# Live trend research

> The web's lag and the chat-LLM's training cutoff make 'what's happening this week' research painful. Grok pulls live X chatter, Perplexity grounds in cited sources, Claude turns the two streams into a 5-bullet brief you can hand a colleague. 30-min weekly habit replaces 4 hours of tab-switching.

## The tools

### Grok — Live X + xAI search

- Pricing: $30/mo SuperGrok · $40/mo X Premium+ (X bundled)
- Site: https://grok.com
- Why this one: Real-time access to X with native search. The signal Perplexity and Claude can't reach. Bundled with X Premium+ at $30/mo, so if you already have the X subscription, the research add-on is free.
- Swap in instead: ChatGPT

### Perplexity — Cited primary sources

- Pricing: $20/mo Pro · API tier-based
- Site: https://perplexity.ai
- Why this one: Grok tells you what people are saying; Perplexity tells you what actually happened (with links). Pair them: catch the wave from Grok, verify from Perplexity.

### Claude — Synthesis into a brief

- Pricing: Free · $20/mo Pro · $100/mo Max 5x · $200/mo Max 20x · Sonnet API $2/$10 per M tokens (input/output)
- Site: https://claude.ai
- Why this one: Long-context turn that takes both feeds and outputs a 5-bullet brief. Same prompt every week makes the briefs comparable.

## Workflow

### 1. Live pulse from Grok (Grok)

Ask Grok what people are saying about your topic this week, with a real-time anchor.

**Prompt: Live trend pulse on Grok**

```
What is X actually saying about {{topic}} in the last 7 days?

Output, in this order:
1. **Three angles** people are arguing about — what's the disagreement, who's on each side, ~2 representative posts each (with handles).
2. **One contrarian read** — a post from a credible voice that pushes against the consensus this week.
3. **Two under-radar things** — observations from accounts under 50k followers that the larger accounts haven't picked up yet.
4. **Volume signal** — is this topic trending, holding, or decaying compared to last week?

Cite handles and post links. No paraphrased filler. No "experts say".
```

### 2. Verify with Perplexity (Perplexity)

For each angle from Grok, pull the underlying primary source. Don't synthesize on rumor.

### 3. Synthesize with Claude (Claude)

Both outputs into Claude. One brief out the other side.

**Prompt: 5-bullet weekly trend brief**

```
Synthesize the two inputs below into a brief I can read in 90 seconds.

Live pulse (Grok output):
"""
{{paste Grok output}}
"""

Cited sources (Perplexity output):
"""
{{paste Perplexity output with links}}
"""

Output (in this order, ready to paste into a doc or Slack):

1. **TL;DR** — one sentence, the single thing I should know this week.
2. **What's actually happening** — 2 to 3 bullets, each with a date and a primary-source link.
3. **What people are arguing about** — 1 to 2 bullets, each with a representative quote.
4. **The under-radar story** — 1 bullet on something the big outlets missed.
5. **What changed since last week** — 1 to 2 bullets, comparison to the prior brief.

Constraints:
- Every bullet has a name, date, or number.
- No "in the rapidly evolving landscape", no "experts say", no "could have implications for".
- No em dashes.

Output as Markdown.
```

## What it produced

**Solo VC analyst, weekly habit**

Replaced ~4 hours of tab-switching with a 30-min Friday habit. The Grok step caught a sentiment shift on a portfolio company 2 days before the public-news cycle. The combined brief now circulates internally; partners who used to skim Twitter manually skip that pass entirely.

## Pitfalls

- **Treating Grok's pulse as truth** — X-trending isn't reality. The Perplexity step exists to ground the noisy signal. Skipping it means publishing rumor.
- **Brief format drift week-over-week** — The value compounds when briefs are comparable across weeks. Lock the prompt + the structure; only change after a quarter.
