## Pixlr

Pixlr has been one of the best-known browser photo editors for years, and it now wraps a large AI layer around that foundation. Two core editors, Pixlr Express for fast edits and Pixlr Editor for advanced layer-based work, sit alongside an image generator, video generator, audio generator, face swap, collage maker and a long list of one-click retouching tools.

Generation is powered by third-party models, including Flux, Kling, Recraft, Google Veo, Stable Diffusion, Qwen and others, so users can produce images from text, animate stills into video, create music or speech, and then refine everything in the same editor. Tools like Generative Fill, Generative Expand, Generative Transform, Extract Layers and an AI agent that applies natural-language edit instructions make the workflow feel closer to a studio than a simple filter app.

The platform targets both casual creators and businesses with batch editing and template-driven design, and it requires no installation. Pricing is freemium: a capable free tier plus paid plans that unlock more AI credits, higher resolution and advanced features.

**Pricing & Plans:** Freemium with a usable free tier and paid subscriptions that add AI credits, higher resolutions and advanced tools; check pixlr.com for current plan details.

- **AI image and video generation:** Create images from text prompts and turn them into animated video clips using models such as Flux, Kling, Veo and Seedance.
- **Full layer-based photo editor:** Pixlr Editor and Express provide masks, layers, curves, filters and precise retouching alongside the AI tools.
- **One-click AI retouching:** Remove backgrounds, erase objects, swap faces, remove noise, colorize old photos and upscale images up to 25 megapixels.
- **Generative fill and expand:** Select an area or extend an image beyond its frame and let AI fill the gap coherently.
- **Design, collage and batch tools:** Grid-based collages, template designs, layer extraction and batch editing for teams and high-volume workflows.

**Strengths:** Runs entirely in the browser with no installation; Combines a genuinely capable editor with current AI models; Large free tier with no watermark on standard output; Covers images, video, audio, collages and batch workflows in one place

**Limitations:** Heavier AI features consume credits and can require a paid plan; The range of tools can feel overwhelming for first-time users; AI output quality varies by the underlying third-party model

## Polymath

Polymath is built around a simple idea: any large music collection is effectively an untapped sample pack. Instead of digging through folders manually, you point the tool at your audio and let a chain of neural networks label, slice and align it. Music source separation is handled by Demucs, structure segmentation by sf_segmenter, pitch tracking and key detection by Crepe, and audio-to-MIDI by Basic Pitch, with pyrubberband and librosa covering quantization and metadata.

Once a song has been analyzed once, it lives in a local database file, so repeated searches and quantization steps are fast and do not require re-processing. You add tracks with the -a flag (single files, folders or YouTube IDs), quantize with -q against a target BPM or the track's own tempo, and search for similar material with -s. Everything is driven from the terminal or through the included Docker image.

Typical workflows split into two camps. Producers and DJs use Polymath to extract a beat from one genre, a bassline from another and horns from a third, all tempo-matched and ready to drop into a DAW — or to assemble smooth, hour-long mixes from tracks that share a feel. Machine-learning developers use it to generate large, richly labeled audio datasets for training generative music models.

**Pricing & Plans:** Polymath is free and open source under the MIT license. The repository is public on GitHub, so there is no subscription, license fee or account. Running it does require compatible software (ffmpeg and Python 3.7–3.10) and, for practical speeds, a GPU — the cost of any hardware or cloud compute is yours.

- **Library ingestion from disk or YouTube:** Feed Polymath a single track, a folder, or a list of YouTube IDs and it builds a persistent local database of analyzed songs that can be searched instantly afterwards.
- **Neural stem separation:** Demucs splits each song into beats, bass, vocals and other stems, which are then saved to a separated folder for use in your DAW.
- **Tempo quantization to a common grid:** Every track can be time-stretched and re-aligned to a shared tempo and beat grid (for example 120 BPM), so elements from different songs line up cleanly.
- **Structure, key and loudness analysis:** Polymath labels musical sections such as verse and chorus, detects key and loudness, and exposes that metadata for search and filtering.
- **Audio-to-MIDI transcription:** Pitch tracking and Basic Pitch transcription turn melodic material into MIDI files you can edit and re-arrange in any instrument track.
- **Similarity search across the library:** Given a song already in the library, Polymath finds the most similar tracks (optionally including BPM as a criterion) to support mash-ups and long-form mixes.

**Strengths:** Completely free and open source under a permissive MIT license; Chains several proven ML models (Demucs, Crepe, Basic Pitch) into one workflow; Persistent library database makes repeated search and quantization fast; Handles both local files and YouTube sources, plus batch additions

**Limitations:** Python stack is pinned to Python 3.7–3.10, so newer environments may need extra setup work; Requires ffmpeg plus a sizeable set of ML dependencies, and initial GPU support is easiest on native installs; Analysis of every new track takes time before it becomes searchable; There is no hosted web UI — everything runs through the command line or Docker
