AI & LLM tools

Estimate LLM API bills and prompt-caching savings, size GPU memory for local models, convert JSON to TOON, and publish llms.txt and AI-crawler robots.txt rules.

• AI agent cost calculatorEstimate growing conversation costs with a per-turn ledger, retries and reasoning assumptions.
• AI crawler robots.txt generatorChoose AI crawl preferences, merge robots.txt, and test paths with RFC matching rules.
• Context window calculatorCheck instructions, schemas, documents, history and output reserves against model limits.
• JSON to TOON converterConvert JSON and TOON locally, verify a round trip, and compare text sizes.
• LLM API cost calculatorEstimate token costs per request, day and month with editable prices and model comparisons.
• LLM VRAM calculatorEstimate local LLM weight and KV-cache memory, GPU fit, and maximum context.
• llms.txt generatorBuild a Markdown guide to your site, validate its structure, and download llms.txt.
• Long-context pricing calculatorCompare costs around a prompt threshold and budget a distribution of request sizes.
• Prompt caching savings calculatorCompare cache writes and reads with ordinary input billing, and find the reuse break-even point.
