AI Sidebar

Bring Your Own AI — connect your own provider key and every feature works free, forever, with no cap from us. Requests go straight from your browser to the provider you chose.

📖 READ FASTER Understand a page in seconds instead of minutes.

• Summarize any webpage — articles, documentation, long threads
• Summarize YouTube videos, transcript-aware, with timestamps you can

click to jump straight to the moment

• TikTok and Vimeo work too — transcripts and summaries for short

videos and talks

• Ask questions about the page you are on
• Pull out the key points, or a TL;DR
• Explain a difficult passage simply
• Turn a page into study notes
• Translate a whole page, or just the part you selected
• Listen to a reply read aloud in a natural voice

📸 CAPTURE AN IMAGE OR ANY PART OF THE PAGE Draw a box around an image, a chart, or any area of the page — SideZero captures it so you can ask about it.

• Image to prompt: capture any picture and get the prompt that would

recreate it in your image generator

• Explain a chart or graph — trends, outliers, what it actually says
• Read the numbers out of a dashboard or a screenshot, or turn a

captured table into text you can copy

• Decode an error dialog and get the likely fix
• Translate text baked into an image — menus, signs, scanned pages

The capture is shrunk in your browser and sent only to the model you chose, like any other message. Works on SideZero Free with a free sign-in, or on your own key.

🖱️ AI EVERYWHERE, ON RIGHT-CLICK Highlight text anywhere on the web and act on it without copying it anywhere: explain, translate, rewrite, improve, fix grammar, summarize, define, or ask your own question about the selection.

✍️ WRITE ANYWHERE Writing help that can see the page you are writing about.

• Draft Gmail replies that already know what the thread said
• Write professional emails from a one-line brief
• Fix grammar and spelling, or rewrite a clumsy paragraph
• Change the tone, expand a thin draft, condense a long one
• Write blog posts and social content
• Reply in place on social sites, forums and comment threads

Set up your own writing profile once and SideZero matches your tone whenever it drafts an email, a comment or a reply.

🔬 DEEP RESEARCH When you need more than a quick answer, Deep Research reads many sources and returns a structured, cited report — market research, competitor analysis, product comparisons, technical documentation, academic work, business planning, buying guides.

• The estimated cost is shown BEFORE the run starts
• Reports are saved inside SideZero, so returning to one later costs

nothing — you never pay twice for the same research

• Export any report as HTML to share, print or archive

🎨 GENERATE AND EDIT IMAGES Create and edit images without leaving the browser, on your own key.

• Generate an image from a description
• Edit an image you already have
• Remove an unwanted object, or the text baked into a picture
• Repaint just the area you brushed
• Logos, illustrations, avatars, product shots

The exact price is shown before you generate, and the real cost after.

💱 PRICES IN YOUR CURRENCY Shopping somewhere that prices in another currency? SideZero converts every price on the page at live mid-market rates. The arithmetic is done by the extension, never by the model — language models invent exchange rates, we measured it — so the numbers are simply right.

🎤 VOICE Dictate a question instead of typing it, and have answers read back to you at a speed you choose. Useful while cooking, commuting, or when reading a screen is the hard part.

🤖 BRING YOUR OWN AI Already paying for an AI provider? Add your key and SideZero talks to it directly from your browser. Keys from OpenAI, Anthropic and Google unlock their newest chat models, web-grounded answers and image models. Want more choice? A single OpenRouter key opens hundreds of models, and Ollama runs models locally on your machine: free, offline, private. Every provider shows its real per-reply cost. Or skip all of it and use SideZero Free.

🔒 PRIVACY, AND HOW TO CHECK IT On your own key:

• Your key is stored only in this browser. We never receive it.
• Requests go straight from your browser to your chosen provider.
• Your pages, your prompts and your conversations never touch our

servers. Chat history stays on your device, and you can clear it. On SideZero Free, your message is relayed by our server so Zero can answer it — we count messages, never store what is in them. Don't take our word for either one: open DevTools and watch the network traffic yourself, or read the walkthrough at sidezero.app/verify.

💰 THE REAL COST, ON SCREEN Most AI tools never tell you what a reply cost. SideZero does.

• The estimated cost of a research run, before it starts
• The price of an image, before you generate it
• Live token counts on every reply, and a running session total
• Costs converted into your own currency

🚀 BUILT FOR EVERYDAY BROWSING The sidebar sits beside whatever you are already doing — a page of search results, your inbox, a YouTube video, documentation or a long thread on GitHub, a news article, a forum argument, a product page you are trying to price. It stays with the page, so asking one question never costs you a tab.

⭐ WHY SIDEZERO ✔ AI chat beside any webpage ✔ Webpage, YouTube, TikTok & Vimeo summaries ✔ Capture an image or page area and ask about it ✔ Writing help that knows the page ✔ Gmail drafting in your own tone ✔ Right-click actions on any selected text ✔ Deep research, saved and exportable ✔ Image generation and editing ✔ Voice input and natural speech ✔ Many providers, or local models with Ollama ✔ Every cost shown, in your currency ✔ Caps stated out loud, never "unlimited"

🚫 WHAT WE DON'T DO No ads. No content injected into your pages. No selling your data. No reading pages in the background — SideZero reads a page only when you ask it to. No fake "free" that quietly meters the key you already pay for. No surprise walls: the numbers on this page are the numbers in the product.

Share your link and you both get bonus messages when a friend signs in. One-time, no strings.
