Sales Call Assistant

A sales call assistant that helps you during the call, not after it — invisible on Zoom, Teams, and Meet, and local-first by default.

What a sales call assistant does

On a live call you're doing five things at once: listening, qualifying, handling objections, taking notes, and watching the clock. A sales call assistant takes the cognitive load off the parts a machine is good at — transcribing, recalling, and surfacing the right line — so you can spend your attention on the human across the table.

Cloak does this from an overlay only you can see. It listens to both sides of the conversation through system audio, keeps a live transcript, and — the moment a hard question or objection lands — drafts exactly what to say, grounded in your product notes and the account context you loaded.

Built for client trust

Sales calls carry sensitive commercial information, so where that data goes matters. Cloak is local-first: audio capture, the transcript buffer, and conversation history live on your machine. Network calls happen only when you send a prompt to the AI provider you chose — and with bring-your-own-key, that's your own OpenAI, Anthropic, Gemini, or Groq account, not ours.

The overlay is excluded from screen capture at the OS level, so if you're sharing your screen to walk through a deck, the assistant never appears in the recording or the share.

Key features for sales teams

  • Real-time objection handling — the moment "it's too expensive" or "we already use X" lands, Cloak drafts a response in your voice.
  • Live transcript — both sides of the call, captured from system audio, scrollable as you go.
  • Account-aware answers — load the prospect's company and Cloak builds a dossier (stack, recent news, priorities) and folds it into replies.
  • Talk-track modes — switch between a direct answer, exact phrasing to say, or a quick brainstorm of angles.
  • Post-call notes — structured summary, action items with owners, and next steps the moment you hang up.
  • Your keys, your model — BYOK free forever, or a managed plan with quota.
  • Invisible by design — never shows on Zoom, Teams, or Meet shares.

Who it's for

Account executives running discovery and demos, SDRs on qualification calls, founders doing their own sales, and customer-success teams handling renewals and escalations. If you've ever frozen on a pricing question or forgotten to capture a next step, a sales call assistant earns its place.

FAQ

Can the prospect see or detect it?

No. The overlay is content-protected and excluded from screen sharing and recording. It listens to audio locally; nothing is injected into the meeting.

Where do my call transcripts go?

They stay on your Mac. Cloak only sends the text you prompt against to your chosen model provider. There's no Cloak-side recording of your calls.

Can I tailor it to my product and pitch?

Yes — load product notes, pricing, and competitor positioning as context, and Cloak grounds every answer in them instead of generic boilerplate.

    One-line fix (if blocked)

    Open Terminal (press ⌘ Space, type "Terminal"), paste this command and hit Return:

    Terminal — zsh
