Is there a free ChatGPT alternative without ads?

Yes. Claude's free plan shows no ads (Anthropic pledged in February 2026 to keep Claude ad-free). DeepSeek's privacy policy says it does no targeted advertising, and Google says Gemini app chats aren't used to show you ads. DeepSeek and Gemini train on your chats unless you opt out; Claude asks at sign-up, with training on unless you switch it off.

Is Google AI Plus worth $4.99 a month?

If you already use Gmail, Drive and Google Photos, often yes. It costs $4.99 a month in the US and adds 400 GB of storage and double the free Gemini usage limits. You are limited to Google's models, and your chats feed model training while Keep Activity is on.

Which AI chat apps don't train on your conversations?

Most consumer AI apps train on your chats by default and offer an opt-out, including ChatGPT, Gemini, Copilot and Mistral's Vibe. Claude asks at sign-up, and its pricing page lists training as opt-out. Plainly never uses chats to train AI, at $5 a month, and business plans such as Claude Team exclude training by default.

What is the cheapest way to use several AI models in one app?

Poe's cheapest paid plan, $4.99 a month in its US App Store listing, gives one app with models from OpenAI, Anthropic, Google and others. Each model costs a different number of points per message, so the large models use up the allowance fastest.

Is Claude Pro cheaper than ChatGPT Plus?

Only on annual billing. Both cost $20 a month billed monthly, and Claude Pro drops to $17 a month when you pay $200 for a year up front. Claude Pro has usage limits that heavy users reach, while OpenAI lists everyday text chats on Plus as unlimited.

Best cheap ChatGPT alternatives in 2026, ranked

Eleven cheap ChatGPT alternatives ranked on price, ads and data: Google AI Plus at $4.99, Plainly at $5, Claude, DeepSeek, Copilot, Poe and more.

The best cheap ChatGPT alternatives in 2026

For everyday questions, the best cheap ChatGPT alternatives are Plainly ($5 a month, no ads, chats never used for training) and Google AI Plus ($4.99 a month). The best free options are ChatGPT's own free plan, Claude Free and DeepSeek. Eleven options are ranked below, with prices, ads and data policies checked on 11 October 2026. If price isn't the main thing, the wider ranking of the best AI apps covers the full-price plans too.

I built Plainly, and it ranks first here. The criterion behind the order is stated below, so you can apply it yourself and disagree.

What is a cheap ChatGPT alternative?

A cheap ChatGPT alternative is an AI chat app that handles everyday asking (writing an email, planning a week, explaining a letter, giving a second opinion) for free or for a flat few dollars a month, instead of ChatGPT Plus at $20. The good ones run models slightly off the frontier. Those models are smaller than the biggest in the world and still very capable, and everyday tasks rarely need more.

Four things separate a real one from a lookalike:

A flat monthly price you can read in one line, with no credits to watch.
A model capable enough that the answers hold up for ordinary work.
A clear deal on your data: who reads your chats and whether they train the next model.
No ads on a plan you pay for.

Running an AI query costs real money, because every answer is computed on hardware somebody paid for. Free plans are paid for some other way. Paying subscribers carry part of the cost, and your data usually carries the rest: it gets read and used to train future models. Companies don't necessarily sell it. My view is that you shouldn't rely on a free AI product for anything that matters, which is why the paid options in this list sit next to the free ones.

How this list is ranked

The criterion is value for everyday asking: what you pay, weighed against how capable the answers are, then against what you give up in ads and data. Features that everyday questions rarely need, such as image generation, voice and coding agents, count for little here.

I use AI heavily. I have used ChatGPT, Claude and Perplexity heavily, and I run my own everyday chat setup through OpenRouter. DeepSeek and Gemini I have used on their websites only, never their phone apps. The rest of the list is ranked on each provider's published prices and policies.

All checked 11 October 2026.

