I uploaded my application to various websites like Indeed, LinkedIn, places like that, and I was not getting anything that was in the field that I wanted to be in. I put my information in rezi, and I was able to reorganize my experiences and come up with better bullet points for some of my volunteer experiences that were in that field. And now in the past week I've had like five interviews, and I was able to secure a part time job doing something in that field.

For some reason, I struggled a lot with choosing a format for my resume, and then managing that format when I wanted to make updates. With Rezi, I was able to simply input data, check out the preview, and know that it will be formatted correctly when I export the resume to Word. Rezi made it super easy to refine and iterate on my resume. There are alot of options for resume writing, and if you are reading this on the fence about whether to try Rezi, just do it. A simple, fast, well-designed resume tool.

Just what I was looking for

Rezi is now the only place I edit my resume (I've ditched the Word doc I used to use), and I honestly believe that using Rezi has allowed me to create a much better resume than I would have on my own. I intend to keep using it and experimenting more with the AI generation for customizing the resume to different jobs.

Very good resume editor!

Some difficulties that I faced when creating a resume, initially was formatting. Another feature that I've actually found myself using more often than I expected was the professional resume reviews. Other options that I tried in the past, some like, free alternatives. Some of them wouldn't let you say your resume or came with some unexpected strings, but Rezi is super upfront and continues to improve over time. I've recommended Rezi to several of my friends and colleagues who will continue to do so. I just love this product so much.

Not a paid promo. I've been looking for a change of jobs for almost a year. Got a few calls, but nothing what I wanted. Updated my CV through Rezi, the second call I got was from an MNC and something I was looking forward to. And here I am, completing my second month at the new place. I checked with my HR how she found me - it was through the Rezi cv (I had to check because I used to apply with my old CVs as well)Thank you, Rezi. Thank you, Jacob! Yes the UI, formatting, keyword suggestions etc are all great but the best of all - dedicated customer service.

Rezi worked like a charm.

... I created a few primary versions of my resume and then would copy them and use Rezi to suggest content for each job description. Rezi was helpful by comparing my resume to the job description and making suggestions for extra keywords. Using Rezi for this instead of doing it myself reduced my time per application from 1-2 hours down to 15 minutes. The response I got from applications with targeted resumes and cover letters using Rezi was high.

My experience with Rezi during a job search.

Rezi has been instrumental in a job search I've participated in in two specific instances. Number one, as my own personal resume customization tool. Searching through thousands of different job descriptions as an MBA student, Rezi really helped me reinforce my resume or customize my resume for the job descriptions I thought were most important. And was a great support tool on top of what I already received as a part of a full time MBA program.

UI: Firstly, the UI is a breeze. It's real fun to use, and what I like most is the fact that the application divides your resume into different sections, and you get to work on each section at a time. Psychologically, this helps you alleviate anxiety and just work on one thing at a time.
‍Formatting: Trying to format your resume on Google Docs or MS Word or even Latex can be a hassle more often than not. REZI.AI does your formatting like a charm. There's a handful of nifty features like the auto-tune (which automatically adjusts stuff), borders, accent colors and others.
‍ATS Scoring: This is perhaps the USP of REZI. You can target a resume for a job description and view the score corresponding to that particular application.

Very Reliable Resume Editor

I've used many different resume building webistes, all of them ended up wanting more and more money. Rezi on the otherhand has the lifetime option which allows a good taste of what it could do. But overall it is nice and clear what I am supposed to do and love the PDF download option. Not many templates but they are all simple and to the point. Thank you for creating and offering this as a service!

It aligns your skills and experience with the job description effectively.

What’s the best way to use an AI resume builder?

To get the most out of an AI resume builder, either start from scratch or upload your current resume.

This personalization allows the AI to build a unique and tailored resume that’s bound to catch potential employers' attention.

Aren’t all resumes written with AI super similar?

AI-generated resumes can seem similar if you're not giving personalized inputs or if you're using basic prompts. Provide specific details about your work experience and target the job you’re eyeing. Use specialized AI tools instead of general chatbots to avoid robotic-sounding resumes and to ensure individual creativity.

Will employers know I used AI to write a resume?

Employers might think you used AI, but that’s rarely an issue. What they really care about is getting a well-written resume that showcases your skills and experiences accurately. A top-notch resume tailored to their needs will speak volumes more than worrying about AI involvement.
