Description
Spike is an AI-powered email and collaboration platform that reimagines the inbox as a unified, chat-style workspace. It turns long email threads into messenger-like conversations grouped by people, and brings email, messaging, docs, tasks, video calls, and AI tools together in one place so teams can avoid switching between multiple apps.
Spike AI helps you work faster with smart inbox sorting, instant summaries of unread emails and long threads, and contextual drafting of messages and replies. Beyond AI, it offers a unified inbox that connects multiple email accounts, a priority inbox, super search, reminders, snooze, built-in translation, message templates, and an integrated calendar.
For teams, Spike provides channels and groups, collaborative notes and tasks, a shared inbox for managing team email together, and built-in video and audio calls with no scheduling links or downloads. You can add non-Spike users to groups and calls, so you can work with clients and vendors who don't use the app. Spike can upgrade an existing Gmail, Microsoft, or other account, or provide a business email with a custom or @spike.team domain.
Spike is available on mobile, desktop, and web, with data protected by AES-256 encryption. It offers Teamspace plans (Starter, Team, Business) and Email App plans (Free, Pro, Ultimate), with paid tiers starting from around $4 per member per month and the free Starter tier including 10 AI queries.
