Panelize - Compare AI Chatbots Side by Side

Ask multiple AI chatbots at once and compare their answers side by side. Uses your own accounts. Free, no API keys.

Panelize sends one prompt to several AI chatbots at the same time and shows every answer side by side in one window. It is free and open source, and it uses the AI accounts you are already logged into, so there are no API keys and no extra subscription. HOW IT WORKS Each panel loads the chatbot's own website with your normal login. Type once in the shared input bar and click Send All. Free accounts work, and if you pay for a plan, that panel uses your plan's models and limits. SUPPORTED SERVICES 12 popular AI chat services, plus an AI search mode. Turn on the ones you use and arrange them in any order. FEATURES • Up to 12 panels in 22 layouts, from a quick 1×2 comparison to 1×12 or 2×6 • Send All, or Fill to review the prompt in every panel before sending • New Chat for All resets every panel in one click • Upload images once and attach them to every panel • Prompt Library with variables such as {topic} • Share: turn a comparison into an image to copy or download • Resize panel columns by dragging; widths are remembered per layout • Select text on any page, right-click and choose Send to Panelize • Keyboard shortcut: Cmd/Ctrl + Shift + E PRIVACY There is no Panelize server and no analytics.
