Sleepwalker is an AI-visibility and content-intelligence toolkit reachable natively through MCP, a REST API, a CLI and a web console, rather than a dashboard-only app. It runs prompts against ChatGPT, Perplexity, Grok and Gemini to show how a brand appears in AI answers, and separately scores and serializes any public page for AI-search readiness. Pricing is pure pay-as-you-go credits, €0.02 each, €5 minimum top-up (250 credits), with 10 free credits on signup and no credit card required, rather than a subscription tier. The GitHub repo behind it is maintained by a single developer, Anton Gorobets.

| Not for | buyers who want a proven independent-review track record, Claude/Copilot engine coverage, or a named, verifiable founding team |

## Verdict

Sleepwalker's real differentiator is how you reach it: MCP, a REST API and a CLI are the native interface, not an add-on bolted onto a dashboard, and pure pay-as-you-go credits (€0.02 each, €5 minimum) mean there's no forced monthly seat. A free, local `okf export` command that needs no account is a genuinely useful zero-cost utility on its own. But the product is thin on the trust side: no G2, Capterra, Trustpilot or Product Hunt listing exists anywhere, there's no published team or company page, and it tracks four engines (ChatGPT, Perplexity, Grok, Gemini), missing Claude and Copilot, which LLM Pulse and AIclicks both cover. It suits a developer or agent-building team that wants programmatic-first access and is comfortable vetting a very new, single-maintainer product; a buyer who wants a proven, GUI-first tool with a track record should look at GeoRankers or AthenaHQ instead.

## How it works

1. Create a free account and generate an API key, then script checks through the REST API or CLI, or connect Sleepwalker's MCP server so an agent like Claude can run actions directly inside a conversation.
2. An AI Visibility Run fires a chosen prompt at ChatGPT, Perplexity, Grok and Gemini and returns each engine's full response plus which domains were cited and whether the brand or named competitors were mentioned, at 1 credit per engine checked.
3. A Content Intelligence Run scores a public URL's topical coverage and freshness and flags gaps against what AI search currently rewards.
4. Run the free, local `okf export` command to convert any URL into clean, structured markdown with zero credits, account or API key required — reading back any stored run or report is also free.

## Who it's for

- Developers and AI-agent-building teams that want AI-visibility checks and content scoring reachable natively through MCP, a REST API or a CLI, without a monthly subscription.
- Teams that want a free, local, credential-free way to see exactly what an AI crawler would extract from a page before spending any money on a full visibility check.
- Budget-conscious teams that want cost to scale directly with usage — pure pay-as-you-go credits at €0.02 each — rather than a flat monthly seat.

## Strengths and weaknesses

- ✓ MCP, REST API and CLI are the native interface from the first signup, not a paid add-on bolted onto a dashboard, as on several competitors in this directory.
- ✓ Pure pay-as-you-go credits (€0.02 each, €5 minimum top-up) mean no forced monthly subscription, cost scales directly with usage.
- ✓ A free, local, credential-free CLI export (`okf export`) is genuinely useful on its own, independent of any paid Sleepwalker account.
- ✓ 10 free credits on signup, no credit card required, are enough for one full 4-engine AI Visibility Run.
- ✗ No independent reviews found anywhere: no G2, Capterra, Trustpilot or Product Hunt listing exists for sleepwalker.ai at verification time, and the GitHub repo backing it shows only 22 stars and 2 followers on its maintainer's profile.
- ✗ No team or company page is published on sleepwalker.ai itself — the only concretely identifiable person is GitHub repo maintainer Anton Gorobets (Netherlands); other public mentions of the product's launch were inconsistent about attribution and could not be independently confirmed, so treat single-founder identity as unverified.
- ✗ Narrower engine coverage than some rivals in this directory — tracks ChatGPT, Perplexity, Grok and Gemini but not Claude or Microsoft Copilot, both of which LLM Pulse and AIclicks cover.
- ✗ Credit-metered pricing makes ongoing cost harder to predict than a flat monthly plan, and the site publishes no calculator or estimated monthly cost for typical usage volumes.
- ⚠ The pricing page does not state whether unused credits expire.

## Key features

- **MCP + API + CLI native** — Visibility runs, content reports and page serialization are all reachable through an MCP server, a REST API and a terminal CLI, not bolted onto a web dashboard as an afterthought.
- **Free local OKF export** — `sleepwalker okf export` converts any public URL into structured markdown locally, with zero credits, account or API key required.
- **Multi-engine AI Visibility Run** — Fires one prompt at ChatGPT, Perplexity, Grok and Gemini in a single run and reports citations, brand mentions and competitor mentions per engine.
- **Content Intelligence scoring** — Scores a page's topical coverage and freshness and stores the full report in the console, separate from the visibility-check workflow.
- **Pay-as-you-go credits, no subscription** — €0.02 per credit with a €5 minimum top-up and no recurring plan, cost scales with actual usage rather than a flat monthly seat.

## Use cases

- **Agent-triggered visibility check** — A developer wires Sleepwalker's MCP server into Claude so an agent can check brand visibility on demand mid-conversation, without opening a separate dashboard.
- **CI-scripted brand monitoring** — A team scripts a periodic `sleepwalker visibility run` call into an existing CI or cron job to log ChatGPT/Perplexity/Grok/Gemini mentions alongside its other automated reports.
- **Zero-cost content check before publishing** — A writer runs the free local `okf export` on a draft URL to see the exact structured content an AI crawler would extract, before spending any credits on a full Content Intelligence score.
