An AI That Actually Knows You

Whissle adapts to your writing style, remembers your context, and helps you stay on top of life — not just work.

Contextual Writing

Whissle sees what app you're in and adapts. In Mail, it drafts replies in your voice. In Notes, it expands your thoughts. In Slack, it matches the tone of the conversation.

Live Assist in Meetings

During a Google Meet, FaceTime, or any call, Whissle monitors your audio and system audio in real-time. Based on your goals, it gives you live tips, talking points, and context from your emails, notes, and past conversations.

Conversation Memory

Whissle remembers your past conversations. Ask a follow-up hours later and it picks up right where you left off — no re-explaining.

Proactive Triggers

Meeting in 5 minutes? Whissle sends a notification with the agenda. It watches your context and acts before you even think to ask.

Smart Output Routing

Answers go where they belong — pasted into your editor, saved to Notes, sent as a notification, or drafted as an email. Never in the way.

Lifestyle Aware

Whissle knows your schedule, your weather, your news preferences. It keeps you informed throughout the day without you having to ask.

Everything at a Glance

Your email, news, and notes — unified in one place.

Gmail Popup

Intelligence at Every Layer

Not all intelligence comes from the LLM. Whissle's on-device speech recognizer extracts rich metadata — intent, emotion, entities — before anything leaves your machine. For the thinking layer, connect a cloud AI provider for the best results, or go fully local.

On-Device Speech Intelligence

Whissle's advanced ASR extracts entity tags, intent, emotion, age, and gender directly from your voice — before any LLM is involved. Real intelligence starts at the mic.

Local Voice Processing

Your voice never leaves your Mac. All speech recognition and metadata extraction happens entirely on-device. Zero audio sent to the cloud.

Cloud AI (Preferred)

Add your Gemini API key from Google AI Studio for the best experience. OpenAI & Claude support coming soon. Cloud AI delivers the richest, most capable responses.

Local LLM Option

Want total privacy? Use any local LLM model of your choice via Docker. Results may vary compared to cloud providers, but your data stays 100% on-device.
