Built on shared work

Credit where it’s due.

Murmello exists because people share their work. These are the speech models, writing models, and libraries behind the app.

Murmello’s own code is proprietary and is not distributed under an open-source license; see our copyright notice. The components below keep their own licenses. Inclusion does not imply endorsement by their authors.

Speech recognition

• FluidAudio 0.15.6, by Fluid Inference and contributors — Apache 2.0.
• Parakeet TDT-CTC 110M, by NVIDIA and Suno — CC BY 4.0. Core ML conversion by Fluid Inference.
• Parakeet TDT 0.6B V2 and V3, by NVIDIA — CC BY 4.0. Core ML versions by Fluid Inference: V2, V3 and its compact INT4 encoder.
• NeMo text processing, by NVIDIA and contributors, included through FluidAudio — Apache 2.0. FluidAudio’s included license also contains additional upstream notices.

Murmello uses the listed Core ML artifacts without further modifying their weights. The upstream conversions and quantization were performed by the credited providers. Attribution license details: Creative Commons Attribution 4.0.

Optional local writing models

• SmolLM2 360M Instruct, by Hugging Face — Apache 2.0. Uses the official Q8_0 GGUF conversion.
• Qwen3 1.7B, by Alibaba Cloud / Qwen — Apache 2.0. Uses the Unsloth Q4_K_M GGUF conversion.
• llama.cpp, by its contributors — MIT. The app bundles its local execution helper and required libraries from release b10809.

Writing models are optional separate downloads. No model files are hosted on this website. Their licenses and upstream notices are included in the app or linked from the model settings.

Software updates

Native updates use Sparkle 2.9.6, under the MIT license and bundled third-party notices. Its pinned source is included in Murmello’s corresponding-source release archive.

Website and branding

The website’s type is Space Grotesk, by the Space Grotesk Project Authors (license); Lora, by the Lora Project Authors (license); and Geist Mono, by the Geist Project Authors (license). All three are served from this site under the SIL Open Font License 1.1. Murmello’s pods logo and the website’s diagrams, icons and illustrations are original artwork.
