Letterboxd Movie Assistant is a free Chrome extension developed by ludovicodigital. It falls under the category of Browsers and is specifically listed in the Add-ons & Tools subcategory.

This extension adds a convenient icon in the address bar when you visit IMDb or Rotten Tomatoes film pages. By clicking on this icon, a new tab will open, taking you directly to the equivalent film page on Letterboxd.

It is important to note that this extension is not developed by the official Letterboxd team. Instead, it is created by a passionate fan of the site. The developer has recently fixed a bug with Rotten Tomatoes, ensuring that the extension now works seamlessly with IMDb. However, due to Rotten Tomatoes removing their public API, the extension no longer functions with Rotten Tomatoes.

With Letterboxd Movie Assistant, you can easily access Letterboxd film pages from IMDb, enhancing your film browsing experience.
