Catch every error. Fix in one click.
Every correction your team makes can introduce new typos. Run the AI Reviewer as a final pass: it reads every subtitle, catches what humans missed, and catches what their edits broke.
Six things it catches
Grammar
Subject-verb agreement, tense consistency, and syntactic errors checked against target-language rules.
Conjugation
Verb form errors that read naturally but are wrong. Especially critical in French, Spanish, and Portuguese.
Translation
Compares the translation to the original text. Flags mistranslations, omissions, and meaning shifts.
Hesitation
Filler words, false starts, and repetitions left in the text.
Glossary
Checks every subtitle against your project glossary. Brand names, technical terms: always the approved translation.
Punctuation
French and English typography: guillemets and spacing, curly quotes, capitalization, ending punctuation.
One-click fix workflow
Full track read
You start the review: the AI reads every subtitle on the track, in context.

Active AI vs Passive AI
Pasting subtitles into a chatbot works for surface grammar. It misses everything that matters in professional subtitling.
Passive AI
ChatGPT, Claude
- Sees only the pasted text, not the original or the project context. Hard to check a translation.
- Suggestions come as a wall of text, disconnected from your subtitle editor.
- Knows nothing of your glossary or subtitle-specific rules.
Active AI
Hello8 AI Reviewer
- Reads the original text and the translation side by side to catch mistranslations and omissions.
- Comments appear on the exact subtitle. Click to jump, click to apply.
- Checks the project glossary and French and English typography.
