Contlo.ai vs ToolerBox (formerly H-supertools)

Contlo.ai is an all-in-one AI marketing platform. With a conversational UI, you can manage all your marketing needs through a single chat interface - powered by your brand’s own intelligence.

Here are a few of the many cool things you can do with Contlo AI:

1. Send Email and SMS campaigns via chat - Our AI assists you in end-to-end campaign management and A/B testing while you sit back and relax.
2. Create customer segments in plain English** - Adopt a brand new "what you type is what you get" approach to simplify audience management.
3. Get deep insights with just a prompt - Predict winning creatives, channels, and much more by understanding your audience like never before. No more clunky analytics tools.
4. Run ads and post on Social Media - Manage everything from designing creatives for multiple platforms to performance marketing in a single chat.
5. Write SEO-optimized blogs and marketing copies - Create long-form content and post it directly on your CMS.

ToolerBox is a free online marketing and productivity toolbox with 174 browser-based utilities for SEO, YouTube, writing, developers, networking, email, images, PDFs, and everyday calculations. The former H-supertools AI writer URL now redirects here, but the site has grown into a broad catalog rather than a single writing app. You can open most tools without creating an account, and many run entirely in your browser so inputs never leave your device.

Where standalone SaaS apps charge monthly for one job, ToolerBox bundles keyword research, PDF editing, JSON formatting, bulk email verification, QR codes, and AI helpers like an image-to-prompt generator into one free site. The trade-off is navigation: you pick from 12 categories and 174 tools instead of a guided workflow built around one task. Teams that need automation can use the documented REST API and MCP server with credit-based billing per endpoint.

Marketers, SEO specialists, content writers, and developers use ToolerBox for quick checks that do not justify another subscription. Common jobs include keyword volume lookups, on-page word counts, UTM link building, DNS lookups, and PDF splits or compressions. The web toolbox stays free; API access is optional for bulk jobs and integrations.
