Checksub
AI-powered subtitles, translation, and dubbing for global video reach.
A solid all-in-one localization tool for teams needing fast subtitling, translation, and AI dubbing. Its voice cloning and lip-sync (Beta) set it apart, but the credit system gets expensive for heavy usage—Starter's 5 hours/month vanishes quickly. Cheaper alternatives like Descript offer similar core features, while premium tools like Sonix provide enterprise-grade transcription. Best for low-to-moderate volume video creators who value convenience over raw throughput.

Skip Checksub if you need unlimited translations per project (Junior and Starter cap at 1 per project) or if your video volume exceeds 5 hours per month on the Starter plan, as credits run out quickly and Enterprise is pricey.
Going beyond your monthly credit hours (2 on Junior, 5 on Starter) requires upgrading to a higher plan or buying Enterprise custom credits—no pay-as-you-go option.
Checksub’s pricing fits small-to-mid teams with predictable monthly video localization needs—Junior at $18/mo (2 hrs credits) is entry-level for subtitling, while Starter at $59/mo (5 hrs) unlocks dubbing and voice cloning. Compared to Descript (from $12/mo for transcription) and Sonix (from $22/mo), Checksub bundles dubbing and lip-sync, but its credit system makes high-volume use costly. For heavy users, Enterprise (from $299/mo) offers custom credits, API access, and an account manager, but

About Checksub
Checksub is a cloud-based platform that automatically generates subtitles, translations, and AI dubbing for videos, targeting content creators, companies, and organizations. It uses speech-to-text to create subtitles in minutes, with support for translation into 200+ languages. Its AI dubbing replaces original voices while preserving background audio, and voice cloning replicates a speaker's voice in 30 languages. A lip-sync feature (Beta) syncs dubbed audio to mouth movements. The platform also offers animated subtitle styles, burn-in export, and a script-to-subtitle converter. Pricing is credit-based: subtitles use 1 min credit per minute of video, dubbing 3 min credits per minute, and lip-sync 5 min credits per minute. Compared to standalone tools, Checksub bundles subtitling, translation, and dubbing into one workflow, but its credit system can be costly for high-volume users, and there is no free plan beyond a trial.
Behind the Verdict
Checksub is a purpose-built localization platform that bundles subtitles, translation, and dubbing into a single web-based workflow. It stands out with voice cloning in 30 languages and a lip-sync (Beta) feature that syncs dubbed audio to mouth movements—capabilities that require significant engineering and are rarely found in one tool. The platform also offers animated subtitle styles, burn-in export, and script-to-subtitle conversion, which streamline the localization process for non-technical users. However, its credit-based pricing can be a burden for high-volume users: subtitles cost 1 credit per minute, dubbing 3 credits per minute, and lip-sync 5 credits per minute. On the Starter plan, that's just 5 hours of credits per month, which could be consumed quickly if you're dubbing long videos. The Junior plan is cheaper but lacks AI dubbing and voice cloning, limiting its value for those who need those features. Enterprise pricing starts at $299/month (billed yearly) and includes API access, custom credits, and an account manager, which fits larger organizations with predictable workloads. Compared to alternatives, Descript offers simpler editing and transcription at a similar price point, while Sonix provides enterprise-grade transcription but lacks native dubbing and voice cloning. Checksub is best for low-to-moderate volume creators and companies that need a one-stop shop for subtitling, translation, and dubbing, and who value convenience over raw throughput. However, if you have extremely tight budgets or need only basic subtitles, a free or cheaper alternative like YouTube's built-in subtitles or free tools like Kapwing might suffice. Overall, Checksub is a strong choice for teams that want to expand their video reach across languages without hiring voice actors or manual translators.

Real-world workflow fit
Concrete scenarios for the personas Checksub actually fits — and what changes day-one when you adopt it.
You have a new 10-minute video and want to reach Spanish-speaking audiences.
Outcome: You upload the video, enable auto-subtitles (1 min credit), translate to Spanish (1 min credit), and export with burned-in subtitles. In minutes, you have a localized video ready to publish, using just 2 credits from your monthly allowance.
You have 30 minutes of internal training videos and need them dubbed in French and German with a consistent brand voice.
Outcome: You use voice cloning to clone your narrator's voice, then dub each video (3 min credits per minute of video). For 30 minutes, that's 90 credits for dubbing plus translations, which requires at least the Starter plan's 5 hours (300 credits) to cover, ensuring your training content is accessible to global teams.
You need to repurpose a 1-minute product promo into a lip-synced clip for TikTok in 3 languages.
Outcome: You use the lip-sync (Beta) feature (5 min credits per minute) to sync dubbed audio to mouth movements, plus translations (1 min credit each). For 1 minute of video, that's 5 + 3 = 8 credits, which fits within the Starter plan's 5-hour monthly credit pool, allowing you to quickly publish localized clips across
Use Cases
- Automatically subtitle your entire YouTube library in multiple languages to reach global viewers.
- Dub your corporate training videos using AI voice cloning to maintain brand voice consistency.
- Create lip-synced dubbed versions of social media clips for international campaigns.
- Translate and burn subtitles into video ads for targeted markets without manual effort.
- Use the API to build a custom video localization pipeline for e-learning content.
Limitations
- Checksub has several limitations: translation is limited to 1 per project on Junior and Starter plans, which may be restrictive for multi-language projects.
- The credit system can be costly for high-volume use—subtitles cost 1 credit per minute, dubbing 3x, and lip-sync 5x, so a 1-hour video dubbed uses 180 credits (3 hours).
- Unused credits are kept for only 6 months with an active subscription.
- There is no free plan beyond a trial (1 hour of credits).
- The platform is web-based only, with no offline desktop app.
- Lip-sync is in Beta and may not be perfect.
- Voice cloning is available in 30 languages, which may not cover all needed languages.
- The Enterprise plan requires annual billing and starts at $299/month, which may be overkill for small teams.

Setup time & first value
How long it actually takes to get something useful out of Checksub — broken out by persona, not the marketing-page minute.
You can be up and running in under 10 minutes: sign up, upload a video, and auto-subtitles are generated within seconds to minutes depending on length. Translating and exporting takes another 5-10 minutes. For dubbing, allow 15-30 minutes to set up voice cloning and review the output. No credit card needed for the free trial, which includes 1 hour of credits.

Featured Head-to-Head Comparisons
Checksub vs Splice
Splice and Checksub serve completely different needs. Splice is for music producers who need royalty-free samples and rent-to-own plugins, with a new DAW plugin and MCP integration. Checksub is for video creators who need AI-powered subtitles, dubbing, and voice cloning for localization. Choose based on your primary workflow: music production or video localization.
Checksub vs Storyfile
If you need to preserve and interact with real human stories for exhibits or legacies, StoryFile is the only choice—its authentic video recordings and conversational AI create unmatched emotional impact, as seen in museums and CNN's digital twin. But for fast, multilingual video localization (subtitles, dubbing, voice cloning), Checksub is far more practical and scalable. Choose StoryFile for depth of human connection; choose Checksub for breadth of global reach.
Checksub vs Landr Mastering
Landr Mastering and Checksub serve completely different needs: one masters music, the other subtitles/dubs videos. Choose Landr if you're a musician wanting fast, AI-powered mastering; choose Checksub if you're a content creator needing multilingual subtitles or voice cloning. They are not direct competitors, so your decision depends entirely on your workflow—audio vs. video.
