Zapkit: WhatsApp Web toolkit

Zapkit is the toolkit WhatsApp Web never had.

It lives inside the page you already use. There is no other app to open, no number to change, no API key to paste, and nothing happens until you click.

━━━━━━━━━━━━━━━━━━━━ AI, with no key to set up

• TRANSCRIBE a voice message in one click. An eight minute audio becomes text you read in twenty seconds, right in the chat. • SEARCH inside what was said. Everything you transcribed becomes searchable, so you can find which voice message mentioned that address or that price. • TRANSLATE incoming and outgoing messages. Both ways, so you can serve someone in a language you do not speak. • REWRITE what you are about to send: fix spelling, make it clearer, more direct, more formal, friendlier, or give it a business tone. Seven presets, and the text lands in the box for you to review. Nothing is sent automatically. • SUMMARIZE a long conversation or a long voice message, and get what was decided and what is still open.

The AI runs on Zapkit's servers. You do not create an account, paste a key or pick a model.

━━━━━━━━━━━━━━━━━━━━ Privacy, on your screen and on your account

• PRIVACY MODE blurs what is on display and reveals only what your mouse is on. Eleven separate controls: contact names, photos, recent messages, the open conversation, the message box, and more. Useful in an office, a cafe, or a screen share. • PIN LOCK hides your chats behind a code. It can lock on its own after idle time, sound an alarm on wrong attempts and refuse new tries for a while. The PIN is stored as a salted hash on your machine and never transmitted. • READ WITHOUT A RECEIPT, view a status without notifying, play a voice message without the sender knowing, and hide your typing and recording indicators. • RESTORE messages that were deleted for everyone, from what had already reached your screen.

━━━━━━━━━━━━━━━━━━━━ The everyday work

• REMINDERS that fire at the time you set, optionally tied to a conversation. They warn by system notification and on screen, and survive the browser restarting. • QUICK REPLIES behind a slash shortcut. Type /quote and space, and the canned answer lands ready to edit. • NOTES about a contact, attached to the chat, visible only to you and never sent. Searchable across every contact. • WAITING FOR A REPLY: the list of chats where the last message is theirs and you have not answered, built on its own from who spoke last. • KEYBOARD SHORTCUTS for the main actions, including locking the session instantly. • A HEADS-UP when someone starts typing in a conversation that is not on your screen. • Pin beyond the native limit, mark as read or unread from the header, start a chat with a number that is not in your contacts, and download a status.

━━━━━━━━━━━━━━━━━━━━ Made to feel like yours

Interface in English, Portuguese and Spanish. Five base themes plus twelve color palettes, eighteen icon styles, and every feature has its own on and off switch. Turn on only what you use.

━━━━━━━━━━━━━━━━━━━━ What leaves your machine, and what does not

Zapkit reads nothing in the background. A message goes to our servers only when you click transcribe, translate, rewrite or summarize, and it is discarded once the answer comes back. Your quick replies, your reminders, your PIN and the transcripts you asked for stay in your browser. Contact notes are kept in your account so they survive a change of computer, with the contact identified by an irreversible hash, never by the number.

━━━━━━━━━━━━━━━━━━━━ Free and Pro

Free is a real plan, not a trial: everything above, with quotas of 3 active reminders, 3 quick replies and the core AI presets. Pro removes the limits and unlocks the rest, monthly or yearly.
