Instabase vs Tennr (2026)
Both read documents nobody wants to read and one is built for a single industry, at 11.5 and 7 of 14.
Instabase is the general platform for extraction, validation, reasoning and action across unstructured documents. Tennr uses purpose built vision language models to read inbound faxes and documents, validate them against payer criteria and automate intake, eligibility, benefits investigation and prior authorization for referral based care. If your documents are healthcare referrals arriving by fax, Tennr's models were trained on exactly that and the general platform will need teaching.
Choose Instabase if
- Documented coverage is materially broader and your documents span many industries.
- Reasoning across document sets is the capability, not one workflow.
- You want a platform you can point at the next document problem too.
Choose Tennr if
- Healthcare referrals arriving by fax is precisely your problem.
- Validating against payer criteria at intake stops denials before they happen.
- Eligibility, benefits and prior authorization downstream is the workflow, not just extraction.
