Can AI compare products for me?

Yes, if you paste the specs or listings. It compares them on the features that matter for how you'll use the thing and tells you what would change its pick.

Replace everything in [BRACKETS] with your own details, then paste it into your AI app.

prompt.txt
You are an independent product reviewer with no brand loyalty.

What I'm buying: [PRODUCT TYPE]

How I'll use it: [USE]
Budget: [AMOUNT]

Your task: compare my options.

Rules:

- MUST use only the specs I pasted; mark missing ones 'check the listing'.
- NEVER state prices or ratings that aren't in what I pasted.
- If anything is missing, ask me up to 3 short questions first.

Give me: a comparison table, your pick, and the one thing that would change it.

03Steps

  1. Copy the spec section from each listing.
  2. Paste them into the prompt with how you'll use it.
  3. Double-check the winner's specs on the store page.

04What can go wrong

  • Listings can be wrong or out of date.
  • AI may not know about very new models.

05What to use

Any major AI chat app.

06Our test runs

2 runs, each with a different made-up sample. 2 of 2 passed every check.

Run 1 · Llama 3.3 70B · graded by GPT-OSS 120BOct 4, 2026Passed

The made-up sample:

  • [PRODUCT TYPE]Wireless noise‑cancelling over‑ear headphones
  • [OPTIONS]1. **SoundWave X200** – Bluetooth 5.2, 30 h battery, 250 g, Adaptive ANC (up to 35 dB), 40 mm drivers, USB‑C fast charge (5 min = 2 h), built‑in mic, supports AAC & SBC. 2. **AudioPulse Pro 3** – Bluetooth 5.0, 28 h battery, 260 g, Hybrid ANC (up to 32 dB), 42 mm drivers, micro‑USB charge, multipoint pairing, supports aptX, SBC. 3. **Zenith QuietFit** – Bluetooth 5.1, 35 h battery, 240 g, Passive + ANC (up to 30 dB), 38 mm drivers, USB‑C, voice assistant button, supports AAC, aptX‑LL, SBC.
  • [USE]Daily commute on trains and buses, occasional long‑haul flights, and listening to podcasts and music at home. Need strong noise cancellation for crowds, comfortable fit for many hours, and reliable Bluetooth connectivity.
  • [AMOUNT]$250
  • Compare only on relevant features and explain why each matters
  • Use only pasted specs; mark missing ones
  • Never state prices or ratings not in the paste
  • Provide comparison table, pick, and one thing that would change it
  • Didn't make up details we never gave it

What came back (excerpt):

Based on your requirements, my pick is the **SoundWave X200**. It offers the strongest noise cancellation (up to 35 dB), which is essential for blocking out crowds during your daily commute and flights.
Read the full answer
To compare the options, I'll focus on features that matter for your use: noise cancellation, comfort (weight), battery life, Bluetooth connectivity, and audio quality (driver size).

Here's the comparison table:

| Model | Noise Cancellation (dB) | Weight (g) | Battery Life (h) | Bluetooth Version | Driver Size (mm) |
| --- | --- | --- | --- | --- | --- |
| SoundWave X200 | up to 35 | 250 | 30 | 5.2 | 40 |
| AudioPulse Pro 3 | up to 32 | 260 | 28 | 5.0 | 42 |
| Zenith QuietFit | up to 30 | 240 | 35 | 5.1 | 38 |

Based on your requirements, my pick is the **SoundWave X200**. It offers the strongest noise cancellation (up to 35 dB), which is essential for blocking out crowds during your daily commute and flights. Its battery life (30 hours) is sufficient for long-haul flights and daily use. The Bluetooth 5.2 version ensures reliable connectivity. Although it's not the lightest option, its weight (250 g) is still relatively comfortable for extended wear.

The one thing that would change my pick is if the **Zenith QuietFit** had stronger noise cancellation. If it could match or exceed the SoundWave X200's noise cancellation, its longer battery life (35 hours) and lighter weight (240 g) would make it a more attractive option.

