Contakt — send a message without saving the number Start a chat or send a pre-filled message to any phone number on WhatsApp, Telegram, Signal and other messengers — without adding it to your contacts first. See a number on a web page? Click to chat in one tap. Stop cluttering your address book just to message someone once. Everything stays on your device, and your message content is never sent to a server. Features: 📱 Number detection — Automatically finds phone numbers on any web page and underlines them subtly. One click opens your chosen messenger. Validation for 245 countries. 💬 Multiple messengers in one window — Pre-filled message text on WhatsApp, Telegram and Signal; one-tap chat open on the others. 📇 Contact management — Multiple phone numbers per contact, colour-coded tags, timestamped notes. Search by name or number, filter by tag. ⏰ Scheduled messages — Pick a future date and time; Contakt opens the messenger and pre-fills your message when the moment arrives. 🔔 Reminders — Quick presets (1h / 3h / 1d / 3d / 1w) or any custom date and time. Desktop notifications include "Snooze 1h" and "Dismiss". Edit or cancel any time. 📝 Templates & formatting — Save reusable message templates.

Preview before import with duplicate detection and merge options. 📞 Note to self — Save your own number once, then send notes to yourself with a single click from the header. 💾 Backup & restore — Export all contacts, templates, reminders, scheduled messages and settings. Restore on another machine and reminders rebuild automatically. 📚 History — Quick access to your recent sent messages. 🌓 Auto dark mode — Follows your system theme. 🌍 Available in 10 languages, including full right-to-left support for Arabic. 🔒 Privacy by design — Your phone numbers, contact names, message bodies, notes and tags never leave your device — everything stays in local storage. No messenger-web login required. The only optional remote channel is anonymous, opt-in usage stats (event name + platform + country code; never personal data) — off by default. No ads, no third-party trackers, no SDKs. Stop saving numbers you'll message once. Just click and chat.