1. Plainly: $5 a month

Plainly is $5 a month for unlimited chat, and you can cancel any time in settings. New accounts can ask a limited amount free each month. Plainly runs one capable open-source model and switches when a better one comes out. You never pick. It searches the web when a question needs current information and links the sources it used, reads documents and photos you attach, and keeps working in long chats. There are no ads, and chats are never used to train AI.

The catch: no image or video generation, no voice mode, no memory across chats, and no phone app (it runs in the browser). The model is an efficient one, slightly off the frontier. In a writing test I ran on 2 September 2026, ChatGPT (on Go) and Plainly each scored 61 of 75; ChatGPT won two tasks, Plainly won two and one tied. The models weren't run in a randomized order. The full results are in the best AI for writing test.

Who it suits: someone who asks AI a lot of everyday questions and wants one flat price with nothing to manage.

2. Google AI Plus: $4.99 a month

Google AI Plus is one cent cheaper than Plainly. It doubles the free Gemini usage limits, gives more access to Gemini 3.1 Pro, and includes 400 GB of storage across Gmail, Drive and Photos that you can share with up to five family members (Google's Gemini and Google One plans pages, October 2026). Google says Gemini app chats are not used to show you ads.

The catch is data and choice. While Keep Activity is on, Google uses your chats to improve its services, including training its models, and a subset of chats is read by human reviewers (Gemini privacy hub, October 2026). You also get Google's models and nothing else. My answer when someone points out that it's cheaper than Plainly: "good, but you're tied to Google's models, and Google's models aren't currently state of the art."

Who it suits: someone already paying Google for storage, or who lives in Gmail and Docs. For them, AI Plus is the better buy.

3. ChatGPT Free: $0

ChatGPT's free plan is the baseline every alternative gets measured against. You get unlimited everyday text chats on GPT-6 Luna, limited image generation and limited deep research, per OpenAI's pricing page in October 2026. It's quick and smooth, and you can't complain about free.

The catch: ads may show, your chats train OpenAI's models unless you switch that off, and the default model holds about 27,000 tokens of conversation (roughly 12 pages). Past that, it starts losing what you said earlier.

Who it suits: anyone asking the odd question who doesn't mind ads.

4. Claude Free: $0

Claude's free plan includes web search, file creation, memory across conversations and the same apps on web, desktop and phone (claude.com/pricing, October 2026). Anthropic pledged in February 2026 to keep Claude ad-free. On Free, Pro and Max, you're asked at sign-up whether your chats can be used to train Claude. Anthropic's pricing page lists training on those plans as opt-out, and you can change it later in the privacy settings (Anthropic, August 2025; claude.com/pricing, October 2026).

The catch is usage. Free has the smallest allowance of Claude's plans, and Anthropic sells Pro on "more usage". I have used Claude heavily and like it, and I pay for it today. In my view Claude Pro at $20 stays off a cheap list because it gives little usage for the money: fine for light use, too little for someone asking all day. I was on Pro for a long time, and my friends and I always ran out. Around January 2026 I moved to Max 5× at $100 a month, and I still hit its limit. More on that in Claude Pro's usage limits.

Who it suits: a light user who wants an ad-free free plan with strong writing.

5. DeepSeek: $0

DeepSeek's chat is free on the web and in its phone app, with no subscription, and its privacy policy says it does no targeted advertising. DeepSeek makes some of the best-known open-source models, and many cheap apps build on models like them.

The catch: DeepSeek's privacy policy (updated 10 February 2026) says it collects, processes and stores your data in the People's Republic of China and uses it to train its models. You can opt out by emailing privacy@deepseek.com. I have used DeepSeek on its website only. The comparison with ChatGPT's app is in DeepSeek vs ChatGPT.

Who it suits: someone who wants a strong free model and is comfortable with where the data goes.

6. Microsoft Copilot: free, or $19.99 inside Microsoft 365 Premium

Copilot is free in Windows, Edge and its own app. Paid Copilot use now comes with Microsoft 365, and the plan with the most of it is Microsoft 365 Premium at $19.99 a month. Microsoft's consumer plan page (October 2026) lists no standalone Copilot Pro.

