Perisclaw is an AI-powered executive assistant designed to work inside WhatsApp, where it uses conversation context to help people manage commitments and follow through on tasks. It connects with tools including calendars, email, Google Sheets, Drive, Notion, and Slack, bringing information and actions together without requiring users to leave their chats. People can give it instructions by text or voice note, from setting reminders and scheduling messages to summarising and forwarding conversations.

The service can track tasks and obligations, coordinate or reschedule meetings, run recurring automations, and handle longer assignments that involve follow-ups across conversations. It also helps users save links, notes, and documents as a personal wiki, recall details about relationships, and build a personal memory of preferences and communication habits. Perisclaw additionally offers WhatsApp MCP connections to AI tools such as Claude, Codex, and Cursor. Its stated security features include encrypted, isolated user containers, granular controls over chat access, and safeguarded runtime execution.
