About LightForth

What Is LightForth

LightForth is a career app built by Lightforth Inc. It bundles the chores of a job hunt into one place: a resume builder, a cover letter tool, an ATS checker, automated job applications, application tracking, and an interview copilot that listens to a live call and feeds you talking points as you go. The company is based in Dallas, Texas.

The idea is that job seekers lose hours to scattered tabs. You draft a resume in one tool, hunt listings on three job boards, keep a spreadsheet of where you applied, and then rehearse answers alone. LightForth pulls those steps under a single login. You build job profiles, it surfaces matching listings from Indeed, LinkedIn, and Glassdoor, and it tracks deadlines and interviews without you updating anything by hand.

Three limits shape the experience. There is no free tier in the usual sense; instead you get 5 credits a month to test actions, and real use runs on a subscription that starts at a promotional $10 for the first month before renewing at $49. The interview copilot works on macOS and Windows only, so phone-only users get the resume and apply tools but not live interview help. And the product is mid-rebrand: LightForth is becoming Jobwhisper, so existing credits expire November 15, 2026.

Getting Started

  1. Create an account on the web or in the mobile app, and answer a few questions about the roles you want.
  2. Upload an existing resume or build one from a template, then let the resume builder tailor it to a specific posting.
  3. Set up one or more job profiles so the app can pull matching listings from Indeed, LinkedIn, and Glassdoor.
  4. Turn on auto-apply to send applications, and watch progress in the tracker.
  5. Install the desktop app on macOS or Windows to run the interview copilot during live interviews.

Key features

AI resume builder

You start from a template or an existing file, then paste a job description and let the career copilot rewrite the resume around it. It pulls out the keywords and skills a posting asks for and works them into your history, which is the part most people skip when they apply to twenty roles in a week. Downloads come out in the format recruiters expect.

Auto-apply for matching jobs

Auto-apply sends applications to roles that fit the profiles you set, so you aren't filling the same fields over and over. It draws listings from major job boards, then hands you a queue to review. The point is to keep several applications moving in parallel rather than one at a time.

Live interview copilot

On macOS and Windows, the copilot listens to your interview in real time and shows suggested answers on screen. It builds those answers from your resume and the job description, so the guidance sounds like your experience rather than a script. It also covers coding interviews and longer meetings, not just standard questions.

ATS checker

Before you send a resume, the ATS checker compares it against the posting and flags keywords the automated screening software looks for. Applicant tracking systems reject resumes that miss those terms, and most people never learn why. The checker tells you what to add while you can still fix it.

Application tracking

The tracker keeps every application, deadline, and interview in one view, so you see where each one stands without a spreadsheet. Status updates happen as you apply and as you book interviews, which matters most when ten applications are open at once.

AI cover letters

The cover letter tool writes a version matched to each role instead of a reusable template. You get a first draft tuned to the posting's language, which you then edit to sound like you. It pairs with the resume builder so both documents tell the same story.

Pros and cons

Pros

  • One app covers resume, cover letter, auto-apply, tracking, and interviews, so you stop juggling separate tools for a single job hunt.
  • The live copilot pulls answers from your own resume and the job description, so suggestions fit your background rather than reading as generic advice.
  • Multiple job profiles let career switchers chase two fields at once and get matching listings for each.
  • The ATS checker explains which keywords a resume is missing, which is the step most applicants skip before hitting submit.
  • It runs on web, iPhone, Android, macOS, and Windows, so the core tools follow you across devices.

Cons

  • There is no true free plan, only 5 credits a month, so you can't use the app properly without paying.
  • The interview copilot is desktop only, which leaves phone-only users without the feature the brand leans on hardest.
  • The $49 monthly renewal is steep for people who apply in short bursts and then pause.
  • LightForth is rebranding to Jobwhisper, so leftover credits stop working on November 15, 2026, and you have to create a new account to continue.
