Best AI Chatbot (2026): 7 Picks, Free Plans Compared

ChatGPT is the chatbot most people compare everything else against. OpenAI's pricing page describes a Free plan with text chats and limits on items such as image creation, voice chats and deep research. Plus is $20 per month and, per OpenAI's help center, is billed monthly only.

Above Plus, OpenAI sells Pro in tiers listed at $100, $200 and $500 per month. One help article said new Pro $200 sign-ups were paused in September 2026 and a newer one said they were available again with a lower allowance for new subscriptions, so availability may keep shifting. Check the current price on chatgpt.com/pricing before you subscribe.

For a first chatbot it is hard to go wrong, because the feature range is wide and help articles are plentiful.

Skip it if you want annual billing on a mid-priced plan or a tool built mainly around long-document reading.

Claude is the pick for people who spend their day with long text. Anthropic's pricing page describes Free for everyday questions with no fixed message count, so what you get depends on conversation length, the model and the features you use. Pro is listed at $20 per month, or $17 per month billed annually, and gives at least five times the per-session usage of Free.

Paid plans use a session limit that resets every five hours and a weekly limit, and usage on web, desktop, mobile and Claude Code draws from one pool. Max comes in two tiers, Max 5x at $100 per month and Max 20x at $200 per month. Anthropic also notes that it may apply other limits to keep access fair, so the exact allowance shows under Settings, then Usage.

Skip it if you want predictable fixed message counts, because limits depend on how you use it.

Gemini makes most sense when your mail, documents and files already sit in Google. Google's subscriptions page lists the AI Pro plan at $19.99 per month in the US with usage limits four times higher than Free, and the Google One benefits page lists 5 TB of storage across Gmail, Drive and Photos as part of the plan.

Above that, Ultra tiers start at $99.99 per month for five times the Pro limits. Google also offers eligible US college students aged 18 and over a free year of AI Pro, after which it renews at $19.99 per month unless you cancel. Prices differ by country, and the UK page shows a different figure.

The free app is a fair way to try it before you pay.

Skip it if you do not use Google services, because the storage and app links are a large part of the value.

Copilot is Microsoft's chatbot, and the free app is the main reason to include it. Microsoft's support pages describe a limited free version, subject to capacity and limits, with extras such as chat history, image creation, longer conversations and voice once you sign in with a personal account.

The paid route has changed. Microsoft says it will no longer sell Copilot Pro and points subscribers to Microsoft 365 Premium, which its page lists at $19.99 per month in the US for one to six people, with exclusive features such as Researcher and Analyst. Microsoft offers a one-month trial for its Personal, Family and Premium subscriptions. Storage figures differed across Microsoft pages, so we are not printing one.

Skip it if you do not use Windows or Microsoft 365, since the paid value is tied to that suite.

Perplexity works more like a search engine that writes an answer, which suits research where you want to check where a claim came from. The help center says Free users get practically unlimited basic searches and a limit of 3 Pro Searches per day, and that Free users cannot choose an advanced model manually.

Pro is listed at $20 per month or $200 per year on the homepage and unlocks Pro Search, Projects, file uploads, image generation and higher limits. The pricing page also lists a separate Max tier. Older pages describe different Pro Search limits, so treat the 3 per day figure as the help center's current statement and check it before you rely on it.

Skip it if you mainly want creative writing or long back-and-forth conversation rather than sourced answers.

Magai is a wrapper that puts chat models from several labs, including ChatGPT, Claude, Gemini, Grok, DeepSeek, Llama and Perplexity, behind one subscription. Magai says it calls each provider's own API rather than offering cheaper copies, and that you can change models in the middle of a chat and keep the context.

Magai's pricing page lists Standard at $20 per month, Pro at $40 and Ultra at $200, with every model and tool in all three and higher tiers adding usage, scheduled task runs and priority support. A 30-day money-back guarantee applies. Those are vendor claims on a promotional site, and model counts differ between its pages.

Skip it if one chatbot already covers your needs, since a single free plan costs nothing.

Monica is built around the browser. Its extension adds a sidebar on any page, a toolbar that appears when you highlight text, and a keyboard shortcut, Ctrl+M or Cmd+M, that opens the chat. Monica says it can summarize YouTube videos and pages, help draft emails and offers over 80 templates for marketing copy.

The pricing page lists Free, Pro and Max tiers, and the free tier has daily limits. Monica's pages name different models depending on when they were written, and its prices appear alongside promotional discounts, so we are not printing a figure. Check the current price on monica.im.

Skip it if you rarely use a browser for your AI work or want a clear list of models before you pay.
