Heidi vs Nabla (2026)
Heidi and Nabla both rose on clinician led adoption and both restructured commercially in 2026, so this comparison needs current quotes more than most: Heidi's February 2026 restructure centers a free tier with unlimited transcription and ten Pro Actions monthly, with Clinician at 150 dollars per user per month billed annually as the main paid tier and some tier prices conflicting across sources, while Nabla moved off its public tiers (historically a free tier and Pro near 119 dollars) toward demo and contract sales with aggregator listings conflicting on rates. Heidi's free unlimited transcription is the standout fact; beyond that, demo both and compare written quotes.
