Frequently asked

How does ViralMint compare to Submagic on pricing?

Yes — ViralMint has an open-source desktop tier that produces word-by-word ASS captions using local FFmpeg + Whisper word-level timestamps, no per-video cost. Heavier AI features (AI script writing, AI voiceover, AI music, AI video clips) are pay-as-you-go via prepaid USD top-ups, no subscription. A Submagic Pro plan is $23/mo; ViralMint's median cost per finished video is around $0.30-1.00 depending on tier.

Can ViralMint produce the same word-by-word captions Submagic is known for?

Yes. ViralMint uses faster-whisper for word-level timestamps and renders captions via ASS subtitle format with three built-in presets: viral (yellow highlight, Montserrat Bold 56pt, 3 words at a time), classic (full sentence, Arial 42pt bottom), bold (green highlight, Impact 64pt, 2 words). The styles are customizable. The caption-burn step is run locally with FFmpeg, no cloud round-trip.

Does ViralMint have a mobile app like Submagic?

No, and that's a deliberate trade-off versus Submagic. ViralMint's features (yt-dlp download, Whisper transcription, FFmpeg pipeline, plus AI chat / image / voice / music) need a real desktop OS — they're CPU-heavy and would burn a phone battery in minutes — so the full studio runs as a free desktop app on macOS/Windows/Linux. The browser at viralmint.net/app is just your account (sign up, balance, top-up). If mobile-first captioning is your top priority, Submagic wins on that single capability — for the broader creator pipeline, ViralMint is the deeper tool.
