tl;dr like the Facebook Marketplace autofill extensions, but for any listing form. It fills, you review and submit


Hello there, want to share something I created/still working on and something what can save you a lot of time in daily work routine.
Because there a lot of extensions for Facebook marketplace’s form, I got an idea to build a something that helps fill out forms on every website.


How its works:
  1. Add the car once in the web app (all necessary data like milage, color, whatever, and photos)
  2. Install the extension and connect to your account with inventory
  3. Open any listing form then pick the car from the extension and start filling by clicking once
  4. After it filled out, review data, fill skipped fields and submit
Its also imports a car from a listing you already have somewhere else (step 1). You can paste a link or raw text, ai extract all data and create the inventory listing.


What its doesent do:
  • It’s never guess. If there no data in listing, its leave field empty instead of picking whatever looks closest.
  • Its tells what is skipped, which field extension skip
  • It never submits. You should review and publish by yourself

I continuously testing and enhancing this tool, so there a lot of edge cases I guess but if you want to try it I’ll post the link in the comments, if admins approve this post. It’s free (adding inventory is a free on web app).


Ps. Attach short demo gif how it works on European marketplace form
Pss. Im not using ai to write this post

A developer shares a Chrome extension they built that auto-fills vehicle listing forms across any website, not just Facebook Marketplace. Users add car details and photos once in a web app, then the extension populates listing forms on any site with a single click. The thread introduces the tool as a time-saving alternative to the many Facebook-specific autofill extensions already on the market.
