From Timestamp Manipulation to Custom Comparators: A Performance Story
While building chat ordering for WhatsApp chats in Volt, we had to choose between manipulating chat data or implementing a custom comparator. I explain how we moved away from an expensive timestamp-based approach and adopted a comparator that preserved data integrity, simplified restoration, and improved performance by 50x.
Fast Contact Creation
Saving new contacts on WhatsApp usually takes way too many steps. Volt’s new Fast Contact Creation cuts it down to just a shortcut, letting you save any new chat in under 5 seconds without breaking your flow.
Meet Volt AI Assistant: Your Companion for Smarter Chats
You asked for faster ways to reply on WhatsApp—we built Volt AI Assistant. Just hit cmd + J, your instruction, and Volt will generate replies that match your tone, language, and context for that specific chat. Whether you’re following up, rescheduling, or saying sorry, it’s like having a writing sidekick that sounds just like you.
Your muted lists now sync to WhatsApp mobile
Now you can mute entire groups of chats in Volt — like Work, Family, or Hobbies — and they’ll disappear from your WhatsApp inbox on both Volt (desktop) and WhatsApp mobile app. Stay focused by silencing lists with one click, and bring them back anytime.
