It's for anyone who wants a clean place to ask questions and get fast, useful answers without choosing a model or configuring anything. If you can text a friend, you can use it. It costs $5 a month.

Who should not use Plainly?

Technical users who want API access, model choice, image or video generation, or memory across chats should use something built for that. Plainly deliberately has none of those. It is a simple chat window, and that is the whole product.

Does Plainly have API access?

No. There is no API key and nothing to integrate. Plainly is an app for asking questions, not a platform for building on. If you need an API, a developer platform is the right choice.

Can I choose which AI model Plainly uses?

No. Plainly picks the model for you and keeps the choice current, so you never have to think about it. The team is technical and maintains that default as the best options change.

What does Plainly cost?

$5 a month for unlimited chat. Cancel any time.

Is Plainly right for me? Who it fits

Plainly fits if you want one clean window, separate chats and $5 a month. Not if you need API access, model choice, images or cross-chat memory.

Is Plainly right for me?

Yes, if you want one clean window where you ask a question and get a fast, useful answer for $5 a month. No, if you want API access, your own model choice, image or video generation, or memory that carries across chats.

Who Plainly is exactly right for

Plainly is for the person who just needs an app to ask questions to. You open it, type what you want help with (an email, a plan, a decision, an explanation) and you read the answer. There's nothing to set up and nothing to learn first.

That describes more people than it sounds like. You can use AI every day, for real work, and still have no interest in managing it. Plainly is for the ones who want the answer, not the console. It's the cheap ChatGPT alternative for someone who never wanted a project in the first place.

If that describes someone you know rather than you, the handoff is its own small piece of work: what AI to recommend to a non-technical friend is the script.

Who should not subscribe

Four groups should keep their money.

People who want API access. Plainly has no API. There is no key to generate and nothing to build against. If you're wiring AI into a script, a product, or a pipeline, this is the wrong tool.

People who want to choose their own model. Plainly chooses. You never see a picker or a setting for it, and you never pick. If choosing the model is part of the value for you, that control lives elsewhere, and you should go get it.

People who need image or video generation. Plainly doesn't make pictures or clips. It writes and answers, and that is the whole of it.

People who need projects or memory across chats. Chats stay separate, and nothing carries from one to the next. There's no project to organise and no workspace waiting for you when you return.

If you're in one of those four groups, you already know it, and you already have a tool that does it better.

Why those exclusions are the design

A maintained default beats a menu.

The team behind Plainly is technical. They follow the frontier and the best-value models, and they move the default as the ground shifts under it. That is work you don't have to do, and it's why a question comes back strong without you specifying anything.

Every option Plainly exposes hands a decision back to the person who just wanted an answer. Every feature it carries is latency, surface area, and one more thing that can break. The things Plainly doesn't build are what keep it quick and simple.

That trade has a cost of its own, covered in what's the catch with cheap AI.

What you actually get


What it is	One clean AI window with separate chats
What it costs	$5 a month
What it does	Asks and answers, fast
What it doesn't do	API access, model choice, image or video, cross-chat memory

One window. You ask; you read. Separate chats, so one conversation never leaks into the next. Fast answers from a default that is maintained for you. $5 a month, and you can cancel any time.

If you're still weighing the price against the alternatives, two pieces do that arithmetic plainly: why there is no free plan, and whether $5 is good enough.

The direct answer

Plainly isn't the most capable AI you can buy, and it doesn't pretend to be. It serves a maintained default instead of letting you reach for the strongest model on demand, and it keeps no memory of you between chats. If your work sits at the very top end (the hardest coding, specialist research, anything where the first answer has to be the best one), a premium subscription earns its price and Plainly will feel like a ceiling. ChatGPT Plus is $20 a month, and Claude Pro starts at about the same (OpenAI and Anthropic pricing pages, as-of 2026-08-29). Most questions never go near that ceiling. Yours might.
