The classic side of the product covers the essentials most people need every day: viewing and editing PDF text and images, converting between PDF and Office/image formats, OCR for scanned files, merging, splitting, compressing, watermarking, signing and annotating. Because everything runs in the browser with companion apps for Windows, Mac, iOS and Android, the same account and files travel with you across devices. The AI layer is where the product has expanded most. An AI agent lets you chat with an uploaded document, ask follow-up questions and trace answers back to citations, while a separate chat experience works on YouTube videos. Document translation preserves the original layout across 20+ languages, including scanned and image-based PDFs, and structured data extraction turns invoices, receipts, bank statements and purchase orders into editable spreadsheets. Rounding out the suite are an AI PPT generator, mind-map and summary generation, watermark and sticker removal, text and logo erasing, document enhancement for scanned pages and an AI invoice generator. Pricing follows a freemium model with a free tier (10MB file limit, watermark on some exports) and paid plans that add unlimited file sizes, batch processing, cloud storage and monthly AI credits. Individual subscriptions start around $5.99 per month, with a yearly option near $15.99 and a one-time lifetime plan; credits are consumed per AI action, so heavy AI users can top them up. Team, business and education plans are available on request. **Pricing & Plans:** Freemium.

You import a video by direct upload, YouTube link, or by connecting your YouTube account, and the platform transcribes and translates it into your chosen language. The dub is generated with natural, human-sounding AI voices, and the resulting video can be exported with dubbed audio plus optional subtitles or an SRT file. The editor is where the product does much of its work. Every clip can be re-translated by editing the source text and regenerated to get a different read, so you can iterate on a line until it sounds right. You can switch languages mid-edit to compare dubs against the original, click the timeline to seek or a segment to play it, add new speakers and give each a distinct voice, assign speakers across segments, and use bulk re-translate and regenerate actions when many segments go stale. Auto-save keeps edits from being lost, and a cost summary estimates charges before bulk operations. TransDub supports speaker identification for up to 10 speakers on paid usage, which suits podcasts and interviews where several people talk. It also lets creators connect multiple YouTube channels so each localized version is published to the right language-specific channel. The pitch is cost: the site compares a traditional studio-plus-voice-artist workflow costing roughly $2,000 per video against TransDub's usage-based pricing, which starts at $49 per month. **Pricing & Plans:** TransDub is freemium with usage-based pricing. The Free plan costs $0 with no credit card required and includes 1 minute, up to 2 speakers, and a 1-week credit expiry. The Pro plan starts at $49 per 30 minutes of usage, supports up to 10 speakers, keeps credits for 90 days, and includes export without watermark plus direct YouTube publishing. - **AI dubbing in 70+ languages:** Translate and dub a single source video into more than 70 languages with natural, human-like AI voices drawn from a library of 10,000+ voices. - **Full editor control:** Re-translate any clip by editing the source text, regenerate for a different read, switch languages mid-edit, seek on the timeline, and run bulk re-translate or regenerate actions. - **Speaker identification:** Detect multiple speakers automatically and assign each a distinct voice — up to 10 speakers on paid usage, 2 on the free plan. - **Captions and SRT export:** Export the dubbed video with subtitles or download translated transcripts as SRT files for use elsewhere. - **Direct YouTube workflow:** Import via a YouTube link or connected account and publish dubbed versions straight to YouTube, including separate channels per language. **Strengths:** Covers 70+ languages with natural-sounding AI voices backed by a large voice library; Editor supports per-clip corrections, language switching, and bulk regeneration; Speaker identification makes multi-voice podcasts and interviews sound natural; Transparent usage-based pricing and direct YouTube publishing, including per-language channels **Limitations:** Usage is metered by minutes, so long videos and many languages add up quickly; The free plan is limited to 1 minute and 2 speakers, enough only for testing; Credits on paid plans expire after 90 days, which requires planning ahead [Profile (Markdown)](https://openaitools.app/tool/transdub.md) ## Frequently Asked Questions ### How do LightPDF and TransDub compare in monthly traffic?
