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 original code is licensed under GNU GPL version 3 only. 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.

Website and branding

The interactive 3D scene uses Three.js 0.185.1, by its authors and contributors, under the MIT license. The library is bundled and served locally with Murmello’s original scene code. Its original library source and Murmello’s scene source and dependency lockfile are available to download and rebuild.

The website uses system fonts, original interface illustrations, and Murmello’s own speech-mark artwork. The live sculpture is built from that logo’s vector geometry. The fallback mint illustration was generated with an image-generation tool using Murmello’s logo as a reference. Interactive dictation scenes are illustrative examples, not live microphone recordings. The settings images are screenshots of the actual app.
