Scanned letters and shorthand
Referrals arrive as scans, photos and templated letters full of clinical abbreviations. Generic document tools misread them unless they are tuned and tested on real examples.
AI by industry · Healthcare
We build the AI inside clinical admin and health-tech products: document models that read referrals and letters, language models that summarise and draft, and image models that highlight findings — each tested on your own data and reviewed by the clinician who owns the decision.
Why health AI stalls
Clinical text is full of abbreviations, scanned letters and free-text notes. The hard work is making AI reliable on that material, and being clear about where its job ends.
Where AI helps clinical teams most
The safest returns are in the admin around care, and in preparing information for a clinician:
Referrals arrive as scans, photos and templated letters full of clinical abbreviations. Generic document tools misread them unless they are tuned and tested on real examples.
A summary that leaves out a symptom, or a priority suggestion that sounds final, can shape care. Where the AI stops and the clinician starts has to be designed, not assumed.
Health data needs a lawful basis, minimisation and careful hosting. Sending full records to a model “to see what it does” is how pilots get stopped by information governance.
A model tested on a clean public dataset can behave differently on your patients, scanners and letter templates. Without local evaluation, nobody knows how it really performs.
What we build
Every capability ships with an evaluation set drawn from your own records, a review step for the responsible clinician or administrator, and logs your IG lead can inspect.
Document and language models that read referrals, discharge summaries and results letters, returning patient details, reasons and actions linked to the source text.
Summaries of long histories and care records before a consultation or case review, with each statement traceable to the note it came from.
Computer vision models that highlight possible findings on X-rays, photos or scans for a clinician to review — the approach behind our dental imaging work.
Speech-to-text and language models that turn a recorded consultation into a draft note or letter, which the clinician edits and signs before it enters the record.
Suggested SNOMED CT or ICD-10 codes from notes and letters, with the supporting text highlighted, for clinical coders to accept or change.
Classify incoming emails, forms and messages — appointment changes, prescription queries, results questions — and route each to the right queue with a suggested reply.
How we work
The same seven stages as all our work, with clinical safety and information governance inside each: a written intended use, evaluation on your own data, and clinician review on anything that touches care.
We write down the intended use in plain words — what the AI does, for whom and what it must never do — and measure the admin task as it runs today.
An intended-use statement and baseline
We choose the technique and hosting, agree what data may be used and how it is minimised, and flag early whether the tool could be a medical device so you can take advice.
Pilot scope, data plan and regulatory flags
Review screens that show the source text beside every extracted field or summary line, clear labels on AI-drafted content, and quick ways for staff to correct it.
Review design and data-flow map
We build against a de-identified sample of your own records, with your clinicians labelling the examples that become the evaluation set.
A pilot on de-identified data
Accuracy, omission and hallucination checks by document type and patient group, plus hazard testing with your clinical safety lead on what happens when the AI is wrong.
Evaluation results and hazard input
A limited rollout with one team, AI output clearly labelled, every correction captured as feedback, and a rollback plan agreed in advance.
A monitored single-team launch
Monitoring of correction rates and failures, re-testing when templates, scanners or models change, and extension to the next team only when the results hold.
Monitoring and a scale-up plan

Safeguards
We are a software development company, not a clinical safety body or regulator. Your clinical safety officer, DPO and IG lead set the requirements and sign off; we build to them and supply the technical evidence.
Use cases
Tasks where AI reads, drafts or sorts, and a named person checks the result before it affects a patient.
Check each incoming referral against the service’s acceptance criteria and list missing tests, forms or details, so the team can request them before the patient waits.
Pull medication changes, follow-up actions and responsible clinicians out of discharge summaries into a task list for community or practice staff.
A one-page summary of recent letters, results and medications before a review, with each line linked to its source so the clinician can check it quickly.
Highlight possible findings on dental X-rays or clinical photos for the dentist or clinician to accept or dismiss — never a diagnosis on its own.
Sort patient messages and online forms by topic, send anything that mentions symptoms to clinical staff first, and draft routine replies for staff to send.
Semantic search across guidelines, protocols and internal procedures inside your product, returning cited passages rather than generated advice.

All case studiesWhy Techsleight
No inflated numbers — just how we run projects, and what you can hold us to.
We ask what the software is for before we estimate it — and we will tell you when something should not be built, or should be bought instead.
LLM features, retrieval and automation built with evaluation, guardrails and cost controls, and plain software where that is the better answer.
Design, frontend, backend, mobile, cloud and QA in one team, so nothing falls between suppliers.
UK business hours, estimates in pounds, and a contract with a UK company. Our engineers are based in the UK and India.
A fixed-scope project, dedicated developers or a monthly retainer — and you can move between them as the work changes.
Code, IP, cloud accounts and documentation are yours from day one. We sign an NDA before discovery if you need one.
We stay on for fixes, upgrades and new features, or hand over cleanly to your in-house team with the documentation to match.
FAQs
Straight answers on scope, cost, timelines and how we work. If yours is not here, ask us directly.
It depends on intended use. Software that handles administration — booking, routing, drafting letters a clinician edits — is generally treated differently from software that diagnoses, predicts risk or recommends treatment, but features such as summarisation can move closer to the line depending on how they are described and used. The MHRA regulates medical devices in the UK; we raise the question in discovery so you can take regulatory advice before the design is fixed.
We build an evaluation set from a de-identified sample of your own letters, notes or images, labelled by your clinicians or admin staff. The system is measured on it field by field and by document type, with particular attention to omissions — a missed allergy matters more than a misspelt name. Results go to your clinical safety lead before anyone relies on the output.
Summaries are generated from the source notes only, and every line links back to where it came from. We test specifically for omissions of high-risk items — allergies, medications, safeguarding flags — and show those items in fixed sections rather than leaving them to the model’s judgement. The clinician still reads the source for anything that affects care.
Wherever the task allows. Names, NHS numbers, addresses and dates can be removed or replaced before text reaches a model and re-attached afterwards inside your system. Some jobs, such as matching a letter to the right patient, need identifiers, so we keep that step inside your environment and document the data flow for your DPIA.
Yes. Several hosted model providers offer UK or European processing options, which we confirm for your chosen provider during design, and open models such as Llama or Mistral can run inside your own cloud account. The choice depends on your IG requirements, accuracy on your material and running cost.
Yes, as a draft. Speech-to-text produces a transcript, and a language model turns it into a letter or note in your template; the clinician edits and signs it before anything enters the record or reaches a patient. Patients should know recording is happening, and your IG and clinical safety leads decide how consent and retention work.
A dental health platform that uses computer vision to analyse dental X-rays and intraoral images and flag possible conditions for dentists to review, built with Python and TensorFlow on AWS. It follows the same pattern we apply elsewhere in healthcare: the model highlights, the clinician decides.
We are based in London, with onshore and offshore engineers in the UK and India. Most development runs on de-identified or synthetic data, so engineers rarely need identifiable records. Where live access is unavoidable, it is limited to named people you approve, and logged. If your policies rule out access from outside the UK, tell us early and we will state plainly what we can and cannot provide.
A discovery sprint to fix the intended use, check the data and plan the evaluation starts from £2,000. The pilot is then quoted at a fixed price, with evaluation and assurance documentation shown as separate lines so the effort is visible. Model and API fees are paid to the provider, and we estimate them up front.
