SeeCost - All your LLM costs:OpenAI, Anthropic, Gemini — on one screen

Hi Product Hunt! SeeCost tracks OpenAI, Anthropic, and Gemini costs with zero API key setup. Just install our OSS SDK and run one init command to capture your spend automatically. OSS Tracker: https://github.com/ronpaou/seeco... ``` npm install @seecost/tracker npx @seecost/tracker init nextjs ``` We never store keys or prompt content—only usage metadata. Sign up free with GitHub.

tracked my time for a week. I spent 6 hours just copying, pasting, and formatting blog posts. 💀

AI made "writing" fast, but the publishing pipeline is still completely broken.

My workflow used to be:

  1. Prompt ChatGPT

  2. Copy the output

  3. Open WordPress/CMS

  4. Fix H2/H3 tags manually (the worst part)

  5. Add meta tags and hit publish.

I got so fed up with this brain-dead process that I built a script to bypass it entirely. Now, I just drop a reference URL, and it automatically handles the SEO writing, formatting, and API publishing to the CMS.

Widify - Auto-pilot SEO blog for developers. Just paste your URL.

I built Widify because I hate writing marketing copy when I could be coding. Paste your URL, and it learns your product to auto-generate and publish SEO articles straight to your WordPress or GitHub (Next.js/Astro). A true set-and-forget blog
