Research that ships
CipherLabs is where CipherAI's researchers work on the hard problems behind our products — and publish what they learn.
What we work on
Each area feeds a product, so the questions we study come from real users.
Vietnamese legal & tax language
Finding, reading and explaining Vietnamese legal documents: a library collected from official sources, documents' effective dates and amendments, and answers that cite the article they rely on.
From research to product → eChat
Trustworthy & privacy-preserving AI
Answers that can be checked and measured: facts from reviewed data instead of model memory, systems that flag what they couldn't verify, honest evaluation, and personal data kept out of models.
From research to product → eChat
Agentic AI & data platforms
AI agents that use tools reliably — search, calculators, form drafting — on a mix of free and paid models, and the data pipelines that keep their knowledge current.

AI for nutrition & healthy living
Helping people eat better and move more, safely: understanding Vietnamese food descriptions, calorie figures from sourced data, and safety checks before any advice.

Research people can check
Facts from reviewed data
Rates, thresholds, deadlines and nutrition figures come from reviewed data with a source, never from a model's memory.
Measured, not assumed
Fixed test questions, blind comparisons and reviews of real anonymised questions tell us whether a change made answers better.
Privacy by design
Personal identifiers are masked before any model reads a document, and sensitive data goes only to providers that don't train on it.
From research to product
Every project feeds a CipherAI product, so the questions we study come from real users and the results reach them quickly.
Current projects
All projects →Document versions for Vietnamese law
Reading each legal document's effective dates and its relationships to other documents (replaces, repeals, amends, guides) so search knows what is in force on any date.
Skills we are looking for: Vietnamese NLP · Information retrieval · Legal informatics · Python
Tax answers built on reviewed figures
Calculators for income tax on salary, household-business tax and late-payment interest, driven by figures that a licensed tax agent reviews, so the assistant explains amounts instead of computing them itself.
Skills we are looking for: Tax law (Vietnam) · LLM tool use · Software testing
Measuring answer quality
Regression suites, blind comparisons with another assistant, and a nightly review of real anonymised questions, so improvements are measured rather than assumed.
Skills we are looking for: LLM evaluation · Statistics · Vietnamese NLP
Draft tax declarations in the official format
Turning a household business's calculated tax into a draft declaration laid out like the official form, and an export in the tax authority's XML format, with personal details kept on the user's device.
Skills we are looking for: XML schemas · Tax forms (Vietnam) · Front-end engineering
