AI personal assistant app: what a good one does and how to choose

A good AI personal assistant app takes the small jobs that clutter your head (a bill to note, a birthday to remember, a renewal to check, a memory to find) and does them when you ask in a plain sentence, then reminds you before anything is due. It should show you what it did, let you undo it, only see what you give it, and be clear about where your data goes. It suits busy adults who are fine at the big stuff but keep losing the small stuff: the MOT date, the insurance renewal, the name of that restaurant from last spring.

Most people searching for one don't want a clever chat. They want fewer things to hold in their head. That's the test worth applying to anything you try.

What to look for in an AI personal assistant app

Plenty of tools can hold a conversation. Far fewer are any use on a wet Tuesday when you've just remembered the car tax. Here's what separates the two.

1. It acts, not just answers. You should be able to say "add the water bill, it's monthly, due on the 14th" and have it saved properly, not get a paragraph about water bills back.
2. It shows its work. After every action you should see exactly what was added or changed, with a way to undo it. An AI that quietly edits your records is worse than none.
3. Reminders with lead time. A nudge on the day a renewal lands is too late to compare quotes. Look for reminders that arrive before the date, and a regular look ahead at what's coming.
4. Repeating things repeat. Monthly bills, yearly renewals and birthdays should roll forward on their own, without you re-entering them every time.
5. One place for everything. If dates live in one tool, documents in another and memories in a third, you'll still be the one joining the dots.
6. Plain English search. "When did I last get the boiler serviced" should find the answer without you remembering which folder it went in.
7. Quiet hours. Something that pings at 11pm about a dentist appointment next month will get muted within a week.
8. Honest about what it is. It should never pretend to be a person, and it should only see your own things, not trawl through everything on your phone.
9. Clear privacy and an exit. Before you start, you should know which AI companies process your data, where your account is hosted, whether anything is used to train AI models, and how to export or delete everything.

If a tool misses the last two, the rest doesn't matter much.

What it shouldn't do for you

It's worth being clear on the limits too. An AI that keeps your life admin in order is a memory and a nudge, not an adviser. It can remind you that the home insurance renews in three weeks; it shouldn't tell you which policy to buy. It can remind you about a prescription renewal; questions about the medicine itself belong with a GP or pharmacist. And for UK deadlines like the MOT, vehicle tax or a passport, the dates that count are the ones on your own documents, and the rules are the ones on GOV.UK. A good tool helps you act on those, it doesn't replace checking them.

Be wary of anything that wants access to your email, bank or calendar before it has done anything useful. Handing over the keys to everything is a big ask for a first date.

How to set one up in 20 minutes

This works with any tool, from an AI app to a notes app and a calendar. The point is to get the important dates in early, so the reminders start earning their keep straight away.

1. Minutes 1 to 3: check the privacy page. Read who processes your data and where it's kept. If you can't find a clear answer, stop here.
2. Minutes 3 to 5: set your quiet hours. Pick the hours you never want a nudge, usually overnight and maybe your evenings. Do this first so the tool never annoys you into ignoring it.
3. Minutes 5 to 10: add the five dates that hurt most when missed. For most people that's the MOT, vehicle tax, car insurance, home or contents insurance and the TV Licence. Take each date from the document itself, not from memory.
4. Minutes 10 to 13: add your regular bills. Rent or mortgage, council tax, energy, broadband and phone, each with how often it repeats.
5. Minutes 13 to 16: add birthdays and anniversaries. Start with the six people who would notice most if you forgot.
6. Minutes 16 to 18: add one document with an expiry date. A passport or driving licence is a good start. Set a reminder well ahead, and check the current processing times on GOV.UK before you apply.
7. Minutes 18 to 20: ask it a test question. Something like "what's coming up this month". If the answer is right and useful, you're set. If it's muddled, you've lost 20 minutes rather than a year of trust.

After that, add things as they arrive. A letter comes, you add it the same day, and it's gone from your head.

How mylife/ handles this

mylife/ keeps your memories and your life admin in one private place, with an AI mate called Slash that keeps it for you. You can ask Slash to add a bill, find a memory, log a spend, set a reminder, plan something with a friend or tell you what's coming up this week. It shows you what it did and lets you undo it. Slash only ever sees your own things, and it's honest that it's an AI.

Life admin sits in ledgers: bills, home, car, documents, health, insurance, subscriptions, warranties, travel and dates. You can add things yourself, tell Slash in a sentence, or photograph a letter or pick a PDF and Slash reads it into life admin, filling in the details for you to check before anything is saved. The server deletes the photo or PDF once it has been read. You get a nudge before anything is due, never during your quiet hours, and a morning note flags what's coming up.

Privacy in mylife/

Before Slash starts, the app shows exactly which AI companies are involved and what each one receives. Your account is hosted in the EU, in Paris. Slash runs on Anthropic's AI and OpenAI turns speech into words; both are in the US, and under their commercial terms neither uses your data to train its models. Nothing you keep in mylife/ is sold or used for ads, and you can export everything or delete your account whenever you like. There's more on how privacy works in mylife/, and you can try mylife/ free for 3 days.

Common mistakes when choosing one

• Picking on cleverness. The tool that writes the best poem isn't necessarily the one that remembers your boiler service. Judge it on the boring jobs.
• Starting with everything. Trying to load ten years of paperwork on day one is how people give up on day two. Start with the dates that cost you when missed.
• Trusting dates from memory. If you type "MOT's sometime in March", you'll get a reminder for sometime in March. Copy dates from the certificate or letter.
• Ignoring the reminder settings. Default reminders are often too close to the date. A nudge a few weeks ahead for renewals and documents gives you time to do something about it.
• Not checking the exit. If you can't export what you've added, you're stuck with that tool forever, or you lose the lot.
• Treating it as advice. It keeps track; you still decide. For money worries, MoneyHelper offers free, impartial help.

Frequently asked questions

What is an AI personal assistant app?

It's an app you talk or type to in plain English that does small practical jobs for you, such as adding a bill, setting a reminder or finding something you saved. The useful ones keep what you give them organised and remind you before dates arrive. They don't replace your own judgement on decisions.

Is it safe to use an AI personal assistant app with personal information?

It depends on the app, so check before you add anything sensitive. Look for a clear list of which AI companies process your data, where your account is hosted, whether your data is used to train AI models, and how to export and delete it. If an app can't answer those plainly, don't give it your personal details.

Can an AI personal assistant app remind me about my MOT and car tax?

Yes, if you add the dates. Take them from your MOT certificate and your vehicle tax reminder rather than guessing, and set the nudge a few weeks ahead. The DVLA also sends a reminder when vehicle tax is due, and you can check the current rules on GOV.UK.

Does an AI assistant need access to my email and bank?

No. Plenty of useful ones work entirely from what you add or tell them, which also means they only see what you choose to share. Wide access can save some typing, but it's a big privacy trade, so think about whether the convenience is worth it.

How long does it take to set one up?

About 20 minutes gets the important things in: quiet hours, your key renewal dates, regular bills, a handful of birthdays and one document with an expiry date. After that, it's a minute here and there as new letters and dates turn up.
