Billy - 2026 Pricing, Features, Reviews & Alternatives

Billy is an AI assistant that integrates with Slack, Gmail, Google Calendar, Google Meet, Zoom, Microsoft Teams, and GitHub to give teams a shared knowledge layer across channels, direct messages, email, calendar events, and meeting transcripts. Every piece of information Billy surfaces is subject to permission checks that mirror each user's existing access rights, so no one gains visibility beyond what they already had. During a pilot period, Billy runs on FastCode AI's servers; after the pilot, it deploys on the customer's own infrastructure using local AI models, keeping all company knowledge and AI processing entirely within the organization. Meeting recordings are stored on customer machines or customer-owned AWS storage and are never used to train external models.

Billy addresses the recurring overhead that falls on founders, managers, and operations leads by giving the entire team a single assistant to query instead of routing questions through individuals. It joins meetings automatically from the calendar, then posts summaries and action items with assigned owners directly to Slack. Scheduled workflows can be defined in plain English and configured to run on intervals ranging from every 30 minutes to daily, weekly, or a fully custom schedule. Workflows support conditional logic, Slack List management with owners, statuses, and due dates, polls, teammate follow-up chasing, calendar invite handling, and canvas clean-ups. Billy asks for confirmation before executing any irreversible action. Built on LighthouseOS by FastCode AI, a team with publications at CVPR and NeurIPS, Billy is suited to product and operations teams that require both automation depth and strict data residency controls.
