## 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

## TrainEngine.ai

TrainEngine.ai is built for creators who want their own image model rather than a prompt library. You bring a set of reference images — a character, a product line, a drawing style, an illustration style for children's books — and the platform fine-tunes a Stable Diffusion model on them using DreamBooth, running the compute in the cloud so a local GPU is not required. Stable Diffusion XL is supported for fine-tuning alongside SD 1.5.

The result is a model you can then generate from endlessly. The site surfaces a public community gallery, where trending models and their generation counts show what other users are producing, from anime characters and comic styles to character sheets and game assets. If you would rather keep your work to yourself, the private option hides both the model and every image generated inside it.

Pricing is pay-as-you-go with non-expiring tokens: training a public model costs 10 tokens, a private model 25, a revision 10, and image generation 1 token per image, with packs from $10 for 100 tokens up to $70 for 1,400. Trained SD 1.5 models download as .CKPT and SDXL models as LoRA files, both compatible with common local UIs. Larger teams can contact TrainEngine for enterprise API access to call their models from their own software.

**Pricing & Plans:** TrainEngine.ai is paid and usage-based rather than subscription-based. New accounts get 10 free tokens. Token packs cost $10 for 100, $20 for 250, $30 for 450, $50 for 850 and $70 for 1,400 tokens, with the per-token rate dropping as packs get larger. Training a public model costs 10 tokens, a private model 25 tokens, a model revision 10 tokens, and image generation 1 token per image. Tokens never expire and there is a separate enterprise API tier on request.

- **DreamBooth model training:** Upload your own images and fine-tune Stable Diffusion models in the cloud using DreamBooth, including Stable Diffusion XL, without needing a local GPU.
- **Public and private models:** Choose public models that the community can discover and generate from, or private models whose images stay exclusive to your account.
- **Unlimited image generation:** Every trained model becomes a generator that can produce unlimited AI assets in its learned style and subject matter.
- **Model revisions and downloads:** Refine existing models with revisions and download finished weights in .CKPT (SD 1.5) or LoRA (SDXL) format for use in other tools.
- **API integration for teams:** Enterprise API access lets you plug trained models into apps, websites and internal company workflows.

**Strengths:** No local GPU or technical setup required — training runs in the cloud; Fine-tuning covers both Stable Diffusion 1.5 and Stable Diffusion XL; Private models keep both the weights and generated images visible only to you; Non-expiring pay-as-you-go tokens suit occasional trainers better than a monthly subscription

**Limitations:** Token-based pricing means costs scale with model revisions and image generations, which can add up for heavy experimentation; Training runs in the cloud are asynchronous, so there is waiting time before a model is ready to generate; Free tier is limited to public models and public image generations; private work requires paid tokens; Model quality depends heavily on the quality and captioning of the source images you upload
