Spike overview

What is Spike?

Spike is an AI-powered email application that unifies your inbox, calendar, and collaboration tools into one seamless workspace. Built for professionals and teams who live in email, Spike keeps communication fast, organized, and context-rich—without forcing new systems or migrations.

Spike reimagines traditional email as chat-style conversations, removing redundant headers and cluttered threads for cleaner, real-time communication. You can reply instantly, track updates, and collaborate naturally while maintaining full compatibility with Gmail, Outlook, iCloud, and any IMAP account.

Integrations & Compatibility:

Spike works with all major email providers (Gmail, Outlook, iCloud, Yahoo, IMAP) and integrates with your native calendar. All tools sync automatically across devices for consistent, secure access anywhere.
