Feature-by-feature comparison.
We compared key capabilities to help you understand which tool fits your needs best.
What the tool actually does for you
The biggest difference is not feature-by-feature. It is the shape of the product. One runs your whole job search. The other scores one CV at a time.
Karko AI
Karko runs the full loop. The Smart Job Feed finds roles matched to your CV. Fit Analysis tells you if the role is worth applying to. The generator writes the tailored CV, cover letter, application email, follow-up, and screening answers. The tracker saves every application automatically. You do not leave the app.
Rezi
Rezi is a CV scorer with good interview practice. You write the resume (with AI assist), run it through the 23-criteria Rezi Score, iterate until the score is high enough, and export. Good at that narrow job. Does not find jobs, write cover letters in the same flow, or handle emails or screening.
Why This Matters
Different shapes. Karko is the whole workflow. Rezi is a polished tool for the CV quality step plus interview prep. If you want one app for the whole job search, Karko. If you already have a job search workflow and only want to polish each CV to a score, Rezi.
Finding the right jobs to apply to
Most job seekers spend roughly ten hours a week bouncing between LinkedIn, Indeed, Wellfound, and company career pages. That is before they write anything.
Karko AI
Smart Job Feed delivers up to 25 roles a day, matched to your CV, your goals, and your location. Ranked by real fit, not keyword match. Tap any role to jump into the fit analysis and full application.
Rezi
No job discovery. Rezi assumes you have already found the role. The workflow starts after that.
Why This Matters
Karko removes the job search step. Rezi operates on a role you found yourself.
Writing the full application
One tailored application takes roughly an hour by hand. And that is just the CV. The cover letter, emails, and screening answers each add more.
Karko AI
Karko writes the full application in 90 seconds: tailored CV, cover letter, application email, follow-up, and screening answers. Every output is grounded in your real CV, with consistent voice across all documents.
Rezi
Rezi writes the CV and cover letter with AI assist, typically around 20 minutes per tailored version. No application email, no follow-up, no screening answers.
Why This Matters
Karko is roughly 13x faster on the CV step alone, and it also handles the three downstream artifacts (emails, follow-up, screening) that Rezi does not touch at all.
Fit analysis before you commit
Spending an hour on a role that was never a fit is the biggest time sink in the job search. A fit check up front changes that.
Karko AI
Before any writing happens, Karko runs a fit analysis. Half a credit gives you a match score, the skills that line up, and a clear list of gaps. You decide before spending credits on the full application.
Rezi
No fit analysis before writing. Rezi's score is a post-hoc check on a resume you have already written. A different question.
Why This Matters
Karko tells you whether to apply. Rezi tells you whether your resume passes ATS after you have written it. Karko's upstream check saves more time.
ATS scoring: default-safe vs scan-and-score
Both tools solve the ATS problem, in different directions.
Karko AI
All six templates are ATS-optimized by default: single-column layout, standard section headings, system fonts, consistent dates. Keywords from the job description are applied where you already have real experience. No separate scoring step needed.
Rezi
Rezi Score rates your resume across 23 criteria: formatting, word choice, keywords, length, metrics, section order, action verbs, and more. Detailed feedback, actionable list. You iterate until the score is high.
Why This Matters
Different approaches. If you want output that is ATS-safe without thinking about it, Karko. If you enjoy the granular iteration loop and want a numeric score to optimize, Rezi.
Application emails, follow-ups, screening answers
Recruiter emails, follow-ups, and screening questions are where most applications stall. Good tools help with all of them.
Karko AI
All three are built in. Application email with subject line and body. Follow-up email pre-drafted for 7 to 10 days later. Screening question answers on Plus and Max: STAR structure for behavioral questions, direct answers for factual ones, all from your real CV.
Rezi
None of these are offered. Rezi stays focused on the resume and cover letter.
Why This Matters
Everything downstream of the CV is absent on Rezi and handled on Karko.
Interview practice
Preparing for interviews is a separate part of the job search. Some tools handle it, some do not.
Karko AI
Karko does not offer interview practice. The product is focused on finding, applying, and tracking.
Rezi
Rezi has a genuinely good AI interview practice feature with role-specific questions and a conversational coaching agent.
Why This Matters
If interview practice is a priority, Rezi has it and Karko does not.
Trust: does the output sound like you, and is it true?
Recruiters can now spot ChatGPT output in one read. And a CV that invents experience can get you fired after you start. Trust is the new bar.
