expertOS vs Tegus
A subscription library of expert-call transcripts (now part of AlphaSense) with the option to commission your own.
A fair read on Tegus.
Tegus built a large, searchable library of expert-interview transcripts that investors subscribe to, plus the ability to commission custom calls. It’s now part of AlphaSense, deepening that combined transcript corpus.
Where Tegus is strong
- Deep, searchable library of past expert calls — fast context on a company or theme.
- Lower friction and more transparent than booking every call from scratch.
- Popular with public- and private-markets investors for diligence prep.
- Option to commission a custom call when the library falls short.
Where it leaves gaps
- A transcript library is past conversations — not a cited answer to your exact question today.
- Subscription access rather than paying per answer you’re missing.
- You still read, vet, and reconcile transcripts yourself.
- No research agent that checks the verified record before suggesting a call.
- No verified / inferred / unknown signalling on what you’re reading.
The answer — not just access.
Answer, then call
expertOS researches and answers from verified sources first, and only routes a paid call for the gaps that remain — so you don’t pay to read around your question.
Pay per missing answer
No library subscription. You pay only for the specific knowledge you lack, roughly 70% below legacy expert access.
Honest by default
Claim-level verified / inferred / unknown tagging tells you what’s grounded — instead of a raw transcript to interpret.
AI-moderated calls + synthesis
Commission a call and let an AI moderator run your guide, then synthesise themes and contrasts across every expert.
Every answer is tagged for how well it’s grounded.
Grounded in primary sources you can check.
A reasoned read — flagged so you know where to dig.
Not yet known — where a routed expert call earns its keep.
The same three-signal honesty runs through every expertOS answer — and into the call when one is needed.
Quick answers when Tegus comes up.
Tegus is a library of past calls. expertOS answers the question you have now — and books a new call only when it’s the cheapest way to close the gap.
