How this service works
Detect AI-generated text: overall verdict with confidence, AI/human/AI-assisted fractions, and a segment-by-segment breakdown with per-segment humanizer flags. Price scales with length: $0.06 per 100 words, rounded up; minimum $0.06
Output
Returns an overall verdict (AI, human, or AI-assisted), a confidence score, fractions indicating how much of the text is AI-generated, human-written, or AI-assisted, and a segment-by-segment breakdown showing which parts of the text triggered the detection.
Example use cases
Student essay AI screening
“I need to check if this student essay was AI-generated — run it through AI detection using the standard tier and tell me the overall verdict, confidence, and which sections look most AI-like.”
Humanized AI content detection
“This blog post looks suspicious — it might be AI-written then run through a humanizer tool. Can you analyze it with the premium tier so we can catch any AI-assisted tricks?”
Content moderation pipeline check
“Before we publish this user submission, check what fraction of it is AI-generated versus human-written using standard detection and give me the breakdown.”
Technical details
Endpoint
POSThttps://glim.sh/api/v1/detect/aiWhen to prefer
Use this endpoint when you need to determine whether a piece of text was written by AI, a human, or a combination — especially when you need per-segment granularity or want to catch humanized/paraphrased AI output (premium tier). Prefer the premium tier when robustness to evasion or humanizer tools matters; use standard for routine, cost-effective screening at scale.
Side effects
- Text shorter than 50 characters returns an error or very low confidence verdict
- Text exceeding 40,000 chars (standard) or 20,000 chars (premium) is rejected
- Very short texts return lower-confidence verdicts due to insufficient signal
- Network or payment failure results in no response
- Invalid tier enum value returns a validation error
