How to choose an AI chat app

Judge an AI chat app on six things: whether it remembers context, whether you can reach more than one model, what happens to the output after the chat, what it can connect to, what it costs at your real usage, and whether you can leave with your data. Feature lists are long; these six decide whether it survives contact with your week.

Choosing an assistant by benchmark score is like choosing a notebook by paper weight. It is a real property, and it is not the thing that decides whether you use it.

1. Does it remember, and can you correct it?

Spend a day explaining your context, then start a fresh conversation and see what survives. Then try to fix something it got wrong. If correcting memory is impossible or all-or-nothing, the feature is a demo.

2. Can you reach more than one model?

Different models are better at different things, and the leader changes every few months. A product that lets you route — fast for trivia, heavy for reasoning — ages better than one tied to a single family, and it means a bad week for one vendor is not a bad week for you.

3. What happens to the output?

Most replies are disposable. Some are not: a plan, a spec, a comparison table you will edit for a week. If the app only produces chat bubbles, you will spend your time copying into another tool. Look for artifacts — documents and visualizations that stay editable beside the conversation.

4. What can it connect to?

An assistant that cannot read your calendar or your notes is answering from general knowledge. Integrations over an open protocol such as MCP mean the catalog can grow without the vendor shipping every connector itself.

5. What does it cost at your actual usage?

Compare the shape of the pricing, not the sticker. Message caps suit light use; usage pools measured in dollars suit bursty work where one long session costs more than a week of short ones. Swirl's paid plans are $5, $12, and $30 per month with optional top-ups, and the free tier is five messages, which is enough to test the first four criteria.

6. Can you leave?

Export your conversations, delete your memory, cancel without a phone call. A product that makes leaving hard is telling you what it thinks of your leverage. This is also the cheapest thing to check and the one people skip.

Run those six checks in an afternoon with two candidates. The winner is rarely the one with the longest feature page — it is the one you stop thinking about by Friday.

Questions

Should I pay for an AI chat app or use a free one?

Start free and pay when a specific limit gets in your way — a message cap, a missing model, or memory you want to keep. Paying before you have a habit is the most common way people waste a subscription.

Does a higher price mean a better model?

Not directly. Price usually buys usage volume and access to heavier models. The same model can sit behind a cheap plan and an expensive one; what changes is how much of it you can spend.

How many messages do I need to evaluate an app?

About five, if you spend them well: one to explain your context, one to test recall in a new thread, one hard question, one file upload, and one task that produces something you would keep.
