.openai.com, openrouter.ai, api.elevenlabs.io — send the answer text to the selected TTS provider to generate audio (service worker).
