okay so for the past few months i’ve basically been stress testing almost every ai chatbot i could get my hands on. paid, free, open source, whatever. i had one goal find something that doesn’t fall apart in long conversations, doesn’t forget its own character, and doesn’t kill the immersion halfway through.
the biggest pattern i’ve noticed is this: the first 5 to 10 messages are amazing. you’re like okay this is it. the replies are detailed, fluid, loyal to the lore. then around message 20 the classic ai amnesia kicks in. suddenly it forgets key details, responses shrink to two sentences, or it switches into that weird safe npc mode.
here’s my experience so far:
character ai: still one of the most fun and user friendly platforms. but once you throw complex or long lore at it, things start breaking. around 30 messages in, even if it remembers its name, it kind of forgets its motivation. and the filters don’t help.
claude 3.5 sonnet paid: context wise and intelligence wise, it’s insane. it can pull up a detail from 50 messages ago like it’s nothing. but when it comes to roleplay it feels tense. one small thing and you’re getting the as an ai… speech again. immersion gone.
chatbotapp and chatbotapp ai: these have been lowkey some of my recent favorites. the multiple bot support is nice, and what surprised me most is that the replies don’t immediately turn robotic in longer sessions. context retention felt more stable than a lot of bigger popular apps, at least in my tests.
kindroid and nomi: they’ve really nailed the companion vibe. long term memory is actually impressive. but if you try to build a hardcore world with politics, war, technical rp stuff, it slowly drifts back into romance mode. suddenly it’s all emotional bonding and the original plot fades out.
novelai kayra: if you lean into the writing side, the lorebook system is honestly kind of magical. but it doesn’t really feel like a chatbot. more like a co writer. interaction takes more effort.
chub ai venus and janitor ai: this side of things is more wild west energy. amazing character cards out there, but model quality can be all over the place. unless you plug in your own api, which can get expensive, consistency eventually drops.
polybuzz and candy ai: strong visual presentation, good for fast casual use. but if you’re trying to run a 40 to 50 message story arc with deep lore, they start to feel a bit shallow.
what i’m looking for is simple in theory:
a memory that doesn’t go wait which village were we in after 50 messages.
long, lore loyal, character specific responses.
no system meltdown when i introduce a plot twist or tweak the prompt mid conversation.
