Applied research
A research lab in Sarajevo.
The first self-sustaining research lab in Bosnia. We build software of our own, and it pays for the research.
Canto, Tonic, and Orlo.
A recorder that turns every conversation into a searchable note, a coach that scores every call, and an assistant that answers from your own documents.


Every conversation, recorded and remembered.
Canto records on your phone, transcribes and titles each note on its own, and lets you ask questions across everything you have said.
- Records and transcribes
- Titles and files itself
- Ask across your notes
Every call, scored and coached.
Tonic scores every conversation against the quality criteria you set, tracks the numbers that matter, and tells each agent what to work on next.
- Real-time scoring
- Your own criteria
- Clear next steps
Annual plans can be refunded pro-rata within 30 days of renewal.1 After that window, the remaining balance converts to account credit for the next cycle. Refunds return to the original payment method within 5–7 business days.2
Provably the best knowledgebase in the world.
Orlo answers from only your own documents, every answer cites its source, and it tops the retrieval-accuracy benchmarks we run against it. Change a document and the answer changes with it.
- Under 10 seconds
- Stays in sync with your docs
- Every answer cites a source
A lab that pays its own way.
Tessa Labs is the first self-sustaining research lab in Bosnia. The products we sell fund the research we care about, so we answer to the work, not to grants. We pick our fields on purpose, and we build the proof here at home.
Self-sustaining
Our products pay for our research. No grants, no waiting for permission.
Language and voice
Our first field. The languages spoken here are overlooked, and we saw room to do better. Canto and Tonic came of it.
Knowledgebase systems
Our second field, chosen for expertise. Orlo is the proof.
Let's talk.
Tell us what you are working on. We read everything that comes in.
