What Physicians Need to Know

Voice Input
Perplexity AI supports voice input across its web, mobile, and desktop applications, enabling users to speak their queries instead of typing.
File Uploads (types & size limits)
Perplexity AI allows uploads of various file types including documents (PDF, DOCX, TXT, RTF, ODT, Markdown, JSON, HTML), spreadsheets (XLSX, CSV), presentations (PPTX), images (PNG, JPEG, HEF, WEBP, GIF), and audio/video (MP3, WAV, OGG, FLAC, AIFF, MP4, MOV, AVI, WEBM, MPEG, X-FLV, MPG, 3GPP). For free and Plus plans, the limit is 40 MB per file (up to 10 files per prompt). Pro users can upload files up to 50 MB, and Enterprise Pro accounts can handle up to 1 GB per file. Audio and video files up to 40 MB are automatically transcribed into searchable text.
Image Generation Capabilities
Perplexity AI can generate images directly from text prompts, excelling in creating illustrations, graphics, and concept art. It utilizes various models, including DALLu00b7E 3, FLUX.1, Nano Banana, and Seedream 4.5. Free users have limited daily generations, while Pro users have unlimited access. Images generated by free and individual Pro/Max plans are for personal, non-commercial use; commercial use is permitted for Enterprise Pro and Enterprise Max users.
Web Search (real-time or limited?)
Perplexity AI features real-time web search capabilities, providing up-to-date responses grounded in current internet content with cited sources. Its real-time search engine is known as Sonar.
Confabulation/Hallucination Risk Level
Perplexity AI is susceptible to hallucination, particularly when synthesizing information, compressing content, or addressing knowledge gaps. While its design emphasizes source citation to mitigate this risk and enhance transparency, it can still present AI-generated or outdated sources, leading to 'second-hand hallucinations.' One study indicated a 12.2% incorrect response rate, often due to misclassifications or minor fabrications. Users are advised to diligently verify sources.
Desktop & Mobile Apps
Perplexity AI offers native desktop applications for macOS and Windows, as well as mobile apps for iOS and Android devices. The mobile app is noted for its usability and comparable speed to the desktop version.
Third-Party Integrations
Perplexity provides an API for developers to integrate its search functionalities into custom applications and automated workflows. Integrations and connectors are available for tools such as Obsidian, Notion, Zapier, Make.com, Slack, Google Drive, and Canva (via Appy Pie Automate).
Prompt Engineering Tips
Effective prompting involves being specific and contextual, thinking like a web search user. Prioritize retrieval intent, scope, and evidence rules, starting with a clear deliverable (e.g., 'compare,' 'extract,' 'summarize'). Define scope boundaries (e.g., region, timeframe, audience). Separate retrieval constraints from stylistic instructions. For complex tasks, use iterative prompting across multiple turns. Introduce file uploads early in document-centric workflows. Avoid overly generic or complex multi-part questions. Do not ask for URLs or source links directly in prompts, as they may be hallucinated. Consider breaking down complex requests into smaller, specific queries for verification. Giving the AI a 'profile' (e.g., 'act as a research collaborator') and being detailed in instructions can improve results. Also, instruct the AI to ask for clarification in ambiguous scenarios.
Data Privacy for Physicians
For Perplexity Health, data is protected with encryption in transit and at rest, strict access controls, and user tools for data management and deletion. Health data, including chats, connector data, files, and memories, is explicitly *not* used to train AI models and is *never* sold to third parties. Perplexity is SOC 2 Type II certified and GDPR compliant. Perplexity Enterprise Pro and Enterprise Max can achieve HIPAA compliance with a signed Business Associate Agreement (BAA). The Medical Records connection for Perplexity Health is powered by b.well, a HIPAA-compliant platform.
Physician Tip

For non-clinical tasks, leverage Perplexity AI's real-time search and citation features for quick, evidence-backed information. Always critically evaluate the cited sources, especially when dealing with rapidly evolving topics or if a single, unfamiliar source is provided, due to the inherent hallucination risk in LLMs. Utilize file upload capabilities for summarizing research papers or internal documents. For sensitive health information, ensure your organization has a signed Business Associate Agreement (BAA) with Perplexity for Enterprise Pro or Enterprise Max plans, as the consumer versions are not HIPAA compliant. Use specific and detailed prompts to guide the AI's search and synthesis, treating it as a research assistant rather than a definitive authority.

While Perplexity AI offers an API for custom integrations, direct out-of-the-box integrations with common enterprise tools like Canva, Zapier, and Slack are primarily achieved through third-party automation platforms (e.g., Appy Pie Automate, Zapier, Make.com) or unofficial plugins. This means some technical setup or reliance on these intermediary services may be required to connect Perplexity with your existing non-clinical workflows.
