02 · Overview
Listnr AI and Murmur side by side
Every Listnr AI entry below comes from Listnr AI's official website. Where the site did not say, the table says so instead of guessing.
| Listnr AI | Murmur | |
|---|---|---|
| Pricing model | Free tier plus paid plans | One-time purchase |
| Free tier | Free: 1,000 credits to start, preview 1,000+ AI voices, 142+ languages and accents, Listnr Studio access, no credit card required. | No free trial; 7-day refund |
| Paid plans | Individual: $19 per month; billed $190 annually (monthly billing also offered); Solo: $39 per month; billed $390 annually (monthly billing also offered); Agency: $99 per month; billed $990 annually (monthly billing also offered) | $49 one-time for one Mac, no free trial, 7-day refund |
| Usage limits | Credits are the usage unit, quoted per month: Free 1,000 credits to start; Individual 20,000/month (~2 hours); Solo 50,000/month (~5 hours); Agency 250,000/month (~25 hours). The TTS FAQ states "Each plan includes a monthly credit quota... There is no extra software cap beyond your plan," and that if you run out of credits you cannot generate new audio until the quota resets at the next billing cycle (or you buy extra credits in Listnr Studio). Long scripts are handled by splitting into script blocks/scenes rather than one hard per-request cap. | No character, minute or credit limits |

When to stay with Listnr AI
| Decision factor | What it means |
|---|---|
| You need it on Web, API | Listnr AI lists Web, API support. Murmur is a Mac app only, so it cannot follow you to other devices. |
| You are generating speech from your own software | Listnr AI offers programmatic access for apps and servers. Murmur has a local CLI and MCP server for automation on one Mac, which is not a hosted API for your customers. |
| You want nothing to install or maintain | Listnr AI runs its voices on the vendor's servers, so there are no model downloads and no dependence on your Mac's memory. |
| Your needs fit inside the free tier | The official free tier: free: 1,000 credits to start, preview 1,000+ AI voices, 142+ languages and accents, Listnr Studio access, no credit card required. If that covers you, there is no reason to pay for anything. |
05 · Highlights
When Murmur is the better fit
| Decision factor | What it means |
|---|---|
| Your scripts are private or unreleased | Murmur generates on your Mac, so client scripts, manuscripts and drafts are not uploaded for synthesis. |
| You generate a lot of audio | Listnr AI charges through free tier plus paid plans. Murmur is $49 once with no character limits, so long audiobooks and repeated retakes cost nothing extra. |
| You produce finished audio, not just listening | Murmur is built around projects: multi-speaker scripts, per-line retakes and WAV or M4A export for editors such as Final Cut Pro, iMovie and Logic. |
