What Samprix is for

AI tools are now part of everyday work, but the small jobs around them are fiddly: cleaning up text you copied from a chatbot, checking whether a long document fits in a context window, or working out which subscription or API is worth paying for. Samprix builds simple, fast tools for those jobs.

The tools

Every tool is free and works without an account:

• AI Text Cleaner: Paste text from ChatGPT, Claude or Gemini and get clean plain text back.
• Word, Character & Token Counter: Count words, characters and tokens, and see how much of each chatbot’s limit you use.
• Context Window Checker: Paste text or drop a PDF and see which ChatGPT, Claude, Gemini and local models can take all of it.
• AI Subscription Comparison: ChatGPT, Claude and Gemini paid plans side by side: price, limits and features.
• AI API Cost Calculator: Estimate monthly API cost across models, including caching and batch discounts.
• AI API Pricing by Model: Every model’s API prices, and any two models compared head to head.
• AI Subscription vs API Calculator: See how many messages a day it takes before a ChatGPT, Claude or Gemini plan beats paying per token.

• Which AI Should I Use?: Answer four questions and see which ChatGPT, Claude or Gemini plan fits, with reasons.

How we work

• Your text stays on your device. Our text tools run in your browser. What you paste isn’t uploaded to us.
• Every number has a source. Prices, plan limits and specs come from the provider’s own pages. We link to the source and show the date we last checked it. Read our methodology.
• Estimates are labeled as estimates. When we can’t measure something exactly, for example Claude’s or Gemini’s token counts, we say so.
• We’re independent. Samprix isn’t affiliated with OpenAI, Anthropic, Google or any other AI company.

How the numbers stay current

AI prices and plans change often, so a figure is only as good as the day it was read. API prices are re-read every day, automatically, from OpenAI’s, Anthropic’s and Google’s own pricing pages. Where a provider’s page blocks automated checks, we check it by hand every month. A figure’s “last checked” date only moves forward when the provider’s page confirms it, and if a provider doesn’t publish a number, we leave it out rather than estimate it. The methodology page lists every source and how each tool does its math.

How Samprix is funded

The tools are free. We show ads, served by Google AdSense, below the tools and in guide content, never above the box you type into. Some future pages about running AI on your own computer may include affiliate links to hardware. Those links will always be clearly marked, and they never affect what we recommend.
