- Bro I low what you have built but I installed in edge. I was working on website suddenly i don't see gradients and colors after thinking deeply i found this extension is causing the gradients working properly I uninstall it. I am still giving 5 stars for your idea, but you should fix these so others might not get into that problem. Just for your test open the website https://fluxresume.io and see with extension vs without extension

- Like it on Chrome, any chance this is coming to Firefox?
- Karthik Pasupathy
- A really useful product that works on all the apps. The best thing is, the team behind the app is really responsive and immediately works on user suggestions.
- Antonio Cangiano
- I don't understand why this extension has received such low ratings from others. It has been an excellent addition to my workflow. The extension functions flawlessly and has an elegant design. By combining it with a custom system prompt I developed and using the convenient Option+W keyboard shortcut, it has significantly boosted my productivity for my specific use case. I'm impressed with it, and after just 2 minutes of use, I was convinced to upgrade to the pro version.
- Vikash Kumar Prajapati
- Exactly what I needed.
- Dashing Gamer
- Great and useful Extension! Go for it!
- amiel pineda
- Ignore those who gave 1-star reviews, just install it first yourself and you'll see how useful it is. It even downloads the free gemini nano locally so you can run it without internet. Super cool app, would buy the pro version to support. Keep it up!
- Anna St
- Great extension! Developer was very responsive and even added extra functionality upon my request within literally a few days.
- Fani Faisal
- So far, it's the best browser extension I've tried. It really helps with grammar checking and improving my writing. I have tried different extensions, but they are too complicated to set up and use.
- sarvesh kumar
- Can't believe how good this thing is—one flat price and boom, any API plugs straight into OpenRouter. Total game-changer, wipes the floor with Grammarly
- Vilok reguri
- This extension is a good alternative to Grammarly, and I'd love to see more features added. btw this comment is written by Wandpen
- Rational Human
- Unable to use Gemini Nano. It shows an error that 'You can't use Gemini Nano at the moment, please check your disk space. Or make sure you are on Chrome version 138.'. I am have plenty of disk space and I am using Chrome 138
- eltLeyz
- You can't use it for free and they also ask you to log in to collect your data.
- Ethan Lee
- Really good extension! Gemini Nano works blazing fast on Wandpen and love how there are different options, such as my favourite one: 'Expand this idea'. Anyways, 5 stars on this extension!
- DarkView AI
- Needs an account to use it. Don't recommend using it.
- Ellis Crosby
- Really helpful app! Helps me get through writers block
- Corbett
- You need an account to use it. Can't even use the locally installed gemini nano without an account. Got to love all the data collection and annoying account creation just to use a small grammar correction extention.
