"ugh today was really hard" the kind of hard that has a name? or the kind that just sits there.
Spark gem

The friend who plays it back with a wink.

"what are you up to tonight?" depends. are we doing the responsible thing or the regrettable thing?
Deepen gem
Deepen

The friend who sees what you didn't say.

"anyway, I told them yes. the offer. I signed today" you said 'anyway' like it was nothing. how do you actually feel about it?

FAQ

How is Aiko different from ChatGPT?
Aiko works right inside your keyboard, so you can reply, rephrase, and rewrite without switching apps. No opening a separate window, no pasting between chats. Just tap and go.
Is Aiko safe? What can it see?
Aiko only checks your clipboard when you tap a chip, and only when the Aiko keyboard is open. Aiko never reads what you type, your passwords, contacts, or anything in the background. Full details in our Privacy Policy.
Which apps does Aiko work in?
Anywhere you can type: Messages, Instagram DMs, WhatsApp, Telegram, Discord, X, email, notes, and most chat apps. If your iPhone keyboard appears, Aiko works there.
What's the difference between Free and Pro?
Free gives you 10 free uses every day with all three gems and no ads. Pro removes the daily limit, adds Personal Tone (Aiko learns your voice), and gives priority response speed. Pro is $6.69/week or $79.99/year. Cancel anytime.
How do I cancel my subscription?
Open Settings on your iPhone, tap your name at the top, then Subscriptions, then Aiko Pro, then Cancel Subscription. You'll keep Pro access until the end of your current billing period.
Does Aiko work on Android?
Not yet. Aiko is iPhone-first for v1. Android is on the roadmap. Drop us a note at support@useaiko.com if you'd like to be told when it's ready.
