Key takeaways
- Hall AI has shut down, leaving users scrambling for a replacement in the fast-moving GEO/AI visibility space
- The main alternatives split into two camps: monitoring-only tools (Otterly.AI, Peec AI) and full optimization platforms (Promptwatch)
- If you just want to see where your brand shows up in AI answers, Otterly.AI or Peec AI will do the job at a lower price point
- If you want to actually improve your AI visibility — not just watch it — Promptwatch is the only platform in this comparison that closes the loop from gap analysis to content creation to tracking
- Price matters: Otterly.AI and Peec AI are cheaper entry points, but neither helps you act on what they show you
Why former Hall AI users are searching for alternatives right now
Hall AI built a following among marketers who wanted to track how their brand appeared in AI-generated answers. The platform had a clean interface, covered the major LLMs, and gave teams a way to at least see what was happening as AI search exploded.
Then it shut down.
The r/geotoolsreview community has been active with threads asking exactly this question: "Have you already found a replacement? Are you moving to Radarkit or something else? What features from Hall AI are you going to miss the most?" The honest answer is that Hall AI was a monitoring tool, and there are several monitoring tools that can replace it. But the more interesting question is whether you want to just replace what Hall did — or actually use this transition as a chance to upgrade.
Because the GEO space has moved fast. The tools that existed when Hall launched have been lapped by platforms that don't just show you data but help you do something with it.
Here's the honest breakdown.
The four tools compared
Before diving into features, here's a quick orientation on what each tool actually is:
- Promptwatch: End-to-end AI visibility and GEO platform. Tracks visibility, finds content gaps, generates content to fill them, and measures results.
- Peec AI: AI visibility tracker focused on prompt-level monitoring across ChatGPT, Perplexity, Claude, and Gemini using UI scraping.
- Otterly.AI: Lightweight AI search monitoring tool covering brand mentions across ChatGPT, Perplexity, and Google AI Overviews.
- Hall AI: (Defunct) AI brand monitoring platform that tracked LLM mentions and citations.

Promptwatch: the option that goes beyond monitoring
Promptwatch is the most complete platform in this comparison by a significant margin. It's the only one that treats AI visibility as something you can actively improve, not just observe.
The core difference comes down to what happens after you see the data. With Peec AI or Otterly.AI, you get a dashboard showing where your brand appears (or doesn't). That's useful, but it leaves you with a question: "OK, so what do I do now?"
Promptwatch answers that question with three connected capabilities:
Answer Gap Analysis shows you exactly which prompts your competitors are visible for that you're not. Not vague categories — specific questions and topics that AI models are already answering, where your content is absent. You can see the gap, understand why it exists, and prioritize which ones are worth closing.
Content Agents then generate articles, listicles, comparisons, and briefs grounded in that real prompt data. These aren't generic AI-written posts — they're built from citation data, prompt volumes, competitor analysis, and brand guidance. The output is content engineered to answer the specific gaps AI models have already exposed.
Page-level tracking closes the loop. You can see which pages are being cited, by which models, how often, and when a newly published page moves from "crawled" to "cited." The AI Crawler Logs feature is particularly useful here — it shows real-time logs of when ChatGPT, Claude, Perplexity, and others hit your site, which pages they read, and what errors they encounter.
For former Hall AI users, this represents a meaningful upgrade. Hall showed you what was happening. Promptwatch shows you what's happening and gives you the tools to change it.
Pricing starts at $99/month for the Essential plan (1 site, 50 prompts, 5 articles). The Professional plan at $249/month adds crawler logs, state/city tracking, and more content generation capacity. There's a free trial available.
The one honest caveat: Promptwatch is more platform than some teams need right away. If you're a solo marketer who just wants to check in on brand mentions once a week, the full feature set might feel like more than you'll use. But if you're serious about AI search visibility as a channel, it's the right tool.
Peec AI: solid monitoring with real UI-level tracking
Peec AI is a genuine alternative for teams that want reliable monitoring without the complexity of a full optimization platform.
