## CT Read

CT Read is a web platform that uses AI to help people understand medical imaging. Rather than reading raw radiology output, users upload their scans and receive a structured report written in accessible language, covering key findings, likely areas of concern and suggested next steps. The service targets non-medical users such as patients and their families, while also offering a summary-first workflow that clinicians can use as a starting point.

The tool supports multiple imaging modalities — X-ray, CT, MRI, PET and ultrasound — and can analyse many body regions including brain, chest, abdomen and bones. Uploads accept DICOM files as well as JPG, JPEG and PNG images, so users can work with whatever their imaging centre provided. Alongside the analysis engine, CT Read runs a set of free DICOM utilities: an online DICOM viewer, a DICOM-to-JPG converter, a DICOM-to-PDF converter and a DICOM anonymiser.

The interface is translated into many languages including English, German, French, Spanish, Portuguese, Dutch, Turkish, Indonesian, Japanese, Korean, Traditional Chinese and Arabic, and the site runs on a credit-based model. CT Read clearly positions itself as an aid for understanding images rather than a replacement for professional diagnosis.

**Pricing & Plans:** Paid, credit-based. The site uses a credit balance for analyses and offers a free first analysis; specific credit bundles and prices are listed on the Pricing page.

- **Multi-modality analysis:** Interpret X-rays, CT scans, MRI, PET and ultrasound images with a single tool rather than separate services.
- **DICOM and image format support:** Upload DICOM files directly or use common formats such as JPG, JPEG and PNG.
- **Plain-language reports:** Receive structured findings, recommendations and an easy-to-understand summary instead of raw radiology jargon.
- **Free DICOM utilities:** Use the built-in online DICOM viewer, DICOM-to-JPG converter, DICOM-to-PDF converter and DICOM anonymiser at no cost.
- **Full-body coverage:** Analyse scans from the brain, chest, abdomen, bones and other regions for a broad health overview.

**Strengths:** Handles DICOM plus everyday image formats in one place; Reports are written for non-medical readers; Includes free DICOM tools such as a viewer and anonymiser; Interface available in many languages

**Limitations:** Not a substitute for a qualified medical professional's diagnosis; Credit-based pricing requires purchases for ongoing use; AI interpretation of medical images can never guarantee full accuracy

## 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.
