Two modern AI subtitle translators with overlapping features but different philosophies. Here is what actually separates them in daily use.
Free plan available · No account required
Sublo and Trancy are the closest competitors in the modern subtitle-translator market. Both run as Chrome extensions, both add dual subtitles to streaming services, and both use AI translation. The real differences are setup philosophy, pricing, and how the products feel in daily use.
| Feature | Sublo | Trancy |
|---|---|---|
| Streaming platforms | Netflix, Disney+, HBO Max, Amazon Prime, Apple TV+, Crunchyroll, YouTube + more | Netflix, YouTube, Disney+ and others |
| Translation engine | Gemini AI (fixed) | Multi-engine (configurable) |
| Dual subtitles | Yes | Yes |
| Setup | Install and watch — no config needed | Settings-driven, more options to configure |
| Account required | No | Yes (for Pro) |
| Paid plan | €2.89 / month | ~$5–10 / month |
| Vocabulary / study tools | No — translation focus | Yes — built in |
Zero-config setup. Install Sublo, open Netflix, hit play. The default settings work for nearly everyone. No engine picker, no display toggles to fiddle with, no account to create. Trancy ships with more options because it serves a more configurable workflow — that flexibility is great for power users, but it slows down the first-watch experience.
Lower paid price. Sublo Pro is €2.89 per month (billed yearly). Trancy Pro ranges from $5 to $10 per month depending on the plan. For most people who just want translation to work, that is a meaningful price gap with no functional trade-off.
No account, no friction. Sublo never asks you to create an account. Pro users activate with a license key — that is the entire signup process. Trancy requires registration before you can access paid features.
Tighter Gemini AI integration. Sublo runs exclusively on Gemini, which means the team can tune translation prompts specifically for that model. Trancy's multi-engine approach is more flexible but harder to optimize. In practice both produce excellent results — the engine choice matters less than people expect once both tools are tuned.
Configurability. Trancy gives you control over translation engines, display modes, and learning workflows. If you have specific preferences — a particular translation engine you trust, a specific dual-subtitle layout, custom vocabulary tracking — Trancy lets you set it up your way. Sublo opts for sensible defaults instead.
Built-in study features. Trancy includes vocabulary tools and learning workflows that Sublo deliberately leaves out. Serious language learners who want phrase tracking and study integration inside the extension will find Trancy a better fit.
Pick Sublo if you want the fastest possible setup, the lowest paid price, no account, and a clean translation overlay that just works.
Pick Trancy if you want fine-grained control over translation engines and study features, and you do not mind a slightly heavier setup and price for that flexibility.
If you cannot decide, install Sublo first — the free tier and zero-account flow let you test in under two minutes. If you hit a specific need Sublo does not cover, Trancy is one click away.
Install Sublo for free and try it on Netflix, Disney+, HBO Max, YouTube and more.
Add to Chrome — it's free
Yes. Sublo and Trancy target the same use case — dual subtitles with AI translation across streaming platforms. Sublo focuses on a simpler setup, lower paid price, and Gemini AI translation. Trancy ships more study features and configurable translation engines.
Sublo is built around the streaming-first user: install, watch, done. Trancy targets language learners with more granular controls — engine selection, vocabulary tools, configurable display. If you want minimum setup, choose Sublo. If you want maximum tweakability, choose Trancy.
Yes. Sublo Pro is €2.89 per month billed yearly. Trancy Pro is roughly $5–10 per month depending on the plan.
Both use modern AI engines. Sublo runs exclusively on Gemini AI; Trancy lets you choose between several engines. In practice quality is comparable on most language pairs — the meaningful differences are setup simplicity and pricing, not raw translation quality.
No. Sublo works without any sign-up — install the extension and start watching. Pro users activate with a license key, not a login. Trancy requires creating an account to access paid features.
