## CasperPractice

CasperPractice is a specialist study platform for the CASPer situational judgment test, the open-response admissions assessment created at McMaster University and used by hundreds of health-science programs. Instead of generic chatbot feedback, the product runs a dedicated scoring model trained on a large corpus of real candidate answers, so responses are graded against the scale evaluators actually use and placed in a quartile band.

The workflow mirrors test day closely. You open a scenario, watch or read it once, and the timer starts; you then type or record a video answer exactly as you would in a live sitting. Within seconds you receive a quartile ranking, notes on specific sentences, and a rewritten version of your answer that demonstrates the reasoning a top-quartile response would show. A practice-test mode groups scenarios into full-length simulations so you can rehearse stamina and pacing, not just individual questions.

The library is broad — every major scenario type is represented, including ethics, empathy, collaboration, resilience, personal experience and media-based prompts. Progress accumulates across attempts, which makes it easy to spot recurring weaknesses such as one-sided arguments or unsupported claims. Free users can try the questions with limited AI coaching, while the paid Pro plan unlocks unlimited scoring and the 4th quartile guarantee, subject to stated conditions like answering a minimum number of questions with the same email used for the real test.

**Pricing & Plans:** Freemium. A free tier gives access to practice questions with limited AI coaching (the first attempts are coached at no cost), while the Pro plan is a paid subscription that unlocks unlimited scored attempts and the 4th quartile money-back guarantee. Pricing is discounted periodically on the site.

- **Realistic question bank and full mock tests:** Work through hundreds of typed, video and media-based scenarios, or take complete simulations that reproduce the CASPer sections, question order and per-question time limits.
- **Purpose-built AI scorer:** Answers are graded by a model calibrated on a large set of real CASPer responses, returning a quartile estimate rather than vague encouragement, plus sentence-level notes on what weakened the answer.
- **Instant answer rewrite:** After each attempt you get a stronger version of your own response, showing how to hold competing perspectives and land on a clear position without sounding rehearsed.
- **Competency coverage tracking:** Attempts are mapped to the competencies CASPer measures, so you can see whether ethics, communication or collaboration is dragging your average down and drill the weakest one.
- **4th quartile guarantee on Pro:** Pro subscribers who meet the conditions (minimum answered questions, matching email, official results forwarded in time) are refunded or keep lifetime access if they miss the top quartile.

**Strengths:** Purpose-built scoring model rather than a generic chatbot prompt; Quartile ranking and rewrites give concrete, comparable feedback; Full-length simulations mirror the real sections and time limits; Bonus: large free question set and a money-back guarantee on the paid plan

**Limitations:** Value depends on the accuracy of third-party AI scores, which only the official provider can truly validate; The free tier's coaching is limited, so meaningful practice volume requires a paid plan; Video-response practice still cannot replicate the pressure of a live proctored sitting

## 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.
