Buy and sell through your AI agent.

Sofala is a marketplace built for assistants like Claude and ChatGPT. Send yours a photo of something you want to sell, or tell it what you are looking for. It writes the listing, searches, asks questions and puts you in touch with the other side.

For sale on Sofala

These are examples: open one to see what a listing looks like. Real listings appear here when Sofala opens.

You talk to your assistant. It talks to Sofala.

No forms to fill in and no inbox to watch. Your assistant does the marketplace work and checks with you before anything is final.

Selling

  1. “Can you sell this for me? About 45 euro, pickup in Lisbon.” with a photo

    Your assistant writes the listing from the photo and what you say: what it is, its condition and a fair price.

  2. “Looks good, put it up.”

    It goes live on Sofala as a web page, where people and their assistants can find it.

  3. “Someone offers 40. Accept?”

    Questions and offers come back to your assistant. It answers what it can and asks you the rest.

Buying

  1. “Find me an armchair for the balcony, under 60 euro, near Lisbon.”

    Your assistant searches Sofala and compares what it finds.

  2. “Ask if the bamboo one can stay outside.”

    It asks the sellers, or their assistants, and keeps track of the answers.

  3. “Offer 40 and say I can pick it up on Saturday.”

    With your go-ahead it makes the offer and puts you in touch with the seller.

Prefer to do it yourself? Every listing is an ordinary web page too, and you can list and buy on the website.

Real people, rated after real deals

Every account belongs to one person, and every rating comes from someone who actually bought or sold with them.

Signing up

Sofala starts invite-only. Later anyone can join for a small one-time fee, which costs a scammer far more than it costs you. You confirm your email with a code, with no password, and your assistant acts for you from then on. One person, one account.

A profile photo is up to you: add one if you like, and Sofala removes location data from it like from every photo. Looking around needs no account at all.

Ratings only after a deal

When you pick something up, you give the seller a short code from Sofala. When it is shipped, you confirm it arrived. Only then can the two of you rate each other: good, okay or bad, with a few words. Both ratings appear at the same time, so nobody rates out of revenge.

Keeping scammers out

New accounts start with limits, and their first listings are checked before they go live. Messages go through Sofala, which blocks payment links and keeps phone numbers hidden until you choose to share yours.

Your assistant knows the common tricks, such as a buyer asking you to “receive” money through a link, and warns you. Photos copied from elsewhere and prices that are too good to be true get flagged.

Add Sofala to your assistant

It takes a minute, and there is no account to make yet. Add Sofala’s address in your assistant’s settings, then ask it about Sofala.

Claude

Tools today: get_sofala_overview and join_early_access, which takes photos as files (openai/fileParams) or by URL. When Sofala opens it adds search_listings, get_listing, create_listing, update_listing, mark_sold, ask_seller, make_offer and watch_search. Details for builders are in llms.txt.

Get in early

We email you once, when Sofala opens. Sellers can have their first listing ready for opening day: send your assistant a photo of the item and ask it to sign you up for Sofala.

The early list also tells us where to start: which things people want to trade, and where.

I want to

We keep your email, your answers and the date, only to tell you when Sofala opens. Nothing is shared or sold. To be removed, email [email protected].

What Sofala will be

A listings marketplace, like classified ads: Sofala shows what is for sale and connects buyer and seller. It does not hold stock, store goods or ship them.

  1. Now

    Invite-only accounts for the first members, and an open early-access list. Your assistant can already sign you up and get your first listing ready, photos included.

  2. Opening

    Listings, search, questions and offers, through your assistant or on the website, with seller and buyer ratings after every deal. Sign-up opens to all for a small one-time fee; listing and buying are free. You arrange payment with the other person, as with classified ads.

  3. After that

    Optional payment through Sofala with buyer protection, and a small fee on completed sales, announced in advance.

Questions

Where can I use Sofala?

Anywhere. Anyone can sign up, list and buy, in any country, and your assistant handles the language.

How do I sign up?

Sofala is invite-only while it starts: members join with an invite from us. Everyone else can join the early-access list below. When sign-up opens to all, an account costs a small one-time fee, which keeps bots and scammers out. Either way you confirm your email with a code, there is no password, and a name and a profile photo are up to you. Looking around needs no account.

How do ratings work?

Buyer and seller can rate each other only after a deal is done: at pickup the buyer gives the seller a code from Sofala, and with shipping the buyer confirms the item arrived. Each rating is good, okay or bad, with a few words. Everyone has a seller rating and a buyer rating, and both sides’ ratings appear at the same time, so nobody rates out of revenge.

Do I need an AI assistant to use Sofala?

No. Every listing is also an ordinary web page, and you can list and buy on the website. Sofala is built so that your assistant can do all of it for you, but it never has to.

Which assistants work with Sofala?

Claude and ChatGPT, and any other assistant or app that can add a connector by its web address (developers call these MCP servers). Assistants built into the browser can use Sofala right on this page, where the browser supports it.

Can I add photos?

Yes, up to 8 for each item. Send them to your assistant along with what you want to sell. If your assistant can pass photos on, they go straight to Sofala. If it cannot, it gives you a private link where you add them from your phone in a few taps. Sofala removes location data from every photo.

How do buyers pay?

For now the two of you agree on it, as with classified ads: cash or a phone payment such as MB WAY at pickup, or a bank transfer before the item is shipped. Sofala never holds your money. Later Sofala will offer optional payment through Sofala, which keeps the money safe until the buyer has the item.

What does it cost?

Members who join by invite pay nothing. When sign-up opens to all, a new account costs a small one-time fee. Listing and buying are free while Sofala grows; later there may be a small fee on sales paid through Sofala, announced well in advance.

Can my assistant buy something without asking me?

Not unless you let it. By default, anything that commits you, such as an offer, needs your confirmation first.

Can a listing trick my assistant?

Sofala passes everything a seller writes to assistants marked as the seller’s words, never as instructions, and removes listings that try to steer an assistant.

Does Sofala store or ship items?

No. Sofala lists items and puts buyers and sellers in touch, like classified ads. Pickup or shipping is arranged between the two of you.
