Checksub vs Sonix Comparison 2026
Checksub and Sonix both start at roughly the same price, but they meter different things. Checksub bundles subtitles, translation and dubbing into an annual credit plan, $12 a month billed yearly for 24 hours of credits a year. Sonix transcribes and translates only, with no dubbing at any tier, and offers a real pay-as-you-go rate of $10 an hour with no subscription, alongside monthly plans from $25. Neither has a permanent free tier; Sonix states its trial precisely, at 30 minutes, where Checksub's trial length is not stated.

Checksub
Subtitles, dubbing and voice cloning
Checksub subtitles a video, translates the result and will dub it in a cloned voice with lip sync, which puts the whole localisation sequence behind one credit balance instead of three services. Credits are issued for the year rather than the month, so a batch of back catalogue does not need spreading across quarters. Subtitle files export as SRT and VTT for anybody who wants to burn them in elsewhere. The entry plan carries a watermark and one translation per project, which is the ceiling most people meet first.
Our note
The watermark is the real difference between the two plans, so price Starter as the entry point if the output is going anywhere public. Count your hours across the whole year before choosing, because credits do not reset monthly and a batch of archive footage will eat the Junior allowance in one sitting.
Sonix
Transcription you can pay for by the hour
Sonix will bill by the hour rather than by the month, which is the right shape for somebody who transcribes a batch of interviews twice a year and nothing in between. Accuracy across its 54 languages is good and the editor lines the text up against the audio. Subscribers get storage and an AI workspace that the hourly rate does not include.
Why people weigh these two
- Sonix instead of Checksub
- Sonix transcribes by the hour from $10, a pay-as-you-go path to subtitle files rather than an annual credit pool.
- Checksub instead of Sonix
- Checksub adds dubbing and voice cloning on top of the transcript, starting at $12, for a video that needs to speak another language, not just read one.
Which one should you pick
Choose Checksub if the video needs to come out dubbed, with a cloned voice and lip sync, not just transcribed. That whole pipeline sits behind one annual credit plan starting at $12 a month billed yearly, and Sonix has no equivalent feature at any price.
Choose Sonix if transcription and translation are the whole job and a subscription is not something you want. Pay As You Go is $10 an hour with no monthly commitment, a structure Checksub does not offer at all. Its 54-language coverage and audio-aligned editor suit an interview series transcribed a few times a year rather than every week, and the 30-minute free trial is enough to test accuracy on your own audio before paying anything.
Common questions
- Which one can dub a video?
- Checksub can, with a cloned voice and lip sync from its Starter plan at $48 a month billed yearly. Sonix transcribes and translates text only; its listing does not mention dubbing at any tier.
- Can either be used without a subscription?
- Sonix can: Pay As You Go is $10 an hour with no monthly or annual commitment. Checksub has no such option; even its cheapest plan, Junior at $12 a month, bills as a yearly subscription.
- How long is the free trial on each?
- Sonix states its trial precisely at 30 minutes of audio, with no card required. Checksub offers a free trial too, but its listing does not say how long it runs.
- Which one covers more languages?
- Sonix states 54 languages for transcription and translation. Checksub's listing does not give a language count, so the two are not directly comparable on that number.
