## RunningHub

RunningHub is an all-in-one AI content creation platform built around cloud ComfyUI. Instead of installing Stable Diffusion, Flux, ControlNet, and LoRA setup on your own GPU, you run workflows on RunningHub's servers and interact through a browser. The platform supports importing and running ComfyUI graphs, then turning them into polished single-click "AI Apps" that non-technical users can operate with simple prompts.

Beyond the workflow engine, RunningHub bundles a broad creative toolkit: text-to-image and text-to-video generation, image-to-image and image-to-video conversion, inpainting, outpainting, and upscaling powered by self-developed models. An infinite canvas and rapid-creation templates help users assemble campaigns, product visuals, and short videos. The homepage also showcases a community gallery of featured workflows, model APIs, and viral video templates.

RunningHub follows a freemium, credit-based model with free daily usage and subscription tiers for heavier production. It targets creators, small studios, and developers, and offers workflow, model, LLM, and app APIs so teams can embed generational capabilities into their own products.

**Pricing & Plans:** Freemium with daily free credits and pay-as-you-go credits; subscription tiers unlock higher concurrency, member discounts, and advanced models. API usage is priced separately.

- **Cloud ComfyUI:** Run, import, and share ComfyUI workflows in the cloud without local GPU hardware.
- **AI Apps Builder:** Publish a workflow as a single-click AI app that anyone can run with simple inputs.
- **Image & Video Generation:** Use hosted image and video models, including self-developed upscaling and enhancement tools, from one dashboard.
- **Developer APIs:** Integrate generation into your product via workflow, model, LLM, and app APIs.
- **Template Library & Community:** Explore a gallery of community workflows, viral video templates, and creator rewards.

**Limitations:** Complex workflows have a learning curve; Credit-based costs add up for heavy video generation; Best experience assumes some ComfyUI familiarity

## Scribble Diffusion AI

Scribble Diffusion AI targets the gap between a napkin sketch and a presentable image. Instead of describing a picture entirely in words, you supply the composition itself — drawn in the browser or uploaded from paper — and add a prompt to control style, colour and material. The result is a refined image that preserves the structure of your sketch while filling in the rendering detail that is hard to draw by hand.

The workflow is a short loop: draw or upload, type a prompt, generate, then adjust the prompt and generate again. Because the sketch stays fixed between runs, it is easy to explore variations on one idea rather than starting over each time. A public Explore section collects outputs from other users, which is useful both for inspiration and for judging whether the model's style matches what you want before spending credits.

It is a browser-based paid service built around a credit system. A free plan provides a handful of credits, a one-off Starter pack suits occasional use, and Premium and Advanced subscriptions supply larger monthly allowances. The site states that payments run through Stripe and that refunds are not available, so it is worth testing with the free credits first. Note that this is an independent tool rather than an official release from any particular AI research lab.

**Pricing & Plans:** Freemium with paid credit packs and subscriptions. A free plan includes a small number of credits. The Starter plan is a one-off purchase of 100 credits. The Premium plan is a monthly subscription (300 credits) and the Advanced plan is an annual subscription (5,000 credits), both bundling high-quality output and faster generation. Seasonal discounts have appeared on the site, so check the pricing page for current figures.

- **Sketch or upload, then generate:** Use the built-in canvas to draw your idea, or upload an existing sketch, then submit it with a text prompt. The service renders a refined image that follows both the shapes you drew and the description you typed.
- **Prompt-driven variation:** Iterate by changing the prompt while keeping the same drawing, so a single sketch can branch into several visual directions — different colours, styles, materials or lighting on the same composition.
- **High-quality output and faster generation:** Images are returned in a high-quality format and paid plans prioritise generation speed, so you are not waiting on long queues when you are working through a set of ideas.
- **Explore gallery for reference:** A public Explore gallery shows what other users have produced, which is a quick way to understand the range of styles the model handles before you commit to a credit purchase.
- **Multi-language interface:** The interface and copy are available in several languages — including Simplified Chinese, Japanese, Spanish, German and French — making the workflow accessible to non-English speakers.

**Strengths:** Keeps the composition of your own sketch rather than inventing a scene from text alone; Free credits let you evaluate output quality before paying; One-off credit pack available for people who do not want a subscription; Prompt re-runs on the same sketch make iterating on a single idea quick

**Limitations:** Credit packs are consumed per image, so heavy experimentation adds up quickly; No refunds are offered once credits are spent on image processing; Results depend heavily on prompt quality, so a rough sketch alone will not guarantee a good render; Server-side generation means queue times can vary when the service is busy
