Comparison

Sidenote vs MaxAI

MaxAI is a do-everything AI sidebar: chat with any webpage or PDF, summarise YouTube videos, write, translate, generate images, and pick from a dozen models. Sidenote does one thing and does it deeply: it reads the document in front of you and cites every claim back to the exact passage.

Sidenote

A citation-first reader that grounds every answer in the page you already have open.

MaxAI

A broad AI sidebar for browsing: many models, web search, writing, translation and image generation.

The short answer

Should you use Sidenote or MaxAI?

Choose Sidenote if…

Choose Sidenote when you are doing serious reading and every answer needs to be traceable to the source: reports, contracts, papers, and private Confluence, Notion or SharePoint pages, with citations that scroll and highlight the exact passage.

Choose MaxAI if…

Choose MaxAI when you want one assistant for everything as you browse: rewriting emails, translating, summarising YouTube videos, searching the web and generating images, with your pick of many AI models.

Both live in your browser and both chat with webpages and PDFs with cited answers. The difference is focus: MaxAI is a wide productivity toolkit, while Sidenote is a deep reading assistant that verifies every citation against the document server-side and drops anything it cannot ground.

Verified against maxai.co and its pricing page in July 2026. MaxAI advertises cited answers and chats with webpages and PDFs, but does not offer server-validated citations that scroll and highlight the live page, cross-document questions, or a jargon glossary. Where MaxAI is genuinely broader — web search, many models, writing, translation and image generation — we say so. The cross-document row is powered by Sidenote Collections.

The core difference

A toolbox for everything you browse, or a reader that rides along with the document.

MaxAI is built to be your one AI companion across the whole web: ask about any page, summarise a YouTube video, rewrite an email, translate a passage or generate an image, all from a sidebar. It fronts many models — GPT, Claude, Gemini, Grok, Llama and DeepSeek — and advertises cited answers, so the breadth is the point.

Sidenote is narrower on purpose. It focuses on the document you are actually reading and makes every claim traceable: click a citation and the live page scrolls to and highlights the exact passage, while the server validates each quote against the source and drops anything it cannot ground.

A concrete example

You are reading a 60-page vendor contract in your browser and ask what happens if you terminate early. MaxAI will give you a fluent, cited answer; Sidenote answers with citations you can click to jump straight to the exact clauses on the live page, and silently removes any point it cannot ground in the actual text.

Giving credit

Where MaxAI is the better tool.

MaxAI is a genuinely capable product with over a million users, and there are real reasons people love it. Here is where it clearly leads.

Breadth in one sidebar

MaxAI does far more than read: web search, writing and rewriting, bilingual translation, YouTube summaries and image generation all live in the same panel. If you want one tool for everything, that is a real advantage.

Your pick of the top models

MaxAI fronts many leading models — GPT, Claude, Gemini, Grok, Llama and DeepSeek — and lets you switch between them, so you are never locked to a single provider.

Polished and popular

With 1M+ users and a 4.8-star rating across 14,000+ ratings, MaxAI is a mature, well-designed product that many people rely on every day.

FAQ

Sidenote vs MaxAI — common questions

If your priority is trustworthy reading rather than a do-everything toolkit, yes. Sidenote focuses on the document you have open and cites every claim back to the exact passage, validating each quote server-side. MaxAI is the better fit if you want web search, writing, translation and image generation in one place.
MaxAI advertises answers with cited sources. Sidenote goes further: clicking a citation scrolls the live page to and highlights the exact passage, and the server checks every cited quote against the document and drops anything it cannot ground.
Sidenote reads private Confluence, Notion, SharePoint, OneDrive and Google Docs pages in place, with no upload. MaxAI chats with general webpages and PDFs but is not built around authenticated enterprise knowledge bases in the same way.
Neither has a native mobile app. Both are desktop browser tools — MaxAI on Chrome and Edge, Sidenote in the side panel on Chrome, Edge, Firefox and Opera — each with a companion web app.
Both are freemium. MaxAI has a free tier and a Pro plan at about 12 USD per month billed yearly (30 USD billed monthly). Sidenote is free forever with a 7-day Pro trial and no card required, with paid plans from GBP 10 per month; the top tier unlocks the most capable model.
MaxAI is oriented around the current page or file. Sidenote's Collections let you ask one question across many documents and get per-document citations, which is useful when an answer is spread across several sources.
