Duolingo is an app and website designed to help people learn languages in a simple and engaging way. It’s free to use, though there are paid options that remove ads and offer extra features. The lessons are short and interactive, with exercises that involve matching words, listening to sentences, speaking, and translating. A green owl named Duo acts as the app’s mascot—offering encouragement when you stay on track and reminders when you don’t. The platform offers a wide range of languages, from widely spoken ones like Spanish, French, and Chinese to less common choices like Welsh, Hawaiian, and even fictional languages like Klingon and High Valyrian. Lessons focus on practical, everyday communication—like ordering food or asking for directions—though you’ll occasionally encounter quirky sentences that are memorable in their oddness. Duolingo adapts to your progress: if you’re struggling, it slows down; if you’re doing well, it introduces more challenging material. There are game-like features—points, streaks, and levels—that keep learning motivating and fun. For those looking to go beyond basic lessons, Duolingo also offers podcasts, stories, and interactive exercises to improve listening and reading comprehension. Convenient and easy to use, Duolingo fits into almost any schedule—you can practice on the bus, during a lunch break, or before bed. While it’s not a complete substitute for full immersion or in-depth study, it’s a useful tool for beginners and a good way to keep language skills fresh.

This was my go-to page at the early stages of learning Mandarin. Chinese Grammar Wiki has an articles of each of the main aspects of Chinese grammar. For example, there are articles on how to use 一下, 在, 要, 就是, 才and many other Mandarin grammar points. Each word gets its own article with examples in pinyin and characters and, of course, English translations. You can also get website as a physical book or an ebook.

Drops is a language learning app that focuses on teaching vocabulary through quick, visual-based games. The idea is to make learning feel more like playing, with short sessions you can fit into your day. Instead of grammar-heavy lessons, it leans on matching words with pictures, swiping, and tapping to help words stick in your memory. The app covers over 40 languages, from common ones like Spanish and French to less common ones like Hawaiian and Ainu. You get common, everyday words and phrases to start with—things you’d actually use in conversation. It’s built for people who want to learn at their own pace, and there are features like reminders and streaks to keep you coming back. Drops keeps lessons short—usually five minutes—so it’s easy to squeeze in some learning while waiting for coffee or riding the train. There’s a free version with ads and limits on daily use, or you can pay for Premium to get rid of ads, unlock all content, and use it offline. Overall, it’s not going to teach you complex grammar or how to hold a full conversation right away, but if you’re looking to build your vocabulary in a fun, no-pressure way, it does the job.

Learning a new language is hard, you need a lot of repeated exposure to the same words to make them stick. Here's the trick I use. I open ThaiPod101's live channel and let it run in the background while I do something else. For example, I can have it open while cooking dinner or tidying up. Even if I look at the screen only occasionally, I still get the benefits of being repeatedly exposed to Thai vocabulary. This works particularly well in combination with other learning methods. If you have a smart TV or a Chromecast, you can even play it on your TV instead of regular TV channels. The channel runs 24/7 and replays ThaiPod101 lessons.

Uneed is a platform where people can both discover new products and promote their own. It works a bit like Product Hunt, giving creators a way to get their products noticed. Every day at midnight PST, between 10 and 20 new products launch on the homepage. On launch day, products get prime visibility, but users can keep voting for them anytime afterward. Products are ranked daily, weekly, monthly, and yearly. The top three products in each ranking get badges—gold, silver, or bronze—displayed on their product pages. Popular products also get featured in Uneed’s weekly newsletter, which reaches over 9,100 subscribers. If you want to launch a product, you make an account and fill out the details. There are two ways to get your product live: wait in a free queue (and get assigned a random launch date) or pay $30 to skip the line and pick your date. Success comes from a strong launch day, keeping your page up-to-date, and encouraging people to vote. Adding special deals can also earn you a badge and keep interest alive. The community side of Uneed is built around upvoting products. The more you vote, the more power you gain. For example, a 5-day voting streak doubles your vote’s power, and a 100-day streak triples it while unlocking an avatar border. At 150 days, you get a free line skip; at 500 days, you get discounts on advertising; and at 1,000 days, your votes count as five. The platform covers categories like development, design, marketing, business, and personal life products. It’s just one person running Uneed, and you’re encouraged to vote for your own product. If you have questions, they’re easy to reach via email. In short, Uneed is a straightforward way to launch a product, gather feedback, and build an audience—without needing a massive following upfront.
