Questions this page answers
- Best draft of a blog post or email in my voice?
- FitForTool has not published a FitScore for this job. The launch candidates are Claude, ChatGPT, Gemini, Grok, Jasper, and Grammarly. Each one is listed as not yet tested. A ranking is published only after every tool in the comparison has had the same test pack run, and a person has reviewed the result. Until that page shows a FitScore, there is no winner.
- How will FitForTool test writing assistants?
- Brief + 2 voice samples. One brief (a blog post or an email, chosen in the pack and used for every tool) and two writing samples. A person checks whether the draft does what the brief asked and whether it resembles the samples rather than a default assistant voice. There is no hidden brand-voice score. We record brief followed, voice notes, human edits, time, cost, version, and plan. Those notes are then scored from 1 to 5 on seven shared criteria. The pack has been specified and has not been run.
- Can a vendor pay to rank higher on this job?
- No. FitForTool does not sell position or score. A sponsorship, if we run one later, is labelled and sits outside the ranked list. An affiliate link is disclosed and does not change order. A vendor may ask for a retest, and we rerun the same pack. Sponsors do not see the result before it is public.
- What does "Not yet tested" mean?
- The tool is a candidate for this job. There is no published hands-on run, so there is no FitScore, no criterion score, and no rank. Research-only is a different label, used when we have read the docs and still have not run the pack. Neither label is a score.
