seadanceai-transcript-sdk (Python)

PyPI Python License Sponsored by Seedance AI

Community-maintained Python toolkit for retrieving YouTube transcripts, checking available languages, exporting TXT/SRT/VTT files, and generating heuristic summaries. Proudly sponsored by Seedance AI.

✨ Features

  • Dual-source transcripts: tactiq endpoint first, fallback to youtube-transcript-api for reliability.
  • Language probing: batch-check common caption languages.
  • Formatters: output transcripts as TXT/SRT/VTT with helper functions.
  • Summary helpers: generate concise recaps + key points without external APIs.
  • Zero external API keys required; just Python + HTTP.

📦 Installation

pip install seadanceai-transcript-sdk

⚡ Quick Start

from seadance_transcript_sdk import TranscriptClient, format_transcript_file

client = TranscriptClient(enable_fallback=True)
transcript = client.get_transcript("dQw4w9WgXcQ", language="en")
file_payload = format_transcript_file(transcript, fmt="srt")
with open(file_payload.filename, "w", encoding="utf-8") as fh:
    fh.write(file_payload.content)

More helpers:

from seadance_transcript_sdk import detect_available_languages

langs = detect_available_languages("dQw4w9WgXcQ")
print([lang.name for lang in langs.languages])

summary = client.summarize(transcript)
print(summary.summary)

🧩 Modules

  • seadance_transcript_sdk.transcript – fetch logic + language probing.
  • seadance_transcript_sdk.formatting – TXT/SRT/VTT helpers.
  • seadance_transcript_sdk.summary – heuristic summary utilities.
  • seadance_transcript_sdk.client – ergonomic wrapper with sensible defaults.
