You already do the hard part. Here are the tools.

Paste in names and email addresses, up to 500 at a time. You see the whole thing before anybody is emailed , exactly who will be invited, who will be skipped, and why. Everyone who comes in this way is admitted on your word, with no queue and nothing for you to tap. Run it again next week for the stragglers and nobody is asked twice.

And your group’s history comes with it (the recommendations, the for-sale posts and the answers buried in the chat) so the circle starts full rather than empty and nobody arrives to a blank room wondering why they moved. Members decide whether their own old posts stay visible, so what comes across is theirs rather than ours.

Drop it into the WhatsApp group. Whoever taps it joins, admitted on your vouch, with nothing for you to approve one person at a time. The link expires, you can switch it off, and there is a daily ceiling so it cannot be passed around beyond the group.

Everything else a host does is on this one screen rather than in your head: who is waiting, who is in, up to five co-hosts to share the load, announcements that stay at the top of the feed, and, if you ever want to step back, handing the circle to a co-host properly instead of going quiet on three hundred people.

Not a pinned message that was gone in a fortnight. You write them once, in your own words, and they sit on the circle: every member agrees to them when they join and can read them any time after without asking you what they were.

Up to twenty lines. Most groups need five.

When a member reports something it comes to you with the post, who wrote it, why it was reported, how many people reported it, and two buttons. Keep it, or remove it. No scrolling back through a thousand messages to find what somebody meant.

Members can also block each other, go quiet for the evening and leave without messaging you first. Most of what currently lands in your DMs stops being yours to do.

Admitting someone to a 300-person group hands their mobile number to 300 strangers, and hands them 300 back. It is the objection you field most often. On Kinli, no member ever sees another member’s phone number , there is no setting that shows it and no screen that could. A number someone adds to their own account is seen by them and by Kinli, and nobody else. Messages happen in the app, and are encrypted where they are stored.

Then one switch seals the circle: posts can’t be shared out as a link, forwarded into a message, or surfaced anywhere outside it. What the switch can’t do is written on the same screen rather than in a help page: a screen grab can’t be blocked on any iPhone, so Kinli tells the circle who took one instead.
