Claude-Instant-100k is available on Poe.com (but only usable as a paying subscriber). Claude-plus-100k isn't up yet but I'm guessing that's a matter of time.
Should keep you logged in for longer and easier to log back in.
Also, there is no way to search the history. The sidebar only shows titles, not contents. I have to click each one to see what’s inside. I can’t scroll much because it loads more only when I click. I ended up exporting the conversations and converting JSON to txt.
Another issue: editing a long past message makes it scroll up and hide the cursor if the message is longer than one screen. I have to type in another editor and then copy&paste the whole text. The typing experience is poor.
