Suparank is an AI visibility tool that runs your buyers' prompts through ChatGPT, Gemini, Claude and Google AI Overviews, then reports your mentions, citations, sentiment and share of voice against competitors.

It replaces the rank tracker in an AI-first search stack: instead of a keyword position, you see whether the answer a buyer actually read names you. Alongside visibility measurement it runs technical and GEO audits, connects your GA4 and Search Console data, and drafts content — all from one chat with a markdown artifacts library.

No rank tracking. Ask your first question free, no credit card needed.

Spreadcast is a marketing automation tool for developers who publish apps on the Apple App Store. Setup takes one input: the app’s App Store link. From then on, Spreadcast checks the public listing every day for events worth announcing, such as a new version release, a new five star review or a rating milestone.

When it finds one, it drafts a social media post about it. The image is built from the app’s own icon, screenshots and colors, with screenshots shown inside an iPhone frame, and a separate caption is written for each network. The post is then published to the connected accounts on many social media accounts you can connect.

Developers choose how much control to keep. Posts can wait for approval or publish on their own. A post that quotes a customer review always waits for approval, since Apple allows reviews in marketing only with the reviewer’s permission. Posts can also be written or edited by hand, and the developer’s own pictures or video can be uploaded and scheduled alongside the automatic ones.

Nothing is installed in the app and no access to the developer account is needed, because Spreadcast reads only public listing data. Google Play apps are not supported yet, and the tool makes still images, not video.

A free plan creates post drafts to download. Paid plans start at $29 a month and add automatic publishing. The Studio plan, at $79 a month, covers five apps and three team seats.

Most WordPress sites have posts that no other post links to. Readers and Google find posts by following links, so those posts get missed.

Silotree reads every post on your site and finds the ones with no link in from another article. For each one, it finds a sentence in your other posts that already mentions it and suggests the words to link. You see the sentence, the link text and where it leads, then approve the ones you like.

Approved links go into WordPress for you to apply. Silotree saves a revision first, checks that each link landed, and every batch can be undone in one click. Nothing is written until you say so, and links stay if you cancel.

It works with Gutenberg, the Classic Editor, Elementor, Divi, Beaver Builder, Bricks, Yoast, Rank Math, WPML and Polylang. Connect Search Console to see the clicks each link earns. You can also connect Silotree to Claude, ChatGPT, Cursor or VS Code and ask which posts need links.

Start with a free audit and a Silotree Score from 0 to 100. No account needed.
