Frequently asked questions
Why Perplexity instead of a plain LLM?
A plain LLM answers from stale training data and can hallucinate. Perplexity's Sonar models search the live web and return real citations, so your brief reflects what actually happened yesterday and every claim links to a source your team can verify. That difference is the whole point of using it for news.
How do I keep it focused on my niche?
The prompt is where you steer it. Instead of 'AI news', ask for 'the 5 most important developments in [your specific niche] in the last 24 hours, prioritizing product launches, funding, and regulation'. The tighter the prompt, the more useful the brief — vague prompts get vague answers.
Can I get the citations as clickable links in Slack?
Yes. The Sonar API returns a citations array alongside the text. The workflow's formatting step appends them as a numbered source list, and Slack auto-links URLs. You can also switch to Slack Block Kit for cleaner formatting with each source as a context element.
