Which AI writing assistants does ChatGPT recommend this week?

This week ChatGPT names Grammarly more than any other AI writing assistant — DECA Score 100.0, out of 49 tools tracked. The table above has the full field, from long-form drafting to brand-voice tools.

How is this AI writing ranking calculated, and how often does it update?

Weekly, we ask ChatGPT what writers and marketers typically ask — best AI for long-form drafts, which tool keeps brand voice consistent — and measure every assistant it mentions, by frequency and prominence. See the methodology for the scoring mechanics.

What changed in this week's AI writing ranking?

Wordtune climbed 18 spots to #20 — the sharpest rise of the week. Movieball entered the chart for the first time.

Does ChatGPT recommend its own competitors as writing tools?

Yes — and that is what makes this chart interesting. Asked about writing tools, ChatGPT regularly names competing AI assistants alongside grammar checkers and long-form editors. We simply measure that behavior, week after week.

How do I get the most out of this chart?

Signal cards summarize the week — Leader, Top Mover, New Entry. Table rows show weekly movement (▲▼), DECA Score, and Mention Rate; filters cut the list by segment, and the week selector steps back through history. If a tool you use is missing, add it free.
