Custody
Privacy-first integration
OpenAI and peers supply intelligence; your rows, permissions, and audit trail stay in the database you control.

Erratum Solutions builds AI features inside your web or mobile product, using model providers like OpenAI while your system of record stays in your database.

Perspective
Many vendors sell AI as if you should move your business data into their cloud. We take the opposite default: the model reasons on requests you send, while customers, orders, and records of truth stay in your database.
That means retrieval over your schemas, role-aware tools, and logging you can explain to compliance and operations, not a black-box chatbot pasted onto a login screen.
Requirements vary: a branded assistant for your staff, customer chat grounded in your catalog, speech-to-text in a production tool, or predictors inside a financial app. We scope each build to the product you have and the outcome you need.

Assistants, semantic search, and automation call your APIs and database rules, not a parallel datastore you cannot audit.

Assistants, chat, transcription hooks, or prediction surfaces inside the screens they already use, not a separate tool they forget to visit.
Scoped AI shipped inside real apps: planned with your data rules, tested on staging, then tuned after launch.




Custody, product fit, and delivery treated as engineering work, not slide deck promises.
Custody
OpenAI and peers supply intelligence; your rows, permissions, and audit trail stay in the database you control.
Workflows
We design for the job you describe: internal Q&A, storefront guidance, transcription, scoring, or alerts tied to roles and workflows.
Delivery
The feature ships inside your screens with logging, fallbacks, and iteration from how staff or customers actually use it.
From workflow mapping through model integration, retrieval design, and launch, with demos your team can test on staging before production traffic.
01
We list which actions need AI, which tables and APIs are authoritative, and what must never leave your network.
02
We define RAG sources, tool calls, auth, logging, and fallbacks when a model or provider is unavailable.
03
We embed features in your app, rate-limit and monitor usage, and test edge cases with your team on staging.
04
We go live with monitoring in place, then refine prompts, retrieval, and UX from real usage and your team's feedback.
No. We integrate so each request carries only the context that workflow needs, often via retrieval from your database. Your system of record stays on your infrastructure.
Yes. That is the core of this practice: a scoped feature inside web or mobile software you already run, or a new module we ship alongside your stack.
Yes. We prefer extending existing products with APIs, admin tools, and auth you already trust, rather than forcing a separate platform.
We commonly work with OpenAI and can integrate other hosted or private models when your security, latency, or cost requirements call for it.
We use caching, retrieval limits, evaluation sets, and production monitoring so spend and answer quality stay predictable as usage grows.
Share the workflow, where data lives today, and what good looks like for users. We will reply with fit, boundaries, and a sensible first phase.
