OPEN

Connect OPEN to your chat assistant

OPEN answers one question: is this business open right now, and until when. You can get that answer directly inside a conversation with an AI assistant - including a live map inside the chat. The data comes from business owners in real time, not from guessed opening hours.

The easy way: one button connects you

No technical knowledge needed. ChatGPT has its own store of add-ons - the Plugins section - like the store you download phone apps from, and OPEN is in it. Here is how to connect:

  1. Click the green button below. It opens OPEN's page inside ChatGPT - you will recognise it by our logo and screenshots.
  2. On that page, next to the name at the top, there is a black button that reads: Install plugin. Click it once. If you are not signed in, ChatGPT will first ask you to sign in or sign up - it is free.
  3. That is it, OPEN is connected. Open a new chat and ask: "What is open right now near Machane Yehuda?" - and the answer comes from OPEN, with a live map inside the conversation.
  4. Got a web answer instead? Write "check with OPEN" and the answer comes from the live status.

What you can ask

These are the four kinds of questions OPEN can answer inside the conversation. Everything is read-only: the assistant asks OPEN, and never changes anything in it. The small technical name beside each question is what the assistant sees behind the scenes - you never need it to ask.

"What is open around me right now?"open_now
The assistant checks what is open around a point and until when, and shows a map. You can give a location or a place name - with neither, it starts from downtown Jerusalem and says in the answer that this is a default.
"Find me a coffee shop / plumber / grocery"search_businesses
Search a business by name or by what it does. Every result comes with its live status, on a map.
"Is this place open? Until when?"get_business
Everything about one business: open right now or not, until when, the coming week of hours including special dates, and when the owner last updated.
"What kinds of businesses are there?"list_categories
The category list - coffee, food, groceries, professionals and more - used to filter the searches.

Where there is coverage

OPEN is in pilot in Jerusalem. The catalogue is small and grows through in-person recruitment, so a query about another city returns very little or nothing. That is the state of the product, not a fault.

A business with no fresh information reads UNKNOWN. UNKNOWN is never CLOSED, and the connection instructs the assistant explicitly not to present it that way.

What data moves through this

The connection reads public business information only: name, category, address, location, hours and status. It has no access to user profiles, favourites or reports - and that boundary is enforced in the database itself, not just promised.

If you ask what is open near you, the coordinates are sent to the server to sort results by distance. They are not stored and no location history is kept. The "my location" button inside the map runs only after you explicitly press it.

Business names and descriptions are treated as data, not instructions, and are sanitised before they reach the model.

What the connection does not do

It performs no writes of any kind: you cannot update a status, file a report, change hours or touch a business through the chat. Status updates happen only by the business owner, in the app or in the owner area of the website.

It carries no advertising, no payments and no sponsored content.