Karko AI
Every CV rewrite, cover letter, email, and screening answer is built from the CV you upload. Karko will not invent job titles, skills, or experience you do not have. The job description is used for keyword alignment and tone, never as a source of facts about you.
Rezi
Rezi's AI generates bullet-point suggestions from your job title and industry. The quality of truth depends on you accepting or rejecting the suggestions. Rezi does not have an architectural anti-hallucination rule.
Why This Matters
Anti-hallucination is architectural in Karko. It is the moat.
Pricing model
Different users want different pricing shapes. Subscriptions, credits, lifetime.
Karko AI
Free ($0, 2 applications a month), Plus ($19.99/mo, 25 applications), Max ($79.99/mo, 100 applications). Every feature on every plan. Add-on credit packs $19.99 for 50 credits.
Rezi
Free (1 resume, 3 PDF downloads). Pro $29/month. Lifetime $149 one-time. The lifetime plan is attractive if your job search is going to be long.
Why This Matters
Karko's Plus is cheaper monthly than Rezi Pro. Rezi's lifetime plan is cheaper long-term if you do not need Karko's job search features. Different buyer decisions.
Which tool should you choose?
Different tools excel at different things. Here's our recommendation based on your specific needs.
Pick Karko AI if you want one app for your whole job search
You are tired of bouncing between LinkedIn, Indeed, a resume builder, ChatGPT for cover letters and emails, and a spreadsheet. You want one loop: find, check, write, track.
Karko was built for this. Smart Job Feed replaces the board-hopping, fit analysis replaces the guesswork, the generator writes everything, and the tracker replaces the spreadsheet.
Pick Karko AI if screening questions and emails are killing your momentum
You keep reaching the screening question section on Workday or Greenhouse and closing the tab. Or you never send follow-up emails because drafting them is too much work.
Screening answers (Plus and Max), application emails, and follow-ups are all built into the Karko flow. Rezi does not do any of these.
Pick Rezi if CV score iteration and interview prep are your thing
You already have a job search process, you enjoy polishing a resume to a 90+ Rezi Score, and you want AI interview practice alongside.
Rezi is genuinely good at those two things. If that is the specific job you need done, Rezi is the right tool.
Pick Karko AI if you are applying in Europe, especially Germany
You need Lebenslauf formatting, EU-style CV conventions, and templates that pass German ATS systems.
Two dedicated German templates (German ATS, German Classic) with proper Lebenslauf structure. Rezi is US-centric.
Frequently asked questions.
Is Karko a Rezi replacement?
On the CV side, yes. Karko writes a tailored CV per role, ATS-safe by default, in 90 seconds. On the interview practice side, no. Rezi has genuinely good interview prep and Karko does not. If that is a must-have, pair the two.
Can I use Karko and Rezi together?
Some users do. Generate the full application with Karko, then use Rezi's interview practice when you hear back. Makes sense if interview prep is a priority for you.
What does Karko do that Rezi does not?
Five things: job discovery via the Smart Job Feed, fit analysis before you write, application emails, follow-up emails, and screening question answers. None of these exist on Rezi.
What does Rezi do that Karko does not?
Two things: a detailed 23-criteria Rezi Score on a finished resume, and AI interview practice.
Which has better AI for writing?
Karko runs on Claude Sonnet 4.6 by Anthropic, one of the most capable models available for writing. Rezi uses AI but does not disclose the model. Karko also has architectural anti-hallucination rules so every output traces back to your real CV.
Which is cheaper?
Karko Plus ($19.99) is cheaper monthly than Rezi Pro ($29). Rezi has a $149 lifetime plan that is attractive if you expect a long job search and only need what Rezi offers. Karko's per-application cost at Plus is about 80 cents, which includes CV, cover letter, emails, and screening answers.
Which is faster?
Karko writes the full application in 90 seconds. Rezi's typical tailored application takes around 20 minutes, and that is just CV plus cover letter. Karko is roughly 13x faster on that step alone.
The verdict.
Karko AI and Rezi are shaped differently. Karko replaces the seven tools you use to apply for a job with one loop: find the role, check fit, write the full application, track it. Rezi is a well-made CV scorer with good interview practice. Pick Karko if you want your entire job search in one app. Pick Rezi if your search workflow already works and you just want to polish CVs to a score and practice for interviews. If both matter, some users run Karko for the application loop and Rezi for interview prep.
