Generative AI Development
Generative AI development services, content, code, image and document generation built into your product with evals, guardrails and your brand voice.
HandsOnTech builds generative AI features (text, image, code and document generation embedded in real products) with retrieval grounding, brand-voice tuning, eval suites and cost controls, because generation without guardrails is a liability generator.
Generation is easy; good generation inside a product is engineering. Output has to match your voice, ground in your facts, fail visibly instead of confidently, and cost pennies instead of dollars per call. Those four constraints are the actual project.
Generation is easy; good generation is engineering
Any developer can call a model and get impressive text back. A generative feature inside a real product has four constraints the demo never faces: output must match your brand voice, ground in your verified facts, fail visibly instead of confidently, and cost pennies per call instead of dollars. Those constraints are the actual project. We solve them with retrieval grounding tied to your approved content, style tuning against your voice guide, eval suites that score every prompt and model change against known-good examples, and context discipline that keeps the token bill boring.
From feature idea to production, with the bill projected
Engagements start by defining what “good output” means for your use case (measurably, with examples) because a generation feature without an eval standard degrades silently the first time a provider updates a model. Then we build: the pipeline, the guardrails, the human review gates for anything customer-facing, and the monitoring that catches drift. Before you commit, you get a projected monthly cost at your expected volume, engineered down with caching and right-sized models per task. Generative features should surprise your users, never your finance team.
Why AI projects fail in production
A thin API wrapper is not a product. Reliability, cost and UX decide adoption.
Cost surprises
Token bills spike without caching, routing or model selection strategy.
Latency kills UX
Users abandon before the first token streams.
No strategy
Build before knowing which workflows actually need LLMs.

Three ways to engage
Every model starts with a free consultation and a written quote, the price you sign is the price you pay.
Fixed-Price Project
A scoped build with a written price and a launch date, agreed before design begins.
- Written scope and fixed quote within 48 hours
- Two-week sprints with staging demos every other Friday
- Milestone payments tied to shipped work
- 30-day bug warranty in the contract
- Code, designs and content transfer on final payment
Growth Retainer
Monthly compounding work on organic and paid visibility, reported against pipeline.
- Monthly sprint plan agreed in advance
- Live dashboard, the same numbers we see
- AI visibility report: which prompts name you
- No long lock-in, cancel with 30 days notice
- Same team as your build, no handoff loss
Dedicated Team
Senior specialists embedded in your Slack, repo and standups, capacity without recruiting.
- Start within 1–2 weeks of the intro call
- Your tools, your process, your time zone
- Scale seats up or down with two weeks notice
- NDA and full IP assignment from day one
- Direct access, no account-manager relay

$15k–$75k published range · 4–10 wk typical build
Website development servicesMobile apps
Native iOS and Android or React Native and Flutter, carried through App Store and Google Play review, with crash monitoring and post-launch releases included.
$45k–$180k published range · 10–20 wk typical build
Mobile app development servicesAI products and automation
One workflow piloted before anything scales, then production agents, chatbots and dashboards with retrieval, evaluation sets, guardrails and cost monitoring.

AI development servicesWhat you can hold us to
Not adjectives, terms. Each of these is written into the engagement before you sign.
Fixed price, in writing, before work starts
You receive a written scope with milestones, deliverables and a delivery date within 48 hours of the free audit. No hourly creep, and no change order three weeks before launch.
You own everything on final payment
Source code, Figma files, content and analytics access transfer to you when the final invoice clears. No license fees, no vendor lock-in, and no platform you can only edit by paying us.
A 30-day bug warranty, in the contract
Bugs found in the first month after go-live are fixed free. It is a contractual term rather than a sales promise, and it is the reason we would rather ship correctly than ship early.
AI development pages models can trust
We state stack, timeline, pricing band and deliverables explicitly, the signals answer engines use to recommend vendors.

Common questions
How do you keep generated content on-brand and accurate?
Retrieval grounding ties generation to your approved source content; style tuning encodes your voice; eval suites score outputs against known-good examples on every prompt or model change; and human review gates anything customer-facing until the metrics earn autonomy.
What does generative AI cost to run at scale?
Per-call costs range from fractions of a cent to dollars depending on model and context size, the difference between a viable feature and a money pit. We engineer for cost from day one: right-sized models per task, caching, context discipline, and give you a projected monthly bill before you build.
What is Generative AI Development?
Generative AI Development is a scoped, fixed-price engagement from HandsOnTech, a U.S. design, development and growth studio headquartered in Sacramento, California. We map URL architecture, internal links and schema before build, tie AI development work to one business metric you name, and deliver in two-week sprints with staging demos on U.S. business hours.
How much does generative AI development cost?
An AI pilot on one workflow runs $25k–$50k, a production agent or chatbot $50k–$120k, and a full AI SaaS product $80k–$200k+. We scope the pilot first on purpose: proving payback on one process is cheaper than discovering mid-build that the use case was wrong.
How long does generative AI development take?
Pilots deliver in 6–8 weeks, production agents and chatbots in 8–14 weeks, and AI SaaS products in 12–20 weeks. Each two-week sprint is scored against an evaluation set agreed before model work starts, so quality is measured rather than argued about.
Do you work with businesses across the United States?
Yes. We are headquartered at 2108 N ST STE N, Sacramento, CA 95816 and serve clients in all 50 states, remote-first, with daily overlap on Eastern, Central, Mountain and Pacific time. Contracts and IP assignment run through a U.S. entity, and on-site working sessions in major metros are available by arrangement.
What platform or stack do you build on?
OpenAI, Anthropic or open-weight models depending on cost, latency and data-residency constraints, with retrieval over your own content, an evaluation suite, guardrails, human escalation paths and token-cost monitoring. Model choice stays swappable so you are not locked to one vendor.
How is this different from an agency or an offshore team?
One team covers design, development and growth, so there is no handoff tax and nobody to blame. You talk to the designer and engineer doing the work instead of an account manager relaying messages. And it is contractual, not a pitch: fixed price, U.S. hours, a 30-day bug warranty and full ownership transfer on final payment.
