Question 1

What files can I upload?

Accepted Answer

SRT, ASS, SSA, VTT, SBV, SUB, SMI, and LRC files are supported.

Question 2

Do I need an account before using AI tools?

Accepted Answer

Yes. AI translation runs start after sign in so credits and files stay tied to your account.

Question 3

Can I use free tools without translating?

Accepted Answer

Yes. Cleaner, timing shifter, and converter are available as utility tools.

Question 4

Is the translation live or queued?

Accepted Answer

Both. Short runs start quickly, but production processing queues work.

Question 5

Can I translate subtitles without uploading a video?

Accepted Answer

Yes. Upload subtitle files directly (SRT, VTT, ASS, etc.). No video upload required — just the text file.

Question 6

What subtitle formats can I translate?

Accepted Answer

SRT, ASS, SSA, VTT, SBV, SUB, SMI, and LRC. The format is detected automatically on upload.

Question 7

How many languages can I translate subtitles into?

Accepted Answer

107+ languages are supported, covering major world languages and many regional ones.

Question 8

Is there a free subtitle translator?

Accepted Answer

Yes. You get 3 free credits on signup — no credit card required. Use them to translate any supported subtitle file.

Question 9

How do I translate SRT files online?

Accepted Answer

Upload your SRT file, select the target language, confirm the run, and download the translated output. The whole process takes seconds.

Question 10

Can I translate multiple subtitle files at once?

Accepted Answer

Yes. Batch processing supports up to 5 files per run, all translated to the same target language.

Question 11

What is a bilingual subtitle file?

Accepted Answer

A bilingual subtitle file displays both the source and target language together in each cue — useful for language learning, review, or multilingual audiences.

Question 12

How accurate is AI subtitle translation?

Accepted Answer

The AI is context-aware and tuned for subtitle phrasing — not literal word-for-word replacement. It handles split sentences, idiomatic expressions, and timing constraints. Review is still recommended before publishing.

Question 13

Is there a quality difference between translation engines?

Accepted Answer

Yes. Basic translation uses a fast engine well-suited for straightforward content. Pro translation runs an advanced multi-pass pipeline that analyzes context, reflects on output, and adapts phrasing. Choose Pro for nuanced scripts, creative content, or when accuracy matters more than speed.

Question 14

Which engine should I use for my project?

Accepted Answer

Use Basic for quick everyday translations, short clips, or simple conversational dialogue. Use Pro for complex scripts, creative writing, technical content, or anything that benefits from deeper language understanding.

Question 15

Will translated subtitles always be perfect?

Accepted Answer

No. AI output is exceptionally fast, but you should still review language quality before publishing.

Question 16

Can I get bilingual SRT and ASS output?

Accepted Answer

Yes. The bilingual tool exports both SRT and styled ASS output on completion.

Question 17

How does the translator handle split sentences?

Accepted Answer

Subtitles often split one sentence across multiple timestamps. The translator groups cues around natural sentence boundaries and keeps each line anchored to its original timing so the translation reads correctly.

Question 18

How are credits calculated?

Accepted Answer

Credits are estimated before the run starts based on subtitle size and density. Basic and Pro tiers use different credit rates.

Question 19

Does Pro translation cost more credits?

Accepted Answer

Yes. Pro uses a higher credit multiplier because it runs a more resource-intensive pipeline. You can see the exact estimate in the model selector before confirming any translation.

Question 20

What happens if a batch gets stuck?

Accepted Answer

Queued jobs can be cancelled manually if stuck, returning credits to your balance.

Question 21

How long do credit packs last?

Accepted Answer

Purchased credit-pack vault credits expire 30 days from the purchase date.

Question 22

How long are translated files kept?

Accepted Answer

Pay-as-you-go access lasts 1 day. Active subscriptions keep files for 7 days.

Question 23

Are files public?

Accepted Answer

No. Files are stored globally securely and are accessed directly through the app.

Question 24

Can I keep editing a subtitle after download?

Accepted Answer

Yes. The account area includes robust preview, edit, and export actions.

Question 25

What does the cleaner actually remove?

Accepted Answer

You can selectively remove SDH notes, speaker labels, leftover HTML formats, and extra whitespace.

Question 26

What formats does the converter support?

Accepted Answer

Convert between SRT, VTT, ASS, SSA, and SBV formats. Input format is detected automatically.

Question 27

Can I extract subtitles from video files?

Accepted Answer

Yes. The extractor pulls embedded subtitle tracks from MP4 and MKV files. No re-encoding needed.
