Wikipedia is a great resource for getting a quick overview of a topic. But sometimes the articles are too long or too technical. Simple Wikipedia helps, although it can still be pretty lengthy and not always simple enough. Or it might be too simple, depending on what I am trying to learn. I’ve always wanted to be able to choose the level of detail and length based on what I am looking. Sometimes when I am researching a new topic and come across 10 new terms, all linking to their own detailed Wikipedia pages, I just want to get a 50-100 word gist. Other times, I want to get a 1000-word summary of a topic I am sort of familiar with but don’t know well enough.
I have this same need for other text-based content like news articles and technical documents. And I believe a solution for this would improve readability and thus improve comprehension for everyone.
Readability refers to the ease with which a reader can read and understand a written text. It is influenced by factors such as sentence length, word complexity, and the structure of the text.
Comprehension is the reader’s ability to absorb and interpret the information presented in the text. The best way to explain any concept or information is to cater to the reader’s level of understanding and prior knowledge. This can be achieved by using familiar language, breaking down complex ideas into smaller parts, and using examples or analogies that the reader can relate to.
If you can easily understand what you’re reading, it’s good!

When things are written in a way that’s easy to understand, it’s better for the reader.
8th grade
Content that is written in a clear and simple way is easier for people to understand.
10th grade
If the material you’re reading is written in a clear and straightforward manner, it becomes easier to comprehend and interpret.
12th grade
When content is written in a way that is easily understood, it facilitates comprehension and enhances the reader’s ability to absorb the information.

Modern browsers like Safari and Chrome, e-book readers like Kindle, and word processors like MS Word and Google Docs make it easy to read text on a screen by letting the user set the zoom-level or font-size. Some even simplify the view by removing ads, sidebars, and other distractions, as well as using high contrast colors for the text and background. I think someday in the future, along with adjusting zoom-level, font-size, and colors, we will have a couple of more sliders in every reader: level and length.
Level is reading comprehension level, from 1st grade to 12th grade, from college first year to 20-year expert in field. Level can also automatically use sensible euphemisms for younger readers to reduce the details of gore, violence, or explicit verbiage.
Length is for specifying the number of words, from summary (50-100 words) to detailed (1000-1500 words). Length is about focusing on the core concepts of the text to best explain the material, and not just listing the “Top 5 Things About…”
This is the current Mobile Safari Reader options panel:
This is what I hope to see someday, not just in Safari but in every browser:
A similar user interface could also be shown when selecting any text. In addition to copy, share, web search, and define menu options, users could be offered an “Explain” option that would let them choose the level and length of the explanation.
At present, OpenAI GPT-4 is the only AI large language model (LLM) capable of doing an acceptable job at taking a few pages worth of text and rewriting it to a different reading comprehension level at a different length. I tried a few different cloud LLMs, but their results were not good enough. Either way, cloud LLMs are not an acceptable path forward because they can get expensive for longer source texts, do not work without Internet connection, and there are privacy and copyright concerns with sending full text to third parties.
My hope is that local LLMs will continue to improve and in a few years (maybe 5-10), almost all consumer-level devices will have their own version of GPT 4+, capable of re-explaining or rewriting any source content, without the need for an Internet connection. It is already possible as a proof-of-concept using graphics cards on newer laptops and phones. Give it a few more years of innovation, and we’ll wonder how we lived without it, like search engines and smartphones.
While major browsers might take a few years to bundle this feature, popular news sites might start offering “Readability” options for their articles. It would be akin to offering the same article in multiple languages.
There should always be an option to view original source text and any rewritten text should be clearly highlighted. Thankfully, we already have those types of identifying markers and warnings when translating between languages today. LLMs can be used to perform translations within the same language to address varying comprehension levels at multiple word lengths and the same type of warnings should be shown.
I think so. And that is why I spent $50+ on GPT-4 API to rewrite these Wikipedia articles at 4 different levels and 3 different lengths each. Converting all 6.6 million articles on English Wikipedia would cost about $10-15 million at this rate, not cheap but also not impossible.
Dear OpenAI and Anthropic, please make wiki.openai.com or wiki.anthropic.com happen! Make it work like the demo here: Readability Demo
After I experimented with rewriting text content in a lot of different ways with number of local and cloud LLM APIs for weeks, I settled on using specific grade level and length system prompts for OpenAI GPT-4 API. I ended up with 4 reading levels and 3 different word lengths. In addition to being expensive, GPT output was not substantially different for every grade level and due to the non-deterministic nature of output, sometimes grade 4-5 would be more complex than grade 6-7, or text limited to 50-100 words would be longer than text for 150-200 words. Here are the final parameters:
I tried out various combinations of the above parameters with a few different Wikipedia articles until the results matched my expectations and then finalized a variety of articles. I wrote a script that downloads the plain-text version of each article once, and then calls OpenAI GPT-4 API for every combination of selected level and length (total 12 times) per article. Shorter lengths cost less, longer ones more.
When I said I tried out various combinations above, I meant I played around with detailed, custom prompts for each combination. Prompt just means what you want the GPT to do and how you want it to respond. I started with a generic “Rewrite the following text in 50-100 words (1-3 sentences) such that a 2nd Grade Student (age 7) can understand it.” It sounds like it should work, but unfortunately it did not for most articles.
Often the language in the response came out more complex or the length was unpredictable. LLMs just aren’t good enough to read between the lines yet. You have to specify a lot more in a prompt - what should the tone of the output be? Funny or dry? How detailed should the factual information be? Should the response be broken up into various sections? And most importantly, who is the writer that GPT is pretending to be? A helpful school teacher, a prolific journalist, or an esteemed researcher? Each of them would write differently for each target audience. After a few weeks of fiddling around, this is what I came up with for each length.

After my script downloaded 12 versions of each Wikipedia article and saved them to my local machine, one final script took all the outputs from all the articles and merged them into one large file that is used in the demo.
This way if I want to add or replace articles, I can just regenerate the full demo automatically.
