Meet Tab — The Personal AI Assistant Race Heats Up With a Brand New Sidekick

The Evolving Landscape of Personal AI Assistants

The race to build the ultimate personal AI assistant capable of managing your everyday life is getting increasingly crowded. While established heavyweights like Meta Muse and Instinct AI vie for consumer attention, a fresh and ambitious competitor has officially entered the arena.

Emerging from stealth with an impressive $300 million valuation, Tab has secured backing from prominent investors including SV Angel, Valar Ventures, and American Spirit. Founded by Brennan Erbz, Stafford Schlitt, and Ammar Amdani, this consumer AI startup is aiming to redefine how people interact with artificial intelligence for productivity and everyday tasks.

How Tab Works: Messaging Apps Over Separate Interfaces

Unlike traditional AI assistants that require users to open a dedicated, standalone application, Tab is engineered to operate seamlessly through the messaging platforms you already use daily. Currently supporting major channels like iMessage and WhatsApp, the assistant lets you text requests much like you would a real-life friend or colleague.

The concept is refreshingly straightforward: send Tab a message outlining what you need accomplished, and the AI springs into action. Whether you want to find and book a flight, call a hotel to modify a reservation, convert a complex PDF into an organized spreadsheet, or track down a rare replacement part, Tab handles a surprisingly robust range of tasks.

Key Capabilities and Features

Tab distinguishes itself through a dedicated compute environment and an integrated browser. This infrastructure empowers the assistant to autonomously open websites, interact with connected user accounts, and execute multi-step background tasks even when you close the chat thread.

• Multimodal Input Support: Users aren't restricted to simple text prompts. Tab accepts photos, screenshots, PDFs, and videos to accomplish tasks or generate new content.
• Phone Call Capabilities: Tab can make real phone calls to hotels, doctor offices, or vendors, wait on hold, handle inquiries, and text you back with the results.
• Secure Transactions: When asked to purchase items, book reservations, or pay invoices, Tab displays clear transaction details—including cost and vendor—requiring your explicit approval before finalizing the payment.

Tab vs. Meta Muse: A Difference in Philosophy

While competitors like Meta Muse lean heavily into acting as persistent AI companions designed for ongoing conversation and personalization, Tab positions itself strictly as a task-oriented utility. Muse follows a "talk to me about yourself" philosophy, whereas Tab focuses purely on execution: "give me the task and I'll handle it."
