Show HN: Summarize Selection with ChatGPT Bookmarklet
Here is a video of how it looks: https://www.youtube.com/watch?v=PPSMgJa8YHQ (this video is from my extension which uses the same code, but I forgot I can make it into a bookmarklet: https://github.com/jackdoe/ffs-ungpt)
You can see the expanded code at https://gist.github.com/jackdoe/ce5a60b97e6d8487553cb00aa43fe0c6#file-chatgpt-summarize-bookmarklet
Bookmarklet code:
javascript:(function(api_key) { var selection = window.getSelection().toString(); if (selection.length == 0) return; var xhr = new XMLHttpRequest(); xhr.open("POST", "https://api.openai.com/v1/chat/completions"); xhr.setRequestHeader('Content-Type', 'application/json'); xhr.setRequestHeader('Authorization', 'Bearer ' + api_key); window.scrollTo({top: 0}); window.document.body.innerHTML = 'asking...'; window.document.body.style.backgroundColor = "white"; window.document.body.style.color = "black"; window.document.body.style.fontFamily = 'monospace'; window.document.body.style.fontSize = "16px"; window.document.body.style.margin = "auto"; window.document.body.style.padding = "1rem"; window.document.body.style.maxWidth = "60rem"; xhr.onreadystatechange = function() { if (xhr.readyState == 4) { if (xhr.status == 200) { var response = JSON.parse(xhr.responseText); var summary = response.choices[0].message.content; window.document.body.innerHTML = summary } else { try { var e = JSON.parse(xhr.responseText); window.document.body.innerHTML = e.error.message } catch(e) { window.document.body.innerHTML = 'error asking.. check the console'; console.log(xhr) } } } }; var data = JSON.stringify({ "model": "gpt-3.5-turbo", "messages": [ {"role": "system", "content": "Summarize the following text as if you are Richard Feynman"}, {"role": "user", "content": selection} ] }); xhr.send(data);})("YOUR API KEY HERE")
Just select a bunch of text and click the bookmarklet, it will replace the page with the chatgpt answer of "Summarize the following text as if you are Richard Feynman"
