Klime Agent

You say it. Klime does it.

Describe a task in plain words. Klime Agent reads the page, clicks, types, scrolls and switches tabs — step by step, right in front of you.

  • Every step in plain sight

    Each click and keystroke shows up in the panel, and Stop is always one click away.

  • Asks before it matters

    Klime pauses for your OK before it submits, sends, buys or deletes anything.

  • Stays away from secrets

    It never types passwords or payment details and doesn’t try to solve CAPTCHAs.

Klime AI Agent

Klime AI Companion: the AI agent that works beside the page.

Klime AI Companion — also known as Klime AI Agent — is a browser extension that brings an AI agent into the side panel of Chrome and Edge. It reads the page you choose, then summarizes, explains, translates, writes and creates images right beside it.

Looking for “Klime AI Companion” or “Klime AI Agent” in your browser’s add-on store? It is the same extension, published by FitzTools.

  • Page-aware

    Answers come from the page you have open, not from a blank chat window.

  • Acts only when you ask

    Klime sends page context only when you use it. Klime Agent acts on a page only for a task you start, shows every step and asks before sending, submitting or buying.

  • One agent, two browsers

    The same Klime AI Agent for Chrome and Edge, with one free AI request every day.

FAQ

Questions, answered.

What is Klime AI Companion?

Klime AI Companion is a browser extension that puts an AI assistant in your browser side panel. You can ask questions about the page you are reading, summarize articles, explain difficult passages, translate, rewrite text, draft email replies and generate images, without leaving the tab you are on.

Is Klime AI Agent the same as Klime AI Companion?

Yes. Klime AI Agent and Klime AI Companion are two names for the same browser extension by FitzTools. The store listings use the full name, Klime AI Companion; many people simply call it Klime or Klime AI Agent.

How does Klime work?

Open Klime from the toolbar icon or with the keyboard shortcut. While the panel is open, Klime reads the page context in your browser. When you send a message or use a quick action, your request, recent chat turns and the page excerpt go through the Klime proxy to OpenRouter to generate the answer. Nothing is sent until you ask.

Does Klime work with YouTube?

Yes. On YouTube videos that have a transcript, Klime can fetch it to summarize the video and answer questions about it. If a video has no transcript, Klime cannot summarize what is said.

Can Klime help write emails?

Yes. In Gmail, Klime can draft new emails, suggest replies to the open message and polish your wording. The draft is inserted into the compose field so you can review and edit it.

Does Klime send emails automatically?

No. Klime never clicks Send. It does not use the Gmail API, does not sign in to your Google Account and does not list or download your inbox.

Can Klime translate webpages?

Yes. Klime can translate selected text and page content, and you can ask questions about a foreign-language page in your own language. Quality depends on the language pair and the text.

Is Klime free?

Klime has a free tier with one AI request per calendar day. To keep using AI the same day, choose Weekly ($4.99 per week after a 3-day free trial), Monthly ($9.99 per month) or Yearly ($39.99 per year). See Pricing.

How many free AI requests do I get?

One per calendar day, shared across all AI features. Chat, a page summary, a YouTube summary, an email draft or an image each use that same request. It is not one free request per feature.

How do I cancel my subscription?

Use the receipt or customer-portal link from Dodo Payments, or Klime's restore flow, which emails that portal link to your checkout address. Cancel before the trial or renewal date to avoid the next charge. Uninstalling Klime or clearing browser storage does not cancel a subscription.

Does Klime store my browsing history?

No. Klime does not collect your browsing history as a list. It reads page context only while its panel is open or when you use Ask AI.

What happens to the text I send to AI?

It goes to the Klime proxy on Railway and on to OpenRouter only to generate your answer. It is processed transiently; we do not keep a long-term database of your prompts or page content. Conversation history stays on your device. See the Privacy Policy.

Which browsers are supported?

Google Chrome (Chrome Web Store) and Microsoft Edge (Edge Add-ons). Klime is designed around the Chrome side panel, so some features may behave differently in other browsers.

Where can I read the Privacy Policy and Terms of Use?

Read the Privacy Policy and the Terms of Use. Both are specific to Klime AI Companion and published in English.
