Everything Alfera does
- A company brain that syncs your apps. Connect Google Drive, Notion, Slack and the rest. Documents sync on their own, keep every version, and every answer draws on them.
- One coworker for the whole team. It knows who is asking. Many people, many tasks at once, each with their own chats and connections, and shared chats when you want.
- 3,000+ app connections, shared the way you choose. Each connection is open to everyone, one project, or one person. A personal mailbox stays personal; the support inbox is the team’s.
- Permissions on every action. Allow, ask first, or never, per connection and per action. Approvals land in Slack, email or the app, and every action is logged.
- Where your team already is. Slack, WhatsApp, email from its own address, the web app, a Mac app, and your own code through the API and MCP.
- It starts work by itself. On a schedule, from a webhook, or on 600+ app events in Gmail, HubSpot, Stripe and more.
- Its own computer. Every chat runs in a sandbox with a terminal and a browser, and its files stay from one chat to the next.
- Any model. 230+ models: Claude, GPT, Gemini, open models, your ChatGPT plan, or a model you run yourself.
