How it works
Enter a handle. We instantly confirm the account exists and show you what we'll analyze before you pay anything.
AI reads every post. We pull their full history and extract each investment call — the ticker, direction, and how convinced they sounded.
Every call is backtested. We score each pick against real prices and against the stock's own sector — so a call only "wins" if it truly beat the market.
You get a verdict. A clear answer to "should I follow this account?", with the numbers behind it. Sent to your inbox when ready.
Where your money goes — run at cost, not for profit
XAnalytics is run at cost, not for profit. Here's exactly what one analysis costs us — using a 10,000-post account ($20) as the example:
| 1 · Fetch the posts Pull the account's post history (~10,000 posts). |
~$1.20 |
| 2 · Read & score every post Every post goes to Anthropic's Claude Sonnet 4.6 with our ~10,487-token analysis prompt — cached (re-reads bill ~90% off) and run via the Batch API (another 50% off). Most posts aren't calls, so the answer is a short JSON. ≈ 10,000 posts × ( prompt 10,487 tok × $0.15/M + post ~100 tok × $1.50/M + answer ~40 tok × $7.50/M ) = $15.73 + $1.50 + $3.00 ≈ $20.2 the post is the tweet plus the thread/quote context we feed in; the answer is short JSON — a tiny {relevant:false} for most posts, the full call (ticker, direction, conviction) for the rest |
~$20.2 |
| 3 · Double-check every short call Bearish takes are the easiest to misread, so a second Claude Sonnet 4.6 pass re-reads each one and drops the ones that aren't real short bets (a stock ranked below a favourite, a position being sold, a hedge) — only genuine shorts get scored. |
~$0.23 |
| 4 · Resolve each ticker A third Claude Sonnet 4.6 pass pins down exactly which security each call refers to. |
~$0.08 |
| 5 · Backtest vs. the market Historical prices from Yahoo Finance. |

| Compute total (our budget for an account this size) | ~$21.7 |
These are the amounts we budget for an account this size — most runs land a little under, though unusually long posts can push a bit over. On top of compute: card processing and a small share of servers, storage & email. The $20 fee covers all of it with no profit — any small surplus goes back into keeping every report free to browse. Smaller and larger accounts are priced proportionally (by post count). Claude Sonnet 4.6 batch rate: ~$1.50 input · $0.15 cached-read · $7.50 output per million tokens.
