Overview

What is MaxAI?

MaxAI is an AI assistant that lives inside the browser. It ships as a Chrome and Edge extension, with a web app for people who would rather install nothing. Once added, it opens two surfaces: an AI sidebar, which answers questions about whatever page is open, and an AI context menu, which acts on any text you select, whether to improve it, translate it, explain it or draft a reply.

Its commercial argument is aggregation. Rather than paying for ChatGPT Plus, Claude Pro and Gemini Advanced separately, one MaxAI subscription reaches several model families at once, a comparison the pricing page makes explicitly. The roster is tiered: fast models such as GPT-4o-mini, Claude-3.5-Haiku, Gemini-1.5-Flash and Llama-3.2-90B; advanced models such as GPT-4o, Claude-3.5-Sonnet, Gemini-1.5-Pro, Llama-3.1-405B and Mistral-Large-2; reasoning models in limited beta; and image models including DALL-E 3, FLUX.1 and Stable Diffusion 3 Medium. That list moves quickly. The Chrome Web Store entry already cites GPT-4.1, o4-mini, Claude-3.7-Sonnet, Gemini-2.5-pro, Grok-3 and DeepSeek, and release notes running to 23 March 2026 add GPT-5 through GPT-5.2, Grok-4, Claude Sonnet 4.6 and a Gemini 3 Pro preview.

Four uses dominate. Reading faster: summarize or interrogate a page, a PDF, a research paper or a video. Writing better: rewrite, proofread, paraphrase, adjust tone, or answer an email in Gmail and Outlook, a post on LinkedIn or X, a message in Slack, WhatsApp or Telegram. Searching: sourced web answers shown beside ordinary search results. Translating: one-click bilingual translation of a whole page, in an interface available in roughly fifty languages.

Around the extension sits a large free library, with online AI tools including a prompt collection, a summarizer, an explainer and an action-item extractor, alongside PDF utilities, file converters and text comparison tools.

The Chrome Web Store records 700,000 users and 4.7 out of 5 across 14,600 ratings, with a Featured badge. The publisher describes itself as a small, independent team based in Silicon Valley, California.

What it does

  • Summarize any web page, PDF, YouTube video, article or email
  • Chat with a page, document, video or screenshot to get answers drawn from its content
  • Search the web from the sidebar and get sourced answers with links
  • Rewrite, proofread, paraphrase, change the tone of or simplify any text online
  • Reply to emails, social posts and chat messages in a single click
  • Translate a full page bilingually, or explain a selected passage instantly
  • Generate images with DALL-E 3, FLUX or Stable Diffusion 3
Audience

When to use MaxAI / When not to

A quick filter to help you decide if MaxAI is the right fit.

When to use MaxAI

  • Heavy online readers who work through long articles, research papers, PDFs and YouTube videos every day
  • Writers, marketers and communicators who draft emails, posts and copy directly in the browser
  • People working across languages, who need one-click bilingual translation and an interface in around fifty languages
  • Users who would otherwise stack ChatGPT Plus, Claude Pro and Gemini Advanced and would rather pay for one subscription
  • Individuals and freelancers on a tight budget, since the permanent free plan already covers chat, web search, reading, writing and translation

When not to use MaxAI

  • Developers who need an API: MaxAI publishes none, and its terms forbid programmatic access to the service
  • Organizations with formal compliance requirements, as there is no GDPR mention, no data processing agreement, no subprocessor list and no stated hosting location
  • Teams wanting predictable seat pricing, since team plans are offered but no team rate is published anywhere
  • Anyone working outside Chromium browsers, or looking for an iOS or Android app, as neither exists
  • Buyers who want the safety net of a refund, because all payments are final and non-refundable
Get started

How to use MaxAI

A typical end-to-end flow, from setup to results.

  1. Install the extension from the Chrome Web Store or the Microsoft Edge Add-ons store
  2. Reload any tabs that were already open, otherwise the extension will not act on them
  3. Sign in with a Google account or an email address; settings then sync across browsers and devices
  4. Open the AI sidebar on any page to summarize it or ask questions about its content
  5. Select text anywhere online to trigger the context menu and explain, translate, rewrite or reply
  6. Drop a PDF, a YouTube link or a screenshot into the sidebar to chat with it
  7. Pick the model that fits the task, query several at once, and save the prompts you reuse
  8. Optionally connect your own API key, which lifts MaxAI's usage quotas on the models it covers
  9. Use the web app or the free online tools when installing an extension is not an option
  10. Manage or cancel the subscription from Your Plan, which opens the Stripe customer portal

Trust & Privacy

Data, GDPR & hosting

A consolidated view of how MaxAI handles your data.

