Transcript in. Social posts out.
Drop in a transcript from your video or podcast. LuniSpark helps you pick the highlight moments and drafts Facebook, LinkedIn and X posts from the exact words in your transcript — every quote stays traceable to its timestamp.

Honest status: this beta picks highlights with transparent rules and your own selections — it does not call any AI service. Our local, on-device AI (LuniSpirit) is in development and will plug into this same page when it is ready.

SRT, WebVTT or plain text (.srt / .vtt / .txt), up to 1 MB. Your file is read on this device only and lives in memory — reloading the page clears it.

How LuniSpark protects your words
- Quotes are never invented. A quote renders only from a real cue in your transcript, with its timestamp.
- Nothing leaves your device. No upload, no analytics on your content, no AI service calls — the AI budget of this product is $0 by design.
- Draft-only. You copy and post yourself; there is no “connect account” button anywhere.
- Coming next: LuniSpirit, our local AI, will choose highlights on-device — same page, same rules, still $0.
