Jacobian vs Rad AI
Updated October 16, 2026
Radiology groups modernizing how reports get written often compare Jacobian and Rad AI. Jacobian joins speech recognition, guideline-based templates, and AI drafting in one reporting product, while Rad AI focuses on AI that writes impressions and report text for radiologists to edit. Whether dictation or AI drafting comes first sets the direction.
Our analysts compared Jacobian and Rad AI on dictation, structured reporting, AI drafting, turnaround impact, and deployment, using the HIR review of each company and each vendor's news pages. In the following sections, we compare them in one table, describe the group each fits, and list each company's news this year.

| Deal-breaker | No informatics owner. | No radiology IT owner for changes to reporting. |
| Pricing clarity score | 7.2 | 7.3 |
| HIR overall score | 7.8, Recommend. | 7.7, Recommend. |
| Best for | Radiology groups and health systems that want speech recognition and structured reporting from one vendor. | Radiology groups that track report turnaround and how consistent impressions and follow-up wording are. |
| Not a fit for | Buyers who want an AI impression generator first and dictation second. | Groups unwilling to keep radiologists reviewing AI-drafted text. |
Which fits which buyer
Decide which tool your radiologists will touch on every study.
Choose Jacobian if
- You need speech recognition and structured templates from one vendor.
- Guideline prompts inside the report appeal to you.
- Pediatric or subspecialty reporting is part of your work.
Choose Rad AI if
- AI-drafted impressions are the main goal.
- You track turnaround and consistency of follow-up wording.
- Your radiologists will review AI text on every case.
Verdict
The scores are nearly even. Jacobian fits groups that want one reporting platform, and Rad AI fits groups focused on AI impressions.
Many groups pair a dictation platform with an AI drafting tool.
Where the two tools are headed in 2027 and beyond
Jacobian: Jacobian expanded its pediatric imaging work with SickKids in Toronto on June 10, 2026.
Rad AI: Rad AI announced on June 10, 2026 that Yale New Haven Health was replacing older radiology systems with its tools.

Methodology
Each row comes from the HIR reviews of Jacobian and Rad AI, scored under the HIR method, and from each vendor's public pricing where it exists. Any published price for Jacobian or Rad AI was checked on that vendor's own site on October 16, 2026.
A green check marks a clear edge for Jacobian or Rad AI only where their review scores differ by at least 0.3 points or the two reviews show a plain difference. Rows with nothing published for either Jacobian or Rad AI are left out, and time to full value for each adds up the rollout stages in its review.