GDPR overview

There is no GDPR implementation to report. Across every page collected, from the privacy policy and the terms to the contact page and the full sitemap, the words GDPR, CCPA and General Data Protection do not appear once. No Article 27 representative is designated, no data protection officer is named, no legal basis for processing is stated, no data processing agreement is offered and no subprocessor list is published. No hosting country or region is disclosed either. What exists is informal: deactivating an account is said to trigger deletion from the servers within a reasonable timeframe, and marketing messages carry an opt-out. The terms are governed by California law with jurisdiction in Santa Clara County, and the Chrome Web Store listing declares the publisher a Non-trader, warning EU consumers that consumer rights do not apply to contracts with them.

Who owns the data?

MaxAI's terms make the user responsible for the content they submit and require them to own or hold the rights to it; no clause claims ownership of the outputs the tool generates. The privacy policy, dated 29 June 2023, states that the publisher holds only an email address and a name, used to recognize users at sign-in and sync their settings across devices. It declares that MaxAI collects no information about the sites visited or the content read, and sells no information to third parties. The Chrome Web Store listing repeats that data is neither sold nor transferred for purposes unrelated to the extension's core function.

Reuse rights

The terms place no restriction on what users do with the answers, summaries, rewrites or images MaxAI produces: no ownership claim, no licence-back clause and no attribution requirement appears in the document, so outputs can be reused freely. Responsibility travels with that freedom, since users must already hold the rights to whatever they feed into the service and remain accountable for it. On the publisher's side, declared uses are narrow. Email and name serve sign-in and settings sync, while automatically generated extension reports covering browser version, extension version and operating system feed functionality improvements, usage analysis and troubleshooting. Marketing messages may be sent where the law permits, with an opt-out in every message or through user settings. Nothing in the policy addresses whether submitted content is used to train AI models.

Data retention & training

Retention summary
MaxAI publishes no retention periods. The privacy policy of 29 June 2023 says personal information, including the settings needed for cross-device sync, is kept only as long as necessary to provide the service, or for legitimate business purposes such as resolving disputes, safety and security, or complying with legal obligations. Four factors are said to determine how long: the amount, nature and sensitivity of the information; the potential harm from unauthorized use or disclosure; the purposes of processing; and any applicable legal requirements. Deactivating an account is said to trigger deletion from the servers within a reasonable timeframe, again without a figure. No retention period is stated for conversations, no zero-retention option is offered and no automatic deletion setting is described. Requests go to hello@maxai.me, the only channel available.
Trains on customer data
Unclear

Hosting summary

No hosting information is published. The privacy policy, the terms and the Chrome Web Store listing name no country, no region and no infrastructure provider, and the site has no trust or security page. No certification, whether SOC 2, ISO 27001 or any other, is claimed. The only commitment offered is generic: the publisher says it applies commercially reasonable technical, administrative and organizational measures against loss, misuse and unauthorized access, while conceding that no transmission or storage method is completely secure. Two observations sit outside that silence and carry no contractual weight. Network lookups resolve the domain to 198.49.23.144, an anycast address belonging to Squarespace, Inc. and geolocated in the United States, which describes where the marketing site is served rather than where user data lives. Separately, AI requests are answered by third-party model providers including OpenAI, Anthropic, Google, xAI, DeepSeek and Mistral, whose own hosting arrangements the publisher never documents. Anyone with a data residency requirement should treat the location of their content as undetermined and ask before subscribing.

Watch-outs

Things to keep in mind

Risks and trade-offs to weigh before adopting MaxAI.

