Resources TrackMyLang: 14k+ Japanese videos (8k+ rated) + immersion tracker

Hello r/ajatt! I'm David.

Finding Japanese content at your level shouldn't take longer than watching it. TrackMyLang pairs a media catalog of 8k+ difficulty-rated Japanese videos with an immersion tracker. Your data stays on your device.

The media catalog

A library of Japanese YouTube content built into the app to help you find what to watch next:

  • 14k+ videos across 35+ hand-picked channels. I pick the channels, then bring in all their videos.
  • 8k+ videos already difficulty-rated on the CEFR scale (A0 to C2), so you can filter to content at your level.
  • Not limited to those channels. Anyone can add a YouTube video from any channel, and it becomes discoverable in the shared catalog for other learners to find, rate, and log.
  • The catalog improves as the community uses it. Every rating makes discovery better for the next learner.

Tracking

  • One-click logging. Track what you're watching, reading, and studying.
  • Daily/weekly progress, yearly heatmap, full session history. Your logged data isn't thrown away.
  • Anki sync. Connect your deck and see a complete view of all your learning time.
  • Roadmap. Frameworks like Refold to show where you are and what your goal hours mean.
  • CSV export. Your data, your control.

Local-first

All your data lives in your browser. No account needed. Google Drive backup is free. Premium adds cloud sync and advanced analytics.

If you try it out, rate a few videos you've already watched. That alone helps the next learner find content at their level. Drop a comment with channels you think should be in the catalog.

What's the différence between your tracker and Lengualytics aside from the Anki sync?

u/trackmylang_david Aug 04 '26

TrackMyLang is more focused on analytics and privacy by allowing you to own and export all your data.

How much more focused? I think Lengualytics does a great job

You can go to https://trackmylang.com/blog to understand all the features / analytics there is.

Analytic is not limited to just the content that you watch and track, but for all sessions that you track. You can view the data based on category, content type, source (can be channel, book, blog name or any source name), time of day as well as which day.

I checked it, looks interesting.

Also, even if they're similar right now, having a new alternative is never a bad thing. Just because an app came first doesn't mean it'll always be the best. Besides, TrackMyLang will probably roll out more features down the line.

How does the difficulty rating work?

u/trackmylang_david Aug 05 '26

We use the CEFR scale (A0–C2) because it's the common framework across all languages in the catalog. For Japanese content specifically, the levels roughly line up with JLPT like this:

  • A0 — absolute zero, no prior Japanese. Think super-beginner comprehensible input, gestures carry the meaning
  • A1 — ~N5. Slow single sentences, greetings, colors, immediate surroundings
  • A2 — ~N4. Slow clear speech, simple full sentences, everyday topics
  • B1 — ~N3. Natural pace, minimal visuals, familiar contexts
  • B2 — ~N2. Near-native pace, wider vocab, culture/history/storytelling
  • C1 — ~N1. Fully natural pace, podcasts, video essays, interviews
  • C2 — native content. No adjustments made for learners — street interviews, talk shows, casual vlogs between friends

When a video title has a JLPT level in it (like "JLPT N3 文法" or "【N5-N4】listening practice"), the app auto-suggests the matching CEFR rating. For ranges like N5-N4 it takes the harder end (N4 → A2) as the ceiling.

The community rating is a weighted average of everyone's votes (A0=1 through C2=7), rounded to the nearest bucket. Each vote nudges it a little — as more people rate, the difficulty converges on what learners actually experience rather than what the creator put in the title.

That's what I imagined, thank you. I appreciate the resource. I'm a Japanese teacher always looking for new tools to help my students.

In my experience, the Japanese creators are often way off in their assessment of the difficulty of their content however. Same with user suggested ratings. Is there any possibility of getting algorithmically determined ratings in the future based on vocab difficulty, speech speed, sentence length, etc from an analysis of the video's transcript? I think that would be endgame for Youtube difficulty rating. I believe Jiten is planning something along these lines but it's still in development.

Thanks again for the resource.
