MaxAI Review 2026: Pricing, Features, Pros & Cons
MaxAI puts GPT-5.1, Claude Sonnet 4.5, Gemini 3 Pro, Grok 4 and DeepSeek R1 behind one shortcut on whatever page you are already on. The pitch is strong and the model roster is real — but the $12 you see on the pricing page is a discounted annual rate against a $30 monthly one, and the terms say payments are final. Here is the honest read.
Quick Verdict
Best for: heavy web readers and repliers who want frontier models in-page, and who would rather hold one subscription than three. Not for: anyone already paying for ChatGPT Plus or Claude Pro who mostly works in a single chat tab.
What Is MaxAI?
MaxAI is a browser extension for Chromium browsers that overlays an AI assistant onto every page. Select text to rewrite, summarise, translate, simplify or explain it; open a chat against the page, a YouTube video, a PDF, an email or an uploaded file; or generate a reply directly inside Gmail, Outlook, LinkedIn, Slack, Discord, WhatsApp, Telegram and a long list of other surfaces.
What separates it from a single-vendor assistant is the model roster. Rather than one lab's model, MaxAI resells access across OpenAI, Anthropic, Google, xAI, Meta and DeepSeek, split into Fast, Smart and Think tiers, plus a set of image models. The ask-multiple-models feature runs one prompt across several at once, which is the most practical use of that breadth: agreement between models is a much better reliability signal than a single confident answer.
The commercial picture needs care. The pricing page leads with $12 per member per month, but that is a limited-time 60% discount on annual billing; monthly is $30. The terms state that all payments are final and non-refundable, and that programmatic access and account sharing are prohibited. None of that makes the product bad — it makes the free tier the correct starting point rather than an optional one.

Add it to the productivity category — a free listing publishes after review, and it is the same page ChatGPT, Perplexity and Google read when someone asks which AI extension to install. Want it live in minutes with a Verified badge instead? That option is on the form, one-time, no subscription.
MaxAI Pros & Cons
✓ Pros
- •One subscription reaches an unusually wide model roster — GPT-5.1, Claude Sonnet 4.5, Gemini 2.5 Pro and Gemini 3 Pro, Grok 4, Llama 3.1 405B, DeepSeek V3 and R1 — so you are buying access to a shifting frontier rather than betting on one lab
- •Ask-multiple-models runs the same prompt across several models at once, which is the fastest honest way to find out whether an answer is model-specific or actually reliable
- •It works on any page in any Chromium browser, so the assistant meets you inside Gmail, LinkedIn, a PDF, a YouTube video or a support ticket rather than making you paste content into a separate tab
- •AI reply covers the surfaces where replying is actually tedious — Gmail, Outlook, LinkedIn, Slack, Discord, WhatsApp, Telegram, Instagram, X, Messenger and YouTube — which is a broader integration list than most competitors publish
- •Image generation is bundled at no extra credit cost on Pro, spanning GPT-Image-1, DALL-E 3, SD3-Medium and the FLUX Schnell, Dev and Pro line
- •The free tier is genuinely useful rather than decorative: unlimited chat on the fast free model plus 3 Pro chats a day is enough to learn whether the workflow sticks
- •Ask-any-source handles webpages, YouTube, PDFs, email, files, images and audio through the same interface, which removes a lot of tool-switching from research work
- •Side-by-side page translation and select-text translation are built in, which is a real advantage for anyone reading in a second language every day
✗ Cons
- •The advertised $12/month is a limited-time 60%-off annual rate — the honest monthly price is $30/month, and anyone comparing against ChatGPT Plus or Claude Pro should compare against $30, not $12
- •MaxAI states that all payments are final and non-refundable, so a subscription bought on the discounted annual rate is a full year of committed spend with no exit
- •The terms explicitly forbid programmatic access and account sharing, meaning there is no API and no automation path — this is a human-in-the-browser product only
- •Chromium-only: Chrome and Edge are supported, and Safari and Firefox users are simply not served
- •Many of the headline models carry a Beta label, including GPT-5.1, Gemini 3 Pro, Grok 4 and DeepSeek R1, so availability and behaviour on any given day are not guaranteed
- •The free tier caps Pro chats at 3 per day, which is roughly one real task, so the free-to-paid pressure arrives fast for anyone who actually adopts it
- •You are trusting a third party with page content across every site you enable it on, which is a materially larger data-exposure surface than pasting into a single chat app
- •Being a reseller of frontier models means no depth in any one of them — no Claude Projects, no ChatGPT memory across devices, no OpenAI-native tooling, just the chat surface

Who Should Actually Buy MaxAI
Buy it if: most of your day happens in a browser and the friction you want removed is copy-paste; you reply to volume across email, LinkedIn and chat apps; you read or translate in a second language daily; or you genuinely want several frontier models side by side and would otherwise be paying two or three subscriptions to get them.
