Which tools are included?

Three: the AI Detector, Journal Finder and AI Humanizer. On the Free plan, all three share one daily run limit. On Limited and Pro, each tool you add has its own separate daily run limit (or daily word budget for the Humanizer).

What can the AI Detector analyze?

Paste any text of at least 20 words, or upload a PDF or DOCX up to 20 MB — including files already stored in your account. Long documents run as background jobs through a four-stage pipeline, and you can navigate away while a header pill tracks progress.

How are detection results explained?

Every sentence gets its own AI probability, color-banded by confidence (red ≥99%, orange ≥96%, yellow ≥93%), plus a sub-classification of raw AI-generated versus AI-paraphrased writing. You also get an overall stylometry gauge, a similarity index with DOI-linked sources, and a downloadable highlighted PDF report.

How does Journal Finder rank journals?

It searches 9 academic databases in parallel and ranks results with a hybrid score: 50% semantic similarity to your abstract, 30% domain alignment and 20% multi-source agreement. Each result is enriched with Scimago metadata — SJR, H-index and quartile (Q1–Q4) — plus open-access flags and matching articles.

How does storage work?

Every plan includes storage for files you upload to the file manager and reuse across AI tools — 50 MB on Free and Pay-per-Run, 2 GB on Limited, 20 GB on Pro. Storage is personal to your account, with no sharing or pooling.

Yes. Everything is scoped to your account — files, run history and results are yours alone, and access is checked on the API itself for every request. Nobody else can see your documents.

What happens when I hit my daily limit?

You can wait for the next day (limits reset daily), upgrade to Limited or Pro for a higher cap, or — for the AI Detector or Journal Finder only — buy a single Pay-per-Run unlock to keep going right away. Pay-per-Run isn't available for the Humanizer.

Q: How does pricing work?

There are no credits. Every account starts on the Free plan (1 AI run a day, shared across all three tools). Limited and Pro let you add only the services you want — each one has its own daily limit and its own monthly or yearly price. Pay-per-Run unlocks a single run of the AI Detector or Journal Finder for a flat per-service fee any time, no subscription required.

Five simple tools for academic work: detect AI-written text, check it against academic sources, find the right journal, rewrite your draft, and more. Free to start.

Three AI tools for academic work

From sentence-level AI detection to finding the right journal — every stage of the academic workflow, in one place.

AI Detector

Paste text or upload a PDF/DOCX up to 20 MB. A four-stage pipeline extracts, detects, cross-checks similarity and maps every sentence with its own AI probability.

How the AI Detector works

Instead of one overall score, the AI Detector checks each sentence on its own and shows the sources it compared against — so you can see exactly why a document was flagged.

01 / 04

step 01

Sentence-level evidence

Every sentence carries its own AI probability, color-banded by confidence. Click one and the neural metrics open — including whether it reads as raw AI output or AI-paraphrased human writing.

How your account works

No workspace to set up — sign in, pick a plan, and every AI tool is ready with a daily run limit, word limit and storage cap that scale as you upgrade.

Plan usage, always visible

Your daily run count updates live as you work, per service. Cross the limit and you can upgrade, or — for the AI Detector and Journal Finder — buy a single Pay-per-Run unlock instead of a hard stop mid-deadline.

What this platform does

The AI Detector checks a document sentence by sentence and shows exactly why it flagged each one — not just a single score.

Journal Finder and AI Humanizer cover the rest of the writing process. Every account starts on a free plan, with paid plans for higher daily limits.

01
Evidence first
Per-sentence probabilities, DOI-linked sources and downloadable reports — never a black-box verdict.
02
Server-enforced limits
Daily run caps, per-run word limits and storage quotas are checked on the API itself, not just hidden in the interface.
03
Transparent pricing
Every service has a clear, listed price and daily limit — subscribe monthly or yearly on Limited/Pro, or pay per run with no subscription. No metered or per-word fees to track.
