ChaptOS holds the whole org — roster, dues, meetings, events, service, docs — and opens on a briefing: what's late, what's this week, who's slipping. Everything else is one question away.

🍕 🎉 "dues i think"
Nobody signed up to be an admin.
You ran for this because you cared about the org. Then the org turned out to be a filing system with a social calendar attached.
Composites of the officer workload ChaptOS was designed around — not customer quotes.
I spent two hours matching Venmo notes to a spreadsheet. One said "🍕".
Attendance is a notebook. The notebook is in someone's car. The car is in Ohio.
Minutes live in three people's Notes app. Nobody agrees what we decided.
New treasurer asked where the money was. Honestly? Four places.
Our whole system was one senior's Google Drive. She graduated in May.

I approved an $84 reimbursement over text and never wrote it down. The balance lied for a month.
Half the exec board can't find last year's event budget. It exists. Somewhere.
Every term we rebuild the same roster sheet from scratch.
Sent dues reminders to nine people who'd already paid. Great look.

Ask your org
a question.
No more digging through spreadsheets. Just ask Chapt — it finds the answer, or handles the task for you.
- 1You ask, in plain words
- 2It checks the real records
- 3You get an answer with receipts
- 4You ask it to do something
- 5Nothing sends without your OK
- 6It follows up so you don't
Priya · Treasurer PS
✳ ChaptOS
Checking before answering
- Read 52 dues records for Fall 2026
- Matched 6 unlabeled payments to members
- Applied your Oct 1 late-fee rule
4 are past the late-fee date.Needs a nudge
6 more · every row opens the payment it came from
Priya · Treasurer PS
Waiting on you — ChaptOS never sends on its own
Hey Maya — no stress, just a heads up that Fall dues ($140) are open past the Oct 1 date. Payment plans are totally fine; reply here and we'll split it into three. 💛 — Priya
That's four tabs, two spreadsheets and a guilt-ridden group text — collapsed into one sentence.
Nobody logs in to use software.
They log in because something's due, someone paid, roll needs taking, and the minutes have to say what we decided. Here's an ordinary day, in the order it actually happens.
The briefing says what's late

Approving writes the expense row and moves the balance — one transaction, both books
Dues payments and payouts are requests until a treasurer approves them. Nothing edits the balance behind anyone's back.

Standing updates itself as the roll closes — so the attendance policy is finally a number, not an argument.

What the secretary typed
ok so formal — voted, 31 yes 6 no, we're doing the 23rd not the 30th…
maya asked about payment plans, priya says fine, 3 splits, needs a vote next week
dev has to send the budget to advisor by friday!! also someone confirm the van
alumni mixer moved to confirmed, dr owns it
Decisions
- Fall formal set for Oct 23 31–6
- Alumni mixer confirmed, owner D. Reyes
Action items
- Budget to the advisor by Fri Treasurer
- Confirm the van + 2 drivers Social
Discussed
- Three-split payment plans — vote next week
Action items were handed to the seat, not the person — whoever holds Treasurer next month inherits them
Two of those action items are now dated tasks. They'll be on tomorrow's briefing whether anyone remembers or not.
11:58 PM · Timeline
Nobody wrote a status update. This is just what happened, in order.
Next May, the incoming board reads this instead of interviewing whoever still answers texts.
Five officers, six surfaces, one ordinary day — and not one of them opened a spreadsheet.
A day runs itself.
A semester is what piles up.
Every moment on that dial took one person a few seconds. These three are what those seconds add up to by April — the money, the people and the record — and what the next board opens on their first day.
Two sets of books that can't disagree.
A running balance for every member, and one ledger for the whole org — wired together so they move at the same time. A dues payment or a reimbursement is a request until a treasurer approves it; approval mints the matching row and adjusts the balance in a single write. Nothing gets hard-deleted.
- Reimbursements and dues payments sit in one approval queue — approve to mint the ledger row, decline with a reason
- A semester budget split by category as a percent of the pool, with a reserve target and burn-rate per bucket
- Charge or waive a balance with a reason attached, never a silent overwrite — plus a CSV export your advisor accepts without a screenshot

