About
SentiSense
Market intelligence you can access from an API, an AI agent, or our app. Sentiment, filings, flows, and prices from one data graph, priced for individual traders and builders.
Why this exists
The dots are scattered. We keep them in one place.
Prices sit in one vendor, filings in another, and the social signal that moves a stock before the news does is spread across a dozen feeds. The AI tools people now use to research a stock can reason well, but only over what they are given, and most of what they are given is stale.
SentiSense collects those streams continuously, scores them, and keeps them in a single graph that every surface reads from. Ask in the app, call the API, or hand it to your agent through the MCP connector or a skill. Same numbers, same freshness, whichever door you use.

By the numbers
What's under the hood.
Every figure links to the page that backs it. Document counts as of September 2026.
How it's built
Built to be trusted by a program, not just read by a person.
01
One source
Every surface in the app is the same API surface developers and agents call. If a number is wrong, it is wrong everywhere, which is why we work hard to make it right once.
02
Computed ahead of time
Story clustering, sentiment scoring, filings parsing, and report generation run in the background on a schedule. You get the result, not a spinner.
03
Honest about freshness
Prices are delayed 15 minutes, never sold as live; scores and signals come from the latest analytical batch. Every response says which.
04
Made for agents
Read-only tools, stable ids, documented limits, and a free key with no card, so an agent can start calling in a minute and a builder can ship on it.
Who we are
SentiSense is built by SentiSense Labs LLC, a small independent team of engineers from tech companies. We sell the data and the tools; we do not sell order flow, advertising against your research, or your data. Everything here is for research and education, not investment advice.
Two doors in
Use the app to research and track. Use the API to build it into your own workflow. Same data graph, different surface.
