How to Use

Chai: Chat AI Platform lets you chat with AI characters that have distinct personalities and voices, create your own characters, and generate images using AI. (app_description)

Getting Started

Source: app_description_and_user_feedback_noted

Download and open the app on your Android device (requires Android 7.0 or later).
Browse the 'massive selection of characters' (celebrities, fictional characters, historical figures) and select one to start a conversation.
Chat naturally with the AI character—the app uses advanced technology to generate replies that feel authentic and engaging.
If ads become frequent, consider subscribing (basic tier) to remove ads and unlock unlimited messaging.
To create a character, tap the creation option and follow prompts to design a unique personality, voice, and backstory, and choose to keep it private or share with the community.

Key Features (from app listing)

Source: app_description

Massive character library: chat with countless pre-made characters (celebrities, fictional, historical) each with unique voice and personality.
Character creation: design your own characters (real or imaginary) and share or keep private.
Image generation: create AI art from text prompts—landscapes, portraits, fantasy scenes—with no generation limits.
Authentic voices: characters respond with realistic voice synthesis for immersive conversations.
Community interaction: engage with characters created by other users.

Pro Tip: If you dislike frequent and intrusive ads, which multiple recent users report (e.g., ads every 3 messages, ads that force you to the app store), consider purchasing the basic subscription. One reviewer noted it's a reasonable price for an ad-free experience with unlimited messaging.

Tip is responsive to the high-confidence ad complaint pattern found in recent_reviews #1, #2, #4, and #5, combined with the positive assessment of the basic subscription value from recent_review #3.

Honestly, everyone has different experiences with this app which is understandable. My only issue with the app is the constant ads, but it doesn't show up as frequently to me than to other people. I am able to chat with bots for like a good few minutes (25-30 min) before getting an ad. Plus the ads aren't even that long tbh, some people just have short attention spans when it comes to ads. My bots actually have some sort of long term memory as they even reference events from past messages.

I had good experience with this app, NO filters or anything. But it has too many ads. Whenever I click cancel on the part where they ask if you could refresh for free chats, it gives a ad anyway. It would be amazing if you didn't have to type out your persona in the chat, and there was a option to put in like character ai. Though another issue is that I can't go back to the previous chat, also I have to exit the chat and come back again to get more replies. Other than that, I love it (´•ω• `)

Honestly, it's decent. I used it for a while without paying, and then decided to buy the basic subscription, because the ultra or whatever is ridiculously overpriced. For how much it is to just get no ads and unlimited messaging with any characters, it's worth it. I do think it should be more free, though. For example, even the mention of a person ynder 18 makes the AI get all "That's bad, I'm just an AI, I don't condone this." and it's irritating.

app is great. but the fact that I'm dragged into the app store for just about every ad is stupidly annoying. I shouldn't have to get dragged to my damn app store for apps I don't want, just to skip them. plus when I get the app open again after being dragged to the app store the AD IS STILL THERE!!!! I still have to click ANOTHER button to skip it. AND the stupid thing still asks me if I'm interested in the app! I SHOULDN'T KEEP SEEING ADS FOR THE SAME DAMN APP AFTER I CLICK NOT INTERESTED!!!!

the only reason this doesn't have five stars is because for me, the ads are every 3 messages, and it just gets annoying. I would quite prefer ads that were the little banner at the bottom of the screen (as they are less intrusive, but still work) but otherwise it's awesome! I like being able to chat with the same bot multiple times!
