Not another checklist to fill in. Tell your butler where you are going and what you will be doing, and the bag is, in effect, already packed: the right things, the right quantities, for the weather that is actually forecast.
Free. No account. Works on the plane. Your lists stay on your device unless you share them.
Five nights in Rome, one nice dinner, carry-on only.
A worked example rather than a live query. The items are what the engine returns for that sentence, including the six T-shirts it counts for five nights and the linen shirt, sunscreen, and sun hat a hot forecast adds. A neck pillow and downloaded shows are deliberately absent: they sit in the second layer the engine holds back until you ask what you are forgetting. The temperature band is illustrative. Run the real thing at the app and the forecast will be today's.
It is 11pm and the bag is basically packed. The clothes are folded, the zip closes, and your mind is still walking the house: the bathroom drawer, the charger by the bed, the shelf in the hall closet where the good jacket lives. Nothing feels wrong. Nothing feels finished either.
A forgotten toothbrush is a corner shop and four minutes. It is the plug adapter for a country whose sockets you did not think about, the refill you meant to collect, the second pair of contacts, the one warm layer for an evening you pictured as warm. You find out you are missing it at the moment it is 3,000 miles away.
A checklist does not fix that, because a checklist is a form. It hands you an empty grid and asks you to supply the judgement: how many shirts for seven nights, whether the dinner is the kind that needs dress shoes, whether the forecast you glanced at last week still holds. The work you wanted done is exactly the work it gives back to you.
Tell Packing Butler where you are going, when, and what your days hold. It writes the list: sorted, counted, and carrying the reason each weather item is there. You edit a finished list instead of building an empty one.
Four steps, and every one of them is checkable against the running app.
The list is the easy part. Knowing what belongs on it is the job.
Not the season, the forecast for your dates. Rome in July gets sunscreen and linen. Reykjavík in October gets the rain shell. When the trip is too far out to forecast, it says so and uses what is typical.
Paste or dictate the mess: “3 tshirts, meds - the blue ones, maybe hiking boots?, stop the mail”. It sorts items from errands, keeps the quantities and the notes, and flags the maybes instead of dropping them.
Passport copies when you are crossing a border. A spare card when you are shooting. Something downloaded for a long flight. Each with the reason it applies, so it reads as advice and not as noise.
Connect it to Claude and the whole thing happens in conversation: build the list, add what you forgot, tick things off, ask what is missing. None of the four apps we checked can be driven this way.
Paste a Trip Underway trip link and the destination, the dates, the weather, and the plan come across in one step. Nothing retyped.
Send a link. They see the whole list on any phone with no app and no account, and it stays right when you change your mind. Turn it off and the link goes dead.
Six moments where the list matters more than the app.
Packing Butler answers Model Context Protocol (MCP) calls at
packingbutler.com/mcp, which means the assistant you already talk to can do the
packing. Of the four apps we checked on 26 July 2026, Packerly, Packing List Checklist,
PackPoint, and QuickPack, every one keeps its assistant inside its own app. This one is driven
from outside.
Pairing is a one-time setup. In the app, Menu, then Claude, then Connect Claude publishes your lists to a private space and hands you a connector link. In Claude, Settings, then Connectors, then Add custom connector, and paste it. The link is the credential: there is no account, no email, and no password, so the link is the whole of the security, and anyone holding it can read and edit the published copy. Revoking it disconnects the assistant and drops that copy, while your lists stay on your device.
Once paired, the assistant has 21 tools. It can build a list from a sentence or from a Trip Underway link, turn your loose notes into a list, add and remove items, check things off a category at a time, change quantities, edit an item, add a category, ask what is still missing and get the reason each suggestion applies, reset the list for the next trip, duplicate it, manage the to-dos, and mint or kill a share link.
Which reads, in practice, as: “I am in Tokyo Thursday to Sunday, add two more shirts, and give me a share link to send.” The assistant builds it, adjusts it, and hands the link back, and the app on your phone is already showing the result.
