Features
What Zap does in WhatsApp
One account, up to two WhatsApp numbers. Same workflow for personal and business chats — transcripts, summaries, translation, and AI inside the conversations you already use.
Transcription
100+ languages, auto-detected
Powered by Groq's hosted Whisper. Speaker-aware, punctuated, accurate. The audio language is detected automatically — no settings to fiddle with.
Translation
Translate any transcript on demand
50+ target languages with one command. Pick a default per chat so the right translation appears next to every transcript without you asking.
AI Agent
Ask Zap from inside the chat
Use /zap for AI answers, /balance to check credit, /status for pairing, /help for the command list. No separate app to open.
Wallet
Prepaid wallet that never expires
Start with $100 free credit this Testing Season, then top up by any amount — $5, $10, $25, whenever. Credits never expire. Account pauses gracefully at zero balance — no surprise charges.
What you get
Built for the WhatsApp workday
Nine capabilities that work on day one, inside the WhatsApp you already use.
Voice transcription, 100+ languages
Audio is auto-detected and transcribed. Portuguese (BR & PT), English, Spanish, French, Italian, German, Mandarin, Japanese, Korean, Arabic, Hindi, and 90+ more.
Smart summaries
For audios over 2 minutes, Zap returns a clean bullet summary with the key points so you can skip the replay.
Action item extraction
AI pulls structured to-dos out of voice messages — “Send sales report”, “Schedule meeting on 10/10” — right in the chat.
Translation, 50+ languages
Translate any transcript on demand. Pick a default language for each contact, or trigger translation when a chat needs it.
WhatsApp group support
Your own voice notes get transcribed in groups too — not just 1:1 chats. Most competitors can’t do this.
Ask Zap inside WhatsApp
Send /zap followed by any question for a paid AI answer. Check balance, status, top-up — all inside WhatsApp.
Prepaid wallet that never expires
Top up by $5, $10, $25 — whenever. Unused credit never disappears. Account pauses cleanly at zero.
Two WhatsApp numbers
Run personal + business WhatsApp from one Zap account. Each number gets its own settings and language preferences.
Privacy by default
Audio is processed in real time and discarded after transcription. We never store raw voice notes on our servers.
Transparency
What you don’t get (and why)
- No transcription of others’ audios in groups. WhatsApp privacy rules — only your own outgoing audios are transcribed inside groups.
- No voice cloning or speaker identification. We transcribe what was said, not who said it. Stays on the right side of privacy law.
- No data resale or training on your audio. Your transcripts are yours. We don’t sell them and don’t feed them to public models.
How it works
Connect in 4 steps
One web flow. Four steps. Your transcripts start landing in WhatsApp the moment your number is paired.
- 1 Create your account — name, email, language, password.
- 2 Authorize WhatsApp access — confirm we may read voice notes sent to your number for transcription.
- 3 Link WhatsApp with the 8-character code shown in Zap: WhatsApp > Settings > Linked Devices > Link a Device > Link with phone number instead.
- 4 Send any voice note. The transcript, summary, and tasks appear in the same chat.

Pricing

$0.12 per minute, billed as $0.02 for every started 10 seconds — no minimum, no monthly fee
Cost per note
What a single voice note costs
Every audio rounds up to the next 10 seconds. Common lengths:
| Voice-note length | You pay | $100 free credit covers |
|---|---|---|
| 0:10 | $0.02 | up to 5,000 of these |
| 0:30 | $0.06 | up to 1,600 of these |
| 1:00 | $0.12 | up to 800 of these |
| 2:00 | $0.24 | up to 400 of these |
| 5:00 | $0.60 | up to 160 of these |
| 10:00 | $1.20 | up to 80 of these |
Rough rule of thumb: your $100 Testing Season credit covers about 13 hours of audio or more than 400 two-minute notes.
Top-up bonus
The more you load, the more you get
No packages, no monthly tiers — just a bigger bonus when you add more credit at once. Bonus lands the moment your top-up clears.
| You add | Bonus credit | You get | Total minutes |
|---|---|---|---|
| $5 | — | $5 | 41 min |
| $10 | — | $10 | 83 min |
| $25 | +$3 bonus | $28 | 233 min |
| $50 | +$10 bonus | $60 | 500 min |
| $100 | +$25 bonus | $125 | 1,041 min |
All credit lives in your prepaid wallet and never expires. Top up in any amount — the table shows where the bonus tiers kick in.

FAQ
Fast answers, zero fluff
Everything you need to know before sending your first voice note.
How fast is a transcript?
Most voice notes return a transcript in under 3 seconds. Long audios (10+ minutes) take a bit longer but rarely more than 15 seconds. You'll see it land in the same chat.
Do unused credits expire?
No — never. Once you top up, your wallet balance stays until you spend it. No expiry, no monthly resets, no "use it or lose it" pressure.
Will Zap transcribe other people's voice notes in groups?
No — only your own audios in groups, by design. WhatsApp's privacy rules don't allow third-party transcription of others' messages in shared chats. In 1:1 chats where you've been pair-authorized, both sides' audios are transcribed.
What languages do you support?
100+ for transcription (auto-detected), 50+ for translation. The site itself is in English, Portuguese, and Spanish — pick your flag in the header.
How do I top up my wallet?
Any amount via PayPal — $5, $10, $25, $50, $100, or pick your own. We support Apple Pay and card too. The minimum top-up is $1 (which buys about 8 minutes at $0.12/min). Add $25+ for a bonus tier — see the pricing section.
Can I get a refund on unused credit?
Yes — email info@zap.bz within 30 days of top-up and we'll refund whatever's left. After 30 days credit stays in the wallet (it never expires) but is no longer refundable.
Is my audio stored anywhere?
No. Audio is processed in real time and deleted immediately after the transcript is generated. We never store recordings. Only the resulting text + metadata (chat, timestamp, duration) lives on your account.
What is the $100 Testing Season credit, and how do referrals work?
During our Testing Season, every new account starts with $100 in free credit — no credit card needed. Want to share it? In WhatsApp, type /friend in any chat or group and Zap drops your personal invite link. Each friend who signs up with it gets their own $100, and you earn $10 in credit for every friend who joins.
