A dated, sourced comparison. We're the maker of one of these two, so check the parts that matter to you.
Replika is the most established name in this category, and its 2026 rebuild is the most credible marketing we found anywhere in it: fewer superlatives, warmer photography, a real memory demo instead of an adjective. If you're weighing Replika against Teylo, this page tries to make that comparison without softening what Replika does well or overstating what Teylo does.
You want to see something. Replika's hero shows an illustrated companion figure over the chat bubbles, and the whole visual identity leans on that image. Teylo shows no avatar, for anyone, ever, by design. If a visual presence is part of what you want from this, Replika has one.
You want a romantic option. One of Replika's four rotating homepage lines is "The AI friend to fall in love," so romance is offered outright if that's what you're looking for. Teylo is platonic only, and that isn't a setting you can change.
You want a longer track record. Replika says it built "the world's first AI companion" ten years ago and rebuilt the product in 2026, and its own homepage counter currently reads 42,160,934 users worldwide. Teylo launched more recently. There's no long public history here yet to point to.
You want a friend, not a partner. Teylo's four are platonic and stay that way. Nothing escalates, nothing is unlocked by paying, and none of them will ever perform being in love with you.
You do not want another app. They live in your Messages and your call log, beside everyone else you know. There is nothing to open, and nothing that shows you a streak for coming back.
You want to be remembered without being farmed. They keep what you told them because a friend would, and Teylo does not sell it, train on it for anyone else, or use it to work out what would keep you online longer.
Same numbers as everywhere else on the site.
