poe2filter.com - A PoE 2 custom loot filter generation website

Maybe I'm dumb and/or blind...
How can I create multiple filters? The sync function always overwrites the same filter in my POE2 account. I want to use different filters for different chars.

I can reassure you you're not dumbn or blind :p Indeed, the tool currently always syncs to the same filter, poe2filter. In the next update (probably for coming weekend), I plan to add full multi-filter support.

For now, you can download multiple .filter files. Depending on which character you're playing, you can import that character's .filter file, and then sync that one to the game, always overriding the previous one. Just keep the .filter files up-to-date.
