Perplexity
A free AI-powered answer engine that provides accurate, trusted, and real-time answers to any question.
Location: USA ⓘ San Francisco, California
Perplexity Max: Includes Pro features plus the highest access to advanced AI models, expanded limits for “Create files and apps,” early access to new products, and prioritized support.
Education Pro: For verified students and educators; includes Pro features plus more citations, file and image uploads, Study Mode, expanded access to Perplexity Research and Perplexity Academic.
Enterprise Pro: Includes Pro features plus strict privacy features, no use of data for training, seat/user management, organizational file storage, internal knowledge search, increased file uploads, admin controls, team spaces, and dedicated support.
Enterprise Max: Includes Enterprise Pro features plus higher limits for Research, file and app creation, video generation, advanced models, larger file repositories, SCIM, audit logs, configurable data retention, and an insights dashboard. Other Sonar API: Separate pay-as-you-go model for developers and businesses that want to integrate Perplexity features into their own products, workflows, or automations. API usage is managed separately via credits or auto top-up; a Perplexity subscription is not required for API access. The API does not offer Pro/Max features within the web app and, according to Perplexity, does not log or store data.
Important: API access is not automatically included in Enterprise plans; Enterprise and API are treated separately.
Target audience
Perplexity is aimed at several clearly distinguishable target groups: first, private users and knowledge workers who want a faster, citable alternative to traditional web search; second, freelancers, analysts, consultants, and editorial teams who create more complex research, comparisons, and reports; third, organizations that want to combine internal knowledge from files and connected tools with web sources; fourth, developers who want to integrate Perplexity search or Sonar models into their own products. Education Pro and Learn Mode also show that education and academic use have now become an official focus.
Outstanding features
The strongest differentiating features are the combination of up-to-date web search, answers with sources, Deep Research, Internal Knowledge Search, and asset creation. Unlike pure chat tools, Perplexity combines research with operational follow-up processing: documents, presentations, spreadsheets, or small apps can be generated from a research thread. For teams, there are also org repositories, connectors, admin controls, retention settings, and auditing; for developers, Search API, Agent API, and Sonar API.
Main areas of application
Perplexity is strongest wherever current, verifiable information needs to be quickly turned into usable results: market and competitive research, academic research, due diligence, internal knowledge search, report creation, presentation preparation, source collection, file/document analysis, and research-oriented knowledge work. In the enterprise sector, the focus also shifts further toward an internal knowledge hub, team collaboration, connector-based search, and governance. Via the API, Perplexity is also suitable for search, research, and agent functions in proprietary applications.
Usage & notes
For simple questions, Free is often sufficient; for reliable work use, Pro is the more realistic starting point. Anyone working with confidential data, internal documents, or team knowledge should not equate the consumer plans with Enterprise: with Free/Pro/Max, AI data usage is generally opt-out by default, whereas Enterprise explicitly offers “never used for training” and more controls. It is also important to check pricing carefully, because Perplexity now combines several product lines: Consumer Search, Research, Create, Comet/Computer, Enterprise, and API. This is precisely what makes the platform powerful, but also less lightweight than a pure search engine.
| Who is it suitable for? | Assessment & rationale |
|---|---|
| Private individuals | Suitable – Perplexity offers a Free/Standard plan with many basic searches and limited Pro searches; useful for quick everyday research, learning, topic overviews, and finding sources. For intensive use, Pro or Max are more suitable because they include advanced models, more file uploads, as well as image and video generation. |
| Self-employed / freelancers | Very suitable – especially for research, content ideas, market and competitive analysis, SEO preparation, client briefings, and quick summaries. This aligns strongly with the use cases Research, Texts / Content, SEO / GEO, Marketing / Advertising, and Knowledge management / internal search. |
| SMEs / small teams | Suitable to very suitable – Perplexity Enterprise is designed for teams that want to use web research, internal files, and tools on one platform; according to Perplexity, teams can retrieve answers from files, integrations, and web sources. |
| Large enterprises | Very suitable – according to Perplexity, Enterprise Pro is aimed at organizations that want to increase productivity, answer complex questions faster, and meet stricter security requirements; it offers, among other things, user management, higher data protection standards, and SOC 2 alignment. |
| Developers / technical teams | Very suitable – the Perplexity API can be used for Search, Sonar, Agent API, and embeddings; suitable for AI search, RAG, Q&A applications, research tools, AI assistants, and apps with current web sources. |
| Privacy-conscious companies | Conditionally to well suited – positive: Perplexity states that it does not use Enterprise data for training or fine-tuning; according to the Help Center, uploaded files are deleted after seven days. Important: with Free, Pro, and Max, “AI Data Retention” is enabled by default and must be actively disabled if data is not to be used for training. |
| Pure creative/image users | Conditionally suitable – according to Perplexity, Pro offers image and video generation, but Perplexity’s core strength clearly lies in search, research, source work, and knowledge questions, not primarily in creative production. |
| Users who only need chat without sources | Conditionally suitable – Perplexity can be used in a chat-like way, but it is particularly strong when current information, sources, web research, and verifiable answers matter. For pure writing assistance without research, ChatGPT, Claude, or Gemini may be more suitable depending on the workflow. |
Hosting & Data
1) On-prem / local hosting
Meaning: The company operates the solution on its own hardware or within its own infrastructure. In the strictest sense, not only the application runs locally, but ideally the model as well.
