Key Takeaways
- Aiso is much cheaper to start: $19/mo for 50 prompts versus $95/mo for Promptwatch Essential. The catch is that Aiso covers only 3 AI models on every self-serve plan.
- Promptwatch includes every supported engine at every tier, plus 6,000 responses on the entry plan. Aiso's real edge is research data: Conversation Explorer is built on real multi-turn AI conversations.
- Promptwatch goes past tracking. It has content gap analysis, a Content Agent that publishes to WordPress, Webflow and Framer, an Action Board, and IP-verified AI crawler logs. Aiso is mostly a research and monitoring tool with a Crawlability Audit.
- The price gap narrows as you scale: $215 vs $245 at 150 prompts, $445 vs $579 at 350 prompts.
- Aiso gives unlimited users on every plan. Promptwatch caps seats at 1, 2 and 5 on the standard tiers, though agency plans include 10 seats.
- Aiso keeps API access for Enterprise only. Promptwatch includes API and MCP access from the $95 plan.
Overview
Promptwatch
Promptwatch is an end-to-end GEO and AI visibility platform. It tracks how your brand shows up in ChatGPT, Google AI Overviews, AI Mode, Gemini, Perplexity, Copilot, Claude and more, then helps you fix the gaps. The platform scrapes the real consumer interfaces of these tools, not just API outputs, which matters because user-facing answers often differ from API ones.
The pitch is action. Content gap analysis shows which prompts competitors win and you don't. The Content Agent writes and publishes articles, the Action Board turns data into a prioritized to-do list, and crawler logs and visitor analytics show whether AI systems read your pages and whether that traffic converts. It is rated 4.7/5 on G2 and used by 1,840+ brands and agencies, including Duolingo, Yelp, Typeform and Fireflies.
Aiso
Aiso is a newer AI search visibility tool with a distinct angle: conversations, not single prompts. Its Conversation Explorer is built on a panel of real multi-turn AI-human conversations, and Aiso claims a median 59% of what users say comes after the first prompt. That is vendor data, but the idea is sound. Buyers do ask follow-ups, and a keyword-style prompt list misses them.
It also offers fan-out discovery, GPT Trends, a Mention Tracker for mentions and cited sources, a Crawlability Audit, a Third-Party Source Mapper, and human approval workflows. Pricing starts at $19/mo. The trade-off is a 3-model cap on all self-serve tiers.

Head-to-head deep-dive
Research and prompt discovery
This is where Aiso is most interesting. Conversation Explorer shows real multi-turn conversations, so you can see the follow-up questions buyers ask after the first answer. Fan-outs and GPT Trends add a view of what the AI searches for behind the scenes.
Promptwatch has its own answer. Prompt Intelligence gives monthly prompt volumes, difficulty scores, citation rates, and query fan-outs showing the exact searches AI runs per response. Prompt Explorer suggests prompts from Search Console, People Also Ask and your own pages. It is more quantified, less conversational.
| Capability | Promptwatch | Aiso |
|---|---|---|
| Fan-out queries | Yes | Yes |
| Prompt volumes and difficulty | Yes | Not listed |
| Real multi-turn conversation panel | No | Yes |
| Suggestions from Search Console | Yes | Not listed |
Verdict: Aiso for conversation-level discovery. Promptwatch for volume and difficulty data you can prioritize with.
Model coverage
Promptwatch includes everything at every tier: ChatGPT, Google AI Overviews, AI Mode, Copilot, Perplexity, Gemini, Claude, DeepSeek, Mistral, Alexa and the coding agents Codex and Claude Code. Aiso's self-serve plans pick 3 models. If you care about ChatGPT, Perplexity and Gemini only, that is fine. If your buyers use AI Overviews or Copilot too, you will either swap models in and out or go to Enterprise.
Verdict: Promptwatch, clearly.
Turning data into action
Promptwatch's content gap analysis feeds the Content Agent, which plans, writes and publishes GEO-optimized articles on a schedule you control, with a review inbox if you want a human in the loop. Published pages are then tracked through crawls, citations and AI traffic, and underperformers come back as actions on the Action Board. Agent Chat lets you ask questions of your live data and build reports.
Aiso's route is lighter. The Crawlability Audit, Third-Party Source Mapper and human approval workflows point you at what to fix, and exports go to Google Docs or PDF. Its own schema experiment (paired sites with and without JSON-LD, roughly 30% easier retrieval) is a useful data point, though it is vendor-run. You do the writing and publishing yourself.
Verdict: Promptwatch, by a wide margin, if you want the tool to help ship the fix.
Technical visibility and crawler data
Promptwatch logs AI crawler hits (GPTBot, ClaudeBot, PerplexityBot and others) with IP verification, so spoofed bots are filtered out. You see which pages get read, which return errors, and the path from crawl to citation. Weekly site audits run 21 checks. For context, Promptwatch Data tracked IP-verified AI crawler requests from June to September 2026, and the mix of bots shifts quickly.
Aiso has a Crawlability Audit, which is a point-in-time check, not a log of actual bot behavior. It is not available on the Starter plan.
Verdict: Promptwatch.
Competitor tracking and reporting
Aiso hides competitor tracking on Starter, so the cheapest plan only tells you about your own brand. Pro adds multi-country tracking and PDF exports; Advanced adds Looker Studio, branded PDFs and a multi-client workspace.
Promptwatch includes competitor analysis, heatmaps, Share of Voice, sentiment and custom dashboards, with PDF and scheduled reports, white-label options on agency plans, and a Looker Studio connector from Professional.
Verdict: Promptwatch for depth. Aiso is adequate once you are on Pro or above.
Team and access
Aiso allows unlimited users on every plan, which is generous. Promptwatch limits seats on the standard tiers (1, 2, 5), and Business is sold via a demo. For a large internal team on a budget, Aiso is friendlier. Agencies on Promptwatch get 10 seats on every agency plan.
Verdict: Aiso for large teams on standard plans.
Pricing comparison
Pricing is from each vendor's pricing page. Confirm the current numbers at promptwatch.com/pricing and getaiso.com/pricing before buying. Annual billing is discounted on both (Aiso 15%; Promptwatch 12 months for the price of 10).
| Plan | Promptwatch | Aiso |
|---|---|---|
| Free | Explore: free, 10 prompts, ChatGPT only | None; 7-day trial |
| Entry | Essential $95/mo: 50 prompts, 6,000 responses, all models | Starter $19/mo: 50 prompts, 3 models |
| Mid | Professional $245/mo: 150 prompts, 18,000 responses | Pro $215/mo: 150 prompts, 3 models |
| Top self-serve | Business $579/mo: 350 prompts, 42,000 responses | Advanced $445/mo: 350 prompts, 3 models |
| Agencies | Kick-off $199, Growth $399, Scale $799 (unlimited projects) | Multi-client workspace on Advanced only |
| Enterprise | Custom: SSO, managed content workflows | Custom: unlimited prompts, all models, API, SSO |
At 50 prompts, Aiso's price is a fraction of Promptwatch's. But the unit of work differs. Promptwatch's entry plan includes all models and 6,000 responses, so you are buying broader coverage. Aiso's own per-pair framing (50 prompts x 3 models at $19) is about $0.13 per prompt-model pair. Whichever tool you pick, compare on what you will actually use: models, response volume, and whether you need content tools.

Final verdict
Promptwatch is the better platform for most teams that want AI search to produce revenue, because it covers every engine and helps you act on what it finds. Aiso is the better pick if budget is tight, 3 models are enough, and you value its conversation-level research. Start with Aiso's $19 plan to learn the space, but plan to outgrow it if you need content execution, crawler data or full model coverage.
