The free tier is almost certainly enough.
Free Tier
Ambient transcription and note generation — the core value proposition. Basic EHR integration (EMIS/SystmOne). Sufficient recording capacity for typical trainee consultation volumes. No credit card required.
Pro Tier
Unlimited transcription and features. "Ask Heidi" clinical decision support — AI-powered guideline surfacing during or after consultations. Advanced note templates and customisation. Priority support. Pricing approximately $150/month (verify current UK pricing).
For GP Trainees
Trainee consultation volume is typically lower than established GPs — free tier monthly limits are rarely hit. The main Pro feature that might tempt trainees is "Ask Heidi" CDS. But Ask iatroX provides equivalent guideline-grounded clinical Q&A with NICE/CKS/BNF citations — for free.
$150/month is significant on a trainee salary and unlikely to be study-budget claimable. The cost-benefit does not favour Pro for most trainees.
Recommendation
Start with the free tier. Use it for 1-2 months. If you consistently hit recording limits or need features the free tier lacks, evaluate Pro. For clinical decision support, use iatroX Ask instead of paying for Heidi Pro — same function, zero cost.
Where iatroX Fits
Use Heidi free for scribing. Use iatroX for clinical Q&A. The combination provides ambient documentation plus guideline-grounded decision support at zero total cost.
