Fo by Wajo vs Comma

Both promise a personal agent that does work for you rather than just answering. They are built around different jobs. Fo is pitched at errands that involve other people, such as booking a dentist, calling a plumber or sending flowers. Comma is pitched at ongoing work across your apps and files. This guide sets out what each vendor publishes and what remains unknown.

Choose by the job

If the job involves calling or emailing other people

Wajo's page describes Fo handling "the back-and-forth with the people involved" by group chat, call and email, and lists errands such as booking a haircut, getting three quotes and cancelling a gym membership. Comma's page describes work inside your own apps, such as triaging tickets, reviewing documents and drafting replies, and does not describe phoning third parties. For errands that need a counterpart, Fo is the one whose vendor documents it.

If the job is ongoing knowledge or project work

Comma describes Tasks that continue on a cloud computer, a board with Backlog, In progress, Needs Review and Done columns, morning Routines and proactive messages when something needs you. Wajo's consumer page is organised around single errands instead. Its business offering describes building agents for operations work, which is a separate product from Fo.

If you need a human backstop

Wajo says its team steps in when a task cannot be completed with AI alone. We did not find the terms for when a human sees your task data, so confirm that before sending anything sensitive. Comma's page does not describe human escalation.

If you care most about spending controls

Wajo describes one-time payment cards, so a merchant does not receive your real card details. It also says real-world tasks use credits. The page does not give the credit rate or the charge for human help. Free plans are not free transactions. We did not find a spending limit setting on either page.

What is still unknown

Questions to ask before connecting accounts

  1. Which actions run without my approval, and where do I change that?
  2. If money is spent, what is the maximum per task, and who bears the cost of a mistake?
  3. Who can read my task content, including any human helpers?
  4. What is deleted when I disconnect an app or close the account?
  5. What does it cost after any free allowance?
