Precision Personal Software · Small-business AI adoption · California

Every small business has the right to become AI-native without exposing its alpha or privacy!

We are a small business, and we build for small businesses. Tell us the outcome your business needs. We turn it into testable acceptance criteria, agree the scope and price in writing, and deliver software designed around the way you actually work — not a generic platform that asks you to change your business.

Tell us the outcome you need See what we have built

No false promises. The software outcome, acceptance criteria, price, scope and exclusions are written down before work begins. Changes happen only by agreement.

Precision Personal Software · Let Us Vibe for You

Let Us Vibe for You.

Your business should shape the software. The software should not reshape your business.

AI made first versions faster. It did not remove the need to understand a workflow, make sound engineering decisions, test the result, document it and keep it working. Precision Personal Software brings those pieces together for small businesses that need a specific result, not another generic subscription.

You bring the problem and the outcome you need. Together we turn that into acceptance criteria we can both test. We agree the price, scope and exclusions in writing, build with our agentic AI framework, and deliver maintainable software designed around how your business actually works.

You define the goal, and you define “done”We don’t start until we both agree what finished looks like. Your acceptance criteria are the specification — not a wishlist we interpret later.
Outcome-based pricing. Never hourly.You are buying the agreed software result, not a block of our time. The price, scope and exclusions are written down before work starts.
No unexpected changesIf you ask for a different outcome, we explain the effect on scope, price and schedule. Nothing changes until we both agree in writing.
Built to be maintained, not just demoedReadable, documented, and structured so it can be extended — by us, by you, or by whoever you hire next. You own the software we deliver.

How Precision Personal Software works

Four steps, and the price is settled at step two.

  1. You tell us the goalWhat the software must do, and what “done” means to you.
  2. We define and price the outcomeAcceptance criteria, one outcome-based price, scope and exclusions — all in writing.
  3. We vibe itOur agentic AI framework does the building; our engineers own the result.
  4. We ship it to youWorking software, yours to run — and we can stay on to maintain and extend it.

Every engagement is scoped in writing first — the outcome, acceptance criteria, price and exclusions. This is a commitment to deliver the defined software result, not a promise of revenue, savings or any other wider business result. You own the software we deliver; our agentic framework and pre-existing tooling stay ours, licensed to you so you can run and extend what we ship. Submitting the form is an enquiry, not an order.

Why we exist

Small businesses should not be left behind by AI adoption.

Small businesses hear that they must adopt AI, then get offered enterprise platforms, open-ended consulting, or software that nobody can maintain. We believe they deserve something more practical: software built around a real workflow and a result they can test.

We know the constraint because we are a small business too. Time, cash and attention are limited. That is why we define the outcome, acceptance criteria, scope, exclusions and price before work begins. We do not promise that software will magically transform a business; we promise to be precise about what we will deliver.

Our research company began with special-needs assistive software. AI4Echolalia™, our full-stack educational speech-development platform for parent-mediated support, won second place at the TED AI San Francisco Hackathon in 2024 and remains a flagship licensing application. Deep2Lead™ / GemmaCure is our other flagship: a full-stack platform for learning AI-enabled drug discovery through gamification, supported by two published papers.

Precision Personal Software means a promise we can both read and test. You know what “done” means, what it costs, and what is outside the scope. If the requested outcome changes, we agree the effect on scope, price and schedule before additional work moves forward.

Active research · AI-enabled content creation

Our founders are ContentYog’s first customers.

ContentYog is our AI-enabled content platform. Our current research asks a practical question: can a small business create and distribute useful video consistently without an agency-sized budget? We are developing the editing, audio and post-production workflow, then using it first on the founders’ own YouTube channels.

This is how we eat our own dog food. Both founders have built channels with more than a thousand subscribers, their work has reached hundreds of thousands of views worldwide, and several videos have travelled far beyond the regular audience. The tools have to help us publish before we ask another small business to trust them.

Production, not luckWe won’t claim AI makes anyone go viral. It removes the hours between having something to say and having it published.
Local where it countsPost-production runs on Apple Silicon we already own. No per-render cloud bill, and the footage never leaves the machine.
We are our own first customerNothing we build leaves here until we have run it on our own channels first. If it is not good enough for our videos, we will not ask anyone to rely on it.

ContentYog for Mac — in development

A small business should be able to publish a real video every week without an agency, an editor, or a per-render cloud bill. We are building the thing that makes that true on a Mac. It is not ready to show yet, and we are not announcing features, pricing, or a date.

Active research · AI-enabled financial education

Understand the facts behind an asset — and test what the model gets right.

Our founders bring deep financial-domain experience, including contract work supporting a wealth-management company. This research turns that experience into education: how people value financial assets, how microeconomic and macroeconomic factors change the picture, and how an AI-enabled quantitative model performs when its output is measured rather than marketed.

