sayer

Your words, spoken.

High-quality text-to-speech synthesis with custom voices, powered by Lightning micropayments. Paste your text, choose a voice, pay a few sats, and download your audio.

How It Works

✎

1. Write

Paste or type the text you want spoken. Markdown, plain text, long-form articles — sayer handles it all.

♫

2. Choose

Pick from available voices or upload your own. A 30-second WAV sample is all it takes to clone a voice.

⚡

3. Pay & Play

Pay a Lightning invoice — a few sats per chunk of text. Download your MP3 or play it right here.

Voices Vended

Drop in a few sats, pick your voice, collect your audio. No accounts, no subscriptions, no middlemen — just a vending machine for speech. Sign with your Nostr key, pay over Lightning, and walk away with your MP3.

Wire Up Your Agent

Integrate text-to-speech into your own applications using the sayer REST API. Authenticate with your Nostr keypair via NIP-98, submit text, pay with Lightning, and download audio — all programmatically.
