Audio Duration Calculator
Audio Duration Calculator helps you quickly find the exact length of an audio file so you can plan edits, uploads, and publishing constraints without guessing. You upload an audio file and click Calculate duration to read its duration from media metadata on the backend using FFmpeg’s probe tools. The results are shown as both a readable timecode (minutes/seconds or hours/minutes/seconds for long files) and precise seconds with millisecond-level precision, along with the detected container/format label and file size for context. This is useful when you need to check whether a clip fits a time limit, estimate how much content you recorded, or verify that an export matches the expected length. For users who want quick guidance on what a given length is best suited for, an optional AI Assistant can interpret the duration and suggest practical next steps (such as using it as a short preview or trimming a highlight), while keeping all AI processing on the server.

Audio Metadata Editor
Audio Metadata Editor lets you view and update the most common audio tag fields in one quick upload → edit → download flow. After you upload a file, the tool probes the container and codec, reads existing tags, and displays editable fields such as title, artist, album, album artist, genre, date/year, track number, disc number, and comment. When you click Update metadata, the backend writes your updated tag values into a new MP3 file for consistent playback compatibility and easy sharing. This is helpful when your music library has wrong titles, when podcast exports are missing artist/episode info, or when you want cleaner metadata for car stereos and media players. The tool includes a Sample input button so you can instantly see how tag detection and writing works. For power users, an optional AI Assistant can suggest clean, consistent tag values based on the filename and detected metadata, but it only runs when you explicitly request it and it never changes your file automatically.

Audio Metadata Viewer
Audio Metadata Viewer helps you quickly inspect what’s inside an audio file without opening a full editor. Upload a file and the tool probes technical details such as container format, audio codec, duration, and file size, then extracts common tag fields including title, artist, album, album artist, genre, date/year, track, disc, and comment. This is useful for troubleshooting “Unknown Artist” issues, verifying podcast exports before publishing, checking whether a download actually contains tags, and generating a clean metadata report for clients or archiving. The viewer includes a Sample input button so you can see real tags immediately, and it can export the detected metadata as a JSON report for documentation or workflow automation. For paid users, an optional AI Assistant can summarize missing fields and potential problems (for example, a title that looks like a filename) and suggest conservative tag values based on the filename and existing tags. AI runs only when you request it and is processed securely on the backend.

Meta Description Generator
Meta Description Generator creates optimized snippet candidates for search results from your page title, primary keyword, and summary text. The tool solves a common SEO workflow problem where teams struggle to write concise, click-ready metadata that fits search preview length constraints. You can input a title and summary, choose a tone, include or exclude CTA phrasing, and generate multiple description variants with exact character counts. This supports rapid A/B testing and helps prevent truncated, unfocused snippets. A built-in sample input action demonstrates best-practice formatting instantly for new users. For premium workflows, an optional AI Assistant analyzes generated variants and provides optimization actions with testing ideas based on keyword placement and search intent fit. All actions are explicit and user-triggered, making the tool practical for editors, marketers, and technical SEO teams managing high-volume pages.

Podcast Recorder
Podcast Recorder helps you capture a complete podcast-ready episode in a simple browser flow: record your main audio, optionally add an intro clip and outro clip, and export a single stitched MP3 you can share anywhere. The tool uses your browser’s microphone recording for the main take, then sends your audio parts to a public backend endpoint powered by FFmpeg to concatenate the clips and encode a consistent MP3 output. You can also set optional MP3 metadata (title, artist, album, year, genre, and a short comment) so the exported file is labeled cleanly in players and file managers. A Sample Input button loads real audio clips so you can test the full record → stitch → download pipeline without touching your microphone. For creators who want a faster publishing workflow, an optional AI Assistant (runs only when you click) can turn your outline into structured show notes, chapters, and hashtags.

SEO Title Generator
SEO Title Generator creates multiple search-friendly title options from your topic and primary keyword so you can publish faster and improve click-through potential. You provide a topic, keyword, audience context, and intent, then generate title variants with character lengths optimized for common SERP display constraints. The tool addresses a common SEO challenge: writing concise, relevant titles that include target terms without sounding repetitive or being truncated in results. It supports rapid editorial iteration by presenting several options in one pass and exposing exact lengths for each title. A sample input action helps users validate output style instantly. For premium users, an optional AI Assistant provides title optimization guidance based on length, keyword placement, and test strategy so teams can run structured CTR experiments while keeping messaging aligned with search intent.

Video Metadata Editor
Video Metadata Editor is a streamlined utility for fixing and updating common metadata tags inside a video file. Upload a video and the tool probes the container and video stream, then reads existing metadata such as title, artist/creator, genre, year/date, and a description-like comment. You can edit these fields directly in the browser, preview the detected file information, and then click Update metadata to export an updated MP4 that includes your new tag values. The backend writes metadata using FFmpeg in a deterministic, stateless request so processing is fast and the UI stays responsive. If direct stream remuxing is not possible, it falls back to a safe MP4 export path for compatibility. An optional AI Assistant can suggest consistent tag values using the filename and detected tags; AI only suggests and nothing is applied until you explicitly update metadata.

YouTube Hashtag Generator
YouTube Hashtag Generator creates hashtag sets for video metadata based on your topic, target keywords, and audience. Instead of manually brainstorming tags, you can generate a curated hashtag list in one step and adjust count based on your publishing strategy. The tool is useful for creators who need faster upload workflows while maintaining topical relevance. It transforms plain keyword input into hashtag-ready tokens, deduplicates overlaps, and returns clean output suitable for descriptions and shorts captions. A sample input action helps new users understand expected formatting instantly. For premium users, an optional AI Assistant suggests optimization strategy for hashtag mix quality, balancing broad discovery tags with niche intent-specific tags. All processing is explicit and user-triggered, making the tool reliable for repeat content publishing workflows.
