Not what you were looking for?

October 9, 2026

Somebody invited you to a circle, or you want to study with one other person. This is what a circle is from the inside: what you can see, what arrives in your inbox, and the two quite different reasons posting sometimes stops.

Without a plan: A Buddy Circle — two people, one per account

Being IN a Learning or Institution circle is free; creating one needs a teaching seat or a school.

There are five kinds, and they are not interchangeable

What each kind is for
KindWho is in itWhat it has
Learning CircleA tutor and their learnersRoster, homework, a shared timeline, a class leaderboard
Buddy CircleYou and one study partnerA shared board and a timeline. Free, and the only one you can create yourself
Family CircleA parent and their childrenThe family view, child profiles
Institution CircleA school’s classEverything a Learning Circle has, run by the institution
Community CircleAnyone, around a topicAn open feed of posts, comments and reactions

The Buddy Circle — the one you can make yourself

This is the free tier’s one collaborative entitlement and it is easy to miss. Any learner on any plan can create a Buddy Circle: a private space for exactly two people, invite-only, with a shared board you can present to each other and a timeline of what you have done.

One per account, two people in it, and always private — there is no public or unlisted setting for it. It is deliberately small: a study pair, not a class.

Scheduled lessons and the agenda

A circle can hold scheduled sessions, and the agenda is where they live — what is coming, what has been, and what the session is about.

Times are shown in your timezone, not the organiser’s. That matters more than it sounds in a circle spanning several countries, which is the ordinary case for online tutoring, and it is the one place a scheduling feature is most often got wrong.

What arrives in your inbox

Two reminders per scheduled lesson: one on the morning of, at 08:00 in your own timezone, and one about an hour before it starts. The morning one is so you can plan the day; the hour one is so you actually turn up.

Beyond that, a circle emails you when a tutor sets homework or something happens in it. Nothing else — there is no promotional mail from a circle and no re-engagement drip.

Muting, and being removed

You can mute a circle, which stops its mail without leaving it — the right move for a cohort you want to read when you choose rather than be told about.

An owner can remove a member, and a removed member loses access to the circle rather than having their own record deleted: your progress, your lessons and your account are yours and are not part of the circle. Leaving or being removed costs you nothing you made.

Why posting sometimes stops — and the two different reasons

A circle can be locked, and locking stops writing only. You can always still read what is there; a lock does not take the room away.

There are two locks and they mean entirely different things. Telling them apart saves a confusing conversation with your tutor.

The two locks
LockWho applies itWhat clears it
A safeguarding lockThe tutor or owner, by hand — to cool a room downThe tutor, whenever they choose. They can still post themselves while it is on.
An unpaid-seat lockNobody by hand. The nightly sweep sets it when the circle’s owner cannot pay for the seats it holds.Paying for the seats. The tutor cannot clear this one and is not exempt from it either.
They are separate on purpose. One column for both would mean a tutor who owes for seats could clear their own debt with the button that cools a room down — and topping up credits would silently undo a safeguarding decision.

If the circle has under-16s in it

Some features need the circle to be cleared first — somebody eligible has to take responsibility for the children being there. That is the tutor’s or the school’s job, not yours, and if a feature is refused the message names what is missing so they can fix it.

While a child is in the room, moderation fails closed: if the safety check cannot run, the message does not post. That costs an adult a minute occasionally and is the right way round.

Common questions

Yes — a Buddy Circle, one per account, for you and one study partner. Learning and Institution circles are created by tutors and schools.
