FilingFirehose vs AlphaSense

AlphaSense is enterprise NLP search across filings, transcripts, news. FilingFirehose is a focused JSON API for SEC filings only — much cheaper, narrower, and self-serve.

When FilingFirehose is the right call

You want body-text-parsed 8-K items — including a flag for filings where the body language suggests a different item than what the filer reported. You're at the $29–$299/mo tier and don't need enterprise contracting.

When AlphaSense is the right call

You want a much broader form-type catalog beyond the 8-K / S-3 / 13D core, you're willing to pay enterprise pricing, and brand recognition matters for an internal tooling pitch.
