Common Inquiries

Frequently Asked Questions

Everything you need to know about Lafzi, system compatibility, and licensing.

How is Lafzi different from browser-based caption tools? +

Unlike web tools like CapCut or online SaaS platforms that require uploading massive video files to cloud servers, Lafzi is a 100% native desktop application. It runs locally on your machine's hardware, meaning your raw footage never leaves your computer, rendering is instantaneous, and you never pay recurring monthly cloud fees.

How does Roman transliteration work for South Asian languages? +

Lafzi features a dual-layer neural transliteration pipeline. It transcribes phonetic regional spoken speech (such as conversational Urdu or Hindi) and can instantly transliterate it into clean, readable Latin/English alphabets (e.g., "Aapka swagat hai" or "Apni video ko viral banayein"). You can switch between Native script and Roman script with a single click.

Which machines and operating systems are supported? +

Lafzi is built natively for 3 target environments: macOS Apple Silicon (M1, M2, M3, M4 with Metal GPU acceleration), macOS Intel (x86_64 Core i5/i7/i9), and Windows 10 & 11 (64-bit with DirectML GPU support).

What is the 2-minute limit on the Free edition? +

Lafzi allows video files up to 2 minutes in duration per export—tailor-made for TikToks, Instagram Reels, and YouTube Shorts. For longer formats, interviews, podcasts, and documentaries, Lafzi Studio removes all duration caps completely.

How does the Lafzi Studio license work? +

Lafzi Studio licenses are cryptographically bound to your machine's hardware ID. Once activated with your unique key, your license runs completely offline without requiring continuous phone-home checks, preventing unauthorized account sharing while guaranteeing seamless offline usage.

Can I upload custom fonts like Nastaliq or regional typography? +

Yes! In Lafzi Studio, you can drop in any standard font file (.ttf, .otf, or .woff2). Whether you want classical Urdu Nastaliq (Jameel Noori Nastaliq), Devanagari typography, or modern display fonts, your font renders instantly on your video timeline.

 macOS says "cannot be opened because Apple cannot check it" — How do I allow it? +

Because Lafzi is distributed directly to creators without the Apple App Store middleman, Apple Gatekeeper displays a standard safety notice on the first launch. You only need to allow it once:

Method 1 (System Settings): Open System Settings → Privacy & Security. Scroll down to the Security section. Next to "Lafzi.app was blocked from use...", click the "Open Anyway" button and confirm with your password or Touch ID.

Method 2 (Finder Shortcut): In your Mac Applications folder, Right-Click (or Control-Click) Lafzi.app, choose Open from the menu, and click Open in the verification prompt. Lafzi will launch immediately.
