 # Cellm
-Cellm is an Excel extension that lets you use Large Language Models (LLMs) like ChatGPT in cell formulas.
+Use AI in Excel formulas to run your prompt on thousands of rows of tasks in minutes.
 
 ## What is Cellm?
-Cellm's `=PROMPT()` function outputs AI responses to a range of text, similar to how Excel's `=SUM()` function outputs the sum of a range of numbers.  
+Cellm is an Excel extension that lets you use Large Language Models (LLMs) like ChatGPT in cell formulas. Cellm's `=PROMPT()` function outputs AI responses to a range of text, similar to how Excel's `=SUM()` function outputs the sum of a range of numbers.  
 
 For example, you can write `=PROMPT(A1, "Extract all person names mentioned in the text.")` in a cell's formula and drag the cell to apply the prompt to many rows. Cellm is useful when you want to use AI for repetitive tasks that would normally require copy-pasting data in and out of a chat window many times.
 
-## Key features
-This extension does one thing and one thing well:

+## Why use Cellm?
+- Make quick work of data cleaning, classification, and extraction tasks that once took hours.
+- Immediately free your team from repetitive manual work with the spreadsheet they already master.
+- Bypass lengthy rollouts of many AI systems. Your team already have Excel on their computers.
+- Enable marketing, finance, sales, operations and other teams to automate everyday tasks without depending on developers.
 
-- Calls LLMs in formulas and returns short answers suitable for cells
-- Supports models from Anthropic, Mistral, OpenAI, and Google as well as locally hosted models via Llamafiles, Ollama, or vLLM
+> “I love feeding data to ChatGPT, one copy-paste at a time”
+> — no one who’s run the same prompt 5 times

 ## Basic usage
 
 Select a cell and type `=PROMPT("What model are you and who made you?")`. For Gemma 2 2B, it will tell you that it's called "Gemma" and made by Google DeepMind.
 
 You can also use cell references. For example, copy a news article into cell A1 and type in cell B1: `=PROMPT(A1, "Extract all person names mentioned in the text")`. You can reference many cells using standard Excel notation, e.g. `=PROMPT(A1:F10, "Extract all person names in the cells")`

 ## Why did we make Cellm?
 A friend was writing a systematic review paper and had to compare 7,500 papers against inclusion/exclusion criteria. We thought this was a great use case for LLMs but quickly realized that individually copying papers in and out of chat windows was a total pain. This sparked the idea to make an AI tool to automate repetitive tasks for people who would rather avoid programming.
