## AskSia

AskSia centres on the idea that a study assistant should answer from your materials, not from the open internet. You upload lectures, PDFs, slides and readings, and the platform transcribes, highlights key concepts, organizes notes by course and answers questions about specific sections of your own sources. Content can be captured by recording a live lecture with speaker identification, by uploading audio or video, or by having the browser extension pull readings and slides straight from Canvas, Blackboard, Brightspace, Moodle, Echo360, Panopto and similar systems.

The product suite covers several study modes. The web app generates summaries, cheat sheets, flashcards and quizzes, solves problems step by step with visual explanations, and offers transcription plus translation in more than 30 languages. The mobile app adds camera-based question capture for quick explanations. Sia Agent, a standalone macOS and Windows application, runs a diagnostic, builds a day-by-day exam plan, teaches on a live whiteboard while it talks and estimates your score across 31 supported exams including SAT, AP, IB, A-Level, TOEFL and IELTS.

AskSia uses a freemium model with a no-card free plan and paid tiers that unlock unlimited uploads, full transcription and advanced note organization. Some paid plans advertise a Grade Confidence Guarantee tied to semester-long study and subscription requirements, with eligibility conditions and refund terms published in the guarantee policy. The company also positions the tool explicitly as a learning aid rather than a homework-copying service, asking students to respect their institution's academic integrity rules.

**Pricing & Plans:** Freemium. A free plan is available with no credit card required, covering basic study features. Paid plans unlock unlimited uploads, full lecture transcription and advanced note organization; promotional discounts are frequently advertised. The Grade Confidence Guarantee applies only to the eligible A+ plan and depends on meeting semester-long requirements.

- **Lecture transcription and smart tagging:** Record a live lecture or upload audio and video, then get a searchable transcript with key concepts, ideas and action items tagged automatically in real time.
- **Course-grounded question answering:** Ask questions against your own uploaded textbooks, slides and syllabus, so answers come from your course rather than generic internet results.
- **Auto-generated study assets:** Turn any material into summaries, cheat sheets, flashcards, quizzes and course maps, with step-by-step problem solving and visual explanations for STEM topics.
- **LMS browser extension:** Sync readings, slides and assignments from Canvas, Blackboard, Brightspace, Moodle, Echo360, Panopto and similar platforms in one click, read-only and roughly 30 seconds per course.
- **Sia Agent exam preparation:** A desktop agent that runs a diagnostic, builds a day-by-day plan for 31 supported exams, teaches on a live whiteboard and tracks an estimated score as you progress.

**Strengths:** Answers are grounded in your own uploaded materials, which is far more useful for coursework than a generic chatbot; Covers a wide study surface — transcription, notes, flashcards, quizzes, problem solving, translation and exam planning — in one account; Free plan with no credit card, plus a browser extension that syncs directly from most major LMS platforms; Desktop exam agent with diagnostics and predicted scores across 31 tests, a fairly unusual feature for a student tool

**Limitations:** The strongest features, including unlimited uploads and full transcription, sit behind paid plans; Grade Confidence Guarantee comes with strict semester-long eligibility conditions and is limited to the A+ plan; Because usage is tied to your own materials, it is only as good as what you upload, and it is not intended as a homework-completion service

## GPTZero

GPTZero grew out of the practical problem that teachers and editors faced once generative text became common: how do you tell whether a piece of writing came from a person or a model? The product answers that with a detector that returns an overall AI likelihood score and highlights individual sentences it considers machine-written, so a reader can see where the suspicion comes from rather than just receiving a single verdict.

Over time the platform widened from a single text box into a suite aimed at institutions. Detector results are paired with a plagiarism checker, grammar and writing feedback, and optional process verification such as a writing replay that records how a document was typed. A Chrome extension and Google Docs add-on push detection into the tools students and staff already use, and the company offers classroom integrations plus an API for bulk or programmatic checks.

Because the buyers are largely schools, districts, and universities, GPTZero leans heavily on privacy and compliance claims: it states SOC 2 Type II compliance and alignment with FERPA, GDPR, and CCPA, and says student writing is not used to train models. The practical takeaway is that it is positioned as an academic-integrity and editorial-review tool rather than a novelty checker, which also means its more powerful features sit in paid tiers.

**Pricing & Plans:** Freemium plus paid plans. A free tier provides core detection with character limits per scan, while paid individual and institutional plans unlock advanced scan modes, higher limits, writing reports, and classroom integrations. Enterprise and API access are quoted separately.

- **Sentence-level AI detection:** Paste text or upload a document and get an overall AI probability score plus a sentence-by-sentence breakdown of which parts look machine-written.
- **Multi-model coverage:** Flags AI text from major model families including ChatGPT, Gemini, Claude, Llama, and others, rather than training for a single model.
- **Browser and docs extensions:** A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.
- **Plagiarism checking:** Checks content for copied passages from outside sources so you can separate AI-generation questions from originality questions.
- **Writing process verification:** Writing replay and advanced reports offer evidence about how a document was produced, useful for academic integrity workflows.

**Strengths:** Sentence-level highlighting shows why a passage was flagged instead of only giving a score; Covers text from many different AI model families, not just one chatbot; Integrations with Chrome, Google Docs, Canvas, and Google Classroom fit existing school workflows; Publishes concrete compliance claims (SOC 2 Type II, FERPA, GDPR, CCPA) that institutions can review

**Limitations:** Detection is probabilistic and can flag polished human writing or miss lightly edited AI text; Free scans are capped by character count, and useful reporting features require payment; Lean heavily on a single score without human judgment can lead to unfair accusations