What Peec AI does well: it uses UI scraping rather than API calls to track AI responses. This matters because user-facing answers in ChatGPT or Perplexity can differ from what you'd get through an API. You're seeing what actual users see, which makes the data more representative.
Coverage includes ChatGPT, Perplexity, Claude, and Gemini. You can track prompts, see citation data, and benchmark against competitors. The interface is clean and the onboarding is straightforward. Pricing starts around €89/month with a 7-day trial.
Where Peec AI falls short for former Hall users: it doesn't help you do anything with what you find. There's no content gap analysis, no content generation, no crawler logs, no traffic attribution. You get the monitoring layer and that's it. If Hall AI's monitoring was what you valued, Peec AI replicates it reasonably well. If you wanted more than Hall offered, Peec AI won't get you there.
Otterly.AI: lightweight and focused
Otterly.AI sits at the simpler end of the spectrum. It covers ChatGPT, Perplexity, and Google AI Overviews, tracks brand mentions, and gives you a basic view of your AI search presence.
Otterly.AI
For teams that are just starting to think about AI visibility — or for smaller businesses that want a low-cost way to keep an eye on things — Otterly.AI is a reasonable starting point. The interface is approachable and the barrier to entry is low.
The limitations are real, though. Coverage is narrower than Peec AI (no Claude or Gemini tracking). There's no content optimization, no gap analysis, no crawler data. It's a monitoring dashboard, full stop.
For former Hall AI users, Otterly.AI is probably the closest like-for-like replacement in terms of scope and simplicity. If Hall AI was doing the job for you and you just need something similar at a comparable price, Otterly.AI is worth a look. If you were frustrated by Hall's limitations, Otterly.AI won't fix them.
How to choose: a practical decision framework
The right choice depends on what you actually need from a GEO tool.
Choose Otterly.AI if:
- You want the simplest possible replacement for Hall AI's monitoring
- Budget is the primary constraint
- You're tracking a single brand across the three main AI engines
- You don't need to act on the data, just observe it
Choose Peec AI if:
- You want more accurate UI-level tracking (not just API data)
- You need Claude and Gemini coverage in addition to ChatGPT and Perplexity
- You want slightly deeper competitor benchmarking than Otterly.AI offers
- You're comfortable with a monitoring-only workflow
Choose Promptwatch if:
- You want to actually improve your AI visibility, not just track it
- You need content gap analysis to know what to create next
- You want AI crawler logs to understand how models discover your site
- You're managing multiple brands or sites
- You need traffic attribution to connect AI visibility to revenue
- You want ChatGPT Shopping tracking, Reddit/YouTube insights, or query fan-outs
The honest summary: if Hall AI was doing enough for you and you just need a replacement, Otterly.AI or Peec AI will cover the basics. If Hall AI's limitations were part of why you're reconsidering your stack, this is the moment to move to a platform that can actually help you rank in AI search — not just watch your competitors do it.
What the broader market looks like
It's worth noting that this comparison covers only a slice of the GEO tools market. There are now 28+ platforms tracking AI visibility in some form, ranging from enterprise-focused tools like Profound and Scrunch to newer entrants like Rankshift and LLM Pulse.
Profound
Most of them share the same fundamental limitation as Otterly.AI and Peec AI: they show you data but leave you to figure out what to do with it. The platforms that have moved beyond monitoring — Promptwatch being the clearest example — are the ones worth paying attention to as AI search continues to take share from traditional Google results.
The Omnia team published a useful comparison of 28 platforms earlier this year that's worth reading if you want a broader view of the landscape.
The bottom line for Hall AI users
Hall AI's shutdown is frustrating, but the timing isn't terrible. The GEO tools market has matured significantly in the past 18 months, and the options available now are meaningfully better than what existed when Hall launched.
If you want a direct replacement with minimal friction, Otterly.AI gets you back to baseline quickly. If you want better data quality and slightly more depth, Peec AI is the step up. And if you're ready to stop watching your AI visibility and start improving it, Promptwatch is the platform built for that.
The AI search channel isn't going to get less important. The brands that figure out how to rank in ChatGPT and Perplexity now will have a meaningful head start over those still treating it as a monitoring exercise.
