Perplexity answers questions with a short answer and numbered links to sources, so it fits wherever you need fresh facts: checking a counterparty, reviewing competitor prices, industry news, changes in legislation. Deep Research mode compiles a report across dozens of sources in a few minutes, and Pro mode lets you choose the model (OpenAI, Anthropic, Google, its own Sonar). It handles questions in many languages. There are phone and desktop apps and the Comet browser.

Pitfalls to watch at work
- The links are there, but the model sometimes retells what is behind them inaccurately: open the source and find the claim word for word
- For official registers (company, court, tax) the engine gives only a surface picture: check critical facts in the register itself
- On the free plan, turn off AI Data Retention in settings, otherwise queries with client names may be used for training
Billing
Card payment through Stripe, or through the App Store and Google Play. Whether VAT or sales tax appears depends on your country and payment channel: app stores always add local tax.
