AI Chat vs Chatmark

Meet AI Chat — one assistant that runs on the world's best AI models and automatically picks the right one for every question you ask. Stop guessing which AI to use. ASK AI ANYTHING — AND ACTUALLY ENJOY READING THE ANSWER Get replies that are clean and easy to read: clear headings, bullet points, tables and ready-to-copy code blocks — more like a polished blog post than a wall of text. Copy a full reply or just a single line, and regenerate any answer for a fresh take. AUTO MODE — THE BEST MODEL, EVERY TIME Auto reads your prompt and routes it to the most suitable model from 100+ options, so you get a more accurate answer without picking a model yourself. Premium members get unlimited Auto usage — no daily message limits. ALWAYS THE NEWEST AI AI Chat is powered by today's leading models — including GPT-5.2, Gemini, Claude, Grok, Kimi and Nano Banana — and we add or update models the same day or the day after they launch. You're always on the newest AI. GENERATE & UNDERSTAND IMAGES Turn any prompt into original artwork with unlimited AI Studio image generation (more image models on the way). Try realistic AI photo styles and filters. Upload a photo for instant analysis — identify objects, read documents, or estimate the calories in a meal. ONE APP FOR EVERYTHING - Writing: emails, essays, social posts, business ideas, brainstorming - Study & school: step-by-step math solver, homework help, clear explanations - Coding: write, explain and debug code - Translate across languages - Scan & summarize documents and photos - Health, education and everyday helpers WORKS EVERYWHERE YOU DO Sign in with your Apple or Google account and pick up every conversation across all your devices.
