Hemingway Editor and AI grammar checkers are often listed as alternatives, but they solve different problems. Hemingway is a readability coach: it highlights hard-to-read sentences, adverb density, and passive voice, and gives your text a grade level. It does not attempt full grammar correction. AI checkers do the opposite: they find concrete errors but rarely coach on style. Here is which tool fits which job - specifically for developer writing.
What Each One Does
| Capability | Hemingway Editor | AI grammar checker |
|---|---|---|
| Agreement, tense, spelling | Not its job | Core feature |
| Readability grade | Core feature | Usually secondary |
| Passive voice / adverb highlights | Yes, visual | Varies |
| Handles code blocks | No - paste code and it scores it like prose | Code-aware ones: yes |
| Rewrites meaning? | No | Good ones: no; raw LLM passes: sometimes |
The Developer Angle
Hemingway's color-coded density view is genuinely useful for READMEs and tutorials - long, tangled sentences are the top readability killer in technical docs. But paste a section containing a code block and every line of code gets scored like a sentence, pushing the grade level into absurdity. There is no "skip code" mode.
An AI grammar checker with code awareness takes the same document and simply excludes code from analysis - see Lint's grammar checker - and pairs it with a deterministic readability score that ignores code lines: Lint readability analyzer. That covers both jobs in one pass, in the browser.
Practical Pairing
- Short prose (emails, PR descriptions): an AI checker alone is enough
- Long tutorials: run a readability pass (Hemingway or equivalent) plus a grammar pass
- Docs with heavy code: use code-aware tools, or you will fight false positives all day
