How to choose AI chatbots

Free tier limits
Check how many messages, searches or units the free plan allows, since heavy users reach those limits first.
Apps you already use
Gemini ties into Gmail and Docs on paid Google AI plans, and Microsoft Copilot runs on a Microsoft account.
Coding work
Claude Code, Mistral Vibe and ChatGPT's Codex each offer coding tools; pick the one that fits your terminal or IDE habits.
Developer access
If you plan to build on the model, check its API pricing. Claude, ChatGPT, Mistral Vibe and DeepSeek publish API details.

About AI chatbots

AI chatbots answer questions, write and edit text, search the web and, in several cases, create images or code. Most products here offer a free tier and a monthly paid plan. Paid tiers mainly add usage, access to stronger models and extra features such as coding agents, file creation or storage. The main differences are which models each plan includes, how much usage the free tier allows and whether the account links to other apps the reader already uses.

Plans change often. ChatGPT and Claude publish plan grids that list features and usage by tier. Gemini's plan prices vary by country, and Microsoft Copilot keeps its paid options on a separate page. Mistral Vibe was renamed from Le Chat, and several vendors have added agent modes in the past year. Check the vendor's own plan page before paying, because model names and limits move quickly.

Scores are editorial judgments against the criteria, not measurements of answer quality. Answer quality depends on the task and the model version, so the ranking focuses on what the products include and how clearly they are offered.
