What's here.
What's next.

Open a page and you are in a room with everyone else on it. Chat, reactions, presence, plus the real Reddit, Trustpilot, X, Bluesky and Discord takes stacked in the header.

One agent per page. It reads what you are looking at, finds a better price across retailers, checks the seller, and answers back in the room.

Every purchase you make anywhere on the web files itself into one place. Point the camera at a card, a slab or a sealed box and it comes back as the exact one, priced per grade, so you can see what the whole shelf is worth today. Only a browser can assemble this, because only a browser sees every store you check out on.

Sign a spending budget with your passkey and your agent checks out on the store's own site. That signed budget is the only thing that can mint a single use card scoped to one merchant, so your real card is never exposed and never leaves the vault.

Highlight any phrase on any page and attach a note, flag, source or price check. Clip a region, or a moment out of a YouTube video or an X post. Comment in text or record your voice. Visible to everyone else running Basement.

A live 0 to 100 confidence score. It cross checks stock across eight retailers, weighs the signal from the room, and flags fakes.

Real prices across retailers, watches that catch a restock or a drop the moment it lands, and standing orders that buy when your condition is met.

Set what you meant to spend, shelve the thing you almost bought, and watch the money you kept add up. Your agent can pick a shelved item back up when it hits your price.

A portable reputation. Your annotations, accurate calls and cited sources become a credential that follows you across every site.

Good annotations earn signal. Accurate calls level you up. Bad faith notes cost you. Ten floors, one contribution loop.

First annotation in a dormant room? You get the Key. Custom badge art, rarity rolls, and a share card of your own.

Optional subscriptions that give your shopper a wallet and more room to work. Baseling priority, deeper context, unlimited pinned rooms, no ads ever. Depth is still earned, never bought.

The collector build of the Collection: every grade priced, the real sales behind each number, and what the whole shelf is worth over time. Trading cards, LEGO and games are the first catalogs.

Tell your agent what you want and how far you will travel, and it watches Facebook Marketplace and OfferUp for it. When a match lands, you hear about it.

Checkout beyond the paid tiers, on a trust ramp: a small capped spend for a new shopper, more authority as their record grows.

Text your agent for anything you want and it goes hunting: Facebook Marketplace, OfferUp, eBay and retail at once, priced against what the item is actually worth, with the listing and the seller checked before you go.

Your agent stops being a buyer only. It sells for you out of the Collection it already keeps, because it knows what you own, what it is worth today and where it moves fastest, and it can match you with someone in Basement to trade with instead of a stranger and a listing fee.

Because Basement can prove you own the thing, a product room becomes a review layer only real buyers post in. Merchant funded discounts will redeem against that reputation, so honest signal pays the shopper instead of the store.

A public API for annotations, rooms, wallets and scores, plus an SDK so teams can plug in without rebuilding the stack.
