YapYap
A fast, private desktop client for WhatsApp Web, for Linux, Windows and
macOS, with a built-in AI assistant that helps you write: reply ideas and
rewrites, right in the message box, with a private model on your computer
or the AI service you choose.
YapYap is unofficial. It is not affiliated with, endorsed by, or
sponsored by WhatsApp or Meta. "WhatsApp" is a trademark of its owner.
YapYap loads the official WhatsApp Web in a hardened desktop shell. It does
not reimplement WhatsApp's protocol and does not automate your account.
Install
Download YapYap for Linux, Windows or macOS from the
releases page, or add the
apt, dnf or pacman repository at packages.guita.org, as the
install guide explains, then
get started in six steps. Each
release's changes are in CHANGELOG.md.
Status
YapYap is young and not yet at 1.0. Follow what comes next on the
project board and in
docs/progress.md.
Highlights
- A built-in AI assistant in the message box: it suggests short replies
when someone writes to you, and rewrites what you type to polish,
shorten, elaborate, soften or formalize it. Use a private model that
runs on your computer, a model server you already run, or Claude or
OpenAI with your own key. It works only in the chats you choose, and
never sends a message on its own.
- An opt-in MCP server: AI agents on your computer can read chats, write
drafts and, only if you allow it, send messages, as far as the token you
give each one allows
- Multiple accounts with fully isolated sessions
- Native notifications, tray or menu bar with unread counts, and do-not-disturb
- Recovery tools that fix a stuck session without logging you out
- No telemetry

Support YapYap
YapYap is free, with no ads and no telemetry. If it is useful to you, you can
sponsor its development.
Sponsorships pay for what building YapYap costs:
- Development tools: a Claude subscription for AI-assisted development.
A higher plan means fewer pauses when the usage limit runs out.
- Code signing: a Windows certificate, so YapYap installs there without
a security warning, as it already does on macOS.
Supporters
YapYap's development is supported by Ensita, a
nonprofit that builds free, open-source apps that keep your data yours, and
mentors new developers.
