AI Sidebar — ChatGPT, Claude, Gemini — FREE & Unlimited

AI Sidebar & AI Assistant for Chrome. Chat with ChatGPT, Claude & Gemini in one side panel. 100% free, with unlimited usage.

AI Sidebar brings ChatGPT, Claude, and Google Gemini together in one browser side panel — chat, write, summarize, translate, and research with the world's best AI models while you browse, without ever switching tabs. No sign-up. No subscription. No usage limits. You log in to the AI accounts you already have, and everything your accounts include — free or paid — works instantly. AI Sidebar is completely free, forever. ━━━━━━━━━━━━━━━ ⭐ WHY AI SIDEBAR? ✅ 100% free & unlimited — no premium plan, no credit system, no daily caps. We don't sell anything. ✅ All three top AIs in one place — ChatGPT, Claude, and Gemini, one click apart ✅ Truly private — your chats go directly to OpenAI, Anthropic, and Google. We never see, store, or proxy a single message. ✅ Featherlight — a fraction of a megabyte. No bloat, no background processes draining your laptop. ✅ The real apps, not an imitation — you get the official ChatGPT, Claude, and Gemini interfaces with your full chat history, projects, custom instructions, and settings ━━━━━━━━━━━━━━━ 💬 CHAT WITH THE BEST AI MODELS Use every model your accounts unlock — GPT-5 and the o-series reasoning models on ChatGPT, Claude Opus and Sonnet on Claude, Gemini Pro and Flash on Gemini. Free tiers of all three work out of the box, and paid subscriptions carry over automatically because you're using the real sites. 📸 ASK AI ABOUT WHAT YOU'RE LOOKING AT One click on "Add screenshot" captures the page you're viewing and drops it straight into the chat. Then just ask: • "Summarize this article" • "Explain this chart" • "Translate this page" • "What does this error message mean?" • "Is this a good deal?" 🖱️ RIGHT-CLICK → ASK AI Select any text on any website, right-click, and choose "Ask AI". The sidebar opens with your selection — plus the page title and link for context — already in the chat box. Perfect for: • Explaining confusing paragraphs, contracts, or legal terms • Fact-checking claims while you read • Translating foreign-language snippets • Simplifying technical documentation ✍️ WRITE ANYTHING, ANYWHERE Keep the sidebar open while you work: draft emails, reports, cover letters, essays, social posts, and replies — then paste them wherever you're working. Ask for rewrites, tone changes, grammar fixes, or shorter versions without losing sight of the page. 🔀 COMPARE AI ANSWERS SIDE BY SIDE Not sure which AI is best for the job? Ask ChatGPT, switch to Claude, then Gemini — one click each — and compare answers to the same question. Use the model that's strongest for each task: coding, creative writing, research, or analysis. ↗️ TAKE CONVERSATIONS FULL-SCREEN The "Open in new tab" button moves your current conversation — the exact chat, not just the homepage — into a full browser tab whenever you need more room. 🧠 IT LEARNS YOUR HABITS The sidebar remembers which AI you used last and opens right back to it. Hide the AIs you don't use in Settings to keep the interface spotless. 🌓 DESIGNED TO DISAPPEAR A clean, minimal interface with automatic light and dark mode that matches your browser — so the focus stays on your conversation, not our chrome. ━━━━━━━━━━━━━━━ 👩‍💻 WHO IS IT FOR? • Students — summarize readings, explain concepts, check essays • Professionals — draft emails, prep meetings, digest long reports • Developers — debug errors, explain code, compare model answers • Writers & creators — brainstorm, outline, rewrite, translate • Researchers — question sources as you read them • Anyone who chats with AI more than once a day ━━━━━━━━━━━━━━━ 🔒 PRIVACY, FOR REAL AI Sidebar is a window to the official AI websites — nothing more. Your messages, files, and credentials travel directly between your browser and OpenAI, Anthropic, or Google. We run no servers, collect no analytics, track no browsing, and store nothing about you. The extension can't read your conversations, and we like it that way. ━━━━━━━━━━━━━━━ ❓ FAQ Is it really free? — Yes. The extension is 100% free with no limits. Your AI accounts' own plans (free or paid) determine which models you get. Do I need accounts? — Just the free accounts you probably already have: OpenAI for ChatGPT, Anthropic for Claude, Google for Gemini. Use one, two, or all three. Does my ChatGPT Plus / Claude Pro / Gemini Advanced subscription work? — Yes, automatically. You're signed in to the real sites, so all your benefits carry over. Will I lose my chat history? — No. It's all there, synced with your accounts, in the sidebar and on the web. ━━━━━━━━━━━━━━━ 🚀 GET STARTED IN 10 SECONDS Click the AI Sidebar icon (pin it for one-click access) Pick ChatGPT, Claude, or Gemini Sign in and start chatting alongside any page Available in 12 languages: English, Español, Français, Deutsch, Italiano, Português, Русский, 日本語, 한국어, 中文, العربية, हिन्दी.
