I Tested 18 Free Job Search Tools in 30 Days — Only 6 Were Worth Reopening

A quick honest follow-up to 7 Free Job Search Tools That Actually Work in 2026. That post got people asking the obvious question: "OK, but what about all the other free tools out there?"

So I spent the last month opening every free job search tool I could find, using each one on a real application, and writing down what happened. 18 tools tested. Most of them I closed and never reopened. Here's the honest sort.

How I tested

For every tool, same protocol:

Use it on the same real job posting (a senior backend role at a 200-person fintech).
Use it on my real resume (no fake placeholder text).
Note the time-to-result.
Note whether the result actually changed anything I would do.
Wait 7 days. If I never reopened it, it failed.

"Free" had to mean actually free for the testing flow — no "sign up, give us your email and phone, then we paywall the result" tools.

The 6 that survived

1. Resume Checker (charliemorrison.dev/resume-checker)

The one I built. Bias acknowledged. Reason it survived my own filter: I kept opening it before sending real applications, not just to test it. Specifically the keyword-density read — it caught two skills I had buried in a project description that should have been in the top section.

Time-to-result: ~30 seconds.

2. Job Description Keyword Extractor (charliemorrison.dev/job-keywords)

Also mine. Same honesty test — would I keep opening it after the test month? Yes. Specifically because skim-reading a 600-word JD takes me 4 minutes and missing one phrase has cost me callbacks. Pulling the top 25 keywords in 5 seconds replaced my highlighter habit.

3. Resign.com salary data

Free, no signup, fast. The percentile breakdowns by city actually match what people quote in private conversations, which is more than I can say for most salary tools. Deeper dive in What Remote Developers Actually Make in 2026.

4. Otta (now WelcomeToTheJungle US)

The job board itself qualifies as a tool — the filter granularity ("no whiteboard interview", "async-first", "4-day week") saves more time than any resume optimizer. For senior roles only; mid-level inventory is thin.

5. Wellfound (formerly AngelList)

Free side: salary + equity range posted before you apply. That alone is worth the click. Don't bother with their AI matching though — it sent me three roles in industries I had explicitly excluded.

6. Hemingway Editor (free web version)

Not a job tool, but I used it on every cover letter and message. Cuts adverbs, flags passive voice, lowers reading grade. My response rate on cold messages went from "basically zero" to "about one in twelve" after I started running them through it.

The 12 that didn't survive

Quick verdicts. I'll spare the names of the worst offenders (some are legitimately new and might improve).

3 "AI cover letter generators": All produced the same 4-paragraph template with my name swapped in. One was caught by the recruiter; she replied "this is the third version of this letter I've seen this week." Killed the application instantly.
2 "resume scoring" SaaS free trials: Both gave me a number with no explanation. "You scored 67/100." Cool, what do I fix? No answer without paying $19/month.
1 LinkedIn headline generator: Outputs were grammatically fine and emotionally dead. "Driven Software Engineer | Passionate about Code." The same headline 30 million people have.
2 interview prep "AI mock" tools: Both insisted on keeping the camera on and recording. Hard pass. (My homemade alternative: open Charlie's interview prep tool, generate questions, answer them out loud into a voice memo, replay.)
1 "AI job match" extension: Crashed Chrome twice and showed me a job in Singapore when my filter said United States only.
1 networking message generator: Produced sentences that contained the word "synergy" unironically. No thank you.
1 portfolio site builder: 6 hours to set up, no flexibility, and the resulting site couldn't be exported. Custom domain was paywalled.
1 "AI follow-up email" tool: Wrote follow-ups so sycophantic they read like ransom notes.

What actually moved the needle

If I had to pick the two free things that genuinely changed my outcomes:

Keyword extraction → resume rewrite, per role. The 5-minute version of "tailor your resume" that everyone tells you to do but nobody actually does because it's annoying. Tools that automate the first 80% of this (extract keywords, show me what's missing) are the only ones I kept.

Job board with honest filters. Most boards say "remote" and mean "remote within driving distance of headquarters". The few that let me filter on the things that actually matter (async, no-whiteboard, real benefits) saved me hours per week.

Everything else is decoration.

The pattern

Free tools that survived had two things in common:

They produced something I could use in 60 seconds or less. No setup, no wizard, no "upload your resume to begin onboarding."
The output was specific, not generic. "Add 'Kubernetes' to your skills section" beats "Your resume could be stronger."

Free tools that died had the opposite — long onboarding, generic output, or a paywall hiding behind the "free" label.

What's next on my testing pile

Seven more in queue for May. If you've been burned by a tool I should warn people about (or saved by one I missed), drop it in the comments — I'll add it to the test list.
