Kit
BUILT-IN AI INVOKE-ONLYKit is a platform that allows creators to automate tasks and developers to build apps for the Kit App Store.
Connect Kit to ChatGPT or Claude with your own Kit login or an API key, and your AI can run 42 of its actions. 22 of those only read and change nothing. 6 can delete or send something that cannot be undone, so those need a boundary you set before anyone runs them.
Things you could hand over
Your assistant can pull the account's growth statistics over a date range and the email statistics for the last ninety days, then read the account record for the plan and the sending timezone those numbers are reported in. Kit returns growth in your sending timezone rather than UTC, which is the usual reason a hand-built weekly count never quite matches. Nothing here writes.
Built on: Get Account / Get Growth Stats / Get Email Stats
It can list your broadcasts, read a specific one, pull its statistics once it has been sent, and pull the link click data showing which links people actually clicked. Comparing the clicks to the subject line across the last dozen sends is the version worth asking for, because the click is the part that means something and the open rate has been unreliable for years.
Built on: List Broadcasts / Get Broadcast / Get Broadcast Stats / Get Broadcast Clicks
It can filter subscribers by engagement behavior, such as no opens or no clicks over a date range you set, read the individual engagement stats behind any name on that list, and trace people back to the form they joined through. That connects the two halves of the question: who has gone quiet, and whether one particular signup path produces people who never engage. Kit only holds subscriber-level event data from June 2025 onward, so an older account has a floor on how far back this looks.
Built on: Filter Subscribers / List Subscribers / Get Subscriber / Get Subscriber Stats / List Forms / List Subscribers For Form
It can read your templates, creator profile and account colors, then create the broadcast itself. Leaving the send time empty saves it as a draft, which is the setting that matters: the same action with a future timestamp schedules real email to real people. Draft it, open it in Kit, and send it yourself.
Built on: List Email Templates / Get Creator Profile / Get Account Colors / Create Broadcast
It can read your existing tags, create the one this event needs, add or update each person by email, tag them, and add them to the relevant form. Kit treats subscriber creation as an upsert, so an existing person is updated rather than duplicated. The order matters, since the tag and form actions both require the person to exist in the account first.
Built on: List Tags / Create Tag / Create Subscriber / Tag Subscriber by Email / Add Subscriber to Form by Email
It can list the custom fields already defined, create a new one for the attribute you want to hold, and write values onto subscribers, up to a hundred and forty custom fields at a time. Renaming an existing field's label is a separate action from changing what is stored in it, which is worth keeping straight.
Built on: List Custom Fields / Create Custom Field / Update Custom Field / Update Subscriber
It can find the person and unsubscribe them, which in Kit removes them from every sequence and form and stops all email to them. Their historical data stays, and running it twice on the same person does nothing extra. Kit's own description calls this permanent, and there is no matching action to put somebody back.
Built on: List Subscribers / Get Subscriber / Delete Subscriber
It can list every tag with its creation date, count who is on each one, rename the ones worth keeping, remove a tag from specific people, and delete the ones that are dead. Two things here cannot be undone, so run it in stages: list first, rename next, and treat deletion as its own decision made against a list you have read.
Built on: List Tags / List Tag Subscribers / Update Tag / Remove Tag From Subscriber / Delete Tag / Delete Custom Field
- The connector lists sequences but exposes no action that adds a subscriber to one or reports who is currently in one. Sequence enrollment appears to happen through tags and forms, and that behavior was not confirmed.
- Broadcast creation covers drafting and scheduling, but there is no separate send action and no action that cancels a scheduled send. Whether a scheduled broadcast can be pulled back through the connection could not be established.
- Subscriber-level engagement data starts in June 2025 by Kit's own note, so an older account cannot answer engagement questions about the years before that through this route.
- Unsubscribing is available and resubscribing is not, so the reverse of the most consequential action on this page has to be done by the subscriber themselves.
- No time saving is claimed for any candidate on this page, because none has been measured.
