Watch the full recording with sound (about 4 minutes, recorded on Windows from a real run; History text is blurred).

• Dictate with a keyboard shortcut and keep a searchable transcript history.
• Transcribe what your computer plays, such as a meeting or a video, as it is heard. Grey provisional text keeps up with the speech, and a small floating window shows the transcript without opening Inaudio.
• Pick the source: system audio, system audio with your microphone, or one audio device such as a virtual cable.
• Clean up noise on the device: a voice detector skips stretches without speech, and an optional speech cleanup model filters background noise.
• Read text or your clipboard aloud with on-device speech synthesis.
• Manage speech models, microphone settings, and playback in one desktop app.

Download a model once, then run inference locally. Model downloads need an internet connection. Desktop packages target Windows, macOS, and Linux, including a single-file Flatpak bundle; permissions and text insertion vary by platform. Flatpak updates are handled by Flatpak or by installing a newer release bundle. Flatpak cannot type into other apps, and desktop-wide shortcuts depend on the host session and may be unavailable. Other supported packages use electron-builder update manifests. CI artifacts are currently unsigned and development builds do not contact the update feed.

Speech-to-text includes NVIDIA Nemotron ASR Streaming, an English cache-aware streaming model with a 560 ms latency/accuracy profile. It runs through sherpa-onnx on the CPU after its verified model archive is downloaded; the model remains subject to the NVIDIA Open Model License.
