LADLE vs Perplexity — for citation-heavy work.

Perplexity built its whole product around inline citations. Every answer is annotated with source links, and the primary interface is a search-style query box. LADLE is a chat assistant that cites when web search fires. These are meaningfully different product patterns.

**Perplexity's strengths.** Citation-per-claim density is higher. The UI is optimized for verifying every sentence against a source. For "answer this question with sources I can hand to my editor," Perplexity is a good default. The Pro tier costs $20/mo.

**LADLE's strengths.** Multi-turn conversation is smoother — LADLE remembers what you asked three turns ago, Perplexity's chat mode is thinner. For extended research where you're refining questions across a session, chat structure wins. Also: Claude Sonnet is a stronger writer than most search-first models, so if the OUTPUT of your research is prose, LADLE's replies are usable as first drafts more often.

**When to pick Perplexity.** Fact-checking a specific claim, source-hunting for a specific citation, quick research where citation-density > conversational depth, competitive research where you need to trace every claim to a URL.

**When to pick LADLE.** Multi-turn research sessions, research that ends in a written deliverable, working through complex reasoning where citations matter but aren't the primary output, or when you want the meal-donation social contract in your $20/mo AI spend.

**Can you use both?** Yes. A common pattern: Perplexity for the initial fact-hunt (find the sources), LADLE for the synthesis (turn the sources into a written brief). $40/mo total, and they don't overlap much.

**What's actually different structurally.** LADLE's $20 sends $8 to WFP with a public receipt. Perplexity's $20 stays entirely within Perplexity's business. If the structural commitment matters, LADLE. If not, they're both solid — different products.
