Once you connect Magica to your AI assistant, something clicks: you stop tapping through screens and just ask. And because the answers come from your own data — on your phone, no cloud in the middle — it’s a bit like having a mechanic, an accountant and a personal assistant who’ve quietly memorised every receipt, every trip and every deadline, and who live in your pocket.

Here are ten things I ask Claude about my car. The first seven are questions (read-only). The last three actually change your data, so they need a read-and-write token.

Ask it anything

1. “How’s my car this month?”
A full check-up in one line: odometer, kilometres driven, trips, fuel spend, total cost, anything overdue. One question, and you know exactly where you stand — no menu diving.

2. “How much have I spent on fuel this month?”
The number you’d otherwise get by adding up receipts in your head, delivered instantly from your logged refills.

3. “Am I burning more fuel than usual?”
It compares your real consumption to the manufacturer’s figure and to last month — turning a vague worry (“feels like I’m at the pump more…”) into a precise answer in seconds.

4. “What do I need to pay in the next 60 days?”
Insurance, road tax, service deadlines — projected forward, with the days you’ve got left. Catch renewals before they turn into a late fee.

5. “What did I spend the most on this year?”
The whole “where did the money actually go?” question, answered — a breakdown by category, biggest first, no spreadsheet required.

6. “When did I last drive to Florence?”
Your trip history becomes searchable by memory instead of by date. Perfect for “when was that client visit?” or “find my trips tagged work in May.”

7. “Compare this year with last year.”
Distance, cost, even CO₂ — any two periods side by side with the percentage change. Ask “how much less CO₂ did I produce this quarter versus last year?” and you get a real report, phrased like a question.

Tell it to log things (read-and-write)

8. “I just filled up — 35 litres at €1.728 a litre.”
You talk; it does the arithmetic (€60.48), files the refill, and tells you it’s your third of the month at €1.71/L average. This is the part that feels like magic the first time: no form, no keypad, no fuss.

9. “I paid road tax, €120 — remind me again next year.”
Logs the cost and sets the recurring deadline in the same breath. Same for “oil change done today, €89, next one in a year.”

10. “Add the note ‘client trip’ to yesterday’s drive to Florence.”
Reconstruct which drives were for work just by describing them — no scrolling to find the right trip.

Why it feels like magic

The trick isn’t any single answer. It’s three things happening at once:

Natural language. No forms, no exports, no query syntax. You ask the way you’d ask a person who knows your car.
Your real data. Not generic advice off the internet — your Juke, your fuel, your last trip to Florence.
It’s actually yours. Every other “AI meets your data” setup means handing your history to someone’s servers. Here the data stays on your phone, and only what you ask about is ever touched.

And it compounds when you chain requests: “compare my fuel this month versus last, and if it’s up, find my heaviest trips.” One sentence, a real piece of analysis — the sort of thing that used to mean exporting a CSV and squinting at it.

How to try it

You need Magica with API Mode switched on, a token, and any MCP-capable assistant (Claude, Cursor, Codex, Continue). It takes a few minutes — I wrote a step-by-step setup guide. And if you’re wondering how this stays private, here’s why your data never leaves your phone.

It’s early access, so the list of things you can ask keeps growing. But even today, talking to your car beats digging through it.
