Subtitle AI

Overview

Subtitle AI is a browser-based service for transcribing and translating video subtitles, then editing and exporting them. It suits creators who need multilingual captions and teams handling longer videos or batches of files.

Its strongest case is a flexible workflow: multiple export formats, burned-in captions and speaker-aware editing. The main trade-off is that the free plan is tightly capped, while useful team and production features require higher monthly tiers.

Key features

Transcription and translation support more than 120 languages. Subtitle AI can identify multiple speakers, and its automatic formatting follows CPL, CPS and other industry standards. Those capabilities make it better suited to subtitle production than a basic one-language caption pass, though translation volume on the lower tiers is limited.

Editors can refine subtitles with keyboard shortcuts for navigation, splitting and merging, and apply edits across hundreds of files. Captions can be styled and burned into exported video, or exported as SRT, VTT, EBU-STL, STL, WebVTT, DOCX, TXT, CSV, and JSON/XML. The range of formats is useful when a project needs both subtitle files and review or data formats.

Email support typically replies within 24 hours. Files are retained for one month on all plans, a practical constraint for projects that need longer-term access to source work.

Pricing

All listed plans are billed monthly, and all retain files for one month. The free option is useful for trying real videos without a card, but its €3 credit allowance is one-off rather than monthly; each file is limited to 30 minutes and one translation. Creator raises the duration cap to 60 minutes but keeps the one-translation limit, so it is for solo users who need longer files, not repeated localization. Team is the first tier with unlimited translations and collaboration controls. Pro adds API access and training opt-out for larger workflows, while Enterprise is for organizations that need unlimited seats and a dedicated account manager. Custom pricing applies when a plan has no published price.

Platforms

Subtitle AI runs on the web, so it is an option for browser-based workflows rather than a native desktop or mobile app.

Who it's for

Choose Subtitle AI if you need to subtitle and translate video in many languages, work with multiple speakers, or produce deliverables in several formats. Creators working alone with occasional short videos can start free; solo users with longer files have the $15 a month Creator tier. Teams translating repeatedly or managing revisions will get more from Team or above.

It is less compelling for someone who only needs a free, open-source desktop editor, or whose main requirement is a generous recurring free allowance: the free credits do not renew and translation is capped at one per file.

Pros and cons

• Pros: More than 120 supported languages and speaker handling make it suitable for multilingual, multi-speaker material.
• Pros: Exports include subtitle, document, text, spreadsheet and structured-data formats, plus burned-in video.
• Pros: Keyboard editing and bulk changes support detailed refinement across many files.
• Cons: Free credits are a one-off allowance, with a 30-minute file cap and one translation per file.
• Cons: Creator raises the file limit but not translation allowance; unlimited translations start at $49 a month.
• Cons: One-month file retention applies across every plan.

Alternatives

AI Video Caption Generators is the broader category to browse if Subtitle AI's limits or workflow do not fit.

Zeemo is worth considering for web or mobile use, especially for short clips: its free plan allows 1-minute videos, 200 MB files and exports up to 720p.

Subtitle Edit is the alternative for readers who want a free, open-source subtitle editor on Windows, macOS or Linux.

SRTGen offers web and API access, with free SRT, VTT and TXT export and a 5-minute screen-recording limit.

Translate.Video is another web-based freemium option.

Captions is an option across web, iOS, Android and API.

CaptionFit is another web-based freemium choice.

SubtitleGenerator has a free plan with 60 minutes of subtitle time per month and a 10-minute-per-video cap.

Submagic is a web-based alternative with a Starter plan at $12 a month billed annually, capped at 15 videos per member monthly and two minutes per video.

Verdict

Subtitle AI is a strong fit for creators and teams that need multilingual subtitles, speaker-aware editing and flexible exports in a browser. Its broad language support and production tools are the reason to choose it; the one-off free credits, limited Creator translation allowance and one-month retention are reasons to look elsewhere if recurring free use or longer file storage matters more.
