AI Meeting Copilot

Build an AI meeting copilot that gives sales reps and teams live, in-call prompts — objection responses, follow-ups, summaries. Full build guide with AI prompts.

Remote meetings are where deals stall and energy dies. A sales rep on a video call hits an objection and blanks. A team standup drifts into silence and runs ten minutes long. The pattern repeats billions of times a year across Zoom, Teams, and Meet, and the cost is real: lost deals, video-call fatigue, and meetings that should have been emails. The tools that exist solve the wrong half of the problem. Otter, Fireflies, and Zoom's own AI are excellent at telling you what happened after the call — transcripts, summaries, action items. None of them help you in the moment, when the rep needs the right objection response or the facilitator needs a question to break the silence. The live conversation, where outcomes are actually decided, is unassisted. The only "real-time" workaround is alt-tabbing to ChatGPT mid-call, which breaks eye contact and flow.

Built for Solo Founders, Developers.

Suggested stack: Chrome Extension + Electron (optional desktop), Deepgram or AssemblyAI streaming, Claude (live prompts) + fast model for triage, Next.js + Vercel dashboard, Supabase (Postgres + pgvector), Stripe Billing. Weekend scope: about 12 hours.

The Problem

The expensive moment is live, not post-meeting — a fumbled objection or dead-air silence loses the deal in real time, and no popular tool helps there.

The Solution

AI Meeting Copilot runs quietly alongside Zoom, Teams, or Meet and feeds the speaker live, glanceable prompts: the objection rebuttal a rep needs, a follow-up question when a team…

  1. 1. Project Setup

    Build the weekend MVP of "AI Meeting Copilot": a Chrome extension that shows a speaker short, live prompts during a sales call.
    
    Stack: a Chrome extension (TypeScript) that captures the active meeting tab's audio and shows a compact sidebar, a Next.js (App Router) dashboard, Supabase (Postgres with pgvector, Row Level Security, Auth with email magic link), Deepgram for streaming transcription, Claude (Anthropic API) for the prompts. Deploy the dashboard on Vercel.
    
    Tables (Row Level Security on, each user reads only their own rows):
    - playbooks(id, user_id, name)
    - objections(id, playbook_id, moment_type, trigger_text, response, embedding vector(1536))  where moment_type is one of objection, awkward_silence, competitor_mention, question_asked
    - meetings(id, user_id, started_at, ended_at)
    - prompts_shown(id, meeting_id, moment_type, text, helpful)
    - summaries(id, meeting_id, summary, action_items jsonb, engagement jsonb)
    
    Screens: dashboard Playbook and Meeting History, plus the extension sidebar.
    Env vars (names only): NEXT_PUBLIC_SUPABASE_URL, NEXT_PUBLIC_SUPABASE_ANON_KEY, SUPABASE_SERVICE_ROLE_KEY (server only), DEEPGRAM_API_KEY, ANTHROPIC_API_KEY, EMBEDDINGS_API_KEY.
    
    Do not build: billing, plans or tier gating, teams, analytics pages, Zoom or Teams apps, the playbook learning loop, an Electron app.
    Done when: the extension loads unpacked in Chrome, you can sign in on the dashboard, and the five tables exist with pgvector on and Row Level Security on.
  2. 2. Core Feature

    Build the one feature that proves the idea: a live prompt on screen within a second or two of the moment.
    1. Stream the captured tab audio to Deepgram for low-latency transcription.
    2. On each utterance, ask a small fast Claude model to classify the moment as objection, awkward_silence, competitor_mention, question_asked or none.
    3. For an actionable moment, retrieve the best-matching entry from the playbook by vector search, and ask Claude for one short prompt of under 20 words for the speaker's sidebar.
    4. Show the prompt in the sidebar. Log it to prompts_shown, with a thumbs-up that sets helpful.
    5. After the call ends, write a summary, action items and an engagement score (talk-time balance, silence count, question count) to summaries, without blocking the live path.
    Rules: the prompt must appear within about 1 to 2 seconds. Keep the heavy summary work for after the call.
    Empty state: with no playbook entries, show the form to add the first objection and its best response.
    Done when: a test call with a spoken objection shows a matching under-20-word prompt in the sidebar within about two seconds, and the call ends with a saved summary.
  3. 3. Landing Page

    Build a one-page landing site for AI Meeting Copilot, live in-call prompts for sales teams.
    Hero: "Never let a call stall again." Sub: "Live, glanceable prompts for objections, silences and competitor mentions, right in your meeting window." One button: Join the waitlist.
    Sections: the problem (a stalled call and a lost deal), how it works in three steps (connect your meeting tool, get live prompts in a sidebar, review after the call), a mock sidebar with an objection prompt, and an FAQ on recording, privacy and which meeting tools work.
    Waitlist: store the email in a waitlist table in Supabase. No other service.
    Voice: confident, short and respectful of the seller.
    Done when: the page renders on a phone and a submitted email appears in the waitlist table.
  4. 4. Branding Package

    Use a design or image tool for this one. A coding agent cannot draw a logo.
    Brand for AI Meeting Copilot: a wordmark and an icon that suggest a quiet nudge, not an alarm.
    Colors: near-black, white and one calm accent, with an amber used only for a live prompt. Type: one clean sans for the interface.
    Deliverables: wordmark, icon, a sidebar prompt card style, and one launch graphic.
    Done when: each deliverable is saved in one folder and the prompt card reads at 14 px.
