## 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

## SpicyChat AI

SpicyChat AI has carved out a distinct position in the uncensored AI companion space by rejecting unpredictable coin and token microtransactions in favor of transparent, flat-rate monthly tiers. Operated by Montreal-based NextDay AI Incorporated, the platform hosts nearly one million user-created chatbots spanning fantasy RPGs, romance, sci-fi, and adult roleplay. Even on the free tier, users can create unlimited characters and chat with a 4,096-token context window (recently upgraded to a 26B base model), provided they are willing to tolerate banner ads, waiting queues during peak hours, and a 180-token reply length cap.

Following a platform-wide pricing update on September 8, 2026, SpicyChat structures its paid upgrades around context memory, model sophistication, and multimodal extras rather than message meters. The entry-level Get A Taste plan ($5.95/month) strips out ads, bypasses waiting lines, unlocks the manual Memory Manager, and supports up to 10 user personas. Stepping up to True Supporter ($19.95/month) doubles the context window to 8,192 tokens, activates automated Semantic Memory 2.0, raises maximum reply length to 300 tokens, unlocks unlimited in-chat image generation on supported bots, and expands persona slots to 50. At the top tier, I'm All In ($29.95/month) pushes context up to 16K–32K tokens across premier models—including SpicyXL, Qwen Plus Character, GLAM 5.1, and DeepSeek V4 Pro—while adding unlimited Text-to-Speech (TTS) voice replies and 100 user personas.

Beyond individual chats, SpicyChat emphasizes worldbuilding and multi-character dynamics. Creators and players can attach structured Lorebooks to inject world history or faction rules dynamically when keywords surface in conversation, or launch Group Chats where multiple AI personalities interact using smart auto-responses. While users still note that editing or deleting a chat message requires manually updating the Memory Manager to prevent stale recall, SpicyChat's predictable all-you-can-use billing makes it a favorite for heavy daily roleplayers.

**Pricing & Plans:** Offers an ad-supported Free tier (4K token context, up to 180-token replies, and waiting queues) alongside three flat-rate subscriptions updated on September 8, 2026: Get A Taste ($5.95/mo or $60/yr), True Supporter ($19.95/mo or $199.95/yr for 8K context, Semantic Memory 2.0, and in-chat images), and I'm All In ($29.95/mo or $299.95/yr for up to 32K context on select models, SpicyXL, and text-to-speech).

- **Curated Multi-Model Switcher (Up to 32K Context):** Lets paid users switch between specialized roleplay LLMs—including SpicyXL, DeepSeek V4 Pro, DeepSeek V3 XTC, Qwen Plus Character, and GLAM 5.1—with context windows scaling from 4K (Free) to 8K (True Supporter) and up to 32K (I'm All In).
- **Semantic Memory 2.0 & Manual Memory Manager:** Combines manual memory pinning and editing (available from $5.95/mo) with automated Semantic Memory 2.0 vector recall on True Supporter and higher tiers to retain long-term relationship facts.
- **Flat-Rate In-Chat Image Generation & TTS Voice:** Generates unlimited contextual conversation images on True Supporter ($19.95/mo) and private/all chatbots plus unlimited Text-to-Speech character audio on I'm All In ($29.95/mo) without charging per-action tokens.
- **Lorebooks & Multi-Bot Group Chats:** Supports attachable Lorebooks for keyword-triggered worldbuilding alongside multi-character Group Chats powered by Smart Auto-Responses.
- **Up to 100 Customizable User Personas:** Allows roleplayers to maintain distinct names, physical descriptions, and backstories across different storylines—scaling from 10 personas on Get A Taste to 50 on True Supporter and 100 on I'm All In.

**Strengths:** Flat-rate subscription pricing with zero token or coin microtransactions for messages, images, or voice; Wide selection of specialized roleplay LLMs including DeepSeek V4 Pro, Qwen Plus Character, GLAM 5.1, and SpicyXL; Rich worldbuilding ecosystem featuring Lorebooks, multi-bot Group Chats, and up to 100 user personas; Grandfathered pricing protection for recurring subscribers who joined prior to the September 2026 rate adjustment

**Limitations:** September 8, 2026 price increase raised new monthly subscriptions by 19% to 33% ($5.95, $19.95, and $29.95/mo); Free and entry-level Get A Taste tiers are capped at a modest 4,096-token context window and 180-token reply lengths; Deleting or editing chat messages does not automatically purge saved entries in the Memory Manager, requiring manual cleanup
