Book club host admin shouldn't take longer than the discussion

Most book clubs run as group chats with someone counting "yes" replies before each meeting. It works for the first six months. By month nine you have 14 active members, four of whom are silent, two of whom you accidentally text the wrong location, and the host of next month's meeting needs to know dietary preferences for 12 people.

Who's In gives book clubs the same easy WhatsApp-shareable RSVP experience that running clubs and yoga studios use, but tuned for how book clubs actually work. Recurring monthly meetings with rotating hosts. Host's-house capacity (8 in a small lounge, 14 if it's the dining room). Dietary collection for potluck-style meetups. The book of the month visible on the booking page so members never forget what to read.

Free forever for free meetings. If members chip in for the host's wine through Stripe, it's 2.7% plus Stripe's card processing on what's collected.

Sound familiar?

You're not alone. These are the challenges we hear every day.

WhatsApp threads bury the meeting details

Half your group chat is about the book. Half is about Sarah's new puppy. The actual meeting time + address is somewhere in the middle, only mentioned twice, three weeks ago.

Meeting details lost in the chat

Host's house has a capacity. WhatsApp doesn't.

Sarah's living room holds 8 comfortably. Your group is 14. Without a way to cap the meeting, you're either over-crowded or watching the most enthusiastic readers fight to confirm first.

More readers than chairs

Dietary preferences are a manual chase

Sarah's hosting and asking what everyone wants. Three vegetarians, one gluten-free, two who hate olives. By the time she's collected this in the chat, half the answers are buried.

Dietary answers buried in replies

Half the group forgets what book they're reading

You voted on the book six weeks ago. Three days before the meeting, two members message: "wait, what's the book again?" Now you're scrolling back through the chat to find the title.

"Wait, what's the book again?"

Built for the way book clubs actually meet

Recurring monthly meetings

Monthly on the same date, set up once: up to 12 meetings are created together. Edit one specific month's host or location without breaking the recurring pattern.

Per-meeting capacity caps

Sarah's hosting in May (capacity 8). David's hosting in June (capacity 14). Each meeting gets its own capacity. Auto-promoting waitlist when someone drops.

Current book + reading list pinned

The book of the month displays on the meeting page. Add a reading list of upcoming books. Members can find both at any time without scrolling through chat.

Dietary collection at signup

Switch on the dietary and allergy questions at signup. The host sees every answer on the dashboard and in the CSV export.

Reminder before the meeting

Members get up to three email reminders: a week before (when the meeting is that far out), the evening before and the morning of, with the date, time and address. Signed-in members who add a phone number and keep WhatsApp notifications on also get the morning-of reminder on WhatsApp.

Zero app — works in any browser

Members tap your link in the WhatsApp group, RSVP in two taps, done. No download. No account. No password. Their RSVP is in their email.

Three book clubs, three setups

Neighbourhood book club, 14 members

Free Events tier. First Tuesday monthly. Rotating host (so capacity changes per meeting). Dietary collection. Reading list visible. Free for everyone.

Author-talk subscription, $20/quarter

Studio plan ($15.83/mo annual). Quarterly author guest speaker. Members pay $20/quarter via Stripe for the author's appearance fee. Capped at 25 attendees per session.

Charity-themed book club fundraiser

Free Events tier with paid bookings. Annual fundraiser meeting at a venue, $25 per attendee, proceeds to literacy charity. Who's In's 2.7% is about 68¢ a ticket, plus Stripe's card processing.

Why book clubs leave WhatsApp polls + email

vs WhatsApp polls

Fine for 6 friends. Breaks fast at 12+ active members. No capacity caps for host's-house meetings, no waitlist, no dietary collection. The book of the month is buried in the thread.

vs Eventbrite

Built for ticketed events with hundreds of attendees. Overkill for a 14-person book club. Every RSVP goes through a checkout. Too expensive for free meetings.

vs Google Calendar invite

No RSVP confirmation, no capacity, no dietary collection, no reminder beyond the calendar event. Members "tentatively" accept and never actually confirm.

“I love this app! It's perfect for organising events from walking groups to theatre trips, parties to weekends away. The plus one feature is brilliant. It takes all the stress out of organising events.”

Frequently asked

Real questions from book club hosts.

Is it really free for our monthly meetings?
Yes. The Events tier is free forever for free meetings. Unlimited meetings and RSVPs, with up to three automatic reminders: a week before (when the event is that far out), the evening before and the morning of. The 2.7% fee only applies if you collect money — for example, $5/person for the host's wine fund or a $20 author-talk fee.
Can different members host with different capacity limits?
Yes. Each meeting has its own capacity. Sarah hosts May at capacity 8 (small lounge). David hosts June at capacity 14 (dining room). Auto-promoting waitlist if anyone drops out. Each meeting page also shows the host's address.
Can I show the current book on the booking page?
Yes. Each meeting has its own description where you can add the book title, author, and any host's notes ("snacks provided, BYOB"). Add a reading list for upcoming books so members can plan ahead.
What about collecting money for the wine + cheese?
Add a price per attendee — say, $5 toward the host's wine fund. Stripe handles checkout. Funds go straight to the host's account. Or set it free and collect cash on the night.
What if a member can't make it last-minute?
They tap "drop out" on their RSVP. The waitlist auto-promotes the next person. Both get email confirmations. The host's confirmed list updates automatically.
