Show HN: Dictata – Local Whisper Dictation with LLM Cleanup

Dictata demonstrates a practical end-to-end local inference pipeline combining Whisper speech recognition with LLM-based cleanup and correction. By running both components locally, users achieve private dictation without sending audio to cloud services, addressing privacy and latency concerns for sensitive applications like medical dictation or confidential note-taking.

The tool showcases how composing multiple specialized local models (Whisper for speech, an LLM for grammar/coherence correction) creates capabilities rivaling cloud services while maintaining data privacy. This pattern—using smaller, focused models in sequence—is increasingly common in local deployment as practitioners discover that orchestrating multiple specialized tools often outperforms larger monolithic approaches.

For developers building privacy-preserving applications, Dictata provides a reference implementation and validates the viability of local speech processing. As open-source Whisper continues improving and lighter LLMs become available, similar multi-model pipelines will likely proliferate in applications from transcription to document processing.