Everyone's whole story, one row each.
Attendance, dues, service hours, GPA and anything else you decide to track, per member, per term — with the bands you set for on-track, watch, and at-risk. Open anyone and you get their history, not a number somebody typed.
- Your own member fields and your own metrics — jersey number, section, major, anything
- Roles carry fourteen permission switches and a rank, so nobody can promote themselves

Treasurer sees money + roster · Service chair sees her committee · nobody sees more than their seat
The org shouldn't reset every May.
Bylaws, forms, vendor links and minutes live in a foldered library anyone can search. Every change writes an entry with who and when. Terms archive instead of vanishing — last year is still readable while this year starts clean.
- Drag-and-drop filing, pinned essentials, link previews, contributor credit
- An activity log the whole board can read — no "who changed this?"
- Ask about last year: "what did we spend on formal in 2025?"

Roster, ledger, attendance and docs export to CSV any time — including on the way out
Plus tasks, polls, service hours, party books, a social calendar, role permissions, several orgs on one login, and a phone app that isn't a squeezed dashboard. A 12-person committee and a 200-member chapter run the same pages — just fewer of them, and turning one on mid-term doesn't cost you the history. See every page
You describe the org.
It writes the workspace.
Setup is a short interview, not a settings tour. Answer what your org actually does in a normal month and it drafts the pages, the seats, the words your org uses, your timeline categories and your first term — then shows you the whole blueprint to edit before anything is built.
What kind of organization is this?
In a normal month, which of these actually happen?
How does your year break up?
Free text works too — describe the org in a sentence and it asks the two or three specific follow-ups it needs to settle the page set. If the model is having a bad day the interview keeps working; it just stops guessing.
You build the whole thing signed out. Google sign-in happens at the final step, and your answers survive the round trip.

An assistant holding your org's money should be boring about it.
ChaptOS proposes; officers decide. Every number traces back to a record, every action lands in a log, and nothing writes without a human who's allowed to.
It can't act alone
Anything that touches money, members or the outside world arrives as a proposal with an Approve button — and it's checked against your seat before you ever see it. If your role can't do it, the card says so and names who can.
Every answer shows its work
No confident guesses. It reads your actual records, posts what it read as it goes, and every figure opens the payment, the meeting or the member it came from — so "where did this number come from" is a click, not an argument.
Your org, your data
One org can't read another — that's enforced at the database, not just in the UI. Inside yours, seats decide who sees what. Roster and ledger export to CSV any time, and deleting the whole workspace is one confirmation away.
Read the full trust & privacy pageEvery mechanism named, plus the things we don't claim yet.
One price for the whole org. No per-person math.
Free while there are 4 or fewer of you, then $25 a month for everyone — not each. Every feature is in every row.

Let's talk
Priced with you, not off a table.
You never pick a row. Your roster lands you on one, and it moves you between them on its own — in both directions.
Every feature at every price
The roster, dues and the ledger, attendance, the timeline, docs, the assistant, exports, the audit log — on the free plan too. No screen tells you to upgrade to see it.
Nothing is taken away at the limit
Cross the free line and the next person you add waits for a card. Nobody is removed, every page keeps working, your exports keep working. It only ever pauses growth.
It follows you back down
Seniors graduate, your headcount drops, and next month's invoice is smaller. You don't have to ask, and there's no plan to downgrade.
See the full pricing pageWork out your own number, who counts as a person, and what happens above 120.
Fall term starts in — daysMid-term is the second-best time to start
Be the board that
didn't inherit a mess.
Setup takes an afternoon. Describe the org, bring your people in, and walk into your first meeting with the roster, the dues, the calendar and the record already in one place.
This week
Describe your org
A short interview drafts your pages, seats, vocabulary and first term. You edit the blueprint, then sign in. ~20 minutes.
Before day one
Bring your people in
Paste the roster from whatever sheet you have, or send one invite link. Seats already carry their powers, so exec is exec on day one.
Week one
Just open the dashboard
It tells you what's late and what's this week. You spend the term on the org instead of on the spreadsheet about the org.
