Capabilities

How Speji works

Like X-ray glasses for foreign languages. Three steps. Zero friction.

Universal Audio Capture

Speji captures audio from any app at the OS level. No integrations needed. TikTok, YouTube Steaming apps, games — it all works.

Real-Time Translation

Our low-latency engine transcribes and translates speech in real-time. See subtitles appear as words are spoken — no delay, no buffering.

Transparent Overlay

Subtitles float transparently over your content. Like the glasswing butterfly it's named after — barely there, beautifully clear.

40+ Languages

From Spanish to Japanese, English to Chinese. Speji supports over 40 languages and we're adding more every month.

Lightning Fast

Built with a proprietary low-latency audio engine that bypasses app-specific APIs. Sub-second from speech to subtitle.

Private & Secure

Audio is processed in real-time and never stored. Your conversations and content stay private. Always.

Our Origin

Where it started

We live in an era of AI abundance. More content than ever before — anime, documentaries, tutorials, memes — created in every language, accessible to anyone with a screen. But understanding it? Still broken.

You're watching an anime and the official translation takes months. You find an educational video on YouTube in Japanese, or a meme on TikTok in Portuguese that's genuinely funny — but you can't fully enjoy it, appreciate it, or share it, because you don't understand the words.

There's no lack of content. There's a barrier. And that barrier doesn't need to exist anymore.

Speji is built on one idea: language should be transparent. Every piece of audio content on your device should be accessible — instantly, privately, without switching apps or waiting for a human translator.

Why "Speji"?

In the rainforests of Central and South America, there lives a creature that defies the rules of nature: the Greta oto, or Glasswing Butterfly.

Unlike other butterflies that use bright colors for camouflage, the Glasswing has evolved a different superpower: Transparency. Its wings are so clear, so free of pigment, that they are almost invisible. In Spanish, they are affectionately called espejitos — or "Little Mirrors."

That's Speji. A transparent layer that sits over your screen — barely there, beautifully clear — and instantly reflects meaning back to you from any audio, in any language.

The Team

Built by people who needed it — for themselves

No product brief, no market research. Just engineers who hit the same wall every day and decided to break it.

Engineers first

We build software for a living. Speji was built the way engineers build things for themselves — precise, minimal, and without unnecessary noise.

Zero interest in your data

We process audio in real-time and discard it immediately. We built Speji because we hate data collection as much as you do. No logs, no training sets, no profiles.

Building something new

There's no shortcut to real-time, on-device audio translation across any app. We built the infrastructure from scratch because what we wanted didn't exist yet.
