SubPool by Diavelin

SubPool gathers subtitles from OpenSubtitles, SubDL, SubSource and Gestdown into a single list and shows, before you pick one, whether it is free or will use one of your OpenSubtitles downloads.

What it does

• One list for all sources. Each entry starts with a tag such as [SubDL] ✓ Free or [OpenSubtitles] Uses 1 download.
• Free subtitles come first; among them, the ones matching your video's release (BluRay / WEB, release group) are on top.
• Works with movies, series and Kitsu anime catalogs.
• Opens ZIP and RAR archives, converts ASS/SSA to SRT and fixes broken Turkish characters.
• 105 subtitle languages; the settings page is available in 11 languages.

New in 3.9

• Dual-language subtitles: your first two languages on screen at once, the first on top, the second below it in italics. They are built only from subtitles that don't use a download.
• Gestdown source: series subtitles from Addic7ed. No account or key needed. It has no subtitles for films.
• Search and download subtitles: for external players. On the settings page, search a movie or series, pick the season and episode, and save the subtitle as an .srt file.

List settings (all optional)

• Use your other languages only as a fallback: the list shows your first language, and moves on to the next one only if nothing is found.
• Hide machine translations.
• Hearing-impaired (HI) subtitles: show, move to the end or hide.
• Remove sound descriptions such as [door slams], ♪ song lines and speaker names.
• "Test my sources" button: checks each connected source with a search only, without using any downloads.

Setup

1. Open the configuration page.
2. Connect at least one source: your OpenSubtitles account, a SubDL API key or a SubSource API key. Or turn on Gestdown, which needs no key.
3. Choose your subtitle languages and their order.
4. Press the install button.

Good to know

• Everyone uses their own account or keys. There is no shared account.
• Your password is not stored on the server. It is kept encrypted inside your personal addon URL, so do not share that URL.
• Viewing the list does not use downloads. A download is used only when you pick a subtitle tagged "Uses 1 download" (a free OpenSubtitles account has 20 per day).
• Existing installs keep working as before; new settings are off until you turn them on.
• The addon is free. Source code is available for review: github.com/MrDiavelin/subpool
