Questions
Good to know
Which voices do I get?+
Every plan uses our managed AI voices — Chirp 3 HD for natural narration on every plan, plus Gemini Flash for expressive, steerable tone on Pro plans. No setup, no provider accounts to manage.
Do I need an API key?+
No. We handle the text-to-speech provider for you on every plan — there's no key to paste and nothing to configure.
What's the difference between Monthly and Yearly?+
They're the same Pro plan and feature set. Yearly is billed once every 12 months and saves you $45 a year versus paying monthly.
Where can I embed the player?+
Anywhere. A universal embed snippet works on WordPress and any other site or CMS — paste it once and you're done. No plugin required.
What's the character limit about?+
Each plan includes a monthly character cap because we pay the voice provider on your behalf. Free is 10,000 characters/month; Monthly Pro and Yearly Pro are 100,000.
Can I upload my own audio?+
Yes — you can upload an existing audio file instead of generating one, and still get the branded ButterReader player and analytics.
