What Are AI & Creator Tools?
AI tools are utilities designed to help you work more effectively with large language models like OpenAI’s GPT, Anthropic’s Claude, and Google’s Gemini. The creator and marketing tools help YouTubers, podcasters, newsletter writers, influencers, and paid media teams estimate earnings, plan ad budgets, and set rates. Every tool runs entirely in your browser โ no API calls, no sign-ups, nothing uploaded or stored.
AI Cost & Token Tools
The AI Token Counter tells you exactly how many tokens your text contains โ running the real tokenizer for OpenAI models, with close estimates for Claude and Gemini. The LLM API Cost Calculator converts token counts into a dollar figure across all major providers, sorted cheapest first. The Embedding Cost Calculator prices OpenAI and other embedding API calls for RAG pipelines and semantic search. The AI Image Generation Cost Calculator estimates per-image and monthly costs across Midjourney, DALLยทE, and Stable Diffusion. The AI Response Length Estimator lets you budget token output before running prompts.

Paid Ads & Marketing Tools
The Meta Ads Break-Even Calculator finds the exact ROAS your Meta campaigns need to be profitable based on your gross margin โ not a generic 4x benchmark. The Facebook Ads Budget Calculator works backwards from your target results to tell you how much to spend. The Ad Frequency & Reach Calculator models how frequency, reach, and impressions interact across your audience. Together these three tools cover the core economics of running paid social campaigns profitably.
YouTube Creator Tools
The YouTube Money Calculator estimates ad revenue from monthly views and RPM by niche. The YouTube RPM Calculator works backward from your actual earnings to reveal your true revenue per mille. The YouTube Shorts Revenue Calculator models Shorts-specific monetisation and compares it against long-form. The YouTube Watch Time Calculator totals your hours across a video library and shows progress toward the 4,000-hour monetisation threshold. The YouTube Tag Generator builds optimised tag sets from your video topic to improve search discoverability.
Sponsorship & Creator Revenue
The Podcast Sponsorship Calculator estimates pre-roll and mid-roll rates from your download count and niche CPM. The Newsletter Sponsorship Calculator prices sponsorships on opens rather than raw subscriber count โ the industry standard. The Influencer Rate Calculator estimates a fair sponsored-post rate from follower count, engagement rate, and platform, with a negotiating range. The Affiliate Earnings Calculator models monthly and annual affiliate income for flat, percentage, and recurring SaaS commission structures.
AI Model & Prompt Tools
The AI Model Comparison puts every major model side by side โ pricing, context windows, vision, reasoning, and tool use. The AI Prompt Generator assembles structured prompts from templates for ChatGPT, Claude, Gemini, and any other chatbot. The Tokens to Words Converter converts instantly between tokens, words, and characters for quick estimates.
