AutoLister AI is a browser extension, a small program that adds functions to Chrome, plus a web app for phones. On a Vinted listing page the seller adds item photos, and the tool sends them to an OpenAI model that writes a title, a description and hashtags. A content script, the part of an extension that runs inside a web page, fills the result into the listing form, and the seller checks it and publishes. The founder, Sami, is a Dutch software engineer who builds small products alone; TrustMRR gives the founding date as 31 August 2025.

The money figures come from TrustMRR, a site that reads revenue directly from a founder's payment provider, here Stripe. On 6 November 2026 it showed MRR (monthly recurring revenue, the subscription income of one month) of US$376 from 48 active subscriptions, US$457 of revenue in the last 30 days and US$2,807 in total. Monthly revenue rose from US$33.15 in December 2025 to US$467 in September 2026, then was US$460 in October.

This is a very small business: US$376 a month is about US$4,512 a year. The page is here because the numbers are verified by the payment provider, the product is live and updated (version 1.4.37 on 5 November 2026), and the method, a cheap AI writer placed inside one marketplace's own page, can be copied by one engineer.

When did AutoLister AI launch, and how did it grow?

From the founding date to a flat level of about US$450 a month, in 14 months. Each entry carries its grade.

03

Why did AutoLister AI work?

Four causes, in the order they mattered. Each one is a reusable lesson.

01

Inside the seller's own page

The extension works on the Vinted listing form itself: photos go in, text comes out in the right fields, and the seller only reviews. A web app covers phones, and the home page offers an iPhone and iPad setup through the Orion browser.

02

A small price for a repeated task

Starter costs €3.99 a month for 75 listings, and one-time credit packs serve sellers who list rarely. The pricing page shows the cost per listing for each plan. The average subscription, about US$7.83 a month, shows that most buyers take the cheapest plans.

03

One marketplace, many languages

The site and the generated text come in many languages: the pricing page says 18 for listing text, and the site has pages in French, German, Dutch, Polish, Spanish, Italian and Portuguese. Guides such as a Vinted description template and a listing checklist sit on the same site.

04

Features that add a reason to pay

In October and November 2026 the founder added AI model photos, batch drafts for several items and rewriting of existing listings. No source yet shows whether they raised revenue: October was close to September.

How it was built

These details come from the company's privacy policy, terms, store listing and TrustMRR profile. They are grade C, except the payment provider, which TrustMRR confirms. [5, 4, 1]

  • A Chrome extension with a content script that reads the selected photos and fields on a Vinted item page and fills in the generated text.
  • A web app for phones and computers that keeps drafts in the browser; photos are uploaded only for the generation.
  • OpenAI prepares the listing text and creates the model photos.
  • Supabase handles sign-in by email link, email code or Google, and stores accounts, usage counters and saved models in an EU region. Resend sends the sign-in emails.
  • Stripe Checkout and the Stripe billing portal take payments. Cloudflare hosts the static pages and the edge functions.
  • A ChatGPT plugin moves a draft prepared in ChatGPT into the web app.

Who tried this before AutoLister AI, and why did they fail?

Four companies in our database of failed startups promised to make second-hand selling easier and closed. The values below are from that database and are not independently verified.

Died 2012 to 2021Burned US$150M

Tradesy

The promise

A peer-to-peer marketplace for pre-owned designer clothes and accessories.

Why it died

Could not stand apart from The RealReal and Poshmark, which grew faster and earned more trust.

Competition
Died 2012 to 2020Burned US$153M

Poshmark UK

The promise

Social selling of second-hand fashion in the United Kingdom.

Why it died

Depop and Vinted had stronger communities and mobile apps, and the service was not adapted to the local market.

Competition
Died 2013 to 2016Burned US$1.5M

Selltag

The promise

Easy listing and discovery of second-hand goods in a local community.

Why it died

Never reached enough buyers and sellers per area; Wallapop and Facebook Marketplace were bigger.

Competition
Died 2013 to 2017Burned US$22M

MoveLoot

The promise

Selling used furniture with pickup, storage and delivery handled for the seller.

Why it died

Warehouses and trucks cost more than the low resale margins could pay.

Unit Economics

The failed startups come from our database of 1,749 dead startups, retold here in our own words. Its entries are AI-assisted summaries of public sources, so these cards carry no evidence grade.

What changed

The four predecessors tried to be the marketplace, or to carry the goods, and needed millions of dollars to attract buyers and sellers at the same time. Each lost to a bigger marketplace or to its own logistics costs. AutoLister does not compete with Vinted: it is a small tool for Vinted's sellers, and Vinted brings the buyers.

What made this possible after 2023 is that a vision-language model can look at a photo of a jacket and write a usable title and description in seconds, so one engineer can sell the result for a few euros a month. The same fact is the risk: the business rests on Vinted's page layout and on OpenAI's prices, and Stripe data shows that revenue stopped growing after September 2026.

05

Can one person copy AutoLister AI now?

Yes, with a small ceiling so far.

One engineer built a working extension, a web app and subscriptions in about three months from the founding date to the first revenue. The verified result is about US$450 a month, so the copyable part is the method, not a living income.

Where it is still open: The same tool for other marketplaces with many small sellers, for example local classifieds, car listings or handmade goods, where the platform's own listing form has no good AI help.

  1. 1Pick one large marketplace whose sellers repeat a writing task for every item.
  2. 2Put the AI inside the marketplace's own listing page with a browser extension, and add a web app for phones.
  3. 3Charge a few euros a month with a clear allowance per listing, plus one-time credit packs.
  4. 4Write help pages that answer the sellers' own questions, in their languages.

What could go wrong for AutoLister AI?

The risks are the mirror image of the causes above.

Very small and no longer growing

Verified MRR is US$376, about US$4,512 a year. Monthly revenue grew from December 2025 to September 2026, then fell 1.5% in October, and the last 30 days were 5.5% below the 30 days before, according to TrustMRR on 6 November 2026.

Competition

Marketplace listing writers are a crowded field: this site already has ValorixAI, an Etsy listing generator, and PureZap, which replaces backgrounds of Vinted and Allegro photos with much smaller verified revenue. Vinted itself, or a general chat app, could add the same function.

Dependence on OpenAI and on Vinted

The privacy policy, updated 1 November 2026, says OpenAI prepares the listing text and creates the model photos, so OpenAI's prices and rules set the cost. The extension works on Vinted's pages; the site says it is "not affiliated with, endorsed by, or sponsored by Vinted", and a page change or a rule against such tools could stop it.

AI model photos of clothes

The "Your model" feature shows an item on a generated person. The site labels them "AI-generated examples" and says the photos "illustrate the item, not its actual fit"; buyers on Vinted may not see that label. The extension can also rewrite many existing listings at once, with the seller reviewing each change; it does not publish for the seller.

Unsourced claims on the site

The home page quotes one seller by first name and initial only ("Otília N., seller"), and the model-photo page shows "5 to 135 views. 0 to 33 favourites. Sold." without saying whose listings these are. Neither could be checked.

Country

TrustMRR gives the country as SK (Slovakia), while IndieMakerList and the Chrome Web Store trader address place the founder in the Netherlands. This page uses the Netherlands.
