Douyin Toolkit

Description

Player controls, video info, user-initiated downloads, and local history & playlists for douyin.com. Local-first, no tracking. Douyin Toolkit makes watching and researching douyin.com more controllable — without changing how the native site works, and without sending your data anywhere. Everything runs locally in your browser: no account, no sign-up, no tracking, no cloud. ▶ PLAYER CONTROLS • Playback speed 0.25×–4× with presets, and it reapplies your speed when Douyin resets it • Volume boost up to 200% with a safety limiter, plus an optional normalizer • Picture-in-picture, rotate, zoom & pan, and a screenshot of the current frame • Auto-pause / auto-resume and a background-play preference • Cinema mode to hide everything except the video, with a hold-to-peek key • Per-element hide switches: hide the engagement rail, captions, comments, top nav, recommendations or player controls — instantly • Auto-next: reuses Douyin's own Autoplay when available, with a fallback for pages that lack it • Configurable keyboard shortcuts with conflict checking ℹ VIDEO INFORMATION • Normalized public info: author, caption, hashtags, music, duration, publish date • Real public metrics: likes, comments, shares and favorites (Douyin's web platform does not publish view counts, so views show "—") • One-click copy: link, caption, hashtags, or JSON ⬇ DOWNLOADS (always user-initiated) • Save the video you are watching — best quality or best-effort watermark-free, whichever the page already exposes • Download the audio track, save a metadata JSON, or capture a screenshot • Honest labels: the actual audio format and watermark confidence are shown, never faked • Collision-safe filenames, naming and folder templates 📚 LOCAL LIBRARY • Watch history with watch time, search, filters and retention controls • Local playlists (unrelated to your Douyin favorites) • Import/export your settings; delete all local data at any time 🔎 CREATOR RESEARCH (opt-in) • Capture the items a profile tab has already loaded, filter them (type, min likes, date, keyword), and bulk-download a selection • Deterministic analytics: totals, averages, medians, engagement, upload frequency, top posts, trends, hashtag & music usage • Immutable snapshots and creator-to-creator comparison that warns when scopes differ • Export to CSV, JSON or XLSX; export public comments (public fields only) 📡 LIVE (research) • Detect a public live room and its stream variants • User-initiated FLV recording via Chrome downloads, with elapsed time and bytes shown • Export room metadata — never chat, credentials or private data 🔒 PRIVACY BY DESIGN • Local-first: settings, history, playlists and analytics stay in your browser • No accounts, no telemetry, no third-party cloud • It never collects or transmits your cookies, passwords, session tokens, or browsing history • All code is packaged in the extension — nothing is loaded or executed remotely • Works only on douyin.com and live.douyin.com You are responsible for respecting content rights, consent, platform terms and local law. Downloads are always started by you. If Douyin shows a login, rate-limit or verification challenge, the extension pauses and lets you resolve it in the page.
