Research and Draft Short Social Media Captions with Perplexity

Open Perplexity and start a new thread

Open Perplexity in your browser or app, then sign in if prompted. Look for a "New Thread" button or a clean search box at the top of the screen — it usually has placeholder text like "Ask anything…" or "What do you want to know?". Click or tap inside the box. The cursor blinks, ready for typing.

Each Perplexity conversation is called a "thread", so starting fresh keeps your research tidy.

Ask Perplexity to research trending angles for your topic

Type a clear, specific question into the search box. Beating your hands at the keyboard here won't help — give Perplexity a topic, an audience, and a goal in plain English. After you press Enter (or tap the arrow icon), Perplexity starts writing a short answer with numbered footnotes — those tiny superscript numbers are links to the sources it used. Below the answer, you'll often see a list of related questions you can click for a deeper dig.

If the answer feels too generic, try the "Focus" dropdown (look for buttons labeled Web, Social, Academic, or All) — switching to Social tells Perplexity to lean on posts and trending discussions rather than formal articles.

Next step ↓

Pick one angle and ask for supporting facts

Scroll through the answer and choose one angle that excites you — don't try to cover all five. Click the related question that matches your pick, or type a new follow-up question into the same box. A new answer appears below the first, still with its own numbered sources. The conversation history stays visible, so you can scroll up and compare.

If a footnote link looks interesting, click it — Perplexity opens the source in a new tab. Don't worry about reading every word; skim for a quote, a stat, or a phrase you might want to mention.

Next step ↓

Switch into "drafting mode" with a clear instruction

Now you've done the research — time to write. Stay in the same Perplexity thread and type a new prompt. This time, you're telling Perplexity to write, not research. Be specific about the platform, length, tone, and what facts to include. Perplexity drafts a caption right inside the chat.

If the tone feels off, try adding words like "warm", "playful", "matter-of-fact", or "professional" to your instruction. Perplexity works best when you tell it exactly how the caption should sound.

Next step ↓

Refine the draft in the same conversation

Read the caption out loud — does it sound like you? If a sentence feels clunky, type a quick refinement request right below the draft. Perplexity updates the answer in place, and the old version scrolls up so you can compare. This back-and-forth is normal and usually takes 2–3 quick rounds.

If Perplexity suggests adding emojis and you'd rather skip them, just say so. The same goes for hashtags — you can ask it to suggest 3–5 relevant ones or to leave them out entirely.

Next step ↓

Save your sources and copy the caption

Before you leave Perplexity, capture the footnote links from Steps 2 and 3 — you may want to credit a source in your post, or come back to read more later. Look for the small numbered superscripts next to sentences; click them to copy the URL from your browser's address bar.

Then copy the caption itself. Look for a small copy icon (two overlapping squares) near the draft, or simply highlight the text with your mouse or finger and copy it. Paste it straight into Instagram, LinkedIn, X, or your scheduling tool.

If Perplexity's Pro plan would help you here, note that the free plan has a daily cap on Pro searches, but regular searches are unlimited for most users — you can complete this whole guide on the free tier.
