Where it sits in the data

Subtiltee's $1.2K in the last 30 days is higher than 77% of the 5,602 projects with payment-verified revenue in our dataset; the median across them is $150. Within the “Entertainment” category (351 projects) it is higher than 79% (category median $207). Snapshot: 2026-09-02 to 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.

Currency

All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.

Could you build something like this?

In my view, the buyer is a language learner who already watches streaming video and wants practice built around the content they use. Distribution would need to reach those learners through search, communities, affiliates and app-store discovery, while the product would need to support multiple subtitle formats and video platforms.

In my view, the hard parts are extension compatibility, reliable subtitle detection, accurate language explanations, support for different learner levels and the ongoing work of supporting streaming platforms. Privacy, data handling and language-learning claims would also require attention, while competition would come from other language-learning and video-learning products.

Verdict: Needs real work.

One thing to take from it

Subtiltee combines a familiar video surface with language practice tools, including dictation, dual subtitles, translation, dictionary features, grammar breakdown, vocabulary games and rollback. The product's clearest takeaway is a specific workflow for language learners using streaming video.
