One photo.
Every marketplace.
Zero effort.
Selby identifies what you’re selling, prices it from real sold comps, writes the listing, polishes the photos, and gets it ready for eBay, Facebook, OfferUp, Craigslist, Nextdoor, Poshmark, Mercari and Depop. Then it answers your buyers and haggles for your best price.
Free plan · No credit card · Runs in your phone’s browser, no app store
Six seconds from photo to priced, written, ready.
No forms, no templates, no guessing at prices. Selby reads your photos like an experienced reseller would, then does the paperwork for all eight marketplaces at once. Every word stays editable.
- Sees brand, model & flawsMultiple angles, one item, one honest condition report.
- Prices from real sold compsA range you can move inside, not one mystery number.
- Writes for each marketplaceSEO for eBay, neighborly for Nextdoor, casual for Depop.
- Keeps every field editableChange anything before, during, or after posting.
Five steps. You do one of them.
The order matters, so we number it. Selby is built around the moment you take the photo; everything after that is Selby’s job unless you want it back.
- 01
Snap it
Take up to six photos in the browser or pick them from your gallery. Selby reads all angles as one item, plus any note you add ("missing remote", "size 10.5").
your part - 02
Polish it
Photo Studio fixes exposure and color, straightens and crops, and removes the background right on your device. Or hand it to AI Studio for a re-lit, white-backdrop product shot.
- 03
Selby writes & prices
Brand, model, condition with visible flaws, an honest description, search tags, and a price backed by real sold comps with a low-high range you can move inside.
- 04
Post everywhere
One tap per marketplace copies the version written for that audience and opens its posting page. eBay SEO, neighborly Nextdoor, casual Depop, and five more.
- 05
Selby handles buyers
Answers questions, counters lowballs above your floor, proposes your meetup spot, books the pickup and reminds you. Take over any conversation with one tap.
Studio photos from a kitchen-table snapshot.
Listings with clean, bright, background-free photos sell faster and for more. Selby’s studio does the tedious part on your phone, in a second or two, with no credits to count. Every photo in a listing can be edited again later.
- Background removal
Runs on your device with an open-source model. Pick a white, gradient or transparent backdrop.
- Auto-fix
Levels, contrast, white balance and a touch of sharpening in one tap. Sliders when you want them.
- Crop & straighten
Square for Poshmark, 4:3 for eBay, 4:5 for Facebook. Straighten by a few degrees.
- Rotate & flip
Because phones lie about orientation and mirrors exist.
- AI Studio (Pro)
Re-shoots the item on a seamless white sweep with studio lighting, keeping every scratch honest.
- Up to 6 photos per listing
Reorder, set the cover, re-edit any of them after posting.
The lowball arrives at 11:40pm. Selby’s already replied.
You set the rules once: the lowest price you’ll take, where you meet, and when you’re free. Selby answers questions honestly, counters offers without ever revealing your floor, proposes your spot, books the pickup and reminds you both. Step in and take over any thread at any time.
- Negotiation floor
Default 80% of asking. Selby never goes under it and never says what it is.
- Your meetup spot
Public, well-lit, yours. Selby proposes it, never your address.
- Your availability
"Weekday evenings after 5" is all Selby needs to book a time.
- Reminders that show up
2 hours and 30 minutes before, plus one tap to add it to your calendar.
Listing generators write. Crosslisters copy. Selby sells.
Most tools stop when the text is written. The work that actually gets an item sold, the photos, the follow-ups, the haggling, the pickup, is still yours. Selby takes that too.

The questions everyone asks first.
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.
What does the Free plan really include?+
The whole listing flow on all eight marketplaces, Photo Studio with on-device background removal, the buyer inbox and pickup scheduling. Selby-written listings are hosted for 5 a month on Free, or unlimited when you add your own free Google AI key in Settings (no billing setup, about 1,500 requests a day). Pro adds unlimited hosted AI, AI Studio re-shoots and Selby the negotiator.
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, either straight from your device with your own key or through our server on hosted plans. 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 without a key?+
It uses an open-source salient-object model (U²-Net-p, Apache-2.0) that runs on-device in about a second. It is excellent on clear product shots and good on busy backgrounds; hair, glass and thin cables can need the feather slider. AI Studio on Pro re-shoots the item with a full image model for the toughest photos.
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.
Take the photo.
Selby takes it from there.
