Start with a business goal

Connect tools into a useful workflow

Choose the job you need to do. Use free tools first, then open account features if they help. No registration is needed to start, and no next step runs automatically.

Keep your website ready for buyers

Find public website and email configuration issues before choosing what to fix.

  1. Website Audit

    Get a combined report of access, SEO, performance and technology evidence.

  2. Email Health Checker

    Check business email DNS records and distinguish errors from missing evidence.

Sign in and configure a site. Advanced crawls require the appropriate plan and permissions and must be started explicitly.

Turn an inquiry into a quotable request

Understand the buyer, fill specification gaps, check costs, then prepare a follow-up.

  1. AI Inquiry Analysis

    Extract buyer needs and value signals without inventing missing facts.

  2. AI Product Specification Review

    List missing specifications, quantities and commercial terms for a quote.

  3. Landed cost & export quote calculator

    Calculate a quote using your own cost, duty and tax assumptions.

  4. AI Customer Follow-Up Draft

    Prepare a follow-up draft for human review; no email is sent automatically.

An account and the appropriate company permissions are required. Opening this page does not import or send customer information.

Prepare product materials buyers can use

Refine images and PDFs, then share through short links, QR codes and email signatures.

  1. Online Photo Editor

    Crop, adjust and export clear product images.

  2. Online PDF toolkit

    Convert, edit or compress a PDF, then check its content and readability.

  3. URL shortener

    Create a short link and QR code for public resources; check the destination and expiry.

  4. Email signature generator

    Create an email signature with product catalog and contact links.

These editing and export tools remain free. Choose business automation and monitoring only if you need them.

Build a brand buyers remember

Create a consistent visual identity, then find brand information missing from AI answers.

  1. AI Logo Generator

    Generate and review logo concepts; check trademarks before commercial use.

  2. Web Color Palette Tool

    Choose a website palette and check text contrast.

  3. GEO Brand Audit

    Review this Gemini answer sample and traceable brand evidence.

Scheduled reports need an active PRO / MAX entitlement and explicit activation. Opening the page starts no monitoring or notifications.

Check purchasing assumptions with engineering tools

Compare dimensions, material use and inventory assumptions before engineering approval.

  1. Hydraulic hose sizing & flow velocity calculator

    Compare hose bores using flow rate and an allowed fluid velocity.

  2. 1D Stock Cutting Optimizer

    Compare stock cutting plans, offcuts and real manufacturing constraints.

  3. EOQ & Tiered Volume Discount Optimizer

    Estimate an economic order quantity using demand and ordering and holding costs.

Engineering calculations remain free and depend on your inputs. Business monitoring and automation are optional.

This is a checklist you mark yourself, not a test pass rate or an automatic completion record.

AI steps have shared usage limits and human verification. They run only when you submit, and do not automatically receive inputs or reports from previous steps.

How to use these tools together?

What is the difference between Tool Groups and Comprehensive Audit?

Website diagnostics now use one entry: submit one URL to review HTTP, DNS, SEO, Discover, performance, crawlers and technology in one report. Failed, disabled and unavailable modules are identified separately. Original URLs remain available for old links; toolbox searches and favorites open the combined report. Other tasks keep their independent tools.

Do I need to sign up to use these tools?

No. Open a page and use it. Register a company account only when you need ongoing website monitoring, inquiry management or batch processing.

Are these tools free?

Local processing and single-run checks for public sites are free to try. Certain AI and query services are subject to quota or CAPTCHA limits. Background site audits and advanced tasks are available according to your current plan and permissions; external services are charged per their respective platform terms.

Bookmark Will my inputs be saved or synced to my account?

Bookmark Only tool identifiers are saved in your current browser. Inquiries, text, images, or check results are not saved or automatically synced to your account. Tools marked for local processing run in your browser; website queries and user-initiated AI analyses follow the instructions on their respective pages.

Are my files and data uploaded?

Image, PDF, JSON and text tools run locally in your browser and upload nothing. Website checks visit the public URL you enter; AI tools send your input to the model only after you click submit. Every tool page states where processing happens.
