FAQ · How this weekly AI ranking works

  • 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 37 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?

    Writefull climbed 21 spots to #22 — the sharpest rise of the week. Linguix Business 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?

    The line under the title summarizes the run: the week, the number of tools ranked, and the AI model and country behind the answers. Table rows show weekly movement (▲▼), DECA Score, and Mention Rate. The top eight appear first, and Show all expands the list. Filters cut the list by segment, and the week selector steps back through history. Open the Weekly Breakouts tab to see which tools climbed this week and what they changed on their pages.
