Comparison

Sokuji alternative: open-source vs hosted
Two-way desktop speech translation — fair comparison.

Sokuji is the closest open-source neighbour to a paid desktop simultaneous interpreter. Parley is a commercial hosted desktop app. Neither replaces the other for every user.

In short: Sokuji is open-source real-time two-way speech translation (desktop on Windows, macOS and Linux, plus a Chrome/Edge extension). It can run with cloud providers when you bring your own API key, or fully offline on-device; translated audio goes into any app microphone, including Zoom, Meet and Teams. Parley is a commercial desktop app: hosted Qwen and Doubao, prepaid per session-minute, and the other people need not install anything. If you want to bring your own key, run local models and accept AGPL-3.0, Sokuji is a strong choice. If you want zero-config hosted translation and a per-minute wallet, Parley fits. Neither product is a unique option. (Disclosure: we make Parley.)

How Parley billing works

Managed translation needs wallet credit. One connected session covers both directions — speaking and listening share a single charge — and billing includes silence while the session is connected, so stop the session when you are done. Qwen is $0.070/minute and Doubao is $0.148/minute; a $1 first top-up trial is available. Only Qwen and Doubao are live today; OpenAI and Gemini are Coming soon. Ear return is on by default at about a 15% mix and can be turned down or off. Venue interpretation needs a separate venue licence. Windows installers are currently unsigned, so Windows may warn about an unknown publisher. See pricing and FAQ.

Setup

This page does not include click-by-click setup for Sokuji or Parley. For Sokuji, follow the project README and sokuji.kizuna.ai. For Parley, the app appears as a microphone and speaker path for mainstream meeting software on Windows and Mac — exact menus differ by OS and client version, so follow the download and audio checklist and test both directions before a real call.

Questions

Is Sokuji a good Parley alternative (and the other way around)?

Yes, for many overlapping bilingual-meeting jobs — both can put translated speech into a meeting microphone so the other people need not install anything. They differ on licence (AGPL vs commercial), offline capability, whether you must bring your own API key, platforms (Sokuji includes Linux and a browser extension), and billing (provider/self-host vs Parley’s prepaid per-minute wallet). Choose by those priorities; neither product is a unique desktop two-way option.

Do I need to bring my own API key with Sokuji?

Not for the local on-device path: Sokuji’s README documents fully offline inference without an API key. For cloud models you bring your own key for the providers listed in the Sokuji README (checked 2026-10-15), or you can use the optional Kizuna AI account that holds a key and meters usage. Parley’s managed Qwen and Doubao path does not require your own key; OpenAI and Gemini are coming soon on Parley’s managed list, and an optional personal API licence exists if you prefer your own keys.

Can Sokuji run fully offline?

Yes. The repository and product site present on-device ASR, translation and text-to-speech as a first-class path — no key and no internet for that mode. Quality and resource use depend on the local models you download. Parley’s managed translation needs a network connection and sign-in.

Do the other participants need to install anything?

With either tool in the usual virtual-microphone meeting setup, no. You run the desktop app (or Sokuji’s extension on supported sites); the other people stay in their meeting app and hear ordinary call audio. Confirm current Sokuji extension site support on the Sokuji site.

When should I pick Sokuji over Parley?

Pick Sokuji when open source, AGPL, offline inference, Linux, a browser extension, or bring-your-own keys matter most. Pick Parley when you want hosted Qwen/Doubao without configuring providers first, a published per-minute wallet, and a Windows/Mac commercial installer with ear return at about 15% by default. Many people evaluate both; that is expected.
