• (2025-08-13) Виктор Виктор: only 1 free use per day
• (2025-08-12) Andre: Very useful tool - transcript, load into AI for a summary or analysis. Excellent tool I use most everyday.
• (2025-08-11) Mike MacDonald: Very useful tool - hits all of our main reqs
• (2025-08-09) Ran: For the past few months as a paid user already, I have experienced transcription speeds which are far slower than that of competing plugins (some of which are even free). Of course I am referring to videos which were not already transcribed by others and therefore only retrieved from storage. Also, transcription fails for many videos with the error message of "Unfortunately, subtitles are unavailable for 12% of the videos..." despite subtitles being available for the video in question and other plugins being able to extract and summarize them. I get the impression that Eightify developers are not keeping up with the latest working methods to retrieve subtitles from YouTube videos leading to many failures with false error messages and they are not paying for sufficient AI transcription speeds or not expanding previous capacity to keep up with a growing user base.
• (2025-08-08) Ron Javier: Eightify's been super useful at transcribing videos in a pinch which I use for my AI workflows.
• (2025-08-07) Cody Koffman: Honestly, I dont really write reviews...but I felt compelled because I use this Eightify so much. It is alway reliable, dependable, and accurate. I wish it was incorporated into the youtube app on my iphone, but thats ok. great job Eightify
• (2025-08-06) Marc Hoppers: I'm a huge fan of Eightify. I've inserted this into my research workflow. I can get through lots of speeches and lectures, and it's dramatically accelerated my prep for meetings and my ramp time for new topics. I use it across several workflows for my business.
• (2025-08-03) Craig Rothwell: I was hesitant in another extension that promised to speed things up, but this truly does. It makes you aware just how many YouTube clips you consume each day when it quickly summises what's ahead and is also great for looking back on so you can review. Worth every penny.
• (2025-08-01) Alan Botvinick: A great tool that has been a real time saver.
• (2025-07-30) Kellan Hannah: Beyond helpful! This is a must-have tool for anyone in marketing, social media, and content production.
• (2025-07-29) William Peck: This app has helped me more than I can express. As someone with double deficit dyslexia and severe ADHD, it has transformed my entire learning and performance experience. Eightify and Speechify are two apps I truly couldn’t do without. Eightify allows you to review and test your understanding of information presented in YouTube content, making it easier to absorb and reflect on what you’ve learned.
• (2025-07-28) Jane Wardle: handy tool
• (2025-07-27) John Makohen: Been using this app for several years now. Most of the time, the summaries are spot on. But once in a while the summary is sparse. But thats life. Great app. Recommend to anyone who cant stand trudging through all the fluff in most YouTube videos.
• (2025-07-27) Korwin Bieniek: Really good tool. The best summarizer there!
• (2025-07-25) Marco Ahlgren: Very helpful when researching topics, and copy pasting into LLMs and Notebook LM etc
• (2025-07-22) David Leslie: If you are wondering, it is subscription based and $9.99 a month - they hide the price until after install and signup.
• (2025-07-22) Camille Mendoza: Wonderful experience so far! Speeds up my workflow
• (2025-07-19) Василий Чижиков: I just started using it, but I already felt the convenience. It really speeds up the process of receiving and assimilating information. I immediately have a number of suggestions for further development of the project: 1) Make it possible to change the language of the output in the settings, so as not to waste additional time on additional translation. 2) If possible, add timing so that you can quickly go to the place where it was said. 3) Add the possibility of an additional clarifying prompt, which would be taken into account when creating a summary. Perhaps this will help clarify what you want to summarize from a specific video. In any case, thank you very much for the service and good luck to you!
• (2025-07-08) Janac Meena: On their landing page, there's no mention of pricing/subscription costs (https://eightify.app/), but then after you install you have to pay.
• (2025-07-07) Jason De Souza: This has been great!
• (2025-07-07) Khalid Pervez: Very impressed at the accuracy and the speed of summary of a given video. Great Product / Service!
• (2025-07-04) Thanh ta C.: Garbage. have to pay.
• (2025-07-02) rick tec400: No Way In Hell would i ever trust any company with my credit card and risk credit card fraud, I.D. thieft, for a Demo! If i can't see your program or service without wasting time and risking time and money, to battle fraud, Your not worth it.
• (2025-06-29) Janet Stout: It works pretty well however it has been inaccurate in some of the things it summarized. In one instance, it said a candidate in an election was a convicted felon, however that was wrong. She was arrested protesting which is a misdemeanor not a felony. That is a very serious mistake and I didn't read that part and it caused an issue in a report I was making. I have found it made other such mistakes as well. It did not have the discernment to tell the difference between certain things. I imagine as AI improves that will be corrected, but I urge everyone to carefully go through the summary for any mistakes of this nature and not to assume what it says is entirely accurate because it cannot differentiate certain things as of yet.
• (2025-06-29) Martin Thomas: Works very fast and gives a good summary, better than any other AI video sumeriser I looked at. My only gripe is that it is jot available (yet?) for Firefox.
