Type what you want in plain English. The AI Transform engine decomposes it into a 6-band structured prompt that any LLM can execute with maximum fidelity. Powered by a fine-tuned 7B model running in your browser.
The sinc-LLM AI prompt generator uses a fine-tuned 7-billion parameter language model trained specifically on the task of prompt decomposition. Unlike generic prompt generators that use templates or simple reformatting, sinc-LLM performs genuine signal analysis on your raw input.
The underlying theory is the Nyquist-Shannon sampling theorem applied to natural language specification:
Your raw prompt is the continuous signal. The AI Transform model samples it at 6 critical frequencies — PERSONA, CONTEXT, DATA, CONSTRAINTS, FORMAT, and TASK — producing a discrete representation that captures the full bandwidth of your intent. When the LLM reads these 6 bands, it reconstructs your specification without aliasing.
Enter any prompt in natural language. One sentence or ten paragraphs — the AI handles any length.
The fine-tuned model analyzes your input and extracts content for all 6 frequency bands automatically.
Receive a complete sinc JSON prompt ready to paste into ChatGPT, Claude, Gemini, or any LLM.
Most AI prompt generators use static templates: "Act as a [role], I want you to [task], output as [format]." These templates cover 2-3 specification dimensions at most, leaving the LLM to guess the rest.
The sinc-LLM approach is fundamentally different. Instead of filling templates, the AI analyzes what specification dimensions are present in your raw text, what dimensions are missing, and what content should fill those gaps based on the context of your request.
For example, if you write "help me write a cover letter for a data science job," the AI prompt generator recognizes:
The generator fills in reasonable defaults for missing bands while flagging them so you can customize. This means every generated prompt is complete — no specification gaps for the LLM to fill with guesses.

Notice how the AI generator added critical specification that was completely absent from the raw input: rate limiting, error handling, legal considerations, output format, and library choices. Without these bands, the LLM would make arbitrary decisions about each dimension.
Rapid prototyping: When you know what you want but do not have time to write a detailed prompt, paste your rough idea and let the sinc-LLM AI prompt generator structure it for you.
Prompt library building: Generate structured prompts for common tasks, save them as .sinc.json files, and reuse them across projects. The JSON format is version-controllable and diffable.
Teaching prompt engineering: Show students how a raw prompt maps to the 6-band structure. The generated output makes the implicit explicit, which is the core skill of prompt engineering.
Multi-model testing: Generate one structured prompt, then test it across ChatGPT, Claude, Gemini, and Grok. The 6-band format is model-agnostic, so you get a fair comparison of model capabilities rather than model sensitivity to prompt phrasing.
Agent system development: The sinc JSON format serves as the inter-agent communication contract in multi-agent architectures. Generate the initial prompt structure, then let agents pass sinc JSON to each other with full specification fidelity.
The number 6 is not arbitrary. Research into LLM specification failures revealed that prompts fail along exactly 6 orthogonal dimensions: identity (who), background (what surrounds the task), input (what to work with), rules (what to avoid), structure (how to output), and action (what to do). These map to PERSONA, CONTEXT, DATA, CONSTRAINTS, FORMAT, and TASK respectively.
The sinc-LLM prompt generator treats these 6 dimensions as the Nyquist frequency of prompt specification. Sample at this rate and you capture the full bandwidth of human intent. Sample below it (fewer than 6 bands) and you get aliasing — the LLM fills gaps with assumptions that may not match your intent.
This is why the CONSTRAINTS band (n=3) is always the longest. Constraints carry the most specification density — they are the high-frequency components of your intent. A prompt without explicit constraints is like an audio signal sampled at too low a rate: it sounds wrong, and you cannot fix it by amplifying the signal.
