FIRST-HAND TEST

What we tested directly

Small-business homepage copy from constrained facts

Tested Sep 16, 2026 · 3 identical-prompt runs
First-hand test

Across three identical logged-out runs, ChatGPT produced clear, usable first drafts that retained the supplied service facts and kept every subject line within the requested limit. It missed the 120–150-word instruction in all three runs, and one run added an unsupported simplicity claim. The result supports using the tool for fact-grounded first drafts only with a human checking every constraint and claim.

Task
Create a short homepage section and three email subject lines for a fictional bookkeeping service while using only supplied facts.
Access
Logged-out ChatGPT web experience in three separate desktop browser tabs. No account, files, follow-up prompts, personal data, or confidential business information were used.
Model/version
The logged-out interface did not disclose the model or product version used for these responses.
Measurement
Word counts treat tokens separated by whitespace or punctuation as words and keep contractions as one word. Subject-line character counts include spaces and punctuation.

Expected result

  • A homepage section between 120 and 150 words, including its headline and call to action.
  • All four supplied service facts represented accurately.
  • No prohibited or unsupported business claims.
  • Three subject lines under 45 characters each.
  • Clear, calm, practical language for the stated audience.

Human review required

  • Count the words and characters instead of assuming format constraints were followed.
  • Compare every factual statement with the approved source facts.
  • Remove or substantiate benefit and process language that was not provided.
  • Edit repeated calls to action and choose the version that best matches the brand voice.

Observed

  • The homepage section measured 95 words across the headline, body, and call to action, below the requested 120–150 words.
  • All supplied facts appeared.
  • Subject lines measured 36, 36, and 39 characters.
  • The phrase ‘No complicated process’ was not supported by the supplied facts and would need removal or substantiation before publication.

Meaningful variation

  • Homepage-section length increased from 58 to 73 to 95 words, but no run reached the requested range.
  • The headline stayed nearly identical, while calls to action and the first two subject lines varied.
  • The third subject line was identical in all three runs.
  • Only the third run added a clearly unsupported process claim.

Limitations

  • One fictional writing task cannot establish overall writing quality or performance on other business work.
  • The model and version were not disclosed in the logged-out interface and may change without notice.
  • The test did not cover account features, memory, file uploads, research, privacy controls, or paid-plan capabilities.
  • Timestamps document the capture window; they are not a latency benchmark.
  • No competing product was tested, so this record supports no comparative ranking.

Small-business homepage copy: September 17 retest

Tested Sep 17, 2026 · 3 identical-prompt runs
First-hand test

This same-brief retest produced 108, 91, and 128 homepage words; only run three met the requested 120–150-word range. All supplied service facts appeared and all nine subject lines were below 45 characters. Run one repeated an unsupported process claim, while runs two and three added audience assumptions. These results support a reviewed drafting workflow, not unattended publication or a product-wide rating.

Task
Create a short homepage section and three email subject lines for a fictional bookkeeping service while using only supplied facts.
Access
Logged-out ChatGPT web experience in three new conversations in separate desktop browser tabs using the same browser profile. No account, files, follow-up prompts, personal data, or confidential information were used. Run two displayed an optional sign-in prompt after generation; it was dismissed without signing in. Separate tabs are not isolated browser profiles.
Model/version
The interface did not disclose the model or product version. Do not attribute these outputs to a named model or paid plan.
Measurement
Uses the same word-count expression as the September 16 record: alphanumeric/currency tokens, keeping internal apostrophes and hyphens. Count the headline, body, and CTA, including any generated “Call to action:” label; exclude interface labels and the email section. Subject characters include spaces and punctuation. Submission and completed-output observation timestamps bracket the capture window, not generation latency. Wording and punctuation are preserved; display markup is normalized to paragraph breaks.

Expected result

  • A homepage section between 120 and 150 words, including its headline and call to action.
  • All four supplied service facts represented accurately.
  • No prohibited or unsupported business claims.
  • Three subject lines under 45 characters each.
  • Clear, calm, practical language for the stated audience.

Human review required

  • Count the words and characters instead of assuming format constraints were followed.
  • Compare every factual statement with the approved source facts.
  • Remove or substantiate benefit and process language that was not provided.
  • Edit repeated calls to action and choose the version that best matches the brand voice.

Observed

  • The homepage section measured 128 words, inside the requested 120–150-word range.
  • Subject lines measured 34, 35, 34 characters; all were under 45.
  • All supplied service facts appeared.
  • The copy adds an unsupplied audience characterization about being busy with clients.
  • The consultation invitation and final call to action repeat the same next step.
  • The final ‘Call to action:’ label is included in the word count; interface headings and the email subject section are excluded.

Meaningful variation

  • One of three new runs met the word range, unlike the September 16 session where none did. These are repeated observations of the same task, not independent task coverage.
  • All three headlines were the same; body length and subject wording varied.
  • Run one said “No complicated process”; runs two and three instead introduced unsupplied descriptions of a busy audience.

Limitations

  • One synthetic brief repeated in one browser profile cannot establish general writing quality, comparative superiority, or a reliable pass rate.
  • The access condition and undisclosed model may differ from signed-in or paid experiences.
  • No paid-plan features, privacy controls, uploads, research, memory, real customer outcomes, editing time, or conversions were tested.
  • No revision prompt was tested; advice about manual review is editorial interpretation.
  • Timing records capture observation windows, not a speed benchmark.
