## 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

## Semantic Scholar

Semantic Scholar was launched by the Allen Institute for AI as an attempt to solve a very specific problem: scientific output grows far faster than any individual researcher's ability to read it. Instead of matching literal keywords, the platform applies natural-language processing and graph analysis to figure out what a paper is actually about, who it builds on, and which citations inside it mattered — surfacing papers a keyword search would never rank highly.

The catalog spans more than 240 million publications from journals, conference proceedings, preprint servers and repositories, with records combining metadata, abstracts, references, citation counts and extracted entities such as methods, datasets and figures. On top of the core search experience sit features like one-sentence AI TLDRs, Semantic Reader (an augmented PDF reader that surfaces inline citations, definitions and figures while you read), author and venue pages, research feeds, and a Scholar's Hub for tracking the people and topics you care about.

Everything on the site is free to use, and a developer API gives researchers, students and engineers programmatic access to the same corpus — the API now supports paper search, better documentation and improved stability. Because it is a non-profit academic project rather than a commercial product, there is no paid tier: the value proposition is depth of coverage and semantic relevance, not premium features.

**Pricing & Plans:** Completely free. Semantic Scholar is operated as a non-profit academic project by the Allen Institute for AI, with no subscription tiers — accounts, search, Semantic Reader and the developer API are all available at no cost.

- **Semantic search across 240M+ papers:** Search 241 million-plus publications from every scientific field using natural-language queries that match meaning rather than exact keywords.
- **AI-generated TLDR summaries:** Each indexed paper gets a one-sentence machine-generated TLDR so you can triage results before committing to reading the full text.
- **Semantic Reader:** An augmented PDF reader that highlights citations, definitions, equations and figures inline, and shows which later papers cited the passage you are reading.
- **Citation context and influence signals:** See how a paper was cited, whether citations were influential, and which references shaped the work — useful for literature reviews and citation chasing.
- **Free developer API and Scholar's Hub:** A documented public API exposes search and metadata endpoints at no charge, while Scholar's Hub lets you follow authors, topics and citation alerts.

**Strengths:** Free to use with no paywall, subscription or credit limits; Very broad coverage spanning 240M+ papers in all scientific fields; Semantic ranking and AI TLDRs surface relevant work that keyword search misses; Semantic Reader adds inline citations, definitions and figures during reading

**Limitations:** Indexing lag means the newest preprints are not always immediately available; TLDR summaries are machine-generated and can oversimplify nuanced findings; Full text is frequently limited to what publishers or repositories expose; Not a citation manager: no built-in PDF library, BibTeX export workflow or note system
