* **Free Tier:** Limited (1,000 requests/month, then paid). * **Quality:** Good; focuses on news and general text, customizable. * **Underlying Tech:** Hybrid: rule-based + ML, not as deep as Google/MS/Amazon, but effective. * **Stability & Support:** **Moderate**; acquired by Quantexa in 2022, but still independent and active. * **Cons:** Not as big as cloud giants, so more risk in long-term.
