Best Poe Alternatives in 2026: What to Do Before the Knowledge Base Shuts Down

I left Poe roughly a year ago over the memory problem. Here’s why the May 25 deadline matters, and the alternatives I’d actually recommend. Generated by ChatGPT Poe is shutting down the Knowledge Base. The email was sent last week. The gist is that on May 25, 2026, every file ever uploaded to a KB gets permanently deleted, and bots that depended on one are now just prompts with no documents behind them. The official line is that “context windows are bigger now, so you don’t really need this anymore”. I’ll be honest. When I read that, I laughed. Not because it’s funny.
