How to Use Video Chat in HiDownload (Phoenix)

Launch HiDownload (Phoenix). In the main window, click the Video Chat tab next to Download and Sniffer.

In Video Link, paste a YouTube watch URL, then click Analyze. HiDownload fetches captions when available, or uses AI to generate a transcript when the video has none, then prepares the in-app preview.

• Example used in this guide: https://www.youtube.com/watch?v=FwOTs4UxQS4
• You can also paste a local media path, or use Chat with the video from a finished download (see step 6).
• No captions? Analyze still works — AI creates the transcript so you can chat with the video.

When the preview is ready, the player shows the video. Use play / pause / seek, or wait for the transcript list below the player.

When analysis finishes, the Transcript panel lists time-coded lines — from existing captions or from AI-generated text. Use Copy selected or Copy all to reuse them outside the app.

Type a question in Ask about this video… and click Send. While the model thinks, the Chat title shows thinking…. Answers can include timestamps you can click to seek.

• Open Settings (gear) to choose Server AI or your Custom API (Base URL / API Key / Model).
• Server AI needs a HiDownload account / tokens. Custom API uses your own key.

After a download finishes on the Download tab, right-click the task and choose Chat with the video. HiDownload switches to Video Chat, loads that file, reuses sidecar subtitles when available, or generates a transcript with AI when the file has no captions.
