AI Sidebar: Summarize YouTube & Web Pages, Chat, Write — SideZero Chrome extension security report

SideZero is an AI assistant that lives in your browser sidebar — read, write, research and create without ever leaving the page you are on. Summarize webpages and YouTube videos, ask questions about what you are reading, draft replies in Gmail, translate, edit images, run deep research, and chat with AI. All from a sidebar that works beside your page instead of in another tab. ⚡ TWO WAYS TO USE IT SideZero Free — start instantly, no API key, no card, no account: • 5 messages a day with no account at all • 20 a day once you sign in free with Google • 200 a day on Done For You, $12/month Those are the real numbers, stated here and inside the product. 200 is the whole limit — no hidden throttle, no fair-use asterisk. We never use the word "unlimited", because nobody actually sells that. 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 • 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 🖱️ 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. • OpenAI and Anthropic keys unlock their newest chat models • Google Gemini adds web-grounded answers and its own image models • xAI, DeepSeek and Moonshot (Kimi) connect the same way, each with its own strengths and its own prices • OpenRouter opens hundreds of models from one key • Ollama runs models locally on your machine: free, offline, private Every one of them 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 and YouTube summaries ✔ 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.