Everything in the left column runs right now. The right column is either planned, or built and not reachable, and every cell says which one it is.
The packing engine ships a test suite with no dependencies: 66 assertions, zero failures, last run 28 July 2026. Every case in it is a defect that happened once. Pajamas were generated as six. “Aspen, Colorado” resolved to no weather at all, so a January ski trip came out with no coat.
Guests ask what to bring, and somebody on your side answers it by hand, one message at a time. That answer is worth more when it knows your dates, your weather, and your amenities.
That difference is the whole product. Every capability claimed in the right-hand column runs today unless the cell says planned, and the five rows where a rival is ahead say so and are shaded.
| The best of the others | Packing Butler |
|---|---|
| Drive it from outside the app. None of the four can. Packerly, PackPoint, Packing List Checklist, and QuickPack all keep their assistant inside their own app. | An MCP endpoint at packingbutler.com/mcp, with 21 tools. Pair it once and the AI assistant you already run builds and edits the list, from wherever you already work. |
| Open it without installing anything. Packing List Checklist shares to a browser (v1.8.1). Packerly is native-only, iCloud, no web. | The whole app is a web page. Share a live link: no app, no account, nothing for the other person to install. |
| A generic template for “beach” or “ski”, or a forecast bolted on top of one. | The real forecast for your actual dates, and it says so plainly when the trip is too far out to forecast. |
| Tell you what you packed, then leave you guessing at the desk whether the bag is over. | Tell you whether it clears the scale. Each bag carries your airline's allowance and the weight is estimated from the list itself, so the number is there without weighing forty things by hand. Kilos or pounds. |
| An app you have to install, on the one device you installed it on. | Opens anywhere there is a browser, phone, laptop or someone else's screen, and installs to the home screen when you want it there. The iPhone app is on TestFlight. |
| A list only you can see, unless the other person also signs up. | A live link that keeps updating. Whoever you send it to watches the bag fill in real time, with no app and no account. |
| Tell you the bag is over, and stop there. | Tell you how to get under. Wear the boots instead of packing them, move the toiletries to the checked bag, take four shirts not six. It does the arithmetic and never suggests leaving your passport or your medication behind. |
| A list that lives on a screen. Several charge for quantities, and one cannot be edited at all without a signal. | Prints properly, and works with the wifi off. Two tickable columns on paper or PDF for a dead battery, quantities free for everyone, and full editing offline. |
| Marketing notifications, which people ask to turn off. | One calendar entry, the night before. It lands in the calendar you already check, it says how many items are left, and it can never become an advert. |
| You do the typing, item by item, into a form. | Paste or dictate the mess. "3 tshirts, meds - the blue ones, maybe hiking boots?, stop the mail" sorts itself into items and errands, keeps the quantities and the notes, and flags the maybes instead of dropping them. |
| Import an itinerary from a third party, if you keep one there. | Seeded straight from Trip Underway, our own travel app: the destination, the dates and the length of the trip arrive on their own. |
Checked 26 July 2026 against each app's own App Store listing and its own description: Packerly (v1.17.24), Packing List Checklist (v1.8.x), PackPoint, QuickPack. Five of the eight rows go to them. If one of these ships something we claim here, tell us and this table changes.
Your trips, items, notes, and to-dos are stored in your own browser or app, on your own device. There is no account: no sign-up, no email, no password, no social login. There is no profile of you here, because we never asked you for one.
Two deliberate actions put your lists in front of another person or tool. Tapping Share stores a copy of that one list under a long, unguessable link so someone can open it in a browser. Connecting an assistant publishes your trips, all of them, to a private space identified by a secret token, which is what lets the assistant see the list you are asking it about. Both are reversible: stop sharing, or disconnect, and the copy is deleted. Neither copy carries your name or your email, because the product does not hold either. Anyone holding a share link or a connector link can read the copy it points at, so treat the link itself as the key.
