AI image generation turns a text prompt into original images for book covers, social posts, postcards, and concept art.

Document analysis takes a PDF, TXT, or DOCX and returns instant summaries, rewrites, and answers about its content. Web browse and search bring you up-to-date answers with real sources and links you can verify. Image-based search identifies a place, landmark, or object from a photo and finds what is nearby. Hands-free voice lets you talk to AI and hear spoken answers while cooking, driving, or on the move. The writing assistant drafts emails, essays, stories, songs, and blog posts, then rewrites or polishes them in your own voice. Coding help generates and explains code, including SwiftUI, with step-by-step guidance. Learning and homework support lets you practice languages through interactive stories and work through school problems one step at a time. Smart summaries condense long articles, videos, and documents into the key points in seconds. USE CASES: Write, rewrite, summarize, and translate everything from emails to essays.

Vidsum tells you what's worth your time. Paste a YouTube link — or search right inside the app — and get a structured read of the video in under a minute: chapters you can tap to jump to, the key quotes, a summary, and an honest take on whether the video is actually worth watching. WHAT YOU GET Chapters — the video broken into sections with timestamps. Tap any chapter to jump straight to that moment. The Take — a straight answer to "is this worth my time?" Quotes — the lines that actually matter, with timestamps. Summary — short or in depth, your call. Ask — chat with the video. Ask follow-up questions and get answers grounded in what was actually said. Transcript — a synced, karaoke-style transcript that follows along as the video plays. Tap a line to jump there. BUILT FOR WATCHING, NOT JUST READING Play the video right inside the app while the analysis sits beside it. Rotate to landscape for cinema mode — video on one side, chapters and quotes on the other. Swipe up on the video to read the comments without leaving the screen. QUEUE UP A SESSION Line up several videos and let Vidsum analyse them one after another in the background. Come back to a stack of ready summaries. A broken video never stops the queue. YOUR SUBSCRIPTIONS, SUMMARISED Connect your Google account and Vidsum pulls in the latest uploads from the channels you already follow, so you can triage your feed instead of scrolling it. PRICING Free: 2 hours of analysis per month, videos up to 60 minutes, chapter titles and timestamps unlocked, 5 Ask messages a day. Pro: 120 hours of analysis per month, no video length limit, full analysis unlocked, unlimited Ask with saved history, synced transcript, the queue, and export.
