XAnalyticsDo they actually
beat the market?
Pick any X account that posts stock calls. We backtest everything they've said and show you whether their picks really outperformed — not just whether they went up.

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 full post history (~10,000 posts). |
~$0.64 |
| 2 · Read & score every post Every post goes to Anthropic's Claude Sonnet 4.6 with our ~8,200-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 8,200 tok × $0.15/M + answer ~60 tok × $7.50/M ) = $12.30 + $4.50 ≈ $16.8 the answer is short JSON — a tiny {relevant:false} for most posts, the full call (ticker, direction, conviction) for the rest; we budget ~60 tokens a post |
~$16.8 |
| 3 · Resolve each ticker A second Claude Sonnet 4.6 pass pins down exactly which security each call refers to. |
~$0.50 |
| 4 · Backtest vs. the market Historical prices from Yahoo Finance. |

| Compute total (our budget for an account this size) | ~$18.00 |
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 (~$0.88 on a $20 charge) 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.
