This free-of-charge PDF reader with text-to-speech is created by team VelaTango. It comes in handy when you want to listen to a book while taking a walk or working in garden. The voice reading runs completely offline. The AI summary of PDF text and continual discussions with AI can help you better understand the content as well as getting a good picture of books and articles that you do not have time to read in detail. Privacy is fully protected with this app. PDF reading and text-to-speech are completely local and runs offline. The AI summary part requires internet connection. It sends selected PDF text directly to Google Gemini using your own API key. This app does not collect any user data. No email account needed. No login required. Please refer to instructions for details including how to download voices required by this app and how to apply for free Gemini API key if you are interested. Some notes on features: In principle, any PDF files can be loaded into this app. You can read by viewing. But when it comes to listening with text-to-speech (TTS), there are some limitations that you want to be aware of: 1) TTS part now works for PDFs with two-column text. Some text with math equations still face some challenges in separating two columns properly. 2) Voices are limited to 4 for English and 4 for Chinese to avoid the overwhelmingly long list. If you like the app and would like to add voices of other languages, please specify which language, name of the voice (like Ana), and whether the voice is enhanced or premium. Your PDF and Gemini API key files (a txt file with only the key information) are good to be kept in the same place like in the Files folder on your device. The buttons or icons on the control panel are quite intuitive. The reset icon returns voice reading back to the top of the page. When voice selection and speed selection are changed, new selection starts on the same line. I have enjoyed using this app and I wish the same for you.

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.
