Ask a question, hand an agent a whole task, cut out a background, make a video, read a document aloud: Max AI covers a whole day of AI jobs in one app, instead of a separate app for each one. Chat is only the start: attach a photo or a PDF, dictate instead of typing, check what the web says today, and switch to a different AI model mid-conversation when the task calls for it. AGENTS THAT FINISH THE JOB • Hand over the whole task: the agent makes a plan, searches the web, reads the sources and does the math • It asks you when something is unclear and sends a notification when the answer is ready • The result is a clear report with tables and a link to every source • Pick your helper: five characters, all with the same skills CHAT THAT KEEPS UP • Several leading AI models: switch between them inside one conversation • Attach photos, PDFs, Word files and spreadsheets, then ask about them • Dictate a message instead of typing it • Send a photo, a link or text into the app from anywhere on your phone PHOTO TOOLS, ONE TAP EACH • Remove the background from any picture • Upscale a photo: more detail, more resolution • Restore an old scan: scratches, creases, faded color • Colorize a black-and-white shot • Animate a still photo into a short clip • Pull the text out of a photo: a receipt, a page, a whiteboard IMAGES FROM A DESCRIPTION • A picture from a single sentence, in any style • Edit what you get: the background, the style, one detail • A library of ready-made prompts to start from VIDEO • A clip from a text description, with voiceover • A clip from a photo you already have AUDIO AND VOICE • Transcribe a recording, an audio file or a link into text • Read any text aloud in a natural voice TRANSLATION • Translate between 130+ languages • Listen to the translation • Your translation history, kept SEARCH AND RESEARCH • Answers grounded in what the web says today, with sources • Deep research: a plan first, then a sourced report FILES AND CODE • Documents and spreadsheets written for you, ready to download • Code with syntax highlighting and a step-by-step explanation MADE FOR EVERY DAY • Chat history with search, projects, and a gallery of everything you've made • Home screen widgets: new chat, image, video • A notification when a long generation or an agent's task is done, so you can leave the app meanwhile • iPhone and iPad, in English and Russian SUBSCRIPTIONS Max AI offers auto-renewable subscriptions: - Pro: 1 month - Pro: 3 months - Max: 1 month - Max: 3 months Payment is charged to your Apple Account at confirmation of purchase.
