## JanitorAI

JanitorAI has evolved from an early bring-your-own-key chatbot directory into one of the largest independent roleplay ecosystems on the web. Rather than locking users into a single rigid model, the platform runs its own proprietary model family—JanitorLLM (JLLM), including the conversational JLLM-short variant that trims reply length by roughly 70%—for free to registered users. At the same time, power users can connect external API keys, reverse proxies, OpenRouter endpoints, or local LLM backends, complete with a redesigned proxy manager that supports drag-and-drop config reordering and reasoning 'thinking box' tags.

In mid-2026, JanitorAI introduced its first first-party monetization layer without restricting its free baseline: Janitor+ ($12.99/month) and the web-based Janitor+ Router. While standard users keep unlimited free messaging with around 9,000 tokens of context, Janitor+ subscribers gain 5x expanded context memory, priority queue placement during peak hours, and 300 enhanced monthly regeneration swipes powered by frontier models. Through the Janitor+ Router, subscribers can also fund an integrated per-token wallet to switch between third-party commercial LLMs directly inside JanitorAI with transparent per-token pricing and a 10% subscriber discount—eliminating the need to configure external proxy URLs.

For bot creators, JanitorAI offers deep technical customization rarely seen on mobile-first companion apps. Character definitions support payloads up to 1 MB, multiple initial greeting messages, and a dedicated Scripts engine that injects conditional logic and whole-word triggers so bots react deterministically to story state changes rather than relying on prompt compliance alone. Combined with granular generation rules—such as forbidden word lists, custom Top-K/Top-P sliders, repetition penalties, response prefill, and custom profile CSS—JanitorAI caters heavily to long-form writers and technical roleplayers.

**Pricing & Plans:** Core access to JanitorLLM (with ~9K token context and unlimited chats) and bring-your-own-key (BYOK) proxies remains completely free. The optional Janitor+ subscription launched in June 2026 at $12.99/month, adding 5x context memory, unlimited priority messages, 300 monthly frontier-model enhanced swipes, and access to the per-token Janitor+ Router wallet (with a 10% discount on popular third-party models).

- **Free JanitorLLM & JLLM-Short Engine:** Provides unlimited free character chats powered by JanitorAI's in-house LLM (~9K context window on free accounts), with a toggleable JLLM-short mode for snappy, dialogue-focused replies that are 70% shorter.
- **Janitor+ Router & Multi-Proxy Manager:** Lets Janitor+ subscribers tap directly into third-party frontier models via a built-in per-token wallet at a 10% discount, while keeping full BYOK reverse-proxy support with config duplication and reasoning tag display.
- **Conditional Character Scripts & 1MB Definitions:** Allows creators to build complex characters up to 1 MB in size with multiple intro scenarios and programmable Scripts that trigger dynamic lore or behavioral rules using whole-word matching and built-in debugging tools.
- **Granular LLM Generation Controls:** Exposes low-level sampling parameters in the chat menu, including custom Top-K, Top-P, frequency and repetition penalties, forbidden vocabulary lists, and response prefill instructions.
- **Custom CSS Profiles & Chat Typography:** Features an interactive CSS editor with guided tutorials for styling creator profiles and character cards, alongside per-chat text settings to customize fonts, italics styling, and accent colors.

**Strengths:** Core JanitorLLM chat experience remains genuinely free with unlimited messages and ~9K context tokens; Supports both one-click built-in third-party model routing (Janitor+ Router) and full BYOK custom proxies; Industry-leading creator toolkit featuring 1 MB character limits, conditional Scripts, and forbidden-word controls; Transparent sampling settings (Top-K, Top-P, repetition penalties) and reasoning 'thinking box' inspection

**Limitations:** Janitor+ Router is restricted to paid $12.99/mo subscribers on the web and still bills extra per token used; Free-tier JLLM users can experience slower response speeds or generation inconsistencies during peak traffic; Steep learning curve for casual users navigating proxy endpoints, token limits, and advanced sampling sliders

## 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
