Input

Zero-typing voice dictation with local transcription and AI polish on macOS

59/100MonitorFreeFree

If you live on macOS and want hands-free dictation without surrendering your audio, Input0 is hard to beat. The need to bring your own LLM API key adds friction, but the local transcription speed and privacy payoff are real. We'd pick it over cloud dictation for any sensitive or high-volume writing.

Skip it if

Skip Input0 if you're on Windows or Linux, if you want a cloud-based dictation service that requires no setup, or if you're not willing to manage your own LLM API key for text polishing.

The 30-second take
Biggest gripe

You must supply your own LLM API key for text polishing, which means you'll incur token costs from your provider (e.g., OpenAI, Anthropic) based on your usage.

Price reality

Input0 is free to download and use, with no subscription or paywall. The only cost is your own LLM API usage for the polishing step, which is typically a few cents per month for light daily use. Compared to cloud dictation services like Otter.ai or Rev, which charge $10-20/month and send your audio to the cloud, Input0 is cheaper and more private. For heavy dictators, the API cost might approach a paid tier, but for most individuals, it's minimal.

In short

Input — Zero-typing voice dictation with local transcription and AI polish on macOS. Best for Developers dictating code or documentation hands-free, Writers and content creators seeking faster input, Power users reducing typing and RSI risk. Free to use.

About Input

FreeBeginner-friendlyNo APIDesktop

Input0 replaces typing with your voice, letting you press and hold Option+Space anywhere in macOS, speak, and release to have your words transcribed and polished before being auto-pasted into any app. Built in Rust with Metal GPU acceleration, it transcribes entirely on-device — guaranteeing your audio never leaves your Mac — then sends only the text to your own LLM API for refinement. The polishing step strips filler words, fixes grammar, and corrects 40+ technical terms by pronunciation, so "rui en te" becomes "React" without extra editing. It even maintains a 10-message context window to keep your phrasing consistent across the conversation. All of this happens with a subtle glass overlay that respects your focus, meaning no window switching or friction in your flow. Language support is a highlight: 6 AI engines with 12 models cover 99+ languages, from Whisper for broad multilingual use to specialized engines like SenseVoice for CJK, Paraformer for Chinese/Cantonese, Moonshine for faster English, and FireRedASR with a low ~2% CER. The tool automatically recommends the best model for your language, and you can download only the models you need. A custom vocabulary feature handles names, brands, and jargon, while the AI learns from your corrections through LLM validation. Input0 is a privacy-first alternative to cloud dictation services. No accounts, no clouds, no tracking — your voice data stays local, and you control the text-processing pipeline via your own LLM API key. That setup overhead is the main trade-off: this is a tool for developers, writers, and privacy-minded power users who want speed and sovereignty, not a zero-config consumer app. If you're comfortable managing an API key, it's one of the fastest ways to get thoughts into text on macOS.

Behind the Verdict

Input0 nails the core promise: zero-typing voice input with local-first privacy. On an Apple Silicon Mac, holding Option+Space and speaking feels nearly telepathic, with on-device transcription via Metal GPU ensuring your voice data stays put. The polish step—which leverages your own LLM API—removes filler, fixes grammar, and even corrects 40+ technical terms by pronunciation. That's a genuinely useful layer for developers who dictate code and need "rui en te" to become "React" without a second thought. The 10-message context window is a thoughtful touch: it keeps your phrasing consistent across a conversation, so your writing doesn't oscillate between formal and casual. And the custom vocabulary plus auto-learning via LLM validation means the tool adapts to your jargon over time—a feature set that typically only appears in enterprise tools. But Input0 is not for everyone. It's macOS-only, and it requires you to supply your own LLM API key for the polishing step. That's a dealbreaker for casual users who just want to dictate a quick text message, and it means you're paying per token if you exceed free tiers from providers. There's no team collaboration, no sharing, no real-time editing—it's a personal productivity tool, not a team platform. Where it shines: developers, writers, and power users who value privacy and speed. If you're on macOS and tired of cloud dictation that hoovers up your audio, Input0 is a compelling, honest alternative. If you need cross-platform support or a zero-config app, look elsewhere.

Hidden costs & gotchas

What the public pricing page doesn't put in bold. Captured from pricing-page footnotes, contract terms, and recurring complaints.

  • You must supply your own LLM API key for text polishing, which means you'll incur token costs from your provider (e.g., OpenAI, Anthropic) based on your usage.
  • Input0 only supports Apple Silicon Macs (M1 or later), so if you're on an Intel Mac, you'll need a hardware upgrade first.

Where the pricing makes sense

The company stage and team size where Input's pricing actually pencils out — and where peers do it cheaper.

Input0 is free to download and use, with no subscription or paywall. The only cost is your own LLM API usage for the polishing step, which is typically a few cents per month for light daily use. Compared to cloud dictation services like Otter.ai or Rev, which charge $10-20/month and send your audio to the cloud, Input0 is cheaper and more private. For heavy dictators, the API cost might approach a paid tier, but for most individuals, it's minimal.

Setup time & first value

How long it actually takes to get something useful out of Input — broken out by persona, not the marketing-page minute.

For a developer comfortable with API keys: ~5 minutes to install, configure your LLM API key, and test the hotkey. For a non-technical user: ~15 minutes, as you'll need to create an API key and understand the setup. Once configured, it's ready to use immediately.

Migrating in
  • From cloud dictation (e.g., Otter, Rev): Install Input0, set your LLM API key, and start dictating locally. You'll lose cloud sync but gain privacy and lower latency.
