# Synchronize > Synchronize is a community platform for professional communities. It connects Slack, email, and an online community so members can participate where they already work while sharing one conversation, member identity, and operating layer. Website: https://synchronize.so/ Contact and demos: https://synchronize.so/get-started ## What Synchronize does Synchronize keeps community posts, replies, edits, reactions, authors, and timestamps aligned across Slack, email, and the community web experience. Members can participate from their preferred channel without creating disconnected copies of the conversation. Community teams manage onboarding, messaging, spaces, members, search, and analytics from one system. Synchronize is best suited to professional communities that want to improve participation without requiring every member to adopt the same communication habit or repeatedly visit another destination. ## Product options - [Synchronize for Circle](https://synchronize.so/product-circle): Extends an existing Circle community into Slack and email while Circle remains the community home. Best for communities already using Circle. - [Synchronize for Slack](https://synchronize.so/product-slack): Keeps Slack as an active participation surface while adding a lasting web home, email participation, directories, search, and analytics. Best for Slack-centered communities. - [Synchronize Core](https://synchronize.so/product-core): A fully branded community platform with Slack and email built in, plus managed member and content migration. Best for teams launching a new home or moving from another platform. - [Product overview](https://synchronize.so/product): Compares the three ways to adopt Synchronize. ## Core capabilities - Cross-channel conversations: Synchronize posts, replies, edits, reactions, authors, and timestamps across supported community surfaces. - Slack participation: Membership activation, profile sync, post and comment sync, channel and space management, welcome messages, event channel syncing, member directory access, and community search. - Email participation: Create posts and replies by email; offer daily, weekly, biweekly, real-time, or all-message delivery options depending on plan; support branded sending on the Pro plan. - Community operations: Analytics, member management, onboarding workflows, application forms, directories, space management, mass email, and mass Slack direct messages. - Ask AI search: Turn community conversations and resources into cited answers and help identify members with relevant experience. Available on Standard and Pro; token limits apply. - Enterprise controls and services: Custom domain, dedicated email IP, custom SSO, priority support, white-glove onboarding, and migration support on qualifying plans. ## Integrations and participation surfaces - Circle: Synchronize can use Circle as the online community home and connect its members, spaces, and conversations with Slack and email. A separate Circle Business license is required for all Synchronize plans. - Slack: Members can participate in connected community conversations and access supported community workflows from Slack. - Email: Members can receive community activity and participate by posting or replying from their normal email client. This works with standard email clients rather than requiring a particular inbox provider. - Web community: Depending on the selected product, the web home can be an existing Circle community or a fully branded community delivered with Synchronize Core. Synchronize does not claim that Slack, Circle, or any email provider owns or endorses Synchronize. Product and feature availability depends on the selected plan and implementation. ## Why teams choose Synchronize - Meet members where they already are instead of forcing a single platform habit. - Preserve one shared conversation rather than splitting engagement into duplicate threads. - Make participation accessible to Slack-first, email-first, and web-first members. - Give community operators one view of engagement across connected surfaces. - Add an operating layer around an existing Circle or Slack community, or migrate to a complete branded community platform. - Support growing professional communities with onboarding, search, analytics, messaging, and hands-on migration services. ## Pricing Pricing scales by plan, billing frequency, and community size.
