Key takeaways
- Peec AI and Promptwatch both start near $95/mo for roughly 50 prompts, but Peec AI caps you at 3 of 6 engines on every self-serve tier while Promptwatch lets you pick 4 from 8 at the same price point.
- Brandlight has no public pricing. Expect a paid pilot before you see a contract, with third-party estimates ranging from around $199/mo on the low end to $4,000-$15,000/month for full enterprise deployments.
- Only Promptwatch in this trio ships crawler logs, content gap analysis, and automated content generation. Peec AI and Brandlight monitor; only one of the three closes the loop into action at self-serve prices.
- AI answers are non-deterministic. Running the same 50 prompts through three tools on three different days will produce three different "visibility scores" even if nothing on your site changed, so treat any single snapshot with suspicion.
- Brandlight rates highest on G2 (4.9/5) but takes an average of 2 months to implement, according to G2's own user data. Peec AI and Promptwatch are both self-serve and live within a day.
Why this comparison is harder than it looks
I want to get the caveat out of the way first, because it changes how you should read everything below. AI search results are not stable. Ask ChatGPT the same question twice in the same afternoon and you can get two different sets of cited sources. That's not a bug in any of these three tools, it's how retrieval-augmented generation works when the underlying index and sampling window keep shifting.
So when I say I tested Brandlight, Peec AI, and Promptwatch on the same 50 prompts, I mean I set up identical prompt lists in each platform, pointed them at the same brand and the same three-week window, and compared what came back. I did not expect, and did not get, identical "visibility scores" across the three. What I got was three different lenses on the same underlying reality, and that's actually the more useful finding. One evaluator summed up the risk well: a CMO quoted by a tooling review site said she "ran the same queries manually and got different results" than what her tool reported. That's the baseline noise level you're working with before you even compare vendors.
With that said, here's what actually differed.
The three platforms, in one table
| Brandlight | Peec AI | Promptwatch | |
|---|---|---|---|
| Entry pricing | No public price, quote-based, typically a paid pilot | $95/mo (Starter) | $95/mo (Essential) |
| Prompts on entry tier | Custom, enterprise scoping | 50 | 50 |
| Engines tracked | Adapts per market; claims 13 engines company-wide | 3 of 6-7 (4th engine is a paid add-on) | 4 of 8 at entry, 11 available on Agency plans |
| Crawler logs | Not publicly listed as a feature | No | Yes, from Professional plan |
| Content gap analysis | Yes, via multi-agent content engine | No | Yes, higher tiers |
| Auto-publish to CMS | No, routes to CMS for human/legal review | No | Yes, Webflow/Framer/WordPress |
| Free trial | No, paid pilot model | 7-day trial (older pricing structure) | 7-day trial on Essential |
| G2 rating | 4.9/5 (236 reviews) | Not independently verified in this test | 4.7/5 (1,780+ customers) |
| Best fit | Multi-brand enterprises with budget for a dedicated team | Budget-conscious SEO teams wanting clean reporting | Teams that want monitoring plus the fix |
Round one: engine coverage and prompt volume
This is where the gap showed up fastest. Peec AI's Starter, Pro, and Advanced tiers all cap you at three of six or seven possible engines. Want a fourth engine like Claude or Grok? That's a paid add-on running $35/mo on Starter up to $165/mo on Advanced. So the "$95/mo for 50 prompts" headline price doesn't include the engine mix most brands actually care about today.
Promptwatch's equivalent tier, Essential at $95/mo, gives you 4 of 8 models to choose from (OpenAI, Perplexity, Google, Claude, Gemini, Meta, DeepSeek, Grok) for the same 50 prompts and no separate add-on fee for the fourth model. On Promptwatch's Agency plans, you get access to all 11 supported platforms, including newer surfaces like AI Mode and coding assistants.
Brandlight doesn't publish a fixed engine list at all. Per its own materials, coverage is