The primary focus is stocks, with educational work also covering options and other derivatives, bonds, and assets such as gold and silver. We study company financials, market and economic data, real-time news, and disclosed trades from authoritative public records — including official congressional disclosures and SEC filings — rather than treating media commentary as the source of truth.

Facts before opinionsWe trace claims to company filings, official economic data, market data, congressional disclosures and SEC filings whenever those sources apply.
Models are experiments, not authoritiesAI and quantitative outputs are recorded, compared with what happened, and kept when they fail. A confident prediction is not treated as a fact.
Learn without tradingNo brokerage account, order routing or investment is required. The purpose is to make valuation evidence easier to understand.

What this is not

  • Not investment advice. Nothing is a recommendation to buy or sell, and nothing is personalised to your circumstances.
  • Not an investment firm. DLYog Lab is not registered as an investment adviser or a broker-dealer, and does not manage money for anyone.
  • Not a broker. No order routing, no account, no money held. You cannot trade through it.
  • Not a signal or copy-trading service. Public-figure or institutional disclosures are historical source data, not instructions to imitate a trade.

It is an education platform. Decisions — and their consequences — are entirely yours, and you should do your own research and consider speaking to someone qualified before acting on anything.

What our software and research are built on

Local AI, on hardware you own.

Small-business AI adoption has to make economic and operational sense. We invested in our own AI lab and in making models small and fast enough to run on machines people already own. That practical capability supports Precision Personal Software, our products, our research, and the advice we give California small businesses.

Our own compute

An in-house GPU lab we invested in and operate, used for training, fine-tuning and the cross-platform benchmarks we publish.

On-device inference

Models built to run on Apple Silicon without CUDA, without a cloud API, and without a network connection after installation.

Open weights

af_heart_arm_tts is a 68.5 MB Arm-optimised single-voice TTS model. Openly downloadable, with the research paper behind it.

Why you might believe any of this

We publish the numbers, not just the demo.

Everything above can be checked. The papers are published openly and our research is indexed by Google Scholar, the model weights are downloadable, the channels are live, and the one result that went against us is published rather than buried.

Questions people actually ask

Straight answers.

If you are trying to work out what this company is and whether it is for you, start here.

What does DLYog Lab actually do?

DLYog Lab is a California small business that builds Precision Personal Software for other California small businesses. Our commercial goal is practical AI adoption: software shaped around a customer’s workflow, delivered against written acceptance criteria with outcome-based pricing. We also conduct applied AI research and license AI4Echolalia™, our flagship assistive-education product.

Free research and public hackathon materials are available globally. Selected private previews may be offered outside California by invitation for a limited time under an NDA and separate written terms, with no payment by either party for preview access.

What is “Let Us Vibe for You”?

It is our delivery model for Precision Personal Software. You tell us the business outcome the software must support. Together we define the acceptance criteria that prove the software works, then agree the price, scope and exclusions before work begins.

There is no hourly billing. If the requested outcome changes, we agree any effect on scope, price or schedule before additional work proceeds. The commitment is the defined software result — not a guarantee of wider business performance.

How does outcome-based pricing work?

You describe the outcome and how we can test that it is done. We quote one price for that defined software result, with acceptance criteria, scope and exclusions written down. Then we build and deliver against that agreement.

Submitting an enquiry is not an order. We do not quote until we understand the outcome, and we do not change the price or scope without first agreeing the change with you.

Is InvestYog investment advice?

No. InvestYog is research and education about how financial assets may be valued and how AI-enabled quantitative models perform when tested. The primary focus is stocks, with educational work on options and other derivatives, bonds, gold and silver. It may examine company financials, economic factors, real-time news, market data, official congressional transaction disclosures and SEC filings.

DLYog Lab is not registered as an investment adviser or broker-dealer, does not manage money, and offers no recommendation, personalised guidance, signal, copy-trading, brokerage or trade execution. No trading or investment is required to learn from the research.

What is Sumi, and how does it help someone learn quantum computing?

Sumi is our voice-guided Agentic AI learning companion for 1StopQuantum. It can explain what is on the learning screen, take approved actions inside the application, and perform deterministic experiments so the learner can observe the result, understand what changed, and repeat it.

The full-stack application was submitted to OpenAI DevDay 2026. We are continuing the work as research into AI tooling, learning by doing, and voice-first education aligned with our VoiceYog initiative. Try the live proof case.

What is ContentYog?

ContentYog is our AI-enabled content platform in development. The founders are its first customers and use it for content creation and distribution through Deep Learning Connect and Mousumi Moments. This is how we test the platform on real publishing work before asking others to use it.

Our official company channel is DLYog Lab on YouTube. ContentYog remains in development; features, pricing, and release timing have not been announced.
