Best AI chat apps for Android in 2026

You are probably reading this on a phone. Desktop reviews can miss problems that matter on a phone. An app that is excellent in a browser tab with a keyboard can be close to unusable one handed on a bus, so it is worth testing the app on your own phone.

So what follows is a checking order rather than a ranking. Seven steps, from working out what you want on a phone to having your existing conversations open on it. If you already have a shortlist from a ranked piece like our own best AI chat app roundup, run it through these steps instead of taking the ranking on trust.

Step 1. Start with what you do on a phone, not at a desk

Write down three things, honestly. Skip what you imagine doing with AI and record three things you actually did in the last week with a phone in your hand.

For most people the list comes out something like asking a quick question while queueing, or photographing something confusing and asking what it means. Notice that neither involves typing a long prompt.

That list decides everything below it. If photographing things is on it, image input matters more than model count. If dictating is on it, voice matters more than either, and voice access varies enormously between apps and between plans, so check it before you assume it is included.

Step 2. Check whether it is a real Android app

This step eliminates more candidates than any other. A surprising number of tools in this category are a website with an app icon in front of it, and a few skip Android altogether. AllChat, for one, ships on iPhone and web only. OpenRouter has no Android app at all, because it is built for developers wiring up their own software.

Three quick tests, in about ninety seconds each:

Search the Play Store for the exact product name and check the developer field matches the company, not a reseller.
Open the app and press the Android back gesture from a chat. A real app goes back a screen. A wrapped web view often exits to the home screen or does nothing.
Scroll a long answer fast. Wrapped web views stutter and lose scroll position in a way native lists do not.

Warning: an app being on the Play Store proves nothing on its own. Several listings in this category are the same web page in a shell, published by a company that never wrote a line of Android code. The back gesture test catches almost all of them.

Step 3. Find out what the free plan gives you on Android specifically

This is the step people skip, and the one that causes the "I thought this was free" moment three days in. Free tiers are not always identical across platforms, so check the app rather than the website.

Here is ours, stated plainly so you can compare like for like. On the free plan in our Android app you get 21 of our models within that plan's message allowance, plus file uploads at one image or PDF per message, up to 10MB, three uploads a day. Web search and image generation are Pro features in the Android app, and tapping either one tells you so rather than failing quietly. Voice input and voice calls are Pro as well. Paid plans are Pro at $20.99 a month or $199.99 a year, and Pro+ at $34.99 a month or $349.99 a year, broken down in full in our pricing section.

Whatever app you are testing, find the equivalent three numbers before you commit: how many models the free plan reaches, what happens when you attach a photo, and which buttons are decorative until you pay.

Step 4. Look at the model list, then look at how you change it

Model count is the number every app puts on its store listing, and on its own it tells you very little. What matters on a phone is the switch.

Open the model picker. Count the taps from a live conversation to a different model answering the same question. If it is more than three, you will never do it, and a large roster becomes decoration. Then check whether switching keeps the conversation or starts a new one. Losing the thread every time you change model defeats the point of having more than one.

For reference, our app carries 60 models from 18 providers, 47 of which accept an image, and switching happens inside the conversation so the history carries across.

Shortcut: if you cannot face comparing rosters, test one question. Ask each candidate app something with a genuinely contested answer, then try to get a second model to answer the same thing without retyping. The app that makes that easy is the one you want.

Step 5. The unglamorous things you will live with

These never appear in reviews.

Signal. No chat app in this category runs the big models on your handset, so all of them need a connection. What differs is the behaviour when it drops. A good app waits a few seconds before declaring you offline, shows a banner, and keeps your typed message. A bad one throws an error and eats the draft. Test it in a lift.

Backgrounding. Start a long answer, switch to another app for thirty seconds, come back. The answer should still be there and still be arriving. Ours resumes the stream from the server when you return.

Notifications and sharing. Ours does not ping you when an answer finishes and does not accept content shared from other apps yet, though links to your own conversations open straight into it rather than bouncing to a browser. Check both on any app you are considering, because neither is a given.

Step 6. Install it and spend five minutes on setup

Once one candidate survives, set it up properly rather than leaving it on the home screen.

Sign in with the account you will still have in two years. Signing in with a different provider on your laptop later is how people end up with two accounts and two histories.
Set your default model to one you will use for ordinary questions, not the most impressive one on the list. You can switch up for the hard ones.
Turn on whatever the app calls memories or personal context and give it two or three lines about your work and how you like answers written.
Send one throwaway message and one photo, so you have seen both paths work before you need them.

Step 7. Move a conversation across

Last step, and the one that makes the switch stick. You do not need to move everything, and you should not try.

Pick the two or three conversations you actually return to. Open each in your old app on a laptop, copy the useful part, and paste it into a new chat with one line at the top saying what it is and where you left off. Then add the standing facts, the ones you keep retyping, as memories rather than chat messages, so they apply everywhere instead of living in one thread. Coming from another assistant, our import memory page walks through that part.

Then delete the other app for two weeks. Not permanently, just long enough to find out whether you miss it. Most people do not, and the ones who do learn something more useful than any ranking would have told them.
