## PEC Plus

PEC Plus is a lightweight Chrome extension built for health professionals who use PEC, the electronic health record of Brazil's E-SUS Atenção Básica (primary health care) system. Rather than replacing the record, it plugs into it: as a doctor or nurse works through a consultation, the extension reads what has been selected in the SOAP "Avaliação" (assessment) field and surfaces timely, context-specific guidance right where the decision is being made.

The extension focuses on a few high-value moments. For compulsory-notification diseases and conditions, selecting a diagnosis triggers a reminder to complete the SINAN form, with links to download the form and to the Ministry of Health's official list of notifiable conditions under Portaria GM/MS No. 217. For longitudinal monitoring, it suggests validated scores tied to the selected problem — GAD-7 for anxiety-related issues, PHQ-9 for depressive disorders and a Mini-Mental State Examination form for dementia syndromes. And in the "Planos" field, requesting MRPA or a glycemic diary/map produces a printable PDF template.

The tool is published on the Chrome Web Store by developer Heric Santos, is offered free of charge, and runs only in Brazilian Portuguese. It has a small user base so far. Importantly, it is an assistive aid, not an autonomous diagnosis system, and in line with LGPD it neither saves nor transmits patient information, keeping data handling on the clinician's own session.

**Pricing & Plans:** Free. PEC Plus is a free Chrome extension with no published paid tiers.

- **SINAN notification reminders:** When you select a notifiable disease in the SOAP assessment field, PEC Plus prompts you to complete the SINAN form and links to the form and the Ministry of Health's official list.
- **Score suggestions:** It suggests validated instruments matched to the problem, such as GAD-7 for anxiety, PHQ-9 for depression and the Mini-Mental State Examination for dementia syndromes.
- **MRPA and glycemic diary templates:** Requesting MRPA or a glycemic diary in the 'Planos' field produces a ready-to-print PDF template.
- **In-workflow guidance:** Guidance appears directly inside the PEC during the consultation, so it fits the existing SOAP workflow instead of replacing it.
- **LGPD-compliant by design:** The extension does not save or transmit patient information, aligning with Brazil's LGPD data-protection law.

**Strengths:** Sits inside the existing PEC E-SUS workflow rather than replacing it; Surfaces SINAN notification reminders at the right moment; Suggests validated scores like GAD-7, PHQ-9 and MMSE; Generates printable MRPA and glycemic diary templates

**Limitations:** Portuguese-only and no ratings yet on the Chrome Web Store; Requires existing access to the PEC E-SUS AB system to be useful; Last updated in 2023, so it may lag behind PEC changes; Suggestion-based only; it is not a standalone diagnosis tool

## 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.
