QuietHint®

Product Introduction

1. Definition: QuietHint® is a native macOS application that functions as a private, on-device AI meeting assistant. It is a real-time speech-to-text transcription and contextual suggestion engine designed for Apple silicon Macs.
2. Core Value Proposition: It exists to provide discreet, real-time conversational support during video calls without compromising privacy. Its core value is enabling users to formulate better responses instantly by processing audio locally and generating AI-powered hints, all while ensuring no audio data is uploaded to the cloud during the conversation.

Main Features

1. On-Device Speech Transcription: QuietHint uses a local speech recognition model downloaded to the user's Mac (macOS 13.2+). It processes two discrete audio channels in real-time: the user's microphone input and the system's audio output (the call audio). This ensures all speech-to-text conversion happens locally, with zero audio upload during the call.
2. Dual-Channel Speaker Labeling: The app algorithmically separates and tags transcribed text as [You] or [Them]. This creates a clean, script-like transcript by distinguishing between the local user's speech and the remote participants' speech captured from the system audio, which is critical for accurate context analysis.
3. Contextual Hint Generation: When a question is detected (in Auto mode) or when manually triggered (⌘↩), the app sends only the recent transcript text—and optionally a screenshot if "Screen" mode is enabled—to Anthropic's API using the user's own API key. It returns a concise, actionable reply suggestion structured as a primary sentence followed by 2-3 supporting bullet points.
4. Non-Intrusive Overlay Interface: The app runs in a floating, always-on-top window that does not take keyboard focus. It provides a live transcript, hint display, and toggle controls for "Auto" hinting and "Screen" context capture, designed to be glanced at without disrupting the primary call window.

Problems Solved

1. Pain Point: The cognitive load and pressure of formulating coherent, strategic responses in real-time during important calls (sales, support, interviews).
2. Pain Point: Privacy concerns associated with cloud-based meeting assistants that record, transcribe, and analyze conversations on remote servers.
3. Pain Point: The inefficiency and post-meeting context loss of relying on manual notes or post-call summaries instead of real-time assistance.
4. Target Audience: Professionals in client-facing roles (Sales Executives, Account Managers, Customer Support Agents), remote team leaders, individuals practicing for interviews, and anyone who frequently participates in high-stakes video conferences on macOS.
5. Use Cases: Sales Negotiations: Crafting counter-arguments to pricing objections. Technical Support: Diagnosing issues based on user descriptions and screen shares. Interview Practice: Structuring responses to behavioral questions. Team Meetings: Clarifying action items and ownership in real-time. Cross-functional syncs: Quickly recalling technical terms or project details.

Unique Advantages

1. Differentiation vs. Cloud Assistants: Unlike bots that join the call (e.g., Otter.ai, Fireflies.ai) or browser extensions, QuietHint is a passive listener on the local machine. It requires no installation on the call platform, leaves no trace in the meeting, and competitors cannot detect its use.
2. Differentiation vs. Manual Methods: Provides immediate, AI-augmented prompting during the live conversation, unlike note-taking apps or post-meeting summary tools that offer retrospective analysis.
3. Key Innovation - Local-First Audio Processing: The fundamental architecture of processing two separate audio streams (mic and system output) locally to create a labeled transcript is a unique technical approach for consumer-grade meeting software. This enables privacy and speaker differentiation without cloud dependency.
4. Business Model Flexibility: Offers a unique "Bring Your Own Key" (BYOK) model for the free and paid tiers, letting users manage their own AI costs and data relationship with Anthropic, alongside traditional subscription and lifetime licence options.

Frequently Asked Questions (FAQ)

1. Does QuietHint work with Microsoft Teams and Zoom? Yes, QuietHint is call-app agnostic. It works with any application that outputs audio to your Mac's system sound, including Zoom, Microsoft Teams, Google Meet, Slack, Discord, Webex, and even FaceTime, as it captures audio at the operating system level.
2. Is QuietHint legal to use in meetings? QuietHint does not determine legality. Users are responsible for complying with local laws regarding recording/transcribing conversations and the specific rules of their organization, meeting platform, or the other participants. It is advised to inform participants where required by law or contractual agreement.
3. What are the system requirements for QuietHint? It requires a Mac with Apple silicon (M-series chip) running macOS 13.2 (Ventura) or later. It needs permissions for microphone and screen/audio recording to capture the call's audio.
4. What happens to my data when using QuietHint? Audio is never uploaded or saved to disk; transcription occurs locally. When a hint is generated, only the recent text transcript (and a temporary screenshot if enabled) is sent to Anthropic's API using your API key. The vendor, QuietHint, states they never see your audio, transcripts, or API key.
5. What is the difference between the Free and Pro plans? The Free plan includes on-device transcription and speaker labeling but limits AI hint generation to 10 total uses. The Pro plan offers unlimited hints, includes the upcoming "Meeting Notes" feature, and is valid on all Macs you own. Both plans require your own Anthropic API key and pay-as-you-go usage costs with Anthropic.
