delve

Read full description

Everything online wants your attention. delve gives you something back for it. A topic is one idea, explained properly: a video to watch, then prose that goes exactly as deep as you want to go. No listicles, no padding, no fifteen open tabs. Most take a few minutes, and they end โ€” there is no feed here to swallow your evening. CINEMATIC TOPICS A handful of stories are made the way a film is made. Their own colours, their own typography, photographs given the whole screen. You move through one scene at a time, and every scroll lands with a resistance you can feel. READ IN THREE DEPTHS The hook tells you why it matters. The context gives you the ground. And if you're still curious, the deep dive takes you further. A rule marks each one, and it thins as you go โ€” so you can always see how deep you are. AN AI THAT READ THE PIECE Anything still unclear, ask. It answers from the topic in front of you rather than improvising, and four good opening questions are already waiting at the end of every read. TOPIC GENERATION Nobody's library has everything. Type the thing you're actually curious about and delve writes it โ€” same format, same depth, ready in about a minute, and yours to keep. PATHWAYS Name a goal in your own words and get the route there: three to six topics in an order where each one only assumes what the one before it taught. Tick them off and the path fills in behind you. AND THE SMALL THINGS Your library, one tap away. A proper dark palette, not an inverted light one. A home screen built from interests you choose once. FREE, AND NOT THE TRIAL KIND Every topic, every cinematic story and the whole reader are free. The only limit is a daily allowance on the AI, because generation costs real compute โ€” and the app shows you exactly what you've used and when it resets. Students can ask for roughly double it; there's no form and no payment step โ€” just write us. Questions, bugs, or a story you think we should make: contact@trydelve.app
