Amazing AI vs AudioAlter
Side-by-side comparison · Updated October 2026
| Description | Amazing AI is Sindre Sorhus's free text-to-image app for compatible Apple devices. It runs Stable Diffusion 1.5 locally and is designed around a straightforward prompt-to-image workflow. It is useful for exploring visual ideas without buying cloud generation credits, especially when you want a native app with fewer model and editing choices. It is a fixed-model generator: choose a different workflow if importing LoRAs, editing an existing photo or generating video is central to your project. Describe the subject, composition and visual style in a detailed prompt, then review the generated image. To exclude unwanted elements, the developer documents adding a single ## separator followed by a negative prompt. On macOS you can preview thumbnails, move between images with arrow keys, save with Space and copy with Command+C. Saved images include prompt and generation metadata, which can help organize experiments and reproduce useful settings. The developer also lists batch generation for different prompts, Shortcuts support and automatic upscaling. These are workflow features, not a promise that every output is ready for commercial use. Compatibility is a practical decision point. The current App Store listing requires macOS 26 or later for Mac, and the developer specifies Apple silicon rather than Intel. The iPhone listing requires iOS 26 and an A17 Pro chip or later; the iPad listing requires iPadOS 26 and an M-series or A17 Pro chip. Check the device list in your local App Store before downloading. The model also uses substantial storage and memory, and the first generation may take longer because of model validation. We have not tested speed, battery use or output quality on specific hardware. Amazing AI is free without ads. The developer intentionally does not support custom models, inpainting or outpainting, and the FAQ says the current underlying library produces square images. Draw Things is a relevant alternative when you need imported models, local LoRA training, image-to-image editing or video; Amazing AI's simpler setup can suit people who want to concentrate on text prompts. The developer offers older macOS downloads and a non-App Store version, but says the latter does not receive automatic updates. Use the official download page to check the version and OS requirements. Local generation does not mean that the app never communicates externally. Its privacy statement says it collects no personal information and sends anonymous crash reports to Sentry. Review that distinction before using it in a sensitive workflow. The developer permits commercial and non-commercial use of generated images subject to the Creative ML OpenRAIL-M usage restrictions. That permission does not remove obligations concerning source material, recognizable people, trademarks or other third-party rights. The US App Store listing is rated 18+. Review the final image for artifacts and suitability before incorporating it into a design, presentation or publication. | AudioAlter is an online audio toolkit for changing a file's pitch, tempo, volume or format, reducing background noise, and applying effects such as reverb and stereo panning. It suits a focused edit when you do not need a full multitrack editor. A podcaster might start with Noise Reducer, a musician might transpose a practice track, and a video editor might convert a soundtrack before importing it into an editing project. Start by choosing the tool for the change you need. AudioAlter's help page lists MP3, WAV, FLAC and OGG uploads up to 50 MB. Choose a file, adjust the available controls, submit it for processing, then download and listen to the result. Its browser interface works through server uploads rather than keeping processing entirely on your device. Keep an original copy so you can compare the result and avoid accumulating changes you cannot undo. The Pitch Shifter moves the whole recording up or down by a selected amount, from minus 24 to plus 24 semitones, while maintaining tempo. Twelve semitones equals one octave. This is useful for transposing a practice track, but it is not automatic note-by-note pitch correction or an Auto-Tune replacement. Tempo Changer handles playback speed separately. The toolkit also offers an equalizer, bass booster, trimmer, reverse playback, BPM detection, waveform images and spectrogram images. The slowed-and-reverb and 8D presets combine effects for a particular sound; they do not create new recording rights. AudioAlter's explicitly free Vocal Remover uses OOPS stereo-channel subtraction. It attempts to cancel material shared between the left and right channels, which can reduce a centered vocal. It is different from learned AI source separation: mono recordings, off-center vocals and poor-quality sources may work badly, and centered instruments can disappear along with the voice. Use it for a vocal-reduced practice track and inspect the result before relying on it. AudioStrip is a relevant comparison when you need AI vocal and instrumental separation or a paid batch workflow. Noise Reducer applies automatic general noise reduction for voice recordings without detailed settings. Compare a processed excerpt with the original, checking whether speech remains clear and natural. No hands-on output-quality or speed measurement underlies this listing. For detailed restoration, multitrack editing or repeatable bulk processing, assess a dedicated editor instead; AudioAlter does not document a batch or API workflow here. The terms require users to be at least 16 and to hold the necessary rights to uploaded material. They say processed files are deleted within three hours after upload, sometimes earlier, and the help page says files are accessible through their direct download URLs. Download results promptly and treat those URLs as access to the file. The separate privacy policy identifies Cash Cow IT AB as the owner and data controller and describes analytics and other personal-data retention; the three-hour file rule does not mean every associated record is deleted then. Check project permissions before uploading confidential audio or publishing a processed recording. |
