ChatGPT Alternatives: Claude, Gemini, Mistral, Perplexity, Copilot

What you are comparing against: ChatGPT at $0, $8, $20 and $100

OpenAI's pricing documentation lists ChatGPT Free at $0, Go at $8 a month, Plus at $20 a month and Pro from $100 a month. The Pro tier has three steps: $100, $200 and $500. On Plus, OpenAI gives message estimates per 5-hour window that vary by model, for example 15 to 160 for GPT-6.1 Sol and 350 to 3,000 for GPT-6 Luna, and weekly limits may also apply.

OpenAI's main ChatGPT pricing page and help center returned an access error when we tried to read them on 2026-11-01. The ChatGPT numbers here come from its Codex and ChatGPT docs page, so this guide does not compare ChatGPT's file, voice or search limits. Check those on chatgpt.com before you switch.

Claude: the closest swap for long documents

Claude Pro is $20 billed monthly or $17 a month on an annual plan, and Anthropic lists Opus, Sonnet and Haiku in it. The Free plan costs $0 but has no Opus and caps projects at five.

The upload limits are the reason to pick Claude for reading work. A single chat accepts up to 20 files, each up to 500MB, and PDFs up to 1000 pages. A PDF of 100 pages or fewer is read for both text and visuals. A PDF of 101 to 1000 pages is read as text only. Anything over 1000 pages is rejected with an error.

Claude's context window reaches 1M tokens on paid plans for the newest models, and 500K or 200K for others. Paid usage runs on a session limit that resets five hours after your first message, plus a weekly limit.

Gemini: the pick if your life is already in Google

Gemini Free needs only a Google account and includes Deep Research, Gemini Live, Canvas, Gems and image generation. Google AI Plus is EUR 4.99 a month with 2x Free usage and 400 GB of storage. Google AI Pro is EUR 21.99 with 4x Free usage, 5 TB of storage and Gemini inside Gmail and Docs. The prices we read were shown in euros on Google's Estonian page; check your own country's page for local pricing.

The context window grows with the plan: 32k tokens with no plan, 128k on AI Plus and 1 million on AI Pro. Google's help page says limits refresh every 5 hours until a weekly limit is reached, and that they can change without notice.

Mistral Le Chat: the cheapest paid chat on this list

Mistral's Pro plan is $14.99 a month before taxes, which is $5.01 less than ChatGPT Plus. Mistral describes the gains as multiples of the free plan: up to 6x messages, up to 5x web searches and up to 40x image generation. Document libraries reach 15GB on Pro, and project folders go up to 1,000.

The free tier lists no price and no numbers, only that messages and web searches are limited. Mistral's page also lists the Pro student price as $5.99 a month in its FAQ while the plan card shows $14.99, so confirm at checkout before relying on the student rate.

Perplexity and Copilot: search first, chat second

Perplexity's Pro page says its Best mode runs without quota limits and gives 10x as many citations per answer. It lists models from several makers, including Sonar, GPT-5.2, Claude Sonnet 4.6 and Gemini 3.1 Pro. No price appears on that page, so we do not quote one.

Microsoft Copilot has a free tier with a Microsoft account, and Word, Excel and PowerPoint are free on the web. The page we read lists no price. It does say Deep Research is now called Researcher and Tasks is now called Cowork, which helps if an older guide uses the old names.

A worked example: a $20 plan swapped for two cheaper ones

Say you pay for ChatGPT Plus at $20 a month, which is $240 a year. You mostly chat and search, and open a long PDF twice a month. Mistral Pro at $14.99 covers the chat and search: 12 months cost $179.88, a saving of $60.12 a year.

If you then keep the long-PDF work on the free Claude plan, the total stays $179.88, though the free plan has its own limits per 5-hour and weekly window. If you instead move to Claude Pro on its annual price of $17 a month, the year costs $204, which is $36 less than Plus.

Mistakes that make a switch feel worse than it is

Comparing a free plan with a paid plan is the most common one. Claude Free has no Opus, and Gemini Free uses the Flash-Lite model, so a weak answer there says little about the paid plan.

Another is reading a multiplier as a count. Gemini's 4x on AI Pro is four times the standard limit, which Google never states as a number of prompts. The same goes for Mistral's 6x. Test with your real tasks for one week before cancelling anything.

Last, check where your chat history lives. Moving to another assistant does not carry over past conversations.

Who should stay and who should move

Stay on ChatGPT if you rely on features we could not check, such as its voice mode or custom tools, or if the Go plan at $8 already covers you. Move to Claude if you work with long files, to Gemini if you use Gmail and Docs all day, and to Mistral if price is the main reason.

If you are staring at a plan page and cannot tell which row applies to you, Crade can read the page on your screen and point to the limit that matters.
