AskYourPDF – Research Assistant GPT
AskYourPDF Research Assistant GPT is a specialised document-analysis model built to handle long PDFs, academic papers, lecture notes, reports, and textbooks. Instead of giving broad answers, it reads the file you upload, understands its structure, and responds using the exact content from that document. This makes it reliable for studying, research, and assignments that depend on accuracy. It can summarise sections, explain difficult paragraphs, extract citations, and help you understand key ideas without manually combing through dozens of pages.
Features
- Accurate, document-based responses: All answers come directly from the uploaded file. No guessing. No invented information. Whatever it explains or summarises is tied to the source you provided.
- Handles long and complex PDFs: It works well with large textbooks, journal articles, multi-chapter reports, and scanned academic materials. It maintains context across sections, which is useful when you’re dealing with technical or layered writing.
- Smart summaries and explanations: You can request chapter summaries, topic breakdowns, definitions, or simplified explanations of dense sections. It delivers the kind of clarity that helps during revision or when you need a quick understanding before class.
- Citation extraction: It can pull out quotes, page numbers, references, and bibliographic information. This is especially helpful for research papers where you need multiple sources.
- Multi-file support: Beyond PDFs, it works with slides, research notes, and other text-based academic materials. This helps keep all your readings in one place.
- Study assistance: It can help organise reading notes, highlight key arguments, and show the main ideas throughout the file. It’s useful for preparing essays or presentations based on long documents.
Pricing
AskYourPDF uses a tiered plan system with clear limits for pages, documents, and daily usage:
- Free Plan – $0/month
- Premium Plan – $11.99/month (billed annually)
- Pro Plan – $14.99/month (billed annually)
- Enterprise – Custom Pricing
ChatGPT 5.1
ChatGPT 5.1 is an all-purpose GPT model built to help students with day-to-day academic work. It’s strong at breaking down complex topics, explaining concepts in simple language, and helping you organise your thoughts when writing essays or preparing assignments. The model understands context well, so it can help you structure arguments, clean up messy paragraphs, or turn rough ideas into something usable. Unlike tools that focus on a specific function (like PDFs or research), ChatGPT 5.1 works across writing, studying, revision, brainstorming, and problem-solving.
Features
- Strong explanation and learning support: If you’re stuck on a topic—maybe an economics model, a biological process, or a literature theme—you can ask for a clearer breakdown.
- Flexible writing assistance: It helps tidy up essays, structure ideas, and improve clarity. You can feed it drafts, outlines, or half-formed thoughts, and it helps turn them into something coherent.
- Reasoning and problem-solving: ChatGPT 5.1 is strong at step-by-step explanations in subjects like math, physics, economics, and logic-based courses. It won’t replace studying, but it makes tough steps easier to follow.
- Idea generation and planning: If you need project ideas, research angles, or study plans, it generates options you can refine. It’s great for removing that “blank page” moment when you don’t know where to begin.
- Reading support with copy-paste: Even though it doesn’t specialise in PDFs, you can paste long paragraphs, cases, articles, or sections of notes, and it will summarise or clarify them accurately.
- Writing improvement: It can help adjust tone, simplify language, tighten sentences, or correct grammar.
Pricing
ChatGPT uses a simple subscription model through OpenAI:
- Free Plan – $0/month
- ChatGPT Plus (5.1 Access) – $20/month
- Team and Enterprise Plans – Custom pricing
For most students, the Plus plan is the best value because it unlocks the full reasoning and writing strength of GPT-5.1 while keeping everything simple and accessible.

Claude 3.5 Sonnet is one of the most balanced AI models for students who want smart, calm, and accurate help across academic tasks. It’s known for its strong reasoning, straightforward writing style, and ability to handle long, complex inputs without getting confused.

Features
- Strong analytical writing: Claude is excellent at breaking down a topic and presenting a well-structured answer.
- Great reading comprehension: It digests long reading materials easily. You can paste large paragraphs from your textbook, lecture notes, PDFs, or research papers, and it will summarise, contrast ideas, pull out themes, or highlight arguments.
- Reasoning and problem support: Claude performs well in subjects that require step-by-step thinking: mathematics, economics, physics, logic, and philosophy.
- Code and STEM support: Although it’s not a specialised coding model, it’s very good at clarifying code snippets, debugging logic, and explaining concepts behind algorithms.
- Long-context memory handling: Claude 3.5 Sonnet can maintain coherence across longer conversations and large text inputs.
- Clean, human-like tone: Claude has a natural, polished writing voice that students appreciate when working on essays, reports, or assignments.

Perplexity AI
Perplexity AI is a research-driven assistant that pulls accurate, real-time information from the web and breaks it down into clear answers. Instead of relying only on pre-trained data, it searches trusted sources, compares viewpoints, and presents results with citations you can verify. This makes it especially useful for students who want reliable information quickly, whether they’re researching an essay, preparing a presentation, or studying a new topic. The tool works like a mix of a search engine and an AI explainer—giving you the depth of Google results with the clarity of a well-written summary.
Features
- Real-time web search: Perplexity fetches up-to-date information by scanning the web when you ask a question. This ensures answers reflect the latest data, news, research updates, or academic discussions.
- Citation-backed responses: Every answer includes a list of sources at the bottom—blogs, journals, research papers, news articles, or educational sites.
- Copilot mode: Copilot is a guided research assistant. Instead of giving a single answer, it digs through multiple sources, compares them, and presents a structured explanation.
- Contextual understanding of follow-up questions: You can ask deeper questions after the first response, and Perplexity continues the thread without losing context.
- File uploads: With Perplexity Pro, students can upload documents and ask the tool to summarise, explain, or extract details.
- Simple, clean interface: The layout emphasises clarity. Answers appear first. Sources appear directly below.
Pricing
Perplexity keeps its pricing simple:
- Free Plan – $0/month
- Pro Plan – $20/month or $200/year
For most students, the free plan works well for regular study tasks.