Before finalizing, I have a few questions to ensure I've considered all relevant factors:
1. Are you particular about the type of noise cancellation (Adaptive, Hybrid, or Passive + ANC)?
2. Do you have a preferred audio codec (e.g., AAC, aptX, SBC)?
3. Is the voice assistant button on the Zenith QuietFit a significant feature for you?

Check that no unprovided specifications are introduced.

The made-up sample (a messier one):

  • [PRODUCT TYPE]Wireless noise‑cancelling headphones
  • [OPTIONS]Option 1 – Brand A Model X1: Over‑ear, Active Noise Cancelling, 30 h battery life, Bluetooth 5.2, 40 mm drivers, weight 260 g, mic with wind‑noise reduction, USB‑C charging, price $229. Option 2 – Brand B SoundPro 300: Over‑ear, Hybrid ANC, 20 h battery, Bluetooth version: check the listing, 38 mm drivers, weight 280 g, mic with AI noise cancellation, USB‑C charging, price $199. Option 3 – Brand C QuietBeat: On‑ear, Passive ANC, 25 h battery, Bluetooth 5.0, 35 mm drivers, weight 210 g, basic mic, micro‑USB charging, price $179.
  • [USE]I take the train 45 minutes each way, work from home a few days a week, and like to watch movies on my laptop. I need solid NC for the train, a decent mic for calls, and at least 20 h battery. Over‑ear is fine but I don’t want them too heavy.
  • [AMOUNT]$250
  • Compare only features that matter and explain why
  • Use only pasted specs; mark missing as 'check the listing'
  • Never state prices or ratings not in the paste
  • Provide table, pick, and one thing that would change it
  • Didn't make up details we never gave it

What came back (excerpt):

To compare the options effectively, I'll focus on features that matter for your use: solid noise cancellation (NC) for the train, decent mic for calls, at least 20 hours battery life, and a comfortable weight since you'll be wearing them for your daily commute and work.

Here's a comparison table based on the provided specs:

| Feature | Option 1 - Brand A Model X1 | Option 2 - Brand B SoundPro 300 | Option 3 - Brand C QuietBeat |
| --- | --- | --- | --- |
| Noise Cancellation | Active NC | Hybrid ANC | Passive ANC |
| Battery Life | 30 hours | 20 hours | 25 hours |
| Mic | Wind-noise reduction | AI noise cancellation | Basic mic |
| Weight | 260 g | 280 g | 210 g |
| Bluetooth Version | 5.2 | check the listing | 5.0 |

Given your requirements:
- **Noise Cancellation**: Active or Hybrid ANC is preferable for better noise reduction, especially on the train. Matters because it directly affects your ability to focus or enjoy media without ambient noise.
- **Mic**: A decent mic with noise cancellation features (like wind-noise reduction or AI noise cancellation) is important for clear calls. Matters because you need to make calls and be heard clearly.
- **Battery Life**: At least 20 hours to cover your commute and work hours without needing a recharge. Matters because you don't want your headphones dying during use.
- **Weight**: Over-ear is acceptable, but lighter is preferable for comfort. Matters because heavy headphones can be uncomfortable during extended wear.

**Pick**: Based on the specs, Option 1 - Brand A Model X1 seems to be the best fit. It offers active noise cancellation, a long battery life of 30 hours, a mic with wind-noise reduction for clearer calls, and while it's not the lightest, its weight is still manageable at 260 g.

**One thing that would change it**: If Option 2 - Brand B SoundPro 300 had Bluetooth 5.2 (or at least confirmed to be a recent version) and weighed less than 260 g, it could potentially be a better option due to its hybrid ANC and AI noise cancellation mic, which might offer superior call quality and noise reduction in certain environments. However, without the Bluetooth version and considering the slightly heavier weight, Option 1 remains the top choice.

Watch that no price information is included and missing specs are flagged as 'check the listing'.

How each run works: we fill the prompt with a made-up sample, run it once in Llama 3.3 70B, and GPT-OSS 120B grades the answer against the prompt's own rules. Word limits are counted by code, and every quote flagged as made up is checked against the full answer. Your results can differ. How we test.
