PromptPaste App

Windows developers who use AI coding tools — Claude Code, Codex CLI, Cursor, Copilot Chat — and want to write longer, clearer prompts without typing them out. Secondary audiences include developers with RSI or typing fatigue, developers working in privacy-sensitive or air-gapped environments where cloud transcription isn't allowed, and anyone who prefers speaking over typing for ideation and "thinking out loud" while coding.

PromptPaste is the only voice-to-text tool built specifically for AI coding workflows on Windows. Unlike generic dictation apps, it's designed around the push-to-talk + paste-into-terminal loop that developers using Claude Code, Codex CLI, and Cursor actually rely on. Transcription runs fully on-device via local Whisper — no cloud, no API keys, no audio ever leaves your machine. It's also Windows-native, while most modern voice tools in this space target macOS first.

Local and private by default — Wispr Flow and most competitors send audio to the cloud. PromptPaste runs Whisper on-device, so it works offline, in air-gapped environments, and with zero data leaving your machine. Built for developers, not general dictation — optimized for terminals, code editors, and AI chat apps rather than Word documents. Windows-first — Superwhisper is macOS-only, Talon is power-user-heavy. PromptPaste is a clean Windows desktop app that "just works" out of the box. No subscription required for the core feature — local dictation is free forever. You only pay if you want live mode, target lock, and premium support. Image paste into AI apps — drop clipboard screenshots directly into Claude, ChatGPT, and other AI tools that accept image input.

PromptPaste started because AI coding tools reward longer, more detailed prompts — but typing 200-word prompts into a terminal dozens of times a day is slow and hard on your hands. Existing voice tools either sent everything to the cloud (a non-starter for privacy-conscious developers and restricted work environments), were macOS-only, or weren't built for the terminal/editor workflow at all. PromptPaste was built as a Windows-native, local-first voice layer for the exact moment a developer wants to say "hey, refactor this function so that..." and have it land in their editor instantly.