2) Private cloud / data center
Meaning: The solution runs in a dedicated or more clearly separated cloud environment, often with a hosting provider or hyperscaler, but in a German data center or in a particularly controlled environment.
3) EU SaaS / managed
Meaning: The provider operates the solution itself as a service. The company uses the tool as a ready-made cloud service, ideally with EU data residency.
4) Hybrid
Meaning: One part of the processing remains internal / local / in a private cloud, while another part runs in an external cloud or EU SaaS.
5) AVV / DPA
Meaning: This is the data processing agreement or Data Processing Addendum. It governs that the provider processes personal data on behalf of the customer and is bound by the customer's instructions.
6) No training
Meaning: The provider does not use your prompts, uploads, attachments, chat histories, or outputs for training or improving the general model — ideally excluded by contract.
7) Open-source / transparency path
Meaning: There is a path toward greater technical transparency and sovereignty, for example through:
- open models
- documented components
- self-hostable parts
- traceable architecture
- export / switching options

For GDPR-sensitive companies, Perplexity Enterprise or the Sonar API is significantly more suitable than Free/Pro/Max. Enterprise/API offer a DPA, no-training commitments, and stronger security/retention controls. Critical concerns remain US/North America hosting, global subprocessors/model providers, and the lack of documented EU-only data residency.
Conclusion:
Perplexity is conditionally suitable for GDPR-relevant enterprise use, most likely via Enterprise Pro / Enterprise Max or the Sonar API with a DPA/data processing agreement, no-training commitment, and clear internal usage policies. For sensitive personal data, professional secrets, health data, or strictly regulated content, Perplexity is not recommended without an Enterprise/API setup and a data protection review.

GDPR-compliant usage possible?
Perplexity must be assessed based on the usage context: Free / Pro / Max, Enterprise Pro / Enterprise Max, and Perplexity API / Sonar API differ significantly. Consumer use: According to the privacy policy, Perplexity AI, Inc. is the data controller for standard services; the privacy policy explicitly does not apply to Perplexity API or Enterprise Pro, where Perplexity acts as a data processor. Perplexity processes, among other things, account, payment, usage, prompt/output, device, location, and tracking data; service interaction information may contain personal data. Free / Pro / Max: According to the Help Center, AI Data Retention is enabled by default; users can opt out via a toggle, but opt-outs apply only to data collected in the future, and according to Perplexity, training data that has already been used cannot be deleted. Enterprise: significantly better suited: according to Perplexity, Enterprise data is not used for training or fine-tuning; according to Perplexity, third-party AI providers such as OpenAI and Anthropic are contractually bound so that Perplexity data is not used for model training. Uploaded files are deleted by default after seven days in Enterprise; larger Enterprise configurations include additional retention controls. API / Sonar API: Perplexity states a strict zero-data-retention policy: content sent to the Sonar API is not stored and is not used for model training; only billing/operational metadata such as token count, model, timestamp, duration, and API key identifier are stored, without prompt or response content. DPA / Data Processing Agreement: Yes, for business/enterprise/API contexts. The Perplexity DPA is incorporated into the Enterprise and API terms; in it, the customer is the controller or processor and Perplexity is the processor or service provider. The DPA includes EU/UK data protection references, SCCs, subprocessor provisions, data subject rights, data breach notification, audit/documentation obligations, and deletion within 30 days after the end of service provision.
Positive: DPA/Data Processing Agreement available, SCCs, EU-U.S. Data Privacy Framework, SOC 2 Type II, Enterprise no-training, API zero data retention, Enterprise file retention, and admin controls.
Negative / Points to review: U.S. provider, servers according to the privacy policy in the U.S., API compute according to the FAQ via AWS in North America, subprocessors and model providers according to the DPA worldwide, no confirmed EU-only data residency found. For Free/Pro/Max, Perplexity is only of limited suitability for personal, confidential, or sensitive data because AI Data Retention is enabled by default.
