FAQ

Do I need a paid clipping app?

No. It edits on the bot's own computer with free, open-source tools (ffmpeg for editing, an open-source speech-to-text model for transcripts and captions). No paid apps or API keys needed.

Does it work with videos longer than a minute?

Yes, that's what it's for: podcasts, webinars, live streams and tutorials from a few minutes to a few hours. It works through long files in chunks.

Will it post automatically?

Only after you approve. It schedules approved clips through each platform's official scheduler in your signed-in accounts, or you can set a written standing rule for scheduling clips you've approved.

How is this different from a short-form video producer bot?

A short-form producer makes new videos from scripts, voice and AI clips. This bot repurposes the long videos you already recorded into many short clips.

Will it act without asking me?

No. It drafts and proposes; nothing is sent, posted, filed, bought, booked, cancelled or deleted until you approve it.

Is my data shared anywhere?

No. Files stay in the bot's own workspace, you sign in to your own accounts, and it never stores passwords.
