PageGrok vs Kimi Copilot and Kimi Browser Assistant: choosing a webpage summarizer

Published August 27, 2026 · UpdatedAugust 28, 2026

Installing a browser AI extension usually starts with creating an account, and only then gets to the page you wanted to ask about. Both Kimi-related extensions work in that order: step two of each setup guide is signing in to Kimi.

PageGrok reverses the order. Install it, open the side panel, and ask about the page in front of you — built-in AI comes with a free trial that needs no email, no account and no card. This comparison covers four things: whether you have to sign up to start, whose model runs, where content goes, and whether you can ask about one part of a page.

First, know which one you found

Searching the Chrome Web Store for a Kimi webpage summarizer returns two extensions with similar names, built by different people.

• Kimi Copilot - 网页总结助手, developer kimi.tools. Its own store description says it is built by a third-party enthusiast and is not a product of Kimi.ai or Moonshot AI. Every page you read passes through that third-party developer’s extension, including the ones you can only see after signing in.
• Kimi 浏览器助手, developer site kimi.com. This is the official one. Its store page shows a last update of May 2025, more than a year ago.

Both require a Kimi account, both run only Kimi’s models, and both declare in the store that they handle website content. Those three follow from what the products are, and no redesign will change them.

Ask first, configure later

Install it, open the side panel, and ask about the page in front of you. Built-in AI is the default path: the free trial needs no email, no account and no card, and no model service to install first. After the trial there is an optional pass — US$5 for 500 answers over 30 days, with Alipay and WeChat as a one-time 30-day purchase that simply expires and charges nothing again.

Get your first answer first; configuration can wait.

You decide which model runs

Both Kimi extensions run Kimi’s model, and you cannot change it. PageGrok is tied to no one: built-in AI works the moment you install, and you can also connect Ollama, LM Studio or oMLX on your own machine, or any OpenAI-compatible endpoint with your own API key, self-hosted gateways included. The model list is read from the service at runtime, so anything you have pulled or loaded shows up in the picker.

Use built-in AI today, switch to Ollama once you install it, move to a stronger model next month — the reading experience holds and the choice stays with you. Running a model on your own machine has one more consequence: page content moves only between your browser and that model, reaching no third party, including us. Internal documents, client material and unpublished drafts can all be read that way.

Ask about one part of a page

Whole-page summaries are fine on cleanly structured articles. On long forum threads, product pages mixing specs with reviews, or documentation where navigation runs into the body, a whole-page summary gets diluted — the model works through navigation and ads and hands you something generic.

PageGrok’s selection mode lets you click the regions you want: one at a time, or several non-adjacent ones merged into a single piece of content. Navigation, sidebars and ads never enter the request, so there is less waiting and the answer lands on the part you care about. Both Kimi extensions summarize whole pages.

What PageGrok concentrates on

PageGrok does one thing: it reads the page you have open and answers questions about it. The scope is deliberately narrow, and two things come out of that.

Conversations stay on your machine. Your reading history reaches nobody’s server, and you can export it whenever you want.

It reads the text in your tab. Text you can see on the page is text it can read, including dashboards and internal tools that appear only after you sign in, and pages the front end assembles after load.

When to pick Kimi

One case: you already have a Kimi account, read almost entirely in Chinese, want whole-page summaries, and do not mind whose servers your content crosses. Then the official Kimi 浏览器助手 is the simpler choice — weigh the year-old last update yourself.

If you still want to change models, skip one more signup, keep some pages off the network, or ask about a single part of a page, any one of those four points to PageGrok.

Install it, open the side panel and ask — the free trial needs no signup. To run a model on your own machine instead, point it at that service in settings.

For current pricing, quotas and features on the other side, check the store listings and each vendor’s own site. The figures above were read on 2026-08-28.

FAQ

No. Install it, open the side panel and ask. Built-in AI starts with a free trial — no email, no account, no card. Step two of both Kimi extensions' setup guides is signing in to Kimi.

Is Kimi Copilot made by Kimi?

No. The Chrome Web Store listing for "Kimi Copilot - 网页总结助手" names kimi.tools as the developer, and its own description states that it is built by a third-party enthusiast and is not a product of Kimi.ai or Moonshot AI. The official extension is called "Kimi 浏览器助手", lists kimi.com as its developer site, and its store page shows a last update of May 2025. (Checked 2026-08-28.)

Can PageGrok switch models?

Yes. Built-in AI, Ollama or LM Studio on your own machine, oMLX on Apple Silicon, or any OpenAI-compatible endpoint with your own API key — switch any time. On a model running on your own machine, page content never leaves it.

Can PageGrok summarize just part of a page?

Yes. Selection mode lets you pick one region or several non-adjacent ones, merged into a single piece of content for the model, with navigation, sidebars and ads left out. Both Kimi extensions summarize whole pages.

Can you run both?

Yes. They do not conflict, and each keeps its own button and settings.
