You might like my tool. It has the same general principle as LingQ - learning from content you actually want to read - except it applies it to all web browsing. It's a browser extension that finds sentences in webpages, scores them by difficulty, then translates the ones that are right at the edge of your knowledge.
replyI haven't added Anki integration, though. A few people have asked for it, but it's a big time investment for something relatively niche.
