Hall vs Otterly.AI: Free Tier vs Cheapest Broad Coverage
Hall vs Otterly.AI compared on free tiers, engine coverage, citation context, crawler analytics and content audits for small teams.
Hall and Otterly.AI are the two tools most teams try first, and the comparison is unusually close. Both cover a broad engine set cheaply. Hall has a genuinely usable free tier and crawler analytics; Otterly has a content audit and a lower paid entry point.
Disclosure: we build Kitbase, a competing tool, mentioned once at the end.
The short version
Start with Hall if you want to prove the channel matters before spending anything, or you want crawler data alongside answers.
Choose Otterly.AI if you want guidance on what to fix, or you’re an agency running many small accounts on a predictable low cost.
Free tier
Hall’s free tier is the strongest in the category and it isn’t a demo. It stores history, covers around eight surfaces, and includes server-side AI agent analytics.
Otterly offers a free trial rather than a free tier.
For a team that hasn’t yet justified GEO spend internally, that difference decides it. You can run Hall for a quarter, build a real trend, and go to your budget conversation with data rather than a hypothesis.
Hall wins, clearly.
Engine coverage
Hall covers around eight surfaces including ChatGPT, Gemini, Perplexity, Claude, Copilot, DeepSeek and both Google AI surfaces.
Otterly covers ChatGPT, Perplexity, Google AI Overviews and Copilot at base, with Gemini and AI Mode as add-ons.
Hall’s base coverage is broader, and includes Claude, which Otterly’s base tier doesn’t. Confirm both directly, since coverage changes frequently.
Hall wins.
Crawler analytics
Hall includes server-side AI agent analytics, tracking crawlers like GPTBot and OAI-SearchBot. Otterly doesn’t cover the crawler side.
This is more consequential than it looks for a team at this budget level. If your presence rate is low, the two candidate explanations are that your content isn’t good enough or that the engines never fetched it. Without crawler data you’ll spend months on the first assumption when the second is often true and much cheaper to fix.
Hall wins, and it’s the strongest argument for it beyond the free tier.
Citation context versus content audit
The two tools answer “what do I do now” differently.
Hall shows the conversation context behind each citation rather than the bare URL, so you can see how an engine characterised you and what it drew on. That’s diagnostic material.
Otterly runs a GEO content audit checking crawlability and citation potential, and flags what to improve. That’s prescriptive material.
Which helps more depends on your team. A team that can read data prefers context. A team that wants a task list prefers the audit.
A genuine split.
Side by side
| Hall | Otterly.AI | |
|---|---|---|

| Base engine coverage | ~8 surfaces incl. Claude | 4, more as add-ons |
| AI crawler / agent analytics | Yes | No |
| Citation context | Yes | No |
| GEO content audit | No | Yes |
| Prompt research | Yes | Yes |
| Geographic performance | Yes | Yes |
| Paid entry price | Mid-market jump | Entry-level |
Which to choose
Start with Hall’s free tier regardless. There’s no cost and it answers the question that should come first: does anyone in your category get recommended by AI, and are you among them?
After a quarter you’ll know which tool you need. If the answer is “we’re absent and our pages aren’t being crawled,” Hall’s crawler data is already telling you the problem and you’d stay. If the answer is “we’re crawled and still not cited,” that’s a content problem and Otterly’s audit plus its cheaper paid tier is a reasonable next step.
Hall’s paid tiers jump to mid-market pricing, which is where Otterly becomes the better value for teams that need continuous tracking without crawler data. That’s the real trade between them: Otterly is cheaper to run continuously, Hall is better at explaining what you find.
Neither goes deep on citation-level detail like separating mentions from citations or tagging cited sources by type, which is where mid-market and dedicated tools differentiate. Our AI visibility metrics guide covers what those distinctions buy you.
Kitbase covers both halves with verified crawler identity, at a price above both and tracking one engine on its cheapest plan. Covered in Kitbase vs Hall and Kitbase vs Otterly.
