Wajo vs Muse AI vs Grok Bot vs Dots: Which AI Agent Should You Pick?

The four agents in one paragraph

Wajo's Fo, launched September 29, 2026 by ex-DeepMind engineering lead Shivani Poddar, is an action agent: it makes phone calls, sends emails, books appointments, places orders, and processes payments with single-use cards — and escalates to a human executive assistant when it can't finish. It is free today and invite-gated.

Meta's Muse AI, launched September 8, 2026, is the polished personal agent most people will meet first: a free tier (with usage limits), apps on iOS and Android, web, and WhatsApp, with background Goals that work while you're away and approval cards gating anything consequential. Available in the US and Canada.

Grok Bot, xAI's agent product (beta since August 11, 2026), is built for parallel work: several named AI teammates in one thread hand tasks to each other, with per-action approvals. Access rides on paid plans — SuperGrok from $30/month or Cursor Pro from $20/month — with no free tier.

ChatGPT Dots, launched at OpenAI's DevDay on September 29, 2026, are always-on agents on GPT-6 Astra with their own cloud computer and browser, 4,000+ app connections, and proactive read-only background research. Your first dot is included with ChatGPT Pro (from $100/month) or Business Premium ($125/seat).

Wajo vs Muse AI: the main event

This is the comparison most people are actually making, because these are the two agents a normal person can start using this week. The split is clean: Wajo does things Muse can't, and Muse does things Wajo can't.

Wajo's edge is the phone. Booking a restaurant, chasing a delivery, negotiating with a vendor — anything that requires calling a business and talking to a human — only Fo attempts, and its human-assistant fallback means a stuck task still gets finished. Muse has no outbound calling. Wajo is also free today with no published pricing, while Muse's free tier has usage limits and paid tiers run $20–$100/month (press-reported).

Muse's edge is maturity and surface area. It has native apps, WhatsApp, a documented safety architecture (approval cards plus the Sentinel guard layer), and Meta's distribution behind it — it is the agent you can install today and hand to a non-technical family member. Wajo is a weeks-old startup product: regions, waitlist mechanics, and future pricing are unpublished, and its 71% task-completion figure is the company's own fieldnotes, not independent testing.

The honest read: if your week involves phone calls to businesses, Wajo is the only option of the four — there is no contest. If your needs are messages, research, reminders, and background errands, Muse is the safer, more available pick today. Many people will end up using both: Muse for daily life, Wajo for the calls.

Wajo vs Grok Bot

Different planets. Grok Bot is for people who want several agents working in parallel — 2 to 6 named teammates per thread, scheduled routines, xAI-centric workflows — and it assumes you're technical enough to enjoy that. Wajo is for people who want one errand finished: the plumber booked, the refund chased, the flight rebooked.

Price separates them cleanly: Wajo is free today; Grok Bot has no free tier and starts at $20–$30/month. Grok Bot has no phone calling and no human fallback; Wajo has both. If you like orchestrating agent teams, Grok Bot is the interesting one. If you want the plumber booked, Wajo.

Wajo vs ChatGPT Dots

This is the work-tooling matchup. Dots live where your work already happens — ChatGPT, Slack, Teams — with 4,000+ app connections, standing goals, and proactive background research. Wajo lives where your errands happen — the phone network, email, booking sites — with a human safety net.

The price gap is the widest in this comparison: Dots start at $100/month (ChatGPT Pro) while Wajo is free today. Dots can't place phone calls; Wajo can't see your Slack. A professional who lives in ChatGPT and Teams buys Dots for work projects and could still use Wajo for personal errands — they solve different halves of the week.

Wajo invite code: how to join

1. Open the invite link: wajo.ai/join — the code is built into the link.
2. If you're asked for an invite code during signup, enter 2VJ5NW5G.
3. Connect your Google Workspace so Fo can build context about you over time.
4. Your plan shows as 'Fo mini' with 1,000 tasks per day, and Settings has a 'Have a code to upgrade?' field for higher tiers.
5. Start with something small and phone-shaped — a restaurant booking or a delivery chase — so you can watch how Fo (and its human backup) handles it before handing over anything important.