  • Promotional pricing: the USD 19 monthly rate is a limited-time 53% discount, and the standard annual rate is USD 40 per month
  • No refunds under any circumstances, on a subscription that renews automatically through Stripe until you cancel it
  • A broad Fair Usage Policy allows quotas, rate limiting, usage monitoring and suspension at the publisher's discretion, on accounts that must remain strictly individual
  • The privacy policy dates from June 2023 and is written for the Chrome extension alone, while the product now spans a web app and hundreds of online tools
  • Nothing is published about whether your prompts and documents train AI models, and requests are served by third-party providers the policy never names
  • No postal address and no full legal entity are given, any dispute runs through California law alone, and the publisher declares itself a Non-trader to EU consumers
  • Leaning on an always-present summarizer can quietly erode the habit of reading sources closely; the tool shows its citations, but only if you open them
Setup

Setup & Integrations

Technical difficulty

Minimal. Installation is a single click from the Chrome Web Store or the Edge Add-ons store, followed by sign-in with Google or an email address, after which settings sync automatically. No API key, no configuration and no deployment are required. Two quirks are worth knowing: pages already open must be reloaded before the extension acts on them, and it deliberately does not run on Chrome Web Store pages. Connecting your own API key is an optional advanced step. Anyone who cannot install software can use the web app or the free online tools instead.

Yes. A permanent free plan covers chat, web search, reading, writing, replies and translation, subject to a daily cap on AI requests. Advanced features and higher quotas require an upgrade.
Which browsers and devices does MaxAI support?
Chromium browsers only, meaning Chrome and Edge, through a browser extension, plus a web app that requires no installation. There is no iOS or Android application.
Which AI models can I use?
Several families depending on the plan, spanning OpenAI, Anthropic, Google, xAI, DeepSeek, Mistral and Meta, alongside image models such as DALL-E 3, FLUX and Stable Diffusion 3. New models are added regularly.
Can I connect my own API key?
Yes. On a paid plan, when you use your own API key, MaxAI's usage limits no longer apply to the models linked to that key.
How much does MaxAI cost?
Free is USD 0 per month. Pro is USD 20 per month billed monthly. Elite is USD 19 per month billed annually under a limited-time 53% discount, against USD 40 per month billed annually otherwise. Team plans exist but are not priced publicly.
How do I cancel, and can I get a refund?
You can cancel at any time from Your Plan, which opens the Stripe customer portal. No refund is available: the terms state that all payments are final and non-refundable.
What data does MaxAI collect?
The privacy policy declares only an email address and a name, used to identify you at sign-in and sync your settings, plus automatic technical reports from the extension. It states that the publisher does not collect the sites you visit or the content you read.
Is MaxAI GDPR compliant?
The site never mentions the GDPR. No data processing agreement is offered, no subprocessors are listed and no hosting country is disclosed, so no compliance claim can be verified from the published material.
Is there a minimum age?
The terms forbid supplying personal information about children under 13, or under the applicable age of digital consent in your jurisdiction.
Does MaxAI offer an API or an affiliate program?
There is no public API, and the terms forbid programmatic access. An affiliate program does exist, paying 25% recurring commission through a referred subscriber's first year, operated through Rewardful.
Conclusion

Should you pick MaxAI?

MaxAI is a mature, actively maintained product. Its browser extension reached version 8.37.2 on 3 June 2026, its release notes run to 75 dated entries, and the newest models tend to appear within weeks of launch. The traction is verifiable rather than merely claimed: the Chrome Web Store records 700,000 users and a 4.7 out of 5 average across 14,600 ratings, with a Featured badge from Google.

The value proposition is easy to state. Instead of paying for three model subscriptions and switching between three tabs, you get one assistant that follows you onto every page, reads what you are reading and writes where you are writing. For anyone who spends the working day inside a browser, handling long documents, answering messages or drafting in a second language, that is a real saving of attention, and the permanent free plan is generous enough to test the claim honestly.

The weakness is documentary rather than functional. The legal material has not kept pace with the product: a privacy policy from June 2023 that covers only the Chrome extension, no mention of the GDPR anywhere on the site, no data processing agreement, no subprocessor list, no stated hosting country, no postal address, and a firm no-refund policy. Nothing is said about whether submitted content trains models. Two smaller cautions deserve a mention: the headline price is a limited-time 53% discount that will expire, and the audience figures shown on the site run ahead of those on the marketplace.

The natural audience is individuals, freelancers and small teams who read and write heavily online. Organizations bound by formal compliance requirements should look elsewhere, or ask for the missing documentation before subscribing.
