## OETStudy

OETStudy is an independent study platform built around the Duolingo English Test, an online proficiency exam many universities accept. Its central promise is exam-style practice combined with automated feedback: learners work through sections covering speaking, writing, listening, and reading, then receive AI-generated scoring and suggestions aimed at pushing them toward a higher band.

The content side is substantial. The platform advertises more than 15,000 practice questions organised by question type and difficulty, so you can drill specific task formats rather than only taking full mock tests. Around that core sit study tools: CEFR-based vocabulary assessment, personal word lists clustered from your practice data, performance statistics, and score analysis that flags weak areas. There is also a community element, with a study group of active users for shared preparation.

The pricing model is generous for a test-prep resource, offering free practice questions and basic features, with premium AI scoring and deeper analytics available for full preparation. One thing to note: OETStudy states plainly that it is not endorsed by or affiliated with Duolingo, so it should be treated as third-party preparation support rather than an official source of DET scores.

**Pricing & Plans:** OETStudy offers free practice questions and basic features, with premium features covering comprehensive preparation such as AI scoring and detailed analytics. No credit card is required to start.

- **15,000+ practice questions:** A large bank of DET-style items spanning speaking, writing, listening, and reading, graded by difficulty so you can practise at the level you need.
- **AI speaking and writing scoring:** Speaking and writing submissions are scored automatically, evaluating pronunciation, fluency, grammar, and content structure with suggestions for improvement.
- **CEFR vocabulary tools:** Check your vocabulary level against CEFR bands and build word lists clustered around the question types you practise most.
- **Progress analytics:** Practice statistics and score analysis highlight weak areas and show how your performance changes over time.
- **Targeted question drills:** Focus practice on the specific DET task types where you need the most improvement rather than working through everything equally.

**Strengths:** Large, DET-aligned question bank across all four sections; AI scoring provides instant speaking and writing feedback; CEFR and vocabulary tools support longer-term language growth; Free tier lets you practise before paying for premium features

**Limitations:** Some content and features are JS-dependent and may not render on older browsers; Premium scoring and analytics sit behind the free practice tier; AI scoring is a practice aid and not the official DET result

## Perplexity

Perplexity is an AI-native answer engine and autonomous research platform designed to replace traditional keyword search and fragmented browser tab workflows. Instead of returning a ranked list of blue links, Perplexity interprets complex natural-language queries, crawls live web indexes, academic databases, financial filings, and social discussions in real time, and synthesizes direct, structured answers anchored by numbered inline citations. Beyond conversational search, the platform has evolved into a broader agentic ecosystem encompassing Perplexity Computer for autonomous multi-step tasks and the Comet AI browser assistant.

Under the hood, Perplexity orchestrates its proprietary web-grounded Sonar model family alongside frontier third-party reasoning models—allowing paid subscribers to route queries through Claude Opus 4 and Sonnet 4, OpenAI's o3-pro and GPT series, or Google's Gemini models, or run parallel evaluations via Model Council. Its Deep Research mode autonomously decomposes intricate questions, conducts dozens of iterative searches across hundreds of primary sources, and compiles exhaustive, exportable briefing reports in minutes. Users can also organize ongoing projects inside Perplexity Spaces, which fuse uploaded private documents (PDFs, CSVs, docs) with live web grounding and custom system instructions.

Perplexity serves an expansive audience ranging from students and journalists to equity analysts, legal researchers, and software engineers. Individual users can rely on the free tier for everyday fact-checking, step up to Perplexity Pro ($20/month) for daily deep research and model switching, or subscribe to Perplexity Max ($200/month) for uncapped high-compute agentic runs. Organizations adopt Enterprise Pro ($40/seat/month) and Enterprise Max ($325/seat/month) for SOC 2 compliance, zero data training guarantees, and internal knowledge connectors, while developers integrate real-time grounded citations into custom software via the Sonar REST API.

**Pricing & Plans:** Offers a permanent Free tier with unlimited Quick Searches, 3 Pro Searches per day, and 1 Deep Research query per month; Perplexity Pro costs $20/month ($200/year) and Perplexity Max costs $200/month ($2,000/year) for individuals. Team plans start at $40/seat/month ($400/seat/year) for Enterprise Pro and $325/seat/month for Enterprise Max, alongside usage-based Sonar API billing.

- **Deep Research Autonomous Reports:** Executes multi-step iterative web and document research across hundreds of sources, cross-checking facts and generating structured, citation-backed analytical reports that can be exported as PDFs or shared as interactive Perplexity Pages.
- **Multi-Model Routing & Model Council:** Lets Pro and Max subscribers switch dynamically between Perplexity's in-house Sonar models and top external models (including Claude 4, o3-pro, and Gemini) or compare multi-model reasoning outputs side by side.
- **Perplexity Spaces & Hybrid RAG:** Provides dedicated project workspaces where users upload local PDFs, spreadsheets, and text files, configure custom assistant instructions, and run queries that combine private document retrieval with live internet search.
- **Perplexity Computer & Comet Assistant:** Extends Perplexity from passive Q&A into agentic execution, turning high-level user requests into completed workflows, multi-tab browser actions, and automated data synthesis via the Comet ecosystem.
- **Sonar Web-Grounded Developer API:** Exposes Sonar, Sonar Pro, Sonar Reasoning Pro, and Sonar Deep Research over standard HTTP endpoints so developers can embed low-latency, live-cited web intelligence directly into third-party applications.

**Strengths:** Every generated statement links directly to numbered, verifiable web or document sources, drastically reducing ungrounded LLM hallucinations.; Deep Research mode delivers comprehensive, multi-page synthesis reports at a fraction of the time required for manual desk research.; Broad model optionality lets subscribers use Sonar, Claude, OpenAI, and Gemini models under a single $20/month subscription.; Focused search scopes (Academic, Finance, Web, Social) and Spaces allow clean separation between general browsing and domain-specific knowledge work.

**Limitations:** The Free tier is tightly restricted to 3 Pro Searches per day and just 1 Deep Research query per month with no manual model selection.; Power users requiring heavy agentic Computer runs or uncapped o3-pro/Opus-level research must jump from $20/month Pro to the steep $200/month Max tier.; Synthesized summaries can still inherit inaccuracies if underlying top-ranked web sources contain outdated or biased reporting.
