I use British English more than my native English, and it’s great that I have always been able to say and hear my ideas.

I was lucky to learn my vocabulary in a systematic way (watching lots of American shows/ movies, talking to people online) so I now have a lot of random gaps in my vocabulary that would probably make even middle schoolers laugh at me (I’m exaggerating, but you get the idea).

In the system I bought a 4K word flash card which I used for a long time but really didn’t have enough RAM to fit it fully in my wallet, this time I started using a flash card I found in Anki databases. A few weeks ago I decided to put an end to it, and started with a 2k word flash card I found in Antnap. Only 1 out of 20-30 words is somewhat unclear to me, the rest is just “next, please” (I’m in my 90’s)” I thought about picking some other set, with “advanced” words or something like that, but that’s not really what I’m looking for, since I’m missing relative many basic words, which everybody knows, like, say, body parts, or sickness symptom names, etc.

What I need is a piece of software which would test my vocabulary and detect the gaps for me + help me fill them, instead of me doing a thorough research instead, and building a custom flash card set. Does something like that exist, or should I stop dreaming and carry on with Anki?

Can I go analogue to a friend and her website?
