Read full descriptionHide 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

Learn vocabulary. Remember forever. Fluenzi helps you build vocabulary with structured, CEFR-aligned word lists organized by language level. Start with the foundations at A1 and work your way through increasingly advanced vocabulary. Instead of simply studying word lists, you actively practice what you're learning. Use smart flashcards, match words with their translations, train your listening, practice dictation, and revisit vocabulary through spaced repetition. Vocabulary for your level Fluenzi's vocabulary is organized around the CEFR levels used for language learning across Europe, making it easier to focus on words appropriate to where you are now โ and see where you're heading next. Choose your language and level, then let Fluenzi turn that vocabulary into daily practice. Practice in different ways Use smart flashcards for active recall, train your listening skills, practice dictation, or challenge yourself to match words with their translations. Different exercises help you recognize and recall vocabulary from different angles. Remember what you learn Fluenzi uses spaced repetition to bring words back when they need your attention. Words you know well appear less often, while words that need more practice keep coming back. Learn by listening Listening Practice plays words in the language you're learning and asks you to translate them. Dictation Practice goes a step further: listen carefully and type exactly what you hear. You can also slow down pronunciation or hear a word again. Make the connection Matching Practice gives you a quick, visual way to connect words with their translations. Find the pairs, clear the board and keep going. Follow your progress See how much you've practiced, how accurately you're answering, and how your learning develops over time. Streaks and XP give you a little extra motivation to keep going. Designed for focused learning Fluenzi keeps the experience simple and puts practice first. Your learning history and preferences stay on your device, and you don't need an account to start learning. Whether you're starting a new language or expanding vocabulary you already know, Fluenzi gives you several ways to practice โ and a reason to come back tomorrow.

The clearest difference is ads: delve at none against Fluenzi's shown. delve also leads on update cadence (every 4 days vs every 5 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
