Hi J_H, this issue should be resolved now. Thanks for bringing it to our attention!
Q: Free trial review
It's not bad, I like the source detector. The AI detector also does it's job somewhat ok-ish.
I did 3 ai detection, about 500 words and 3000 characters each. They used up around 600 to around 500 credits for the detection. For the first one, it was fully AI generated by ChatGPT, I got a 93.70% confirmation rate, and source detector was OpenAI, no questions there. For the second one, I changed it and added mimimal human text, I got a 72.10% AI generated. Again, no issues and works perfectly. But for the last test, I used an AI humanizer tool and immediately, the tool put it as 11.95% AI generated. This was a huge jump so I think the devs might have to work a bit on that. But again, the tool is good enough to use when you need a "quick is this AI check" before you submit something w/o the need to purchase premium plans of GPTZero.
A: Thanks for the detailed review! Our models are continuously evolving to keep pace with new humanizers (which also evolve) so you will see improvements on that front. Again, thanks for considering Polygraf and giving us a shot!
@J_H: I see this similar and have same false/positive results as well. Overal I think the system gets better and hopefully will learn to improve the AI detector and humanizer. Kepp up the good work @Vignesh_PolygrafAI :)
Q: History Function [BETA] wants to delete the selected history.
History Function [BETA] I would like your help to improve it so that users can select specific items to delete or choose to delete all.
Q: Will premium features ever be added to standard plans?
Will only be interested in purchasing if I have your word that in the future that premium features would released to your standard plans too. Right now everything seems super restrictive.
A: Hi there. Some of the Premium plan features, especially those involving advanced content analysis/generation and deeper AI detection, are extremely GPU-intensive and resource-heavy. We’re actively working on optimizing and deploying token usage efficiency upgrades shortly to make these features (and more) more accessible to other plans, so more users can try everything and grow from there....
Is this tool meant to be in other languages, or is its focus mostly on English? I wanted to check Serbian, and even when I add the content created with AI, it shows that it is 99+ human. I need to know this because without support for other languages makes this tool unusable for my needs. Free online alternatives (without marking parts of the text) support Serbian without any problems, so it is strange to me why it only works with English.
A: Hi there, Thanks for your question. Polygraf’s language support presently varies by feature: • AI Detection - Currently optimized for English only (road-map currently includes Spanish and Japanese). • Humanizer - English only at this time (road-map currently includes Spanish and Japanese) • Content Writer - Works with virtually any language that uses UTF-8 characters; customers have...
