Why people look beyond Semji.

Semji is a content platform for SEO and GEO. It detects opportunities, writes and optimizes content in your brand voice, plans the calendar and measures traffic, conversions and citations, and its Intelligence Hub tracks how visible your brand is in LLMs. 1

It is quote-based. Semji publishes no price list, because the scope varies with workspaces, markets and AI usage. Seats are part of the quote, onboarding is scoped, a customer success manager comes with the contract, and the six engines it tracks are not priced per model. 2

It also sells GEO services. A dedicated consultant audits the technical, popularity and content sides of your visibility, builds a prioritized plan, works on PR and social strategy to earn mentions and citations, and reports on how your positioning in AI answers changes. 3

Upthread is built for one source those answers lean on: Reddit. It ranks the threads that Google results and AI answers show your buyers, drafts two replies per thread that follow the subreddit's rules and disclose your connection, and keeps a record of each reply after you post it.

Who should choose which.

Who should choose Semji

  • You want one platform for SEO and GEO content, from finding opportunities to writing, planning and measuring ROI. 1
  • You need DeepSeek tracked alongside ChatGPT, Google AI Overviews, Gemini, Perplexity and Claude, in one contract with no charge per model. 2
  • You want GEO consultants alongside the software: audits, a prioritized plan, PR and social strategy, and a dedicated consultant. 3

Who should choose Upthread

  • You want to answer Reddit threads rather than produce more pages: a ranked list of threads and a reply drafted for each one.
  • You want a self-serve start: sign up with your website, see a ranked inbox within minutes, and pay a public monthly price.
  • You want the questions, objections and comparisons buyers raise on Reddit gathered in one place, to feed your content plan.

Switching from Semji.

Type in your website and Upthread drafts the brand profile, then suggests buyer questions, competitors, keywords and focus subreddits, each one editable. Carry your Semji prompts over as buyer questions and your brand voice into the profile, add a disclosure line, pick engines and a country, and the first runs start; a ranked inbox should appear within three minutes. The extension is optional.

What you bring across

  • Your strategic prompts. The ones a buyer would ask become Upthread buyer questions, checked in Google's AI answers and in ChatGPT, Perplexity, Gemini and Claude.
  • Your brand voice and facts. They go into Upthread's brand profile, so each draft sounds like you and sticks to what is true.
  • Your competitor set, with aliases, for share of voice in AI answers and to flag Reddit threads where a rival is recommended.

What works differently

  • Semji measures your citation and mention rates in LLMs to guide new content. Upthread looks at the Reddit threads those answers cite and drafts a reply for each one worth joining. 4
  • Semji is priced by quote after a demo. Upthread's plans are public, from $49 to $499 a month, with a 7-day trial that needs no card. 2
  • Semji's agents draft briefs and pages for your site, and nothing goes live unless someone asks. Upthread's drafts are Reddit replies, and you post the one you choose from your own account. 1
  • Semji tracks DeepSeek among its six engines. Upthread reads Google AI Overviews and AI Mode from live Google results twice a week, and ChatGPT, Perplexity, Gemini and Claude weekly by API. 2
