Slack, Teams and WhatsApp alternatives, compared honestly.
How SphereOne compares with the apps teams use today: what each one does well, where SphereOne is different, and how to switch without losing your history.
The short answer
SphereOne is an AI-native alternative to Slack, Microsoft Teams, WhatsApp, Google Chat, Mattermost, Discord and Telegram for businesses that want team chat, video meetings, files, a calendar and client rooms in one workspace the company owns. Its assistant, SphereOne Assist, works inside every conversation on paid plans, and each of those apps’ history can be imported, previewed first and undone.

Questions about switching
What is the best alternative to Slack and Microsoft Teams?
For businesses that want team chat, video meetings, files, a calendar and client rooms in one workspace, with an AI assistant on every paid plan, SphereOne is built for exactly that. Teams that must host their chat themselves are better served by Mattermost or Rocket.Chat.
What can replace WhatsApp groups at work?
A workspace the company owns. In SphereOne, client and project groups become rooms with work accounts, admin control and history that stays when people leave, and each WhatsApp group’s export can be imported.
Can we switch without losing our chat history?
Yes. SphereOne imports from Slack, Microsoft Teams, WhatsApp, Google Chat, Mattermost, Discord and Telegram. You see a preview before anything is written, set a cut-off date for the day you switch, and can undo any import.
Is SphereOne free?
Yes. Free covers up to 10 people with 30 days of message history, 5 GB of storage and meetings of up to 5 people; it doesn't include AI. Paid plans are Starter US$8 and Business US$15 per person a month, and you can try Business free for 14 days.
