PEC Plus

Clinical guidance inside Brazil's PEC E-SUS primary-care record

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.

Strengths & Pros

+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

Perplexity

Real-time AI answer engine and research workspace combining live web citations with frontier reasoning models.

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.

Strengths & Pros

+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.