The catch: Copilot shows ads. Microsoft's privacy statement says Copilot uses prompts "to provide and improve services, including relevant advertising", and its Copilot FAQ says signed-in users' conversations train Microsoft's models unless they opt out.

I've used Copilot only a little, for basic questions. Who it suits: someone on Windows who wants an assistant already on the machine.

7. Vibe (formerly Le Chat), by Mistral: free, or $14.99 a month

Mistral renamed Le Chat to Vibe on 28 May 2026; accounts carried over and it still lives at chat.mistral.ai. The free plan gives limited messages and web searches and basic image generation. Pro is $14.99 a month, or $5.99 for verified students (Mistral's pricing page, October 2026).

The catch: Mistral's help center says chats are used to train its models by default, with an opt-out. At $14.99, Pro costs about three times Google AI Plus.

Who it suits: someone who prefers a European company.

8. ChatGPT Go: $8 a month

Go keeps Free's models and doubles the default model's memory within a chat to about 40 pages, adds memory of past chats and scheduled tasks, and lifts image generation (OpenAI's pricing page, October 2026). OpenAI's page says "This plan may include ads."

I have Go, included with a Revolut subscription. On the default Instant model I hit the forgetting problem: partway through a task, the chat lost things I had told it earlier in the same conversation. My view is that Go is a bad tier: ads, a short Instant memory, and the smaller model. The full breakdown is in is ChatGPT Go worth it.

Who it suits: someone who wants ChatGPT's features and won't pay $20.

9. Poe: from $4.99 a month

Poe, from Quora, puts models from OpenAI, Anthropic, Google and others in one app. The cheapest paid plan costs $4.99 a month in Poe's US App Store listing, where it's called Basic. Poe's own pricing page wouldn't load for this check.

The catch is the meter. Each model costs a different number of points per message, so a frontier model uses up the day's points far faster than a small one. Poe's privacy policy says model providers may use your chats "to provide and generally improve their services."

Who it suits: someone curious to try many models side by side.

10. Perplexity Free: $0 (Pro $20 a month)

Perplexity answers with sources listed under each reply. Free is $0, Pro is $20 a month and Education Pro is $10 for verified students. Perplexity launched sponsored follow-up questions in 2024 and has since wound its ad program down, per the Financial Times.

I had a free year of Pro through my phone company and used it heavily for a few weeks, then not at all for ten months. I was glad I hadn't paid. My impression, which is anecdotal, was that answers felt weaker than the same models used directly, and I don't like the interface. If this list held only my own picks, Perplexity is the popular app I would leave off.

Who it suits: someone whose questions are mostly look-ups where the sources matter.

11. Meta AI: $0

Meta AI is free inside WhatsApp, Instagram, Facebook, Messenger and its own app. For anyone already in WhatsApp all day, it's the shortest path to an answer.

The catch: since 16 December 2025, Meta uses your chats with Meta AI to tailor the content and ads you see across its apps, in most regions. Meta's announcement points to general ad controls and describes no switch for this specific use.

I've used Meta AI inside Instagram, which is where most people will meet it. Who it suits: someone who wants a quick answer without leaving a chat app.

For technical people: bring your own key

If you're comfortable with API keys, you can pay per message instead of per month. OpenRouter lists 458 models behind one key (11 October 2026), and a desktop app sends your questions to whichever you choose. I run Hermes this way. From 16 August to 15 September 2026, the two models I chat with every day came to US$18.90 for the month. My whole OpenRouter bill was about $49, and part of that was image generation. This route means managing keys, credits and model choices, which most people don't want.

When to pay $20 or more instead

My rule of thumb: if you use AI a little, the $20 Claude plan is good. If you use it a lot, the $5 Plainly plan. If you use it a huge amount, the $100 Claude or ChatGPT plan. A $20 plan makes sense only if you never hit its usage limit, and heavy users do.

ChatGPT Plus at $20 is worth it if you program, if your work pays for it, or if you use it professionally. For personal use, you don't need to pay that much. Is ChatGPT Plus worth it works through the cases.
