About

Piper is the AI operating system for preconstruction, built for general contractors' pursuit and estimating teams. Piper connects drawings, specifications, addenda, quotes, estimates and company knowledge so teams can generate scopes, level bids and review risk — with every finding linked back to the drawing, spec clause or addendum it came from. Scope Generation: turn drawings, specifications, addenda and company standards into source-backed trade scopes, so you know exactly what you are asking each trade to carry. Bid Leveling: compare subcontractor bids against the intended scope, so the low number does not hide an expensive gap. Final Bid Review: review the estimate against the project behind it, and focus senior attention on what still deserves judgment. Survey: turn your company's experience into a repeatable survey that captures what the team learns on every project. Piper is not a takeoff or estimating calculator, and it does not replace estimator judgment.

About

Piper is a fast, local neural text-to-speech (TTS) system optimized for devices like the Raspberry Pi 4, designed to deliver high-quality speech synthesis without relying on cloud services. It utilizes neural network models trained with VITS and exported to ONNX Runtime, enabling efficient and natural-sounding speech generation. Piper supports a wide range of languages, including English (US and UK), Spanish (Spain and Mexico), French, German, and many others, with voices available for download. Users can run Piper via the command line or integrate it into Python applications using the piper-tts package. The system allows for real-time audio streaming, JSON input for batch processing, and supports multi-speaker models. Piper relies on espeak-ng for phoneme generation, converting text into phonemes before synthesizing speech. It is employed in various projects such as Home Assistant, Rhasspy 3, NVDA, and others.