• (2025-06-26) Rain Drops: Good but when I resize the browser window it will remain on screen, thus not allowing me to see the video because it the video is cut off.
• (2025-06-23) Nicholas Zachary: A huge time-saver, it does what it says it does, and is worth every penny, based on my few tests.
• (2025-06-10) Faiz Aslam: Great time saver! I go through my watch later list and get summaries instead of watching the whole video.
• (2025-06-10) Javairia Bilal: This tool has been saving so much of my time! Incredibly fast and efficient. Would definitely recommend the investment
• (2025-06-08) Josh Wilson: Edit: the transcripts are all in Arabic now, even though the setting is English. ------------------------------------------------------ I compared the results from a few transcription extensions, and Eightify was the most accurate (notes below). Yes, it costs money if you want more than one per day. You get what you pay for! --- ChatGPT analysis: How Free Tools Compare to Eightify --- -Eightify (paid or free version) applies AI-driven summarization and refinement, making transcripts clearer, more structured, and more accurate. -Free tools mostly provide raw transcripts with errors and require manual cleanup.
• (2025-06-07) Laurie Williams: Great tool. MY time is very limited and this allows me to get the overview of the video, so that I can drill into what I need to fully watch.
• (2025-06-07) jilson joseph: Wouldn't recommend this, They don't even allow you to try the product on a single video without giving your card details.
• (2025-06-05) Sam Wilkinson: One of the best tools. Probably also the simplest, that I've used of late. but it has super powered the way that I work and get through so much more than I used to. it's just part of a long process now but an integral part
• (2025-06-03) Dez H: It has saved me months of learning and as an auto-didact it has been such a blessing to leverage this tool and it just works.
• (2025-06-02) M D: I've been trying to keep up with AI news and most videos have a few keys points, but take 20 mins to make them. This allows me to cut through that huge volume of videos, and work out which ones are worth watching.
• (2025-05-30) Ankur Gupta: Simply excellent and awe-inspiring
• (2025-05-28) Brent Porter: Nice to get a quick summary!
• (2025-05-25) helix monkton: Eightify is a really useful tool! I use the timestamped summary to quickly locate segments within a video that I found interesting. It's also a great time-saver when I don't have time to listen through an hour long video, I can scan ahead using the summary and quickly get the TLDR on a subject.
• (2025-05-21) EMON HOSSAIN: Eightify is super handy! It saves me time by giving quick, clear video summaries. Sometimes it misses small details, but overall I really like using it.
• (2025-05-20) Hal Hoodwin: This tool is a massive time-saver and provides insights into videos I might not have otherwise noticed.
• (2025-05-19) Shyam Sundar G V: good good good
• (2025-05-15) Zelalem Getahun: It has a good summary along with great UI. I like the highlights and icons.
• (2025-05-12) Tim: Aamazing app. Provides ton of extra insight for someone who sometimes just needs quick information to confirm understanding.
• (2025-05-10) Anne-Mieke Bovelett: I'm really happy with this!
• (2025-05-10) Ryan Noonan: 1. The summaries are not good at all 2. They charge for a service that you can easily replicated for free. If you want to do this yourself. just copy the captions of your youtube video and put them in chatGPT. Its not like this extension looks at the video at all (From what I can see), and the summaries are thematic more than chronological, the summaries dont understand anything. ChatGPT (OR deepseek, gemini ... ) gives far better sumamries, for free. Dont use this.
• (2025-05-09) En théo2: Don't download, it's a trap. They force you log in with your Google account (and they require to see some of your personal data) and then only after show you it's free for 7 days only. The other positive comments are probably fake.
• (2025-05-09) Franz Höpfinger: Helpful, but i have a lot suggestions to improve. pls contact me anytime !
• (2025-05-06) Reidmoto: I do so much research on so many AI topics and don't have time to watch a long YouTube video. I would much rather read the very well developed summaries that Eightify creates for me and save the video to Google Keep in case I do want to watch the whole video and screenshot high-value images. 5.6.25 Update: I've been using Eightify for nearly a year now, almost daily. My study workload has increased, so I had to ramp up my study process. For the past few months, I create a Google Doc and copy and paste the description, Eightify summary, and transcript, of multiple YouTube videos on the same topic. I send it to ChatGPT 4o in the chat with a prompt like this. "Please read the PDF I've attached that has multiple transcripts and summaries on Ultralearning, and summarize the main points made by the video and your own opinions please." If I submit a G-Doc with five video transcripts, summaries. and descriptions, I will get one long report with the main points broken down and explained to me, and the most important concepts and whether it agrees or disagrees with the videos, and why. It's a HUGE timesaver for me, and makes school way more fun and less stressful. My grades have also improved too!
• (2025-05-04) Chris: NO. Annoying loop to sign in, only one free summary per day, it's basically useless unless you pay, but you have to give your Google info before you find out payment is necessary to use more than once a day. Definitely not.
• (2025-05-01) Tim Halecky: Massive stack for learning new topics. Great job Eightify team! Keep up the great work!
