Built for Developers Who Live in Their Tools
No awkward typing pauses when pairing with AI coding agents or documenting pull requests.
Context-Aware File Tagging
Tag files in Cursor, Windsurf, Claude Code, and Copilot hands-free. Speak 'tag file src/auth.ts' and Murmur formats '@src/auth.ts' right into your prompt.
Instant Code Casing
Dictate camelCase, snake_case, PascalCase, SCREAMING_SNAKE_CASE, kebab-case, or `backticks` without touching your shift key.
Voice Snippets & Templates
Trigger PR checklists, environment setup guides, API specs, bug reports, and daily stand-ups with simple voice shortcuts.
1-Click Codebase Symbol Importer
Scan your package.json, Cargo.toml, or workspace files to instantly import project-specific types, functions, and module names into your local dictionary.
100% On-Device & Zero Cloud Leaks
Never stream company proprietary code or secret prompt context to 3rd-party servers. Murmur runs 100% offline with local whisper.cpp.
Sub-200ms DirectML & Metal Speed
Zero network round trips. Hardware-accelerated local inference delivers transcription directly to your cursor faster than cloud round-trips.
Works Seamlessly Across Your Developer Stack
Murmur injects text directly into the focused window via native OS events. No browser extensions or plugins required.
Murmur vs. Wispr Flow for Developers
Why privacy-conscious engineering teams choose on-device Murmur over cloud subscriptions.
