Score and summarize earnings calls in plain English for retail investors.

In short: an AI-agent-run business you oversee about an hour a week. Tools cost $30–$175/mo, agent setup is advanced, and our estimate is 300 subscribers × $12 = $3,600/mo.

How it makes money: Charge retail investors $12/mo for scored, plain-English summaries of every earnings call.

Agent setup: Advanced · Needs custom code (Cursor) and hosting you maintain. How we rate this

Where this came from (Reddit)

Retail investors don’t have time to read hour-long earnings calls, and the useful signal hides in the unscripted Q&A.

The threads (in our words)

Reddit blocks automated reads, so we couldn’t record upvote or comment counts. The business below is our own design inspired by these threads.

Who it’s for

Retail investors and finance newsletter writers.

Adapt it to your industry

  • Start with one niche or customer type, then expand.
  • Ask your first 10 customers what they would pay before you build more.
  • Keep a human check on anything sent in a customer’s name.

Step by step

  1. Pick a coverage list (for example the S&P 500) and a licensed transcript source.
  2. Have an agent summarize each call within hours: guidance, margins, surprises and dodged questions.
  3. Score each quarter with a rubric you publish, so readers can check it.
  4. Keep past quarters free as SEO pages and sell alerts and watchlists as Pro.
  5. Post one chart or takeaway a day on X with Buffer.
  6. Monitor transcript freshness and errors daily.

Ready-to-copy prompt

Here is an earnings call transcript [paste]. Summarize guidance, margins and risks in 6 bullets, list the 3 analyst questions management answered least directly, and quote nothing longer than one sentence.

  7. Monitoring and schedule: Grok Bot (agent + scheduled routines) (opens in new tab) (Included with The X Subscription Premium $30/mo (Super $100/mo for more usage; Plus $8 does not include Grok Bot)). Grok Bot scheduled routines run each day: send, check for failures, alert you if something breaks.

What they did

Agents read every earnings call transcript, score the quarter on a published rubric and flag what changed in the analyst Q&A. We designed this business from real Reddit threads; it is an idea for you to build, not a description of the posters’ businesses.
