FREE TOOLS

Free tools for e-commerce brands

We build small, useful tools and give them away. No sign-up, no email-gate, no credit-card-up-front. If you find them helpful, tell another brand — that's all the payment we're looking for.

llms.txt Generator

Help AI understand your brand site.

  • — Audits existing files; generates if absent
  • — Curated H2 sections with descriptions on every link
  • — 3 free runs per IP per day

AI Shopping Readiness Check

How ready is your brand for the AI purchase channel?

Paste your brand's website — we run real queries on ChatGPT and Google AI Mode, sweep the open web for off-site signal, probe your site for AI-crawler access, and produce a structured 0–100 score across four pillars. With a verdict, three wins, and three actionable gaps.

  • — Four pillars: AI Behaviour, Signal, Technical, Transactability
  • — Real provider runs against ChatGPT & Google AI Mode
  • — Markets: US, UK, IN
  • — Refreshes every 28 days; full history per brand × market

Why these tools exist

Trust before transaction

Slingso sells a paid product. Before any brand pays us anything, they deserve to know how clearly we see the AI purchase channel — and how carefully we work. The free tools are how we show our work.

Sherlock is the consumer-facing version of what our agent does for brands every day: read the open web, weigh the evidence, and produce a verdict. If it can do that for one product, your brand can imagine what it does at scale.

llms.txt Generator is the simplest concrete step a brand can take toward AI discoverability. We built it because we kept getting asked the same question: "what's the one thing I should do?"

New tools land here as we build them. If there's something obvious we're missing, tell us.

Ready for more?

The free tools are the appetizer.

Slingso runs all of this — every day, on every product, across every AI assistant — and then acts on what it finds.
