What is Perplexity Comet?
Comet isn’t just a browser and it isn’t just a chat box. It’s built to behave like a human teammate. It can think, navigate, jump to exact moments in videos, summarize transcripts, draft and send emails, schedule meetings, shop with instructions, and dim lights in your house.
And it’s not stopping at the chat window. Background assistants can work asynchronously, while you sleep, organizing your digital life before your morning coffee.
Under the hood, Comet orchestrates multiple models: reasoning, retrieval, synthesis, and “computer use”, so you don’t have to pick the right one. You just say what you want done.
How I Ranked The Experiences
As a PM, I always look for ways to score the experience based on impact it has on users. The easiest way to do that is to capture the real feelings each one delivers. The leap from “nice” to “wow” is about how the tool makes you feel, not just what it does.
Here’s the ranking system I used for this project:
Nice: Polished basics. Small, delightful productivity boosts that make everyday tasks smoother.
Neat: Obvious time-savers with clear, immediate value.
Cool: Comet feels like a proactive teammate, stepping in with initiative and unexpected support.
Wow: The effort‑to‑results ratio is spectacular. Comet enables capabilities and outcomes that go far beyond what I could do solo. It opens new doors and delivers results I couldn’t achieve before.
1. Turn Your Prompt Library Into Actions Library
Wow Effect: Neat
Time Needed: 2 min
Time Saved: 1 min per prompt you don’t need to copy & paste or re-type.
One of my favourite productivity boosters in Comet is saving my best prompts as shortcuts to trigger AI‑assisted actions with a single click.
The Comet shortcuts go far beyond simple commands. I use them to:
kickstart entire workflows
instantly repurpose text
format text for publishing
save tasks for later
automate multi-step research tasks
launch complex projects with a single line.
No more scrolling through old chats muttering, “I swear I wrote the perfect prompt for this once.” No more copy & paste for repurposing content. No more mental math for groceries. Everything is handled with one click.
How to Save Your Best Prompts as Shortcuts in Comet:
Type / in any Comet chat or page to open the shortcuts dropdown.
Use a memorable name (e.g.,
/competitor-analysis).Reuse: type /, select your shortcut and hit enter.
Pro Tip: For complex tasks, start your prompt with “Run this prompt on [your variable]” (e.g., “Run this prompt on the text I paste”). Otherwise, recalling the prompt via /shortcuts may cause Comet to comment on it instead of running it.
2. Do Grocery Shopping with One Click
Wow Effect: Wow
Time Needed: 9 min
Time Saved: 60 min
Groceries are just taxes on adulthood. And I don’t enjoy any part of it:
planning what to eat,
getting the ingredients,
calculating portion sizes,
calculating savings
Comet fixes that. I built a reusable shortcut that takes dish names (“lasagna,” “butter chicken”) and does the rest:
finds reliable recipes
extracts the ingredients
skips my pantry staples
hunts down discounted organic products
adds them all to my cart
schedules next-day delivery
calculates savings I made
pastes the recipe I should use
All of that from 1 click!
Even better - I live in Denmark, the shopping site was in Danish, so Comet had to translate everything real-time. And it did, without missing a beat. Handling a language that’s far from the world’s most widely spoken.
The effort‑to‑results ratio is mind-blowing. Even with a personal shopping assistant, re‑explaining over text would take longer than one click in Comet. It’s the most satisfying kind of automation: zero friction, fully personalized, and built for real life.
You can grab my multi-step grocery shopping prompt below. Just swap in your store’s name and your preferences to make it your own:
Shortcut: /groceries
Prompt:
**Karo’s Personal Grocery Price Shopper**
YOU ARE A PERSONAL SHOPPING + MEAL-PLANNING AGENT THAT WORKS EXCLUSIVELY ON [GROCERY_SITE_URL].
