SinCap Studio

Winner – Best Sinhala Content Creation Platform of the Year

සිංcap (SinCap Studio) turns your videos into captioned content in Sinhala and English — with the code-switching, word-level timing and natural styling that generic caption apps get wrong.

Pick a video, get an editable transcript, fine-tune the timing and wording, then export a captioned video or subtitle files.

WHAT YOU CAN DO
• Transcribe Sinhala, English and mixed "Singlish" speech
• Word-level timing with clean line breaks and natural pauses
• A full caption editor — edit text, retime, restyle and reposition
• Sinhala and English fonts and rich caption styles
• Burn captions into your video, or export SRT / VTT / ASS subtitle files
• Portrait, square or landscape — the export matches your source
• AI voiceovers, AI script writing and image tools

YOUR OWN GOOGLE AI KEY
The AI features run on your own free Google AI key, which you add once in the app. Before the first upload the app asks your permission to send the audio to Google.

PRIVACY BY DESIGN
Your content stays yours. Your audio is sent to Google for transcription and is never stored on our servers. We keep your account, your subscription status and usage statistics — never your videos, audio, transcripts or captions.

SINCAP PRO
Pro is an optional auto-renewing subscription, monthly or yearly, bought in the app through Google Play. It unlocks every tool and style and raises the limits. Manage or cancel it any time in the Play Store under Payments & subscriptions. Pro belongs to your SinCap account, so it follows you when you sign in on another device.

Made for Sri Lankan creators, editors and social teams who want their Sinhala captions to look right.
