Instinct alternative: Ezail, an AI assistant you can sign up for today

Last checked November 13, 2026. Both products change often, so check each site before you buy.

Instinct is "a personal assistant that understands what you're working on and what's important to you." You text or call it, and it handles travel, bookings, shopping and errands, often before you ask. It is invite-only and runs in the US. Ezail is an AI colleague you can sign up for today, in any country. You text it on WhatsApp, Telegram, Slack or Microsoft Teams, or Cc it on email, and it handles your inbox, calendar, calls and company tools. Your team can also share one assistant.

Instinct at a glance

Instinct is made by Spear Street Technology, Inc. in San Francisco. It has been in private beta since February 2026 and has rolled out by invitation since August 2026.

• Where you use it: text messages and phone calls. Reports also mention WhatsApp. There is no app.
• What it does: connects to your email, calendar and documents, and uses its own cloud computer, browser and phone number. It books and rebooks travel, watches fares, shops, pays with one-time cards and calls businesses for you. It is proactive, so it follows up and may text or call you first.
• Who can use it: adults in the US with an invitation. Others join a waitlist. There is no team or business plan.
• Privacy: Instinct trains on your data by default, with an opt-out. Google Workspace data and saved logins are excluded from training. Its terms appoint Instinct to act as your agent.
• Price: free for now. Instinct hasn't published plans, and its terms allow fees later.

Ezail at a glance

• Where you use it: WhatsApp, Telegram, Slack, Microsoft Teams, email and the web, connected to Gmail or Outlook and Google or Microsoft Calendar.
• Your own assistant: answers and drafts email (you approve every draft before it's sent), runs your calendar, makes phone calls, sets reminders and recurring tasks, reads voice notes, photos and files, and keeps projects up to date.
• Your team's assistant: one shared assistant per team with its own address, like ai+yourteam@ezail.com. Cc it on a thread and it does the work in the team's tools (Notion, Linear or any MCP server), then replies to everyone on the team.
• Privacy: Ezail doesn't use your Gmail or Google Calendar data to train AI models, and doesn't sell your data. It is CASA Tier 2 certified through the App Defense Alliance.
