The best tool for that kind of thing is developing good note-taking skills. When I'm doing language study, for example, the backbone of my memory reinforcement strategy is a plain old pen-and-paper notebook. Anki is only used for specific, targeted reinforcement. Most my time with Anki these days is learning Chinese characters. That's arguably an ideal use case for brute-forcing with SRS, and that is indeed a very popular way to learn them. But I prefer to start with good note-taking there, too. I keep a notebook where I write down new characters and make some notes about their composition, etymology, and the nature of any relationship they might have with other characters that have a similar appearance or show up as components in this new one. IME even the simple act of physically jotting down a handwritten note to not confuse 买 with 卖 or 找 with 我 is worth some large number of flashcard repetitions all by itself. I also create cards for hanzi in Anki, but typically only after I've already encountered it a few times in my reading and it's starting to feel familiar. Leech cards are a huge waste of time when tackling a large subject, so I don't really like to add a card to my deck until I'm reasonably confident that I won't be hitting the "again" button on it more than once or twice, if ever.
