AI search visibility audit: Lumo Notes (started 2026-10-10)

1. Scope

• Platforms run: none. I can't browse or query AI platforms here, so there are no AI answers, no scores and no presence rate yet.
• What I could check: the robots.txt and the home page description you pasted.
• Target markets: worldwide, in English and Portuguese. I suggest Portugal, UK and US as the test countries. Tell me if you want others.
• Run count: 3 runs per query per platform, each in a fresh session, logged out, with memory and personalization off.

2. Brief (what I have and what's missing)

3. Site readiness findings (from what you pasted)

P1: Key facts are not in the HTML (heuristic).

• The served HTML is <div id="root"></div> plus scripts, so price, features, location and audience exist only after JavaScript runs.
• Vendors don't all document whether their crawlers execute JavaScript. Confirm per vendor.
• A fetcher that doesn't run scripts would see no description at all. That leaves the AI to fill the gap from third-party pages, which could explain "a Notion plugin" and "free".
• This is a hypothesis, not a confirmed cause. I haven't seen the answers or their sources.
• Fix: server-render or prerender the home page, and add static pages for pricing, features, About and FAQ. These pages should state in plain sentences what Lumo Notes is, who it's for, that it works offline, that it's a standalone app and not a Notion plugin, and that it costs from 9 EUR/month. Date the pricing.
• Owner: engineering.
• Re-test: fetch the page with curl and check that the facts appear in the raw response.

P0 or P1: robots.txt blocks GPTBot and ClaudeBot (documented behavior, business choice).

• Both are named in the vendors' documentation as crawlers that collect training data. Confirm that against current docs, because the names and purposes change.
• Your User-agent: * group allows everything else. That includes OAI-SearchBot, ChatGPT-User, PerplexityBot and Google-Extended, plus any newer Anthropic user-triggered or search agents.
• So this is a partial block, not a total one. Whether it's unintentional is your call, so I'm not deciding it for you.
• Blocking training crawlers keeps your pages out of future model training. The cost is that models learn less from your own correct pages, so the wrong facts have fewer first-party sources to be corrected by.
• Allowing them doesn't guarantee better answers.
• Action: decide deliberately. If the block was intentional, keep it and make sure the search and fetch agents stay allowed.
• Also check: whether a CDN or firewall (Cloudflare, for example) blocks these agents regardless of robots.txt. I can't see that from here.

Fine: the sitemap is declared. Check that it lists the static pages above and has current dates.

Not yet checkable:

• Structured data (Organization and Product schema matching visible content)
• Portuguese pages and hreflang
• Consistency across profiles and directories
• Freshness of old pages

Low priority: llms.txt. No vendor has documented that it affects answers.

5. Run sheet (for you to fill in)

I'll score it once you've filled it in. I won't fill it in myself.

Platforms to cover: ChatGPT (with and without search), Claude (with and without search), Perplexity, Gemini, and Google AI Overviews.

What to paste: the full answer text for each run, especially the brand queries (1–6) and the cited URLs. The cited URLs let me trace where "Notion plugin" and "free" come from.

6. Provisional fix order (before any evidence)

1. P1: make the facts readable without JavaScript (see above).
2. P0, pending evidence: correct the wrong claims at their source. I can name the pages to fix once I see the cited URLs.
3. P1: decide the GPTBot and ClaudeBot policy and check for firewall blocks.
4. P2: add comparison pages ("Lumo Notes vs Obsidian/Joplin/Notion") and an FAQ. Keep them factual and dated.
5. P2: look for legitimate third-party coverage, such as honest reviews, directory listings and researcher communities. Which sources matter depends on what the answers cite.

Nothing here promises that AI assistants will start recommending you.

7. Questions for you

1. Is there a free trial or free tier, and what are the other plans?
2. Were the "Notion plugin" and "free" claims seen on specific platforms? If so, can you paste the answers and their sources?
3. Was blocking GPTBot and ClaudeBot intentional?
4. Do you have profiles or listings elsewhere (Product Hunt, Capterra, AlternativeTo, GitHub, LinkedIn)?
5. Which countries should I treat as primary?
