What's New in Miteiru 8.1.0

Changes since v8.0.1.

AI study tools while you watch

New in this release, all off until you turn them on in Video settings → AI, under While you watch. They use your OpenRouter key.

• Box tips. When the line on screen has a grammar point worth learning, wordplay, a joke, an idiom or a saying, a short card explains it in one sentence. Red marks on the seek bar show where the tips are. A tip stays while you pause, and × hides it.
• AI word splitting (Japanese).
• AI checks where each word begins and ends and adds its meaning in this line.
• Words your dictionaries don't have are saved to Your dictionary and used in later videos too. The word popup marks them Added by AI.
• For Chinese, Cantonese and Vietnamese, it adds missing words to Your dictionary.
• Your dictionary (Video settings → AI → Open your dictionary). Add, edit, search and remove words. Each is labelled AI or You.
• Looks ahead.
• Each request covers 30 seconds or 1 minute of the video.
• Finished parts are kept, so going back costs nothing.
• If an answer can't be used, the tools pause and say so, with Retry. Nothing retries (and charges) by itself.
• Subtitles from the audio (YouTube, Subtitles… → Subtitles from the audio…). Miteiru transcribes the audio just ahead of you in 30-second paid pieces and adds the lines with readings and meanings.
• Spending. Video settings → AI shows what AI has cost on this device, and the top bar shows it while an AI tool is on.

Faster, clearer AI

• Study a text:
• Answers appear as they are written.
• A new question cancels the one still running.
• Asking again reuses the earlier answer.
• No thinking by default. AI tools answer without thinking first, which is faster and cheaper. Let the model think before answering in Video settings → AI turns it on for models that need it.
• Subtitle translation runs three batches at a time, and each batch's English lands on its own lines.
• Readable errors. A failed request says why (a wrong key, for example) instead of "could not parse".

Watching

• Seek bar. Dragging it shows the subtitle at the dragged time while the picture follows.
• Subtitle words line up when only some of them show a meaning or romaji.
• Audio track… (in Subtitles…) switches audio while the video plays, for videos with several tracks.
• Fixes:
• ← near the start of a video no longer jumps to the end.
• The hearing-impaired cleanup removes only a speaker label at the start of a line. It used to cut text before any colon, so "10:30" became "30".
• Next and Previous pick the matching subtitles: ep01.ja.srt, then ep02.ja.srt.
• A subtitle that finishes loading after you switch videos no longer lands on the new one.
• YouTube:
• Captions load in the background while the video starts; choose them from the message or from Subtitles….
• Every link form plays, including /live/ links, music.youtube.com and links without https://.
• Auto-generated captions no longer show every line twice.
• Right-click shows no browser menu over the video. Text fields keep Paste and Copy.
• Missing libmpv. When the video player library is missing, Miteiru says so, with the Linux package names, instead of blaming the file.

Words and study

• My words has a search box (word or meaning) and level chips that filter. It opens at once even with 30,000 words, and keeps your place when words change above you.
• The word popup shows the clicked word's own reading (いる no longer shows as 居る read おる), and saved levels load for every word.
• Flashcards open faster, and say to choose a language when none is loaded.
• Study a text:
• A single line shows in the Sentences list.
• Failed translations say so, and nothing is sent twice while waiting.

Reliability

• Language downloads. A download in progress stays visible after a reload, and Home says correctly when a language is ready.
• Helpers stop with Miteiru. Live captions and other helper programs stop when Miteiru closes or reloads, even after a crash.
• Errors. When something breaks, Miteiru shows what happened with Copy details and Reload Miteiru, instead of a blank "Application error".
• macOS: Command+R reloads again, and the Command shortcuts for translation timing work.

Downloads

• Windows: Miteiru_8.1.0_x64-setup.exe. Install it over 8.0.1; your words, settings and downloaded languages stay.
• macOS (Apple silicon): Miteiru_8.1.0_aarch64.dmg. Still not notarized: open it anyway.
• Linux: Miteiru_8.1.0_amd64.deb and .AppImage, built on Ubuntu 22.04. Video plays through the system's libmpv: the .deb installs it; for the AppImage, install libmpv2 (libmpv1 on Ubuntu 22.04).
• Language packs: Miteiru-language-*.mtrpack. Miteiru downloads these itself; they're here for installing without a connection.
• Updating: 8.1 doesn't update itself. New versions appear on the releases page and at miteiru.hocky.id.
