FamSpend.io Helper is a Custom GPT on ChatGPT that connects to your FamSpend workspace and lets you manage expenses by chat. Attach a bill, ask how much you spent in March, move an installment to next month — in plain language, with explicit confirmation before touching your data.
It isn't a marketing chatbot or a copywriter. It's an operational extension of the app, using ChatGPT as the conversational front-end.
What it can do today
| Action | Example prompt |
|---|---|
| Import a bill | "Got the gas bill, sending it over so you put it in Milan home" + PDF attachment |
| Find an expense | "When did I last pay car insurance?" |
| Analyze a month | "How much did I spend in March? Above or below average?" |
| Compare periods | "Compare March vs February on Home and Car Centers" |
| Quick add | "Add €45 of yesterday's gas to the Car Center" |
| Move a due date | "Move April's installment to the 18th instead of the 5th" |
| Search the help | "How does Smart Scheduling work?" (answers with a citation to the help page) |
How to activate it
In 30 seconds from your ChatGPT account:
- Open the Custom GPT — direct link is the button above, or search "FamSpend Helper" in the ChatGPT GPT Store
- Authorize with a tap — on the first operational message (not the first "hello") ChatGPT asks you to connect the account. Click Sign in with console.famspend.io and complete a standard OAuth flow
- Pick the workspace — if you have more than one, select the one the Helper can access
- Start asking — from that moment, Helper has context on your expenses and Cost Centers
The authorization is scoped: Helper only accesses the data you granted permission to. No bank balances, no current accounts — those are things FamSpend itself doesn't manage.
Explicit confirmation on every write
Every time Helper is about to modify your data (create an expense, move a due date, delete something), it asks first with a structured card:
I read the PDF and extracted these fields. Let me show you before saving:
Gas bill · Eni Amount: € 187.40 · Center: Milan home · Due: April 7, 2026 Category: Utilities · Gas · Recurring: Every 2 months
[✓ Confirm & save] [Edit]
No silent actions: you always see what's about to happen and you give the OK.
Reads are free, writes are confirmed
Reads (search, analytics, totals) flow without confirmation — that's the smooth conversation you'd expect.
Writes (create, modify, delete) always ask for explicit confirmation. No exceptions.
Privacy: what it sees and what it doesn't
Helper accesses only the containers and data you granted permission to. Specifically:
- Sees: expense titles, amounts, due dates, Cost Centers, associated people
- Does not see: your password, your bank account, your balances (which FamSpend doesn't track anyway), conversations with other users, data from other workspaces
- Your data is not used for training — it's in the GPT policy and in our terms
You can revoke access anytime from FamSpend settings (Account → Connected apps → Disconnect). Helper immediately stops being able to read or write on your workspace.
When to use it (and when not)
Use it when:
- You have a bill or receipt to log and don't want to fill the form by hand
- You want a quick numeric answer ("how much did I spend in March?")
- You're on the go and talking/typing is faster than opening the app
- You know what you want to do but don't remember where to click
Open the app directly when:
- You need to make multiple batch changes (the app has table views optimized for that)
- You want to see the calendar or the heatmap (visual views, a chat doesn't represent them well)
- You're doing initial setup (workspace creation, invites, roles) — better to click
What it is (technically)
The Helper is a Custom GPT on ChatGPT — a variant of the base GPT
configured with specific instructions and with access to Actions.
The Actions are API calls to console.famspend.io (OAuth 2.1
authenticated) and to www.famspend.io (anonymous, to read the public
guide).
Architecturally: ChatGPT is the front-end, FamSpend is the back-end. When you tell the Helper "add an expense", it calls our API, creates the expense, and returns confirmation. It's not an AI making up your data — it's an AI talking to your real account.
Do I need a ChatGPT account?
Yes — ChatGPT is OpenAI's, not FamSpend's. To use the Helper you need a ChatGPT account. The free ChatGPT plan has daily usage limits on Custom GPTs; with a Plus account the limits are much wider.
The FamSpend account and the ChatGPT account stay separate. The Helper links them via OAuth, but they're two different logins.
