Practical tools for real problems
From the visual AI agent builder Amistio and our AI lab Lamplit Light to medical exam prep, citizenship tools, career resources, developer utilities, and compliance — we build practical software that makes a real difference.
Our Story
Why “Lamplit Labs”?
lamplit /ˈlamp·lɪt/
adjective — illuminated by the light of a lamp. A warm, focused glow that cuts through darkness and brings clarity to what matters.
We chose “Lamplit Labs” because it captures exactly how we work: shining a focused light on real problems, then building practical tools to solve them.
No hype, no complexity for its own sake — just clear, purposeful software that illuminates the path forward for our users.
Formerly known as bitesinbyte, we've grown from a side project into a lab that ships products used by thousands.
Lamplit Light · our AI lab
AI that runs where you are.
We build small, specialised models you host yourself - in a browser, on a laptop, on-prem, in your private cloud, inside your app or on the edge. Your data never leaves. The weights are yours.
small models · hosted by you · no data leaves
where it runs
The runtime changes, the model does not.
Sovereign means you hold the weights, control the hardware, and decide when models change, what they cost, and who reads traffic.
02
Laptop
Local sessions on hardware already in your hands.
03
On-prem / private cloud
Your servers, your network. The same exported model.
04
Inside your app
Embedded where your product already runs, with no round trip.
05
Edge / IoT
Small enough to ship close to the signal.
how a model is built
A high-level path from job to shipped runtime.
Five stages, one bar to clear. A model that fails its gate does not ship.
build pipeline
light-<purpose>-<version>01 / define
Define the job
A narrow purpose and a clear bar the model has to clear.
02 / verify
Gather verified knowledge
Ground the model in source material that can be checked.
03 / train
Train a specialist
A small model is trained for exactly this job and nothing else, so it stays small enough to run on your hardware.
04 / measure
Measure
Deterministic release gates and an independent judge panel decide what ships.
05 / ship
Compress and ship
Exported to ONNX and quantised, it loads straight into transformers.js.
the model family
One job per model. Every model yours to run.
- One clearly defined job per model, named
light-<purpose>-<version>. - Every release lists its purpose, base model, size, licence and gate result.
- Models that fit run in the browser; the rest run on hardware you control.
- Your prompts and data stay on the device or server you run the model on.
In development · public site coming to ai.lamplitlabs.com
Every model is measured before it ships. The release gates and the judge panel decide, and the numbers are published on the AI site — including the ones that fail.

Our Journey
From a side project to a lab
Six years of building useful things - and a clear view of where the light points next.
2020
bitesinbyte is born
What started as a side project: a place to learn in the open and ship small, useful software.
2020- 2024
2024
Leben in Deutschland goes live
A citizenship test app and website - completely free. Most prep apps drown learners in ads, which defeats the purpose of learning. So we built one without the noise.
2025
Kenntnistrainer & Fachsprachtrainer
AI-powered exam simulation for international doctors in Germany - structured cases, instant feedback, and real medical German.
2025- 2026
2026
Amistio MVP launches
Our visual AI agent builder goes live: agents that do real work, with versioning and approvals keeping humans in control.
2026
bitesinbyte becomes Lamplit Labs
A new name to match where we're headed - a lab that shines a focused light on real problems.
2026- 2026
2026
Lamplit Light: our AI lab
We start building small, specialised models you host yourself - one model per job, each measured before it ships. AI that runs where you are.
What's next
A lab in the truest sense
As our name promises, we're going deeper: with Lamplit Light we research how models are built, trained and measured - and ship that knowledge as models you can run where your data lives, alongside practical tools that put it to work for people.
Sovereign AI with Lamplit Light
Small models you own and run yourself - each built for one job, measured against release gates and an independent judge panel before it ships.
Tools for humans
Building focused products for real use cases that genuinely benefit people.
