How to Build an AI Notetaker Like Fireflies.ai (in Days, Not Months)

You don’t need VC money or a 50-person team to build your own Fireflies alternative. Here’s how to go from an idea to a working product in just 4 days.

Why Fireflies.ai Inspired 100 Clones

Fireflies.ai changed the game by automatically joining calls, transcribing conversations, and extracting key insights. It proved that AI notetakers are not just useful - they're essential.

But Fireflies serves a mass audience. That makes it bloated and generic for many niche use cases. You can build something leaner, faster, and more targeted.

Why Build Your Own Fireflies.ai Alternative?

  • Control your stack, UI, and data
  • Tailor it to a specific target group like HR, legal, sales, recruiting, or your own/internal team
  • Avoid per-seat pricing or platform limitations
  • Build with GDPR, HIPAA, or other compliances from day one

What We Will Use To Build Your Notetaker

  • Skribby to handle bots, transcription, and recording, so you don't need to build complex infrastructure
  • OpenAI to transform raw transcripts into valuable summaries and action items
  • Lovable / v0 / Bolt to power your frontend without React complexity
  • Supabase to manage backend, auth, and data storage in one platform
  • (Optional) Stripe to monetize your custom-built notetaker

Now: let’s get started!

4-Day Build Plan

Day 1: Meeting Bot + Storage

await fetch('https://platform.skribby.io/v1/meeting/join', {
  method: 'POST',
  headers: {
    Authorization: `Bearer YOUR_API_KEY`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    meeting_url: 'https://meet.google.com/opn-yxeq-123',
    service: 'gmeet',
    bot_name: 'Skribby',
    meeting_id: '0193225a-35fb-72f3-a21e-3415c8la8db8',
    webhook_url: 'https://your-api.com/webhook/transcript-complete',
  }),
});
  • Set up a Webhook and store the transcript in Supabase:
// Your custom API endpoint listening for webhooks
app.post('/webhook/transcript-complete', async (req, res) => {
  const { meetingId, transcriptUrl } = req.body;
  const transcript = await fetchTranscriptFromUrl(transcriptUrl);

  await supabase.from('transcripts').insert({
    meeting_id: meetingId,
    content: transcript,
    created_at: new Date()
  });

  res.status(200).send('Stored');
});

It’s that simple!

Day 2: Add Summarization

  • Create an account at OpenAI and get an authentication token
  • Get OpenAI’s SDK
  • Use any model (eg. in this case gpt-5) to summarize the transcript:
async function generateSummary(transcriptText) {
  const response = await openai.createCompletion({
    model: "gpt-4o-mini",
    prompt: `Summarize this meeting transcript:\\n\\n${transcriptText}`,
    max_tokens: 1000
  });
  return response.choices[0].message.content;
}

Save these summaries in your DB, etc. You’re good to go!

Day 3: Build the Frontend

  • Use Bolt or v0 to build the UI
  • Create a meeting history/overview dashboard, transcript viewer, summary page, …
  • Add Supabase Auth for user login/registration

Day 4: Launch

  • Build a marketing site using Lovable
  • Deploy your SaaS and marketing website for free to services like Vercel or Netlify
  • Share on Product Hunt, Reddit, LinkedIn, …

Use Cases: Go Vertical, Not Broad

  • Recruiting - Interview meeting transcripts, ATS summaries
  • Sales - Meeting notes + action items to CRM
  • Legal - Timestamped call meeting records for compliance
  • Healthcare - Transcripts & summary of appointment meetings
  • Research - Auto-summarized user interviews

These are underserved by horizontal tools like Fireflies.

Why Skribby Is Your Unfair Advantage

Without Skribby, you'd need to build your own:

  • Zoom/Meet/Teams meeting bot infrastructure
  • Speech-to-text (transcription) layer

With Skribby, you simply:

  • Join any meeting
  • Get transcript + audio
  • Handle everything via webhooks (and also possibly real-time!)
