## 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

## Notion

Notion started as a flexible document and note-taking tool and has grown into a full AI-native workspace used by individuals, startups, and large enterprises. It lets you build a single system of record where pages, databases, tasks, and wikis live together, then layer Notion AI on top so you can draft, summarize, translate, and query that content without leaving the app.

The platform's newer direction centers on agents and enterprise search. Custom agents can be built to handle recurring workflows — triaging product feedback, resolving support tickets, or automating weekly reporting — while unified search pulls answers from Notion and connected apps with citations. Because everything is stored in the same structured workspace, AI has real context to work from.

Notion is available on web, desktop, and mobile, and there is a generous free tier plus paid plans for individuals, teams, and enterprises. It is widely adopted, with the company reporting over 100 million users across more than 50 countries, and it is frequently used as a company-wide knowledge base and project hub.

**Pricing & Plans:** Freemium model: a free plan covers personal use and small teams, with paid Personal, Team, Business, and Enterprise tiers plus AI add-ons. Larger organizations typically contact sales for custom pricing.

- **Connected workspace:** Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
- **Notion AI assistants and agents:** Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
- **Unified enterprise search:** Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
- **Flexible databases and templates:** Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.
- **Cross-platform apps and integrations:** Work on web, desktop, and mobile, and connect the tools your team already uses through integrations and the public API.

**Strengths:** Very flexible — docs, databases, and project management in one tool; Strong AI features for search, writing, and workflow automation; Generous free plan and broad template ecosystem; Available on web, desktop, and mobile with a mature API

**Limitations:** Flexibility means setup time can be significant for teams; Advanced AI and enterprise features sit on higher-priced tiers; Large workspaces can feel slow or cluttered without good structure
