AI subtitles can already reach a high level of accuracy, but they can never be 100% perfect:
Aelano's subtitle editing lets you fix the subtitles in place, into the shape you want — without exporting to another tool, and without having to accept the AI's default result. Once you fix a subtitle the translation follows along and updates, your changes are saved, and the next time you study that content you get the corrected subtitles straight away.
Situations where this fits:
In the player, long-press or right-click a subtitle line and you will see an "Edit" option. Tap it to enter subtitle editing mode.
In edit mode, you can:
Once you are in edit mode, every word can be tapped individually.
Select a word → an edit icon appears → change it to the correct spelling or word.
If a word was missed: select an adjacent word → choose "Add before" or "Add after" → type in what you want to add.
Sometimes a single word gets incorrectly cut into several pieces (compound words, liaison, and so on). Select several adjacent words → tap "Merge selection", and they become one word.
You can only merge adjacent words. To merge non-adjacent ones, delete what is in between first, then merge.
Select a word → delete. This is mostly for words the AI recognized that were never there.
The AI cut a line too finely and it should really be one sentence? Select the two sentences → tap "Merge", and they become one.
A sentence too long, tiring to read, getting in the way of line-by-line study? Tap the position between two words where you want the break, and the sentence splits into two at that point.
If you do not want to tap through every break yourself, you can have the AI re-segment for you. Tap "AI split" and the AI re-cuts the passage at sensible semantic pauses.
Good for: when a whole passage feels badly segmented and you do not want to fix it sentence by sentence.
Every time you save, you will see:
Once the translation update finishes, the new bilingual subtitles take effect.
If you only want to keep the changes to the original text and do not want a re-translation, there is currently no way to turn the automatic re-translation off. If you feel strongly about this, send feedback.
Do my subtitle edits sync across devices?
Yes. Subtitle changes are saved in the cloud and sync across devices.
Will other people see my changes?
No. Changes you make to subtitles in your own library only affect you. Even for a channel you subscribed to from a content source, your edits only change the version you see.
Is there undo or a history?
There is currently no full version history. It is worth double-checking before you make a change, to avoid editing something by mistake.
Can edit mode make bulk changes (replacing every occurrence of a word, for example)?
Right now changes are made one at a time. If a word was misrecognized several times across an episode, you have to fix each occurrence. Bulk replacement is under consideration.
The re-translation is too slow or inaccurate?
If the re-translation does not come out well, you can edit the translation by hand (tap the corresponding translation line to enter editing). Translations you have edited by hand are not overwritten automatically.
Can the subtitle timeline be adjusted?
The timeline follows the original audio and cannot be offset by hand. If subtitles and audio do not line up, it is usually a segmentation problem, which you can solve by merging or splitting sentences, or by having the AI re-segment.
If I make a mess of it, can I restore the AI's original?
There is currently no "restore the AI original" switch. If you edited something wrongly, you can use AI splitting to have the AI re-cut the passage, then adjust by hand.
