Cost & pricing

LLM Cost Calculator Price a single LLM API call or a whole batch: pick a model, set input and output tokens, get the cost. Meeting Cost Calculator Put a dollar figure on any meeting from attendees, average pay and duration — with a live ticking burn meter. AI Chatbot Cost Calculator Work out a chatbot's monthly and yearly API bill from daily messages, tokens per message and the model. AI GPU Cost Calculator Estimate cloud GPU cost from wall-clock hours, GPU count and the price per GPU-hour. ChatGPT Plus vs API Calculator Compare a flat ChatGPT Plus subscription against metered API cost and find your break-even point. Embedding Cost Calculator Price an embedding job and its vector storage from the number of texts, tokens each and the model. Fine-Tuning Cost Calculator Estimate LLM fine-tuning cost from training tokens, epochs and the per-million training rate. AI Rate Limit Calculator Turn RPM and TPM limits plus request size into a live headroom gauge and your real max throughput. AI ROI Calculator Weigh AI cost against hours saved to get a live ROI percentage and payback months. AI Spending Forecast Project monthly AI spend forward from your current bill and a growth rate, with a live chart. AI Agent Conversation Cost Calculator Estimate a multi-turn AI agent conversation's cost, showing how resent history makes tokens climb quadratically. AI Coding Cost Calculator Compare Cursor, Copilot, Claude Code and raw API costs for your actual coding volume, including metered overage. AI Cost Per User Calculator Work out the monthly AI cost of one user and the margin against what you charge, so you know your unit economics. AI Subscription Cost Calculator Add up ChatGPT Plus, Claude Pro, Cursor and every other AI plan you pay for to see your real monthly and annual AI spend. AI vs Human Writing Cost Calculator Compare the monthly cost of AI-plus-editing against a human writer, with editing overhead made explicit. Model Switch Savings Calculator Compare two AI models on your own traffic to see the monthly and yearly cost of switching from one to the other. Prompt Caching + Batch Savings Calculator Work out how much prompt caching plus the batch API discount cut the cost of a repeated LLM workload. Reasoning Token Cost Calculator Estimate the hidden reasoning (thinking) tokens a model like o3 burns and what they add to your real per-call cost. Self-Hosted vs API Break-Even Calculator Compare your API bill against renting GPUs and see the monthly token volume where self-hosting an LLM starts to pay off. AI Voice Agent Cost-Per-Minute Calculator Add up speech-to-text, the LLM and text-to-speech to see what an AI voice agent costs per minute, per call and per month.

Tokens & context

AI Token Counter Paste text and see an estimated token count, characters, words and input cost per model, live as you type. Prompt Token Estimator Estimate a prompt's token size and cost before you call the API — live as you type, per model. Context Window Planner See system, docs, history and reply fill a model's context window on a live bar — with an overflow warning. Image Token Calculator Count image input tokens and cost for GPT-4o vision from dimensions or a preset, high or low detail. Dataset Size Calculator Turn rows × average length into an estimated token count, storage size and embedding cost. Document Token & Cost Estimator Estimate how many tokens a document holds and what it costs to send, from pasted text or a word/page count. LLM Speed Calculator Turn a model's tokens-per-second rate and time-to-first-token into the real wall-clock time to generate a response. Quantization Size Calculator (GGUF) Estimate the GGUF file size, VRAM and KV-cache of a quantized local LLM from its parameters and quant level.

Compare & learn

AI Model Comparison Sort and filter LLMs by input price, output price and context window in one live table. AI Glossary Search plain-English definitions of AI and LLM terms — tokens, RAG, context windows and more. AI Readability Checker Score AI output or any text for Flesch reading ease and grade level, and flag dense writing. AI Writing Heuristic Checker Count the surface patterns common in AI writing — em-dashes, stock vocabulary, low sentence variance — with every number shown and nothing hidden.

Footprint & impact

AI Carbon & Water Footprint Calculator Estimate the yearly energy, carbon and water footprint of your AI prompts, with relatable comparisons.

Built to show where the cost comes from.

A single price-per-token number is hard to reason about. These tools break it down by input, output and cached tokens, across the models you actually use, so you can size a feature, compare providers and forecast the monthly bill before you ship.
