A calendar secretary you copy into a thread or text, who books the meeting and chases the reply
Howie is an AI agent you reach on iMessage, SMS and Email. To start, create an account. It messages you first rather than waiting to be asked.
How Howie works
Howie is a scheduling secretary you copy into an email thread rather than an assistant you open. It reads the thread, checks availability, offers times, handles the replies and books it, and answers on iMessage and SMS as well as email. It is the only listing here whose primary channel is somebody else's inbox.
The pricing is the thing nothing else in this directory does. It is $25 a month for a shared workspace with unlimited teammates, and what varies between tiers is credits rather than seats: the same monthly figure buys 1,250 credits at the bottom and 150,000 at the top. Everywhere else here charges per person or per month for a fixed product, and this charges for work done.
Its privacy policy is the oldest in the set, dated September 2025, which predates most of the product it now covers. It is also one of the more thorough, publishing a table of every category of personal data against the purpose and the third parties who receive it. What it does not contain is a training statement, a model provider or a messaging provider, so three of the rows a reader would want are empty in a document that answers almost everything else.

Howie’s own pages answer 4 of the 9 questions this site asks of every listing. Not answered: says whether it trains on you, says what happens if you cancel, names who carries the messages, names its model providers, says where to report a bug. Fewer than most of its kind: 8th of 8 scheduling.
