Why teams switch from OtterlyAI to GapStack
01
Gaps you can act on
GapStack turns every miss in search or AI into a Gap with the evidence attached, ranked by impact across search, AI, content, citations and technical issues. Otterly's Gap Analyzer mainly lists prompts where a rival is named and you are not.
02
Search and AI in one agency book
GapStack connects Search Console and GA4, ranks keywords daily, monitors backlinks weekly and shows the whole client book in Portfolio Today. Otterly stays on AI answers and GEO audits, so classic search still needs another tool.
03
Smarter cadence: Pulse plus Watch
GapStack runs a full weekly Pulse across every tracked prompt, then Daily Watch on the ones that matter, so overnight losses show up without burning a daily check on everything. Otterly meters the same daily cadence on every paid prompt.
04
Every engine on every plan
ChatGPT, Claude, Gemini, Perplexity, Grok and Muse are tracked from Solo upwards. No tier rationing, no engine picker.
05
Built for a client book
One portfolio across up to 30 sites, 20 seats, branded client reports and a daily digest of what changed.
06
Published prices, free trial
From £49 a month for one site, £109 for 10 sites. Start a 14-day free trial today, no sales call.

Where GapStack pulls ahead
01
Gaps plus Google, not AI reports alone
GapStack puts prioritised Gaps, daily rankings, Search Console, GA4 and Portfolio Today next to AI mentions and share of voice. Otterly stops at AI answer reports and GEO audits, so agencies still stitch search elsewhere.
02
Weekly full sweep, daily where it counts
GapStack's Pulse covers every tracked prompt each week and Daily Watch re-checks the priority set every morning. Otterly runs the same daily burn on every paid prompt, with no weekly versus daily split.
03
MCP that sees search and Gaps
GapStack ships MCP and API from Studio with Gaps, ranks and Google data in the same workspace, so agents fix what the portal already shows. Otterly's MCP starts on Standard and stays inside its AI reporting surface.
