Big questions.
Visible uncertainty.

Healthspan Lab is Kira Labs' public longevity and healthspan research prototype, being developed as an open-source platform. A user can start with a plain-language goal such as improving memory, sleep, mobility, cardiovascular health, or understanding biological aging. The current Version 2 code searches live PubMed / NCBI records and the ClinicalTrials.gov API, then organizes retrieved material into separate research lanes.

Results can be separated into peer-reviewed research, devices and neurostimulation, medications being studied, research-backed market and wellness options, and clinical trials that may be recruiting. Evidence from cells, animals, observational human studies, human interventions, and evidence reviews remains visibly distinguished so preliminary findings are not presented as established conclusions.

Users can create separate individual or household profiles with goals, interests, age, and general location. They can also optionally add recent medical PDFs or photos. Extracted information must be reviewed and confirmed before it can influence research relevance, and each household member's information stays separate.

Current Version 2 boundary: live source search, Healthspan Chat, local household profiles, profile-aware ranking, watchlists, a research graph, reviewed PDF/photo intake, and conservative product-category discovery are implemented in the public prototype. Encryption, deeper structured trial-eligibility parsing, pagination beyond the first retrieved set, browser integration tests, and packaged deployment remain unfinished. The public repository can be run locally with a local HTTP server; there is not yet a packaged desktop download.

Source status: the repository is public and is being developed toward open-source release. An explicit repository license is still pending, so this page does not claim reuse rights yet.

Kira World explores what happens when an AI identity is allowed to continue instead of resetting every session: reviewed memory, relationships, voice, personal spaces, and eventually richer embodiment.

Digital Twin work belongs to this Kira World research direction, not to Healthspan Lab. The questions include how a synthetic counterpart can be useful while a person is alive, how memories should be handled, and what continuity means when biological and digital lives are distinct.

Working now — Synthetic Robert / Digital Twin prototype: KiraWorld has a bounded local conversation route for a distinct Synthetic Robert. Current tests support text plus an approved self-voice path, and the memory-grounding code can select owner-authorized, query-relevant Robert records while preserving corrections, source attribution, audience/publication scope, and uncertainty. The route is explicitly distinct from biological Robert. Current activation does not claim a 3D body, world presence, life-loop activation, microphone, or webcam.
