How HAINT Works

HAINT is your invisible AI assistant for high-stakes conversations. Here's how it works step-by-step.

1. Install HAINT

Download HAINT for Windows and complete the setup wizard.

2. Launch & Sign In

Launch HAINT from the desktop shortcut or Windows Start menu.
Right-click the tray icon → Settings → Account tab → "Sign in via Browser".
After signing in, hover over the tray icon or check Settings → Account to view your remaining balance.

3. Connect Safe Headphones

HAINT automatically pairs safe output (headphones/headsets) with your microphone at startup.
Private devices only — output to laptop speakers is disabled by design to ensure privacy.
Others on the call will never hear your hints.

4. Use During Calls

Join your call (Zoom, Teams, Google Meet, Telegram, WhatsApp, etc.).

  • Shift: Start / restart audio capture (microphone + system audio)
  • Ctrl: Submit request to AI (while recording) OR pause/resume voice narration (while speaking)
  • Esc: End session (soft reset) and add optional session memo
  • Alt: Toggle subtitle window visibility | Home: Center subtitle window

3 Real-Time Operating Modes

Select your mode under Settings → General → Operation Mode:

  • AI Hints: Real-time contextual suggestions for interviews, presentations, and negotiations. Customize detail level (Keywords / More Informative) and separator pauses.
  • Translate: Concise, real-time translation summaries. Enable auto-start capture after Ctrl translation (available when Audio narration is off).
  • Steno: Fact extractor for continuous speech. Extract names, dates, numbers, and decisions into a sliding audio window (Short 45s / Normal 90s / Long 150s). Voice playback (TTS) is disabled; text responses are saved automatically.

Audio-Native AI — Hears Tone & Context

HAINT captures both incoming system audio (WASAPI Loopback) and your microphone input in real-time.

  • Full context preserved: Tone, pace, emphasis, hesitation — captured seamlessly
  • Faster response: Real-time streaming via secure WebSocket proxy
  • Better accuracy: Full conversation context without loss of detail

Full Call Recording

Continuous local audio archiving independent of short Shift/Ctrl capture bursts:

  • Dual-track archive: Opt-in continuous recording of microphone and/or incoming system audio
  • Auto-start on call: Automatically begin recording when known call apps (Telegram, WhatsApp, Zoom, Teams) become active
  • Contact memo: Esc memo dialog automatically pre-fills messenger contact names for easy retrieval

AI Secretary (Telegram)

Async personal AI assistant outside of live calls:

  • Edit personal context document directly in Settings → Secretary tab
  • Link Telegram account via 6-digit code flow
  • Chat asynchronously with your bot in Telegram grounded in your personal context

Attach Screenshots as Visual Context

Need help with content on screen?

  • Hold Right Alt: Capture screenshot (replace). If not recording, HAINT auto-starts capture first.
  • Right Alt + Right Ctrl: Append screenshot (up to 4 frames).
  • Monitor selection: Select target monitor in Settings → General. Images are optimized for fast transmission.

Load Your Reference Context

In AI Hints mode, open Edit User Context… to paste text or load a .txt / .md file (up to 20 KB). HAINT prioritizes your price list, resume, contract, or notes during responses.

Read or Listen

  • Voice (Narration): Local Windows WinRT TTS spoken privately in your headphones. Select Male/Female voice gender and accelerate playback speed (1.1x–2.5x).
  • Floating Subtitles (Text Display): Customizable text overlay with font size (13–21), background transparency (0–100%), and outline for readability.

Saved Sessions & Local History

Browse saved sessions in Settings → Saved Sessions:

  • Local storage: Saved under %LOCALAPPDATA%/HAINT/History/ (WAV audio, TXT responses, PNG screenshots)
  • Interactive HTML reports: View chat-style reports for past calls
  • Session memos: Add notes and contact labels to organize call history

Privacy & Security

  • Real-time audio processing over TLS proxy WebSocket
  • Private audio output enforced (headphones only)
  • Optional session history and continuous Full Call Recordings are stored 100% locally on your computer

See our Privacy Policy for details.

System Requirements

  • RAM: 4GB minimum, 8GB recommended
  • Audio: Safe headphones/headset and microphone required

Frequently Asked Questions