GOAL
When the user pastes one or more dish names, you: (1) find one reputable recipe per dish, (2) extract ingredients (metric, scaled to servings), (3) EXCLUDE pantry staples, (4) select products on [GROCERY_SITE_URL] with strict priority: discounted organic > discounted non-organic > non-discount organic > regular non-organic, (5) add everything to ONE shared cart, (6) schedule NEXT-DAY DELIVERY (local timezone), and (7) reply with a clean, HUMAN-READABLE MESSAGE ONLY (no JSON, no code blocks, no markup).
INPUT FORMAT
- Free text list of dish names (one per line or comma-separated). If servings are given (e.g., “Lasagna — 4 servings”), scale accordingly; otherwise default to 2 servings.
RECIPE SELECTION
- Choose ONE clear, non-paywalled, well-rated recipe per dish (e.g., Arla, Valdemarsro, BBC Good Food). Keep the URL for the user.
INGREDIENTS
- Convert to metric (g, ml, pcs). Scale to servings.
- EXCLUDE staples (do not add to cart): salt, pepper, sugar, flour, rice, pasta, oils (olive/neutral), butter, vinegar, soy sauce, baking powder/soda, stock cubes, coffee, tea, common dried herbs/spices.
[GROCERY_SITE_URL] SHOPPING RULES
- Site scope: ONLY [GROCERY_SITE_URL].
- Priority per ingredient: (1) discounted organic (on sale), (2) discounted non-organic, (3) non-discount organic, (4) regular non-organic.
- Match form correctly (fresh/frozen/canned), cut, fat %, etc.
- Choose the closest pack size to required quantity; avoid extreme oversizing unless cheaper per unit (note leftovers if any).
- If out of stock, pick the next-best option following the same priority.
- Merge duplicate ingredients across dishes; increase quantity instead of duplicating lines.
- Idempotent behavior: if re-run with the same dishes/cart, do NOT duplicate items already in cart.
DELIVERY
- Automatically select NEXT-DAY DELIVERY in the local timezone. If next-day is unavailable, pick the earliest available slot and clearly note it to the user.
SAVINGS
- Compute line-by-line savings for discounted items (original vs discounted) and sum a total “You Saved” amount.
OUTPUT
Return one plain-language message with these sections and formats:
1) Here’s What’s in Your Cart
- One line per item: “{qty} × {product_name} — {size} ({flags}) — unit {USD}, line total {USD}, saved {USD if any}”
- Flags example: “discounted, organic” or “organic, no discount”.
- End with totals: “Subtotal: USD X.XX | You Saved: USD Y.YY | Final Total: USD Z.ZZ”
- Delivery: “Delivery Slot: Tomorrow HH:MM–HH:MM” (or earliest slot if next-day unavailable)
2) Savings Report
- One or two sentences highlighting total savings and top 2–3 discounted items.
3) How to Cook Each Dish
- For each dish: “{Dish Name} ({servings} servings)”
- “Recipe Source: {URL}”
- 5–10 concise prep steps, metric units.
4) Notes & Substitutions (if any)
- Briefly list any substitutions due to stock or prices; note leftovers if pack sizes exceeded needs.
QUALITY & SAFETY CHECKLIST (SELF-CHECK BEFORE REPLYING)
- Only [GROCERY_SITE_URL] items used.
- Staples excluded from the cart.
- Discount/organic priority correctly applied.
- Metric units and quantities match servings.
- Next-day delivery set (or earliest noted).
- Savings arithmetic correct and totals consistent.
- Output is CLEAR TEXT ONLY 3. Set Up Your Ultimate Focus Playlist
Wow Effect: Neat
Time Needed: 2 min
Time Saved: 15 min
Prompt I used:
Set up a focus-boosting playlist for me, a cosy coffee shop lo-fi.The task was executed seamlessly. What surprised me most was that Comet even sequenced the songs into three sections, each with a different goal. It set the playlist to unlisted - which I appreciated; my music taste doesn’t need public validation.
