Calculate the actual cost, capacity, ROI.
Twelve calculators every AI builder reaches for. Inline math, real model prices, honest assumptions. Each calculator has worked examples you can load with one click.
Cost calculator
What an AI workload actually costs per month. Input tokens, output tokens, request volume, model choice — the math for real budgets.
Token counter
How many tokens is your prompt? Estimate input + output for the major models. Plan context budgets.
Model comparator
Side-by-side cost + capability for Claude vs GPT vs Gemini vs open-weight options. Honest tradeoffs.
Stack recommender
Given your use case + budget + latency requirement, what model + framework + hosting stack makes sense.
Hardware calculator
Self-hosting an open-weight model. GPU memory math. Quantization tradeoffs. What you actually need.
Break-even calculator
When does self-hosting beat API spending? The crossover analysis with honest assumptions.
Prompt diff
Compare two prompts. Measure the change. Estimate the impact on cost and behavior.
ROI calculator
What's the actual business case for AI in your workflow? Time saved, error rate, opportunity cost — the inputs to a real ROI number.
Redact estimator
How much of your data needs to be redacted before going to a third-party API? PII rate × volume × cost.
Jailbreak checker
Estimate how vulnerable your system prompt is to known jailbreak categories. Diagnostic, not exhaustive.
Context fit
Will your RAG corpus + prompt + tool definitions fit in the model's context window with room for the answer?
Carbon calculator
Estimate the energy + CO₂ of your AI workload. Inference-only; training emissions are separate.
