How to get the most out of the grammar checker
This tool finds errors fast, but you get better results when you set it up right and review the changes with intent.
Set your writing goal before you paste
The grammar checker adjusts its suggestions based on whether you pick general, academic, business, casual, or marketing. Academic writing flags contractions and informal phrases. Marketing mode tolerates sentence fragments and direct address if they add punch. Business catches overly casual language.
If you leave the goal blank, you get general-purpose fixes. That works for most cases, but targeting your audience first means fewer false flags and more relevant clarity tweaks.
Pick your English dialect to avoid false positives
American English spells 'color' and 'analyze'. British English spells 'colour' and 'analyse'. Canadian mixes both. Australian follows British but has its own quirks. Set your dialect so the tool stops marking correct regional spelling as errors.
This matters most for client work, academic submissions, and anything published in a specific region. One mismatched dialect setting can fill your results with dozens of fake corrections.
Read the explanations, not just the fixes
Every correction includes a plain reason: 'Subject and verb must agree in number', 'Passive voice makes the actor unclear', 'This comma splice joins two independent clauses incorrectly'. Those explanations are the tool's real value. You learn grammar rules in context instead of memorizing abstract lessons.
After a few rounds, you will start catching your own repeat mistakes before you paste. That is faster than running every draft through a checker.
Add the tool to your workspace for team style guides
The free version gives you 3 checks a day with no signup. Inside a Letaido workspace, the daily limit and the 1,000 word cap are lifted, you can set a custom brand voice so corrections match your house style, and you can chain the grammar checker with other tools like the AI rewriter or headline analyzer.
If multiple people write for your brand, a shared workspace keeps everyone using the same dialect, tone, and style rules. One source of truth, zero style drift.
