⏰ Relax: your credits come back on their own at midnight (Brasília time). The free plan limit is daily — tomorrow you transcribe again, no action needed.

Want more than that? 3 paths — 2 of them free

From fastest to most complete. Any one works; you can combine all three.

Path 1 — Refer a friend FREE · 2 MIN

  1. Open ZapVox and click the “Invite and earn 7 Pro days” section.
  2. Copy your link and send it to a friend (on WhatsApp, naturally).
  3. When they install and sign up through your link, you earn 7 days of Pro — and they get 7 extra trial days.
Each friend = 7 Pro days for you both, up to 60 days accumulated per account. Full rules →

Path 2 — Bring your own AI key (BYOK) FREE · 5 MIN

You create a free key at Groq (the AI provider behind transcription) and paste it into ZapVox. Transcription then runs on your key, straight from your browser — without ZapVox's daily limit. Four steps, and no card required.

1. Create the Groq account

Open console.groq.com/keys. You can sign in with Google, GitHub or email.

2. Click “Create API Key”

Once signed in you land on the API Keys page. The button sits on the right.

3. Name it and confirm

Groq's Create API Key dialog, with name, expiration and human verification
  1. Display Name: anything you'll recognise later — “ZapVox”, say.
  2. Expiration: “No expiration” is fine. Pick a date and the key stops working on it.
  3. Tick “Verify you are human” and confirm.
  4. Copy the key right away. It starts with gsk_ and Groq shows the full value only once — after that you only see its last characters.

4. Paste it into ZapVox

In the ZapVox panel: 🎙️ Transcription → 🔑 API tab → Configure keys. Paste it in the Groq field.

How much does the free key give you?

These are the limits Groq's rate-limit page published on 31 Aug 2026 for the whisper-large-v3-turbo transcription model on the free plan:

LimitGroq free planRoughly
Audio per hour7,200 seconds2 hours of audio
Audio per day28,800 seconds8 hours of audio
Requests per minute2020 audios in a row
Requests per day2,0002,000 audios
Full transparency: we have no commercial ties with Groq — we earn no commission when you create an account there. Their free tier has its own limits, and their policy, prices and availability can change at any time, outside our control. OpenAI keys are also accepted (that one is billed by OpenAI).
🔒 The key is stored encrypted in your browser and goes straight from your browser to the provider — it never passes through our servers. That is not a substitute for antivirus: on a shared computer, remove the key when you're done.

Path 3 — ZapVox Pro R$ 29.90/MO

  1. Much higher transcription limits, auto-translation, summaries, sentiment analysis, daily digest, glossary and audio search.
  2. No watermark on copies and sends.
  3. First month at 75% off on the monthly plans, automatic, no code needed (discount applies to the 1st charge only).
