Chai vs PolyBuzz: which phone chat app earns your money?

So far, a tie, and if you only compared feature lists you could stop reading here and pick either one.

The differences start with where you can chat. Chai is on record for iOS and Android only, with every plan sold as an App Store in-app purchase. PolyBuzz runs on the web, iOS and Android, and sells yearly plans through web checkout too.

If you like to chat on a laptop, PolyBuzz is the only one of the two that lets you.

The free start is vaguer than I'd like on both sides. Chai costs nothing to install, sells extras in the app, and has no official free message limit on record; secondary sources describe the limit as fluctuating rather than stable. PolyBuzz describes chat as "free, unlimited, and private" while naming no daily cap, and its free plan covers text chat on the Standard model with ads, plus two voice plays and a single image to begin with.

For me, PolyBuzz is the more honest free offer, simply because it tells you what the free plan contains.

Then there is money. Chai Premium costs $13.99 a month, PolyBuzz Poly Standard Monthly costs $9.90. That $4.09 gap every month is the single fact I would weigh most, because on paper Chai does not give you more for it: no voice calls, images only on paid plans, and no official feature list for Premium at all.

My take: PolyBuzz is the easier recommendation for most readers, and Chai suits someone who wants a plain phone app and nothing else. The two apps side by side, right below, lay out the features. My PolyBuzz review with every plan and its catch goes deeper into the paid tiers.

PolyBuzz is said to lose details in long scenes too, but its Premium tier lists stronger memory chat models, and Ultimate adds a model called Permanent Memory. If memory matters to you, PolyBuzz at least gives you a paid way to improve it. Chai does not publish one.

My advice either way: keep each scene brief and remind the character of the important facts every so often.

Both apps keep a soft content policy, so neither is the pick for full adult content. That makes either one a reasonable choice for flirty chat that stays tame. On images, I'd give PolyBuzz the round, since it gives you a free first try.

Chai publishes no cancel steps of its own, so the store you paid through is where to look. My Chai AI review with its plans and refund rule has the rest.

There is no group chat and no voice calls, so think of Chai as a text app for one-on-one chat, and judge it on that basis.

The free start is where Chai frustrates me. Downloading is free and extras are sold in the app, but the free message limit isn't officially set out, and secondary sources report that the limit fluctuates. I prefer apps that tell you the number, because a moving limit makes it hard to judge whether the free plan is enough.

The paid ladder has one plan I like and one I would avoid. Premium at $13.99 a month, or $134.99 a year at $11.25 a month, is the sensible way in. Secondary sources say it brings unlimited messages and no ads, but Chai does not publish its own list, so treat that as likely rather than promised.

Ultra is the one I'd skip in its weekly form: $19.99 a week works out to $86.62 a month, while Ultra Monthly is $29.99. Paying by the week means nearly triple the cost for an identical tier.

The refund note on file is the standard Apple EULA warranty clause, not a Chai refund policy, so I would not count on getting money back. Start with the free app, and if you do subscribe, go month by month at first. The yearly Premium plan only makes sense once a few months have shown you that Chai sticks.

If you want to see Chai against other apps too, my collection of app-versus-app comparisons has more pairings.

• Starting free: Free tier
• Lowest price: $11.25 monthly (Premium Subscription (Annual))
• Allowed: unconfirmed
• Runs on: ios, android

The free plan is the part I like best. Its FAQ calls chat free and unlimited without naming a daily cap, and the plan gives text chat on the Standard model with ads, two voice plays and one image as a starter. Images after that are gated by coins, so the free plan is a chat plan first. For a free start, that is still more than Chai spells out.

The paid tiers climb in a clear way. Poly Standard Monthly is $9.90, and the yearly web plan at $99 comes to $8.25 a month. Poly Premium Monthly at $19.90 adds stronger memory chat models, unlimited voice listening, no ads and priority chat. Poly Ultimate at $29.90 adds more models, including Permanent Memory.

My pick is Standard yearly on the web if you already know you like it, and Premium only if memory really matters to you.

The weekly plan is the one I'd avoid: $4.99 a week becomes $21.62 a month, more than twice the monthly Standard price. The refund rules are strict too: a finished purchase isn't refunded without due reason, and a plan keeps renewing unless you cancel by the final day of the period.

For where these facts come from, my page on how I gather app facts from official pages explains the sources.

• Starting free: Free tier
• Lowest price: $8.25 monthly (Poly Standard Year (web))
• Allowed: unconfirmed
• Runs on: web, ios, android

If you chat lightly, both cost you nothing to start. PolyBuzz is the clearer free deal: text chat on the Standard model with ads and no published daily ceiling. Chai is free to download, yet with no official free limit on record I can't say how many messages you'd get.

If you chat most nights and want to pay, the cheapest sensible plan on this page is PolyBuzz Standard at $9.90 a month, or $99 a year on the web at $8.25 a month. Chai Premium is $13.99 a month, or $134.99 a year at $11.25 a month. On yearly plans, that is $3.00 a month in PolyBuzz's favour, and on monthly plans $4.09.

If you want the top tier, the two are close on monthly price: Poly Ultimate at $29.90 against Chai Ultra Monthly at $29.99. Poly Premium sits in between at $19.90 a month, adding stronger memory chat models and no ads. The trap is the weekly billing.

Chai Ultra Weekly at $19.99 comes to $86.62 a month, and Poly Standard Weekly at $4.99 comes to $21.62. My advice is blunt: never pick a weekly plan on either app unless you truly want only one week. A single month on the monthly plan is the cheaper way to try a paid tier, on both apps.

If what you really want is pictures and a character with more memory, neither app is built for that, and my Candy AI vs OurDream AI comparison for image-first apps is the better next read.

With Chai, the catch is uncertainty. The free limit is not officially published and is said to fluctuate, Premium has no official feature list, and no cancel steps or statement name are on record. None of that makes Chai a bad app, but it means you are buying on trust. If you go ahead, pay monthly and note the renewal date yourself.

With PolyBuzz, the catch is memory and a strict refund rule. Long scenes can drift, and a completed purchase is not refunded without due reason. The weekly plan also looks cheap at $4.99 and is not. On the plus side, PolyBuzz spells out how to leave: on iOS through the Apple ID subscriptions screen, on Android through Google Play.

My ranking between those two catches is simple. Uncertainty bothers me more than a known limit, because you can plan around a limit you know about. That is one more reason I would start with PolyBuzz.

• It works in a browser, so you are not tied to one phone.
• The free plan says what it includes: chat with ads, two voice plays and one image.
• Its monthly Standard plan costs $4.09 less than Chai Premium.
• It offers a paid path to better memory, which Chai does not publish.
• Its yearly Standard plan on the web comes to $8.25 per month.

I would still tell that friend that Chai is not a mistake. If all you want is a quick character chat on your phone and you never touch a laptop, it does the basic job. Just keep away from its weekly Ultra plan, which costs $86.62 a month once you do the math.

If you want Ultra at all, the monthly plan at $29.99 is the only version I would consider.

And I would add one warning for both: memory is the weak spot, so do not expect either app to remember a long story. If you're after a companion with a good memory who can also speak to you, my Candy AI vs Nomi AI comparison for memory and voice covers two apps that put that first.
