Here is the verdict.

ContextBolt is the pick if the problem is what you read last month rather than the tab in front of you. It keeps what you saved, captures your X, Reddit and LinkedIn saves automatically, tags it all, and on Pro your agent can search it by meaning during the task. MaxAI is a sidebar for the page you are looking at right now, for highlighting, explaining, rewriting, translating and chatting with the PDF. It has no yesterday, which is the whole difference. ContextBolt is also $6 a month against MaxAI Pro at $20. Basic is free.

Where ContextBolt wins
  • It has a yesterdayA sidebar only knows the current tab. ContextBolt holds the two hundred things you decided were worth keeping and can hand any of them back months later.
  • Your social saves come in on their ownHit save on X, Reddit or LinkedIn and it lands in the library. No selecting, no clipping, no second habit to maintain.
  • A third of the price, and no models to pay twice for$6 against $20 for MaxAI Pro. ContextBolt does not sell you model access you already have, it gives your existing agent something it lacks.
What MaxAI is built for
  • Instant actions on selected textHighlight anything and explain, translate or rewrite it without leaving the page. That is a sidebar's job. ContextBolt keeps the page so the same text is still there next month, and your agent does the explaining from it.
  • Chat, PDFs and videoA multi-model chat sidebar on any page, plus chatting with documents and YouTube. ContextBolt answers the chat you already have rather than adding another one.
  • Different jobs, not rival jobsMaxAI acts on content. ContextBolt remembers it. Running both is cheaper than either one doing the other badly.

The longer story.

MaxAI is a good sidebar. Highlight a paragraph, get it explained. Select a sentence, get three rewrites. Chat with the PDF you have open, or the video you are watching.

Everything in that list has one thing in common. It happens to whatever is on screen. ContextBolt is for everything you already closed.

A sidebar has no yesterday

Say you are rewriting the paragraph on your landing page that explains the hardest feature. MaxAI will give you five versions of that paragraph, quickly, and some of them will be better than what you wrote.

None of them will know that in March you read a genuinely brilliant explanation of the same idea on a competitor’s engineering blog. Or that a customer on Reddit described exactly which part confuses people. Or that you kept an X thread because the analogy in it was perfect.

Those three things are the difference between a smoother paragraph and a correct one. A sidebar cannot reach any of them, because it only ever sees the current tab.

ContextBolt is the part that remembers

Web pages save in one click and keep their article text. Your X, Reddit and LinkedIn saves arrive without a second step, because it captures the save as you make it. Every save gets AI-tagged as it lands.

Then search runs on your machine over the tags and the full text, so “explaining rate limits to non-technical users” finds the piece you could not have named. On Pro, the same library is an MCP endpoint, so Claude or Codex can pull those sources while it helps you rewrite the paragraph.

$6 against $20

MaxAI is $20 a month for Pro and $40 for Elite, or $19 a month billed yearly. Most of that is model access, because a chat sidebar has to pay for every message.

ContextBolt Pro is $6 and includes no models. The thinking happens in the agent you already pay for. That is why it costs a third as much and why it does not duplicate anything you already have.

Basic is free with no clock on it, so you can see whether the capture is worth anything before paying.

Where MaxAI still fits

MaxAI is for AI on the page in front of you. Text actions on a selection, translation, a chat sidebar, and talking to the PDF or video you have open. That is its job.

It is not the job this page is about. ContextBolt is not a sidebar and runs in desktop Chrome, and it is built for what a sidebar cannot reach, the things you saved and closed. Running both is $26 and covers both problems properly, and Basic is free up to 150 bookmarks.

The test

Save the way you already save for a week and change nothing.

Then ask your agent for something only your own saves could answer. No sidebar can do that, at any price. Start free with ContextBolt Bookmarks, or see how to connect it to Claude Code.

Common questions.

Do these two compete?

Barely. MaxAI acts on the page in front of you. ContextBolt remembers pages you closed weeks ago. If you want both behaviors, run both, which costs $26 and is still cheaper than expecting either one to do the other's job.

Can ContextBolt rewrite or explain text?

No. Text actions, chat and translation are the sidebar's job. ContextBolt saves pages with their text, captures your social saves, tags everything and answers search. The rewriting happens in whatever agent you already use, which can now see your sources.

Why is it so much cheaper than MaxAI?

Because you are not buying model access twice. MaxAI's $20 largely pays for the frontier models behind its sidebar. ContextBolt's $6 pays for capture, tagging, sync and an MCP endpoint, and leaves the thinking to the AI you already subscribe to.

What does the free plan cover?

Basic costs nothing and has no clock on it. One-click web saving with the page text, automatic capture of your X, Reddit and LinkedIn saves, AI tagging and ranked local search. Basic is capped at 150 bookmarks.

How does a saved library make a rewrite better?

Because the useful input is usually not on screen. When you rewrite a feature explanation, the thing that helps is the clearer version you read last month and the customer question that showed you what confuses people. Ask your agent for those and work from real material.
