Things we built at 2 AM. Try them. No email walls.
Every tool here runs free, in your browser. SynapseIN stores nothing and sets no tracking cookies; where a tool calls a public API (weather, geolocation), that provider sees your IP like any website does — full list in the privacy policy. Some are polished, some are honest experiments. That's what a lab is. — Manas
Fair use: free for business owners - check up to 3 different websites per day (your own site: unlimited re-checks). Agencies running many client domains: these tools are not a white-label workbench - here is what we offer agencies instead.
The Demand Forecast
Our biggest experiment gets its own page: live 7-day weather-demand forecasts for 14 trades — plumbers, HVAC, mechanics, roofers, fishing guides and more. Auto-detects your city, scores every day for your trade, and tells you what to prepare 48–72 hours early.
Ask SynapseIN
Type any question about SEO, AEO, GEO or your website. The machine answers instantly from everything we have published - sources linked under every answer. When it doesn't know, it honestly says so and hands you to a human.
The Accidental AI Lockout
We read the public robots.txt and llms.txt of 335 small-business websites across five industries. 1 in 13 with a robots.txt fully blocks a major AI crawler — most apparently by accident. Four sites block everything, including Google. Full method and dataset published.
Through Machine Eyes
Enter your website and see exactly what Google and AI engines read — your title, headline, schema, AI-crawler policy, llms.txt — next to an honest projection of the same machine view after the gaps are fixed. Optional emailed report; the on-screen version is complete without it.
The 2 AM Test
It's 2 AM. Something just went wrong in a stranger's life — a burst pipe, a toothache, a dead car. They search for exactly what you do. Answer eight honest questions and find out whether they'd reach you… or your competitor.
AI Visibility Scorecard
Ask the four AI engines about your business (buttons below open each one with the question ready). Then mark what you found, and generate a scorecard image you can save or post. Your data never leaves your browser.
Where did your business actually appear?
Surge Watch: the public scoreboard
Every week we log our weather-driven demand calls here before the weather happens. The following week, each one gets marked: hit, miss, or partial — with links so you can verify. No deleting, no quiet editing.
| City | Logged | The call (before the weather) | Target day | Result |
|---|---|---|---|---|
| No live calls yet this week. The engine logs new calls each Monday (UTC) where the forecast qualifies - never invented, never deleted. | ||||
Archive: founder-logged calls, July 2026 (pre-engine, kept for the record - never edited)
| Logged | Call | Verify by | Result |
|---|---|---|---|

One JSON state file in the server home directory · forecast + archive source: Open-Meteo (free, no key) · every mark carries its own evidence link · page rendered 14 Oct 2026, 5:53 pm UTC.
Scoreboard opened July 9, 2026. The weather leg of every call verifies itself: this page fetches the recorded weather for each window directly from Open-Meteo and marks the condition met or missed — no waiting for us to grade ourselves, and no way to quietly edit a miss. The demand leg stays yours to judge via the Google Trends links. Misses stay published. Since 29 Sep 2026 the calls themselves are generated and marked server-side by the Surge-Watch engine (fresh qualifying calls every Monday, marked from the weather archive with evidence links); the July founder-logged rows remain as the archive and keep their browser-side self-verifier.
The AI Answer Time Capsule
Once a month, we ask the same five questions to ChatGPT, Perplexity and Google AI — by hand, screenshots kept — and archive the answers, dated. Over time this becomes a public record of how AI recommendations shift. Nobody can rebuild this later; the past doesn't rerun.
The five fixed questions (locked, never changing):
How this capsule works — honestly: the five questions above are locked forever, and each has a one-tap button below that opens the engine with the prompt ready. Run them, screenshot, date it — you’ve made a capsule entry that nobody can backdate or fake later. Our own entries get published here as they’re recorded (no fixed schedule promised — recorded beats scheduled), and the archive rule below never changes.
Archive rule: entries are never edited after publication. If an engine's answer embarrasses us — including question 4 — it stays.
Steal Our Audit
This is the actual checklist we run on paying clients' websites. Do it yourself, free. If you get through all twenty and fix what you find, you honestly may not need us — and that's fine. The ones who read this and still call are our favourite clients anyway.
Find & trust (the human layer)
- Search your service + city in a private browser window. Are you on page one — and in the map results?
- Ask ChatGPT and Perplexity "best [your service] in [your city]". Are you in the answer at all?
- Can a stranger tell what you do, where, and for whom within ten seconds on your homepage?
- Is a price, price range, or "what affects price" explanation anywhere on the site?
- Is your phone number clickable on mobile — and visible without scrolling?
- Do your reviews tell stories, or just give stars? (Stories convert. Ask "what happened?", not "how many stars?")
Machine layer (Google & AI readability)
- Run your homepage through Google PageSpeed Insights. Mobile score below 60 means you're losing people before the page paints.
- Paste your URL into validator.schema.org. Any structured data at all? Organization? LocalBusiness? FAQ?
- Open yoursite.com/robots.txt — are GPTBot, ClaudeBot and PerplexityBot allowed, or accidentally blocked?
- Does yoursite.com/llms.txt exist? (Almost nobody's does. Ours does — that's the point.)
- Google "site:yoursite.com" — how many pages are indexed vs how many you actually want a buyer landing on?
- Does every important page answer a question a real customer asks — in the first two paragraphs?
- Check your Google Business Profile: exact category, services filled, real photos newer than a year?
- Are your name, address and phone IDENTICAL everywhere they appear online — down to the comma?
The uncomfortable ones
- Would YOU choose your business over the top three competitors, seeing only the websites?
- Is there one sentence on your site a stranger would remember tomorrow?
- Does your site prove a real human runs the business — face, name, story — or could it be anyone?
- If your best customer described why they trust you, is that reason written anywhere on the site?
- When did anyone last update the site? Would a visitor be able to tell?
- The 2 AM test above — did you actually take it, or just nod along?

The "AI-Readable Website" badge
Passed the machine-layer checks above — schema valid, AI crawlers allowed, answers extractable? Then claim the badge and put it on your site. It links to the checklist, so anyone can verify what it means. It's dated, because verifications age.
Checked against the SynapseIN Lab checklist · July 2026
Honesty clause: the badge is self-claimed against a public checklist — like a fitness plan, it works if you actually did it. Fake claims are visible to anyone who checks, which is rather the point of the checklist being public. Want it independently verified by us? That's part of every paid audit.
The Invisibility Counter
Every completed free audit increments this counter automatically on our own server — no hand-tallying, no inventing. The invisibility percentage gets published once the sample is big enough to mean something.

Questions people ask
Are the SynapseIN Lab tools really free?
Yes. Every tool in the Lab runs in your browser with no signup, no email wall and no tracking. They exist to demonstrate how SynapseIN thinks about visibility — if a tool is useful, the method behind the paid work probably is too.
What is the 2 AM Test?
An eight-question self-check that asks one thing: if a stranger with an emergency searched for your business at 2 AM, could they find you, trust you and contact you without friction? It scores your website the way a stressed customer experiences it.
What is the AI Answer Time Capsule?
A public monthly archive of what ChatGPT, Perplexity and Google AI actually answer for fixed business questions. Recorded by hand, dated, and never edited afterwards — so anyone can see how AI recommendations change over time.
How does the Surge Watch prediction scoreboard work?
Each week SynapseIN logs its weather-driven demand calls publicly before the weather happens, then marks every one as hit, miss or partial the following week, with verification links. Misses stay published. That is the point.
