If you have ADHD and struggle with workplace communication, you've probably tried Grammarly. It fixes your spelling. It flags awkward sentences. It suggests synonyms. And yet somehow, the email still doesn't get written.
That's because Grammarly and Commly Professional solve fundamentally different problems. This comparison explains what each tool actually does, where each one falls short, and which one addresses the specific challenge that ADHD creates in professional communication.
What Grammarly Does
Grammarly is a writing assistant that checks and improves text you've already written. It catches spelling and grammar errors, suggests tone adjustments, flags passive voice, and recommends clearer phrasing. It integrates directly into email clients, browsers, and document editors, giving you real-time feedback as you type.
Grammarly is excellent at what it does. For professionals who write fluently and want to polish their output, it's genuinely useful.
The core assumption Grammarly makes: You can write something. The text exists. Grammarly makes it better.
Why Grammarly Doesn't Solve the ADHD Problem
ADHD workplace communication challenges aren't primarily about grammar or word choice. They're about initiation.
The blank email compose window is a starting problem, not a writing problem. Executive dysfunction — the ADHD experience of knowing what you need to do but being unable to start doing it — means the text never gets written in the first place. Grammarly has nothing to work with until the text exists.
More specifically, Grammarly cannot help with:
Task initiation. Grammarly sits in your browser waiting for you to type. It does not help you begin.
Emotional regulation in writing. When an email carries emotional weight — a difficult message, a long-overdue follow-up, a conflict that needs addressing — ADHD brains often freeze entirely. Grammarly corrects grammar. It doesn't help you process the emotional dimension of what you're writing.
The prompt problem. Grammarly's AI writing features still require you to describe what you want. "Help me improve this" assumes you have something to improve. "Write me an email about X" is still a blank prompt requiring you to articulate your needs precisely.
Structured output. Grammarly returns edited prose — the same format as your original text, just cleaner. For ADHD professionals who process structured information more easily, returning a wall of polished prose still requires significant cognitive effort to evaluate.
What Commly Professional Does Differently
Commly Professional starts from the assumption that the blank box is the problem — not the words inside it.
The Paste & Slide workflow removes the initiation barrier entirely. Instead of opening a blank email compose window, you open Commly Pro, paste whatever you have — a rough thought, an unpolished paragraph, a stream of consciousness — and adjust three sliders for tone, formality, and directness. The tool generates a structured, professional output from whatever you gave it.
The starting point is always something you already have, not a blank page.
What this means for ADHD professionals specifically:
- —You bypass the initiation barrier by starting from a rough draft rather than nothing
- —You don't need to articulate precisely what you want — the sliders replace the prompt
- —The output is always structured — bullet points, clear paragraphs, formatted email — not prose that requires further processing
- —The tool is consistent and predictable — it works the same way every time, which reduces the cognitive overhead of deciding how to use it

Which One Should You Use?
The honest answer is that they solve different problems and aren't direct competitors.
Use Grammarly if: You can write fluently and want a polish layer — catching typos, adjusting tone slightly, improving sentence structure. Grammarly is excellent at this.
Use Commly Professional if: The problem is starting. If emails sit in your drafts for days, if you stare at blank compose windows, if the cognitive cost of professional communication is disproportionate to how capable you are — Commly Professional addresses the root cause.
For many ADHD professionals the ideal workflow is both: Commly Professional to get from blank page to structured draft, then Grammarly for a final polish pass before sending.
The Bottom Line
Grammarly assumes you can write. Commly Professional assumes you need help starting.
If your professional email problem is typos and tone — Grammarly is your tool. If your problem is that the email never gets written — Commly Professional removes the barrier that Grammarly doesn't address.
