Free AI mini-apps

Tools

Useful mini-apps, available directly in your browser.

Which tool should you use, and when?

These mini-apps support GEO scoping, LLM cost estimation, local infrastructure planning and schema markup. They provide a usable starting point before an audit or AI integration project.

Free AI Answer Generator

Enter your question, choose a tone and language, and get an answer in seconds. 100% free, no sign-up.

When to use it
Use it when you want to turn a service page or article into a short, structured answer that AI search engines can cite more easily.
Limitation
The tool does not replace real business proof: always add metrics, sources and examples from your own projects.
Example
Example: generate an 80-word block explaining a GDPR-compliant RAG chatbot for a service page.

RAG & LLM Cost Calculator

Estimate your LLM architecture budget in seconds. Calculate input tokens, output tokens, and vector indexing costs for GPT, Claude and Mistral.

When to use it
Use it when you are planning a RAG chatbot, internal assistant or LLM automation and need to estimate monthly budget before technical scoping.
Limitation
The calculation is an estimate: real costs depend on caching, model routing, embeddings and document volume.
Example
Example: compare GPT-5 mini and Mistral for 2,000 support conversations per month.

VRAM & Hardware Simulator for On-Premise LLMs

Enter the model size, quantization, and context window to estimate the required GPU memory and compatible hardware configurations.

When to use it
Use it when you are checking whether an open-source model can run on your GPU, dedicated server or on-premise infrastructure.
Limitation
VRAM alone is not production sizing: keep margin for context length, batching, latency and traffic spikes.
Example
Example: check whether a quantized 7B model can process internal tickets without a US API.

Structured Outputs Schema Generator

Describe in plain language the data you want to extract, and instantly get a production-ready Pydantic class or JSON Schema for OpenAI Function Calling or Instructor.

When to use it
Use it when you need clean JSON-LD for a service, article, tool, FAQ or case-study page before validation.
Limitation
Generated schema must be reviewed: only mark up information that is actually visible on the page.
Example
Example: generate Service + FAQPage markup for a GDPR-compliant AI integration page.
