Promptwatch vs Otterly.AI (2026): Cheapest Entry or Broadest Platform?
Otterly.AI's $29/mo is the genuinely cheaper entry point. Here's what Promptwatch's higher starting price adds, and when the extra cost is worth it.
Promptwatch and Otterly.AI both come up when a team wants AI visibility tracking without a procurement process, but they aren't priced the same way. Otterly's Lite plan genuinely starts at $29/mo. Promptwatch Essential starts at $95/mo, with a free Explore tier available for very limited testing. Essential combines prompt tracking with citation analytics, visitor analytics, and content generation. AI crawler-log monitoring begins on Professional at $245/mo.
Quick take: Otterly.AI wins on price and setup speed. Its $29/mo Lite plan and no-card trial make it the cheaper way to find out whether AI visibility tracking matters for your brand. Promptwatch Essential costs $95/mo and includes the broader engine set, citation analytics, 200K visitor events, and five AEO articles. Professional at $245/mo adds AI crawler-log tracking.

What the entry price actually gets you on each
On Promptwatch, the free Explore tier covers ChatGPT only, 10 prompts, one project, and one seat, enough to see the interface, not run a program. The first paid tier, Essential at $95/mo, unlocks the full engine set (ChatGPT, Gemini, Claude, Perplexity, Grok, Llama, DeepSeek, Mistral, and Copilot, plus Google AI Overviews and AI Mode), 50 prompts, 6,000 responses, 200,000 visitor events, and five AI-generated AEO articles a month through Content Agents.
On Otterly, $29/mo is the Lite plan: 15 prompts across four base engines, refreshed on a cadence users describe as closer to weekly than daily. Gemini, Claude, and AI Mode aren't included at all here; they're add-ons priced from $9 to $149/mo depending on the tier you're on. Fifteen prompts is enough to see whether the category matters for your brand. It's not enough to run a program on, and it costs a third of Promptwatch's first paid tier.
Speed of setup
This is genuinely close, and it's the one place Otterly has an edge on top of its lower price. Its onboarding is built to get a first dashboard in front of you inside an hour, and the free trial requires no credit card, which removes the last bit of friction between curiosity and data. Promptwatch's setup is also self-serve and fast, typically live the same morning you connect a domain, but Otterly's flow is a notch more polished for a first-time buyer who has never used a tracker before.
Where the gap widens: coverage and evidence
Once you are past the demo, the comparison shifts from price to scope. Otterly's own users report monitoring data lagging up to a week, so a change on Tuesday might not surface until the following Monday. Promptwatch Essential refreshes daily and documents citations at the page, domain, Reddit, and YouTube level. It also includes visitor-level conversion tracking. Professional adds real-time AI crawler logs. That depth is not free, and Promptwatch's cheapest paid plan costs more than three times Otterly's Lite plan.
Pricing past the entry tier
Promptwatch's next step is Professional at $245/mo, adding a second project, more prompts and responses, AI crawler-log tracking (Agent Analytics), and 15 AEO articles a month. Business at $579/mo scales further. Agency plans start at $199/mo (Kick-off, self-serve, unlimited client projects and prompts, 10 seats).
Otterly's ladder climbs differently: Standard at $189/mo gets 100 prompts, API access, and Looker Studio export, and Premium at $489/mo covers 400 prompts. Add the engine add-ons ($9 to $149/mo for Gemini, Claude, and AI Mode) and a full-coverage Otterly setup can approach Promptwatch's mid-tier pricing, though Otterly's entry point stays cheaper at every comparable scale.
Who should pick which
Otterly is the better, cheaper first stop if you want to prove AI visibility tracking matters before committing real budget, its $29/mo Lite plan and no-card trial are hard to beat on cost, and the four base engines are enough to see a baseline.
Promptwatch costs more from day one, but it's the better pick once you need a broader engine set, real citation analytics, AI crawler-log visibility, and a content-generation layer inside the same platform, capabilities Otterly doesn't offer regardless of tier. Starting with Otterly and moving to Promptwatch once you outgrow a narrow tracker is a reasonable path for a lot of teams, too.
FAQ
Is Otterly's free trial actually free?
Yes. It's a genuine no-credit-card trial running roughly two weeks, covering the four base engines. You can see real data before deciding whether to pay for anything.
Why does Otterly's data lag if it's checking daily?
The company doesn't publish an exact reason, but users consistently report monitoring data up to seven days stale and new prompts taking time to populate. Treat Otterly as weekly intelligence rather than a live feed unless you've personally verified faster refreshes on your account.
Does Promptwatch have a free trial?
Yes, Promptwatch offers a free Explore tier (10 prompts, ChatGPT only, no card required) as well as a 7-day trial on paid plans like Essential. That's more flexible than Otterly's single no-card trial, though Otterly's trial covers a slightly wider slice of a paid-equivalent experience out of the box.
Which one should an agency pick?
Depends on budget and required breadth. Promptwatch's self-serve Agency Kick-off tier (from $199/mo) covers unlimited client projects and prompts across 10 seats, along with crawler-log and citation analytics per client. Otterly's Standard and Premium tiers cost less at small scale, but engine add-ons and prompt-pack pricing make the real cost harder to predict once you multiply across several client accounts.
