Audjust AI

The homepage describes the core editing flow in three steps. First, you drag and drop an audio file or paste a URL into the editor. You can explore the site and the editor without an account, and are asked to sign in only when you run an analysis, generate, or export.

Second, you choose the job. The AI Audio Editor offers Shorten Song, Lengthen Song and Find Loops modes, and the upload and analysis area switches to the selected mode. A Basic Analysis costs 10 credits and an Advanced Analysis 50 credits; in the extender, a basic preview is free and an optional Advanced Extender adds 10 credits. A separate Direct AI Transform section starts jobs immediately for vocal removal, stem separation, audio-to-MIDI conversion and Lo-Fi conversion.

Third, you preview and download the result, which is saved to My Audios in your workspace so you can come back to it later. From a finished result the interface offers shortcuts to shorten it to an exact length, extend it, turn it into a clean loop, or separate vocals and instrumental.

For video work, the Make Music Fit Video page takes an MP3 and a target of 15, 30 or 60 seconds or a custom length between 5 and 600 seconds, or builds a pack of all three versions at once. It shortens longer tracks automatically and uses a repeat-ready section when the source has to be extended. Each version costs 20 credits, and failed outputs are refunded. If you have no track to start from, the AI Music Generator takes a written description or lyrics, lets you pick a model and controls, and generates a track you can preview, download and then edit in the same workspace.

• •Smart Song Shortening and Lengthening - The central feature changes a track's duration while preserving its structure. The site's examples include cutting a 3:45 song to 2:30 for TikTok while keeping the chorus and bridge, and stretching a 2:15 track to 3:30. Lengthening works by identifying natural loop points and musical patterns, so a background bed can run under a longer narration, reel, course or product demo instead of stopping early. Shortening looks for cleaner edit points so the result ends naturally rather than being chopped or faded out.
• •AI Loop Detection - Find Loops scans the whole track, analyses patterns and transitions, and surfaces seamless loop ranges you can preview instantly, such as an 8-bar hip-hop section or a chorus loop. The site positions it for producers building samples, DJs preparing sets and creators who need a clean repeating segment rather than a brand-new song. A related song analyzer reports BPM, section flow and repeat-ready ranges and turns them into a prompt scaffold for later generation.
• •Make Music Fit Video - A dedicated timing tool for 15-second ads, 30-second reels, YouTube intros and podcast beds. You can read the target duration from a video file, which the page says stays on your device, and choose a single length or a 15s, 30s and 60s version pack. Output is audio only, ready to drop back into an editing timeline.
• •AI Music Generator - Text-to-music generation with a choice of models from the AUDjUST V-Series, a prompt of up to 500 characters in the default mode, an Instrumental Only switch, a preferred length setting, and a custom mode for lyrics, title and style where the model supports it. A generation shows its credit cost before you run it (20 credits in the default setup). The pricing page lists text, lyrics and image-to-music generation as part of the Pro plan, and prompts must not name real artists or bands.
• •Stem Separation and Direct Transforms - Remove vocals, bass or drums from a song and receive two downloadable files per job: the remaining mix and the isolated stem. The first successful separation costs 8 credits and later ones 20. The same toolset includes a karaoke maker, an acapella extractor, audio-to-MIDI conversion with a MIDI editor and key and BPM tools, a Lo-Fi converter, and batch processing for several files.
• •Release Visuals and Music Videos - A Music Release Pack collects a music visualizer, a Spotify Canvas maker, a lyric video maker and an AI music video generator. Each account gets one shared free 15-second AI video trial with an audjust.ai watermark; paid video generation requires an active Pro or Premium subscription and is charged in credits per quote, starting at 50 credits.

Audjust AI is aimed first at short-form video editors and social creators who need music to land exactly on a cut: TikTok, Instagram Reels, YouTube Shorts and branded videos where a track has to be 15, 30 or 60 seconds long and still end cleanly. YouTubers and podcasters can use it to trim or extend intro and outro music and to stretch background beds under narration without reopening a full DAW session.

Musicians and producers will find the loop detection, stem separation, acapella extraction and audio-to-MIDI tools useful for sampling, remix preparation and beat-making, with exports that can move into DAWs such as FL Studio, Ableton or Logic Pro. Marketing and brand teams, along with agencies delivering client edits, can produce several timed versions of the same music bed for ads, product demos and campaign cuts; the Premium plan is pitched at teams handling batch options and multi-project work.

Creators without a suitable track can generate original instrumental or vocal music from a description or lyrics and then edit it in the same place. Paid plans add private creation, watermark-free exports and commercial use for Audjust-generated music. The site is explicit that this does not extend to uploaded material: if you edit an existing song you still need the rights to it, because Audjust adjusts timing and structure but does not clear third-party music rights. The free tier, with starter credits and a small daily check-in bonus, is enough to try the editor on a few files before choosing a plan.
