02The detail

How the five criteria turned into one number

A rating without a method is an opinion with a star on it. Here is how we built ours.

Our dirty chat ratings start with five criteria: conversation depth, tone control, privacy, free-tier value, and character variety. Each is scored on a five-point scale by the review team, independently of the others. The final rating is a weighted average — not a rounded-up guess designed to look good on a search result.

Conversation depth carries the highest weight because it is the reason people stay. A chatbot that replies fast but forgets your name after one session is a toy, not a product. Tone control and privacy carry equal weight because they are the two things that make an adult product usable in practice: you need to set the register you want, and you need to trust that nothing leaks.

Free-tier value and character variety carry the remaining weight. A generous free tier earns a high mark because it lets you make an informed decision. Variety matters because a roster of identical personalities with different faces is not variety — it is a skin pack.

What works well

  • Each criterion scored independently before weighting
  • Method published alongside the rating — not hidden
  • Conversation depth weighted highest, reflecting real usage
  • Privacy audit covers contact sync, social graph, and app footprint
  • Character variety measured by personality range, not roster count alone

Worth knowing first

  • Weighting reflects our priorities, which may differ from yours
  • Every character reviewed is fictional AI, not a real person
  • The rating reflects one review cycle — scores can change with updates
  • Strictly 18+ with an age gate before any content loads

04In practice

What each score means in practice

A 4.8 on conversation depth means the chatbot referenced details from earlier sessions, unprompted, in a way that felt contextual rather than mechanical. A 4.4 on free-tier value means the free experience is real but ends sooner than we would like — enough to decide, not enough to settle in.

A 4.9 on privacy means no contact import, no social graph, no app icon, and no trace in a purchase history. That score is the highest we have given in this category, and it reflects an architectural choice, not a marketing claim.

05Quick answers

Dirty chat ratings — quick answers

01

How did you weight the five dirty chat rating criteria?

Conversation depth carries the most weight because it is why people stay. Tone control and privacy are equal. Free-tier value and character variety share the remaining portion. The exact weights are published in our method note.
02

Can the rating change over time?

Yes. If the product updates its free tier or memory system, we re-test and update the scores. The rating reflects a specific review cycle, not a permanent verdict.
03

Why is privacy scored so high?

Because the product does not import contacts, does not build a social graph, runs in a browser tab with no app icon, and leaves no trace in a purchase history. That is an uncommon combination in this category.
04

Do you accept payment from the products you rate?

We are an affiliate site: if you click through and upgrade, we may earn a commission. The rating method is published so you can judge whether the scores are earned or inflated. We disclose the relationship on every page.