Skip it if: you already pay for ChatGPT Plus or Claude Pro and work mostly in one chat tab, where you are paying twice for the same intelligence with less depth; you use Safari or Firefox, which are unsupported; you need an API or any automation, which the terms prohibit; or you handle confidential data on pages where a third-party extension would need review you are not going to get.
Frequently Asked Questions
How much does MaxAI cost in 2026?
MaxAI has a free plan with unlimited chat on its fast free model, 3 Pro chats per day and limited file uploads. Pro is advertised at $12 per member per month billed yearly, described on the pricing page as a limited-time 60% discount, against a stated $30 per member per month when billed monthly. Pro unlocks unlimited Pro chat, the Smart and Think model tiers, image generation, higher file upload limits and team member management. There is no separately priced enterprise tier — any paid plan can add members at the same per-member rate. Read the terms before buying the annual rate: MaxAI states that all payments are final and non-refundable.
Which AI models does MaxAI include?
The roster is unusually broad and split into three tiers. Fast covers GPT-5-mini, Claude Haiku 4.5, Gemini 2.0 Flash, Grok 4 Fast, Llama 3.3 70B and DeepSeek V3. Smart covers GPT-5.1, Claude Sonnet 4.5, Gemini 2.5 Pro, Grok 4 Fast reasoning, Llama 3.1 405B and GPT-4.1. Think covers GPT-5.1-thinking, Gemini 3 Pro, Grok 4 and DeepSeek R1. Image generation spans GPT-Image-1, DALL-E 3, SD3-Medium and FLUX Schnell, Dev and Pro. Several of these carry a Beta label, so treat day-to-day availability as best-effort rather than contractual.
MaxAI vs Sider vs Monica — which is best?
They are close enough that price and platform decide it. All three are browser-based multi-model assistants with in-page chat, summarisation, rewriting and reply generation. MaxAI's edge is the breadth of the model roster and ask-multiple-models; its weaknesses are Chromium-only support and a no-refund policy. Sider spreads wider across platforms including mobile. Monica pairs the extension with a desktop app. If you compare on the true monthly rate rather than the promotional annual one, MaxAI at $30/month is the most expensive of the three, so the honest recommendation is to run all three free tiers for a week and buy the one you actually reach for.
Is MaxAI worth it if I already pay for ChatGPT Plus?
Only for the placement, not the intelligence. If you already pay for ChatGPT Plus or Claude Pro you have the same frontier models with more depth — memory, projects, native tooling — than a reseller can offer. What MaxAI adds is that the assistant sits on the page you are already reading, so summarising a long article, rewriting a LinkedIn reply, or asking a question about a PDF takes no copy-paste. That convenience is real, but it is a $30/month convenience on top of a subscription you already hold. Try the free tier for a fortnight and count how often you actually used it in place of opening a chat tab.
Is MaxAI safe to use on private pages?
It is a mainstream extension used at scale, but the security question is structural rather than about this vendor specifically. To function, an in-page assistant needs access to the content of pages you invoke it on, which can include email, internal dashboards and customer data. That is a materially broader exposure surface than pasting a single document into a chat app. If you work with regulated or confidential data, check the extension permissions, restrict which sites it runs on, and get the same sign-off you would need for any other third-party processor. For general web reading, the trade-off is ordinary.
Can I cancel MaxAI and get a refund?
You can cancel, but do not expect money back. Cancellation is self-service — open Your Plan and click through to manage the subscription in Stripe's customer portal — and it stops future renewals. Refunds are a different matter: MaxAI's checkout terms state that all payments are final and non-refundable. That makes the annual plan the riskier purchase despite the better rate, and it is the single strongest argument for spending a fortnight on the free tier, then a month on the $30 monthly plan, before committing to a year at $12.
