Its core is a set of free, browser-based utilities: an LLM cost calculator that estimates API spend across providers, a prompt tokenizer for counting tokens and trimming prompt length, a model selector quiz, a benchmark comparator using metrics like MMLU and HumanEval, a local LLM runner guide for Ollama and LM Studio, an open-source model directory and a glossary of AI terms. Beyond the calculators, ModelFusion also markets a product layer: MultiChat for comparing responses from multiple models side by side, document projects for chatting with uploaded PDFs and Word files, a unified API that presents one interface across providers, and usage analytics for tracking cost and performance. The site positions these as suitable for research, business, development and education audiences. Much of the toolkit is completely free and needs no registration, with the latest model pricing and benchmark data refreshed regularly. Because the underlying costs it reports come from third-party providers, users should still confirm current rates with OpenAI, Anthropic, Google or whichever vendor they rely on, as provider pricing changes often. **Pricing & Plans:** ModelFusion's calculators, prompt library and comparison tools are advertised as 100% free with no registration required. The platform also lists paid tiers (a Free Trial and Paid options) for its API and enterprise-style usage, so teams needing the unified API or dedicated support should check current plans on the site. - **LLM cost calculator:** Estimate API costs for GPT-4, Claude, Gemini and 25+ models and compare pricing across providers before you spend. - **Prompt library and tokenizer:** Access a large library of ready-made prompts and count tokens for any model to reduce cost and improve efficiency. - **Model selector and benchmark comparator:** Find the best model for a use case and compare MMLU, HumanEval and other performance metrics interactively. - **MultiChat and document projects:** Chat with several AI models at once for side-by-side comparison, and upload PDFs or Word files to query them with AI. - **Unified API and observability:** Use a single consistent interface across providers, with analytics for tracking usage, cost and performance. **Strengths:** Large collection of genuinely free utilities with no sign-up needed.; Useful for comparing pricing and benchmarks across many models in one place.; Covers practical extras like token counting and local model setup guides.; Includes a MultiChat view for comparing model answers directly. **Limitations:** Some tools are informational and model data can lag behind very fast-moving provider updates.; Cost figures are estimates based on third-party pricing and should be verified with each provider.

The concept is straightforward: give an agent a well-designed workflow, and it can produce a complete, presentable artifact rather than a rough draft. Skillry focuses on deliverables you would actually show, spanning web pages and landing pages, slide decks, images such as OG graphics, and short videos. The key differentiator is that Skillry designs the output first. Its team art-directs a finished piece — a page, a deck, a film — then writes the original instructions, templates and scripts that let your agent reproduce that style. Each Skill page displays a real result it made, so you can see the visual point of view before installing. Skills are maintained by the same team as agents and models evolve. Installation is agent-first. You can browse the catalog on the web, connect via MCP so your agent can search and inspect Skills, or install from the CLI. Free Skills require only a sign-in, while Premium Skills come with a Pro subscription or a one-time lifetime purchase. Model, API and rendering costs are handled by your own environment, not by Skillry. **Pricing & Plans:** Free Skills are available with a sign-in. Pro is $9.99/month (regularly $19.90) or $79/year (regularly $158), and a Founding Lifetime plan costs $169 one-time. All paid plans include Premium Skills, MCP/CLI/web install and ongoing updates; model and rendering costs are extra. - **Original in-house Skills:** Every Skill is designed, written and tested by the Skillry team, with templates and scripts built from a finished piece of work. - **Multiple output types:** Skills cover web pages, slide decks, images, video and reports, so your agent can produce a range of assets. - **Broad agent support:** Install and run Skills inside Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI and more. - **Preview before install:** Each Skill page shows a real result it generated, so you can judge the visual style before adding it. - **Flexible installation:** Add Skills from the web, through an MCP connection or from your CLI, with browser-based authorization. **Strengths:** Original Skills designed and maintained in-house; Covers websites, slides, images and video in one library; Works across Claude Code, Codex, Cursor and many other agents; Each Skill previews a real result before you install **Limitations:** Full access to Premium Skills requires a paid plan; Model, API and rendering costs are separate from the subscription; The catalog is newest to market, so coverage keeps evolving [Profile (Markdown)](https://openaitools.app/tool/skillry.md) ## Frequently Asked Questions ### How do ModelFusion and Skillry compare in monthly traffic?
