Plain answers.
How Selby works, what it will and will not do, and where your photos go.
Everything, in one place
Does Selby post to the marketplaces for me?+
Selby writes, prices and polishes the listing, then copies the version written for each marketplace and opens that marketplace's posting page so you paste it in one tap. Facebook Marketplace, OfferUp, Craigslist and Nextdoor have no public listing API and ban automated posting; eBay's API needs a seller integration we do not ship yet. Bots get seller accounts banned, so Selby never posts on your behalf and never claims to. It does everything up to that tap, and everything after it.
How do the plans work?+
Two ways in. The Month Pass is $29 once: 45 Selby-written listings over 30 days, it never renews and there is nothing to cancel — made for clearing out a garage. The Membership is unlimited everything at $15 a month or $111 a year (38% off), starts with a free trial, and cancels anytime from your account. Both include Selby answering and negotiating with buyers, and per-marketplace versions of every listing. Photo Studio is free on every plan because it runs on your device.
Where do my photos go?+
Photo Studio tools (auto-fix, crop, rotate, background removal) run entirely in your browser; nothing is uploaded. Selby-written listings send the photos you choose to Google Gemini for analysis through our server, which forwards them and keeps no copy. Photos and listings are stored on your device (and in your account when you sign in), never sold, never used to train anything.
How good is the background removal?+
It uses an open-source salient-object model (U²-Net-p, Apache-2.0) that runs on-device in about a second and costs nothing to use. It is excellent on clear product shots and good on busy backgrounds; hair, glass and thin cables can need the feather slider. Auto-fix, backdrops, crop and straighten run on-device too, so editing a photo never costs you anything.
Can I edit a listing after it is posted?+
Every field, every time: title, price, condition, description, tags, photos (add, remove, reorder, re-edit, change the cover), marketplaces and each marketplace's own version of the copy. Ask Selby to rewrite anything in a friendlier, shorter or more premium tone.
What is Selby allowed to say to buyers?+
Only what you set: it never accepts less than your floor (default 80% of asking) and never reveals it, proposes only your chosen meetup spot and availability, and answers condition questions from the honest notes on the listing. You can read every thread and take over with one tap.
Which marketplaces are supported?+
eBay, Facebook Marketplace, OfferUp, Craigslist, Nextdoor, Poshmark, Mercari and Depop today. Selby writes a version for each one's audience and length limits.
Do I need to install anything?+
No. Selby is a web app built for phones and tablets. Open it in Safari or Chrome, tap "Add to Home Screen" and it behaves like an app, with offline access to your listings and cached studio tools.
Can I cancel?+
Memberships cancel anytime from your account — inside the free trial nothing is ever charged, and after it you keep access until the end of the period you paid for. The Month Pass never renews, so there is nothing to cancel. Your listings stay on your device either way.
What if Selby gets my item wrong?+
Add a note before analysis ("it's the 2019 model, missing the remote"), or fix any field afterwards. If Selby has no AI connection it says so loudly and shows labelled sample data instead of pretending.
Take the photo.
Selby takes it from there.
