A final cut.
The creative decisions stay together.
So the next revision starts where you left off.
Keep the direction in the dialogue.
Write in blocks, assign the speaker, and add expression tags where the delivery needs a little direction.
Regenerate a block when the line changes—not the entire script. Expression-tag support depends on your model.

Murmur for Mac$49USD · one-time purchase
One purchase. One license for one Mac.Get Murmur Applicable taxes shown at checkout.License & update policyKokoro is bundled for basic text-to-speech. Optional models for cloning, Voice Design, and other speech features require at least 16 GB of unified memory and additional model/runtime downloads. For example, the app estimates about 1.7 GB for Qwen3-TTS Base and 2.3–4.5 GB for Voice Design, depending on the variant. These are model downloads, not total installation sizes: allow additional free space for runtimes, setup, and generated audio. Total disk space needs and generation speed vary by model and your Mac.
Is Projects included with Murmur?
Yes. Projects is a workspace in the Murmur Mac app, not a separate product or add-on subscription. One purchase provides one license for one active Mac.
Your purchase includes perpetual access to the version you buy and free updates for that version. Future versions and upgrades are not guaranteed.
Can I change one line without generating everything again?
Yes. You can regenerate individual script blocks, then review and arrange the resulting clips on the timeline. Editing text alone does not create new audio; generate the changed block in the app.
Which voices can I assign to a speaker?
Choose a voice supported by the project's selected model. Kokoro has built-in preset voices; compatible cloning models can use saved reference profiles. Model support, transcript requirements, and voice permissions vary.
Does it work without the internet?
Speech generation runs locally after setup. Internet access is needed for activation and periodic license validation, model downloads, updates, and community voice browsing. Projects does not upload your script to a cloud service for generation.
What can I export?
Export the script's timeline mix as WAV or M4A. You can also include a text transcript, separate clip files, and a CSV of chapter markers when you have added markers to the timeline.