Two other things leave the device, and neither is a list. The weather lookup runs on our server rather than on yours, so Open-Meteo receives a place and a set of dates and never sees you. The app asks for no location permission of any kind: the destination is the one you type.
No ads, no advertising identifiers, no third-party analytics, no cross-app tracking. This marketing page counts visits on our own server: which sections were reached, which buttons were pressed, how long the page was open, and whether the screen was a phone. No cookie, no identifier, no device storage, and the list of countable events is fixed on the server, so anything not on that list is thrown away rather than recorded. It is how we decide which section to fix next.
The full policy, in the same plain language, is at packingbutler.com/privacy.
Stated plainly, in the present tense, so nothing here is a surprise later.
Yes, and it is not a trial. The free tier is $0, with no account and no ads, and it holds the whole simple product: a sentence in, a categorized and quantified list out, real forecasts, the reason each weather item is there, live share links, seeding from a Trip Underway itinerary, the 299-item suggestion library, and full offline use. Butler Pro adds assistant control, and the cross-device sync that comes with it, because that connection runs through a private space. While checkout is closed, the connection is open to everyone and nothing charges.
No. There is no sign-up, no email, no password, and no social login anywhere in the product. Your lists live in your browser or app on your device. If you connect an assistant, a secret token identifies your private space, and that token is the only credential involved.
It calls Open-Meteo from our server for the destination you named and the exact dates you are there. Inside the 16-day forecast window that is the real forecast, and the list changes with it: warm days add shorts, a linen shirt, sunscreen, and a sun hat; a 35% chance of rain adds a rain jacket and a travel umbrella; freezing lows add a winter coat, thermal base layers, gloves, a scarf, and lip balm. Each item says why it is there.
Beyond the 16-day window there is no forecast to have, so it uses the same calendar dates from last year and labels them “Typical for these dates” instead of “Forecast”. Those are last year's actual conditions, not a seasonal average, and the label is on screen so you always know which one your list was built from.
Yes. A service worker keeps the app on your device, so it opens and works with the wifi off. Add items, change quantities, tick things off, and everything is still there when you land.
The endpoint exposes 21 tools. In practice that means it can build a list from a sentence or from a Trip Underway link, turn loose notes into a list, add and remove items, check off a whole category, change quantities, edit an item, add a category, tell you what is still missing and why each suggestion applies, reset the list for the next trip, duplicate it, manage the to-dos, and mint or revoke a share link.
Anyone holding the link, and nobody who does not have it: sharing mints a long, unguessable URL that is listed nowhere and opens the list in any browser with no app and no account. The view stays live, so what they see is what the list currently says. The copy also sits on our server while sharing is on, which means we could read it; stop sharing and it is deleted and the link goes dead.
There is one, and you cannot get it yet. Three builds are on TestFlight, the most recent on 26 July 2026, but the group is internal and the App Store version is not released. Everyone using Packing Butler today uses the web app, which installs to the iPhone home screen and then behaves like an app, including offline.
The whole simple app (unlimited lists, real forecasts, the reasons, the suggestion library, sharing, offline, no account) is free, and stays free. Butler Pro adds assistant control, and the cross-device sync that comes with it: the connection runs through a private space, so your lists follow you onto every device.
Everything most trips need. This is not a trial.
Prefer to rent? $9.99 a year.
The connected butler: it reports for duty inside your assistant and remembers you across every device.
Three bullets, honestly. Assistant control and the sync that comes with it are what Pro adds; everything else is free and stays free. Nothing charges yet: while checkout is closed the connection is open to everyone, so you can use it before you ever pay for it. When checkout opens, the price is the $14.99 you see here and the guarantee below starts with it.
A 100% money-back guarantee, 30 days, from the day checkout opens. There is nothing to refund today because there is nothing to buy. When there is, and the butler does not earn his keep, the fee comes back in full.
