CustomGPTRECOMMENDED
Data Ingestion & Knowledge Sources
Builds custom pipelines to pull in pretty much any source—internal docs, FAQs, websites, databases, even proprietary APIs.
Works with all the usual suspects (PDF, DOCX, etc.) and can tap uncommon sources if the project needs it.
Project case study
Designs scalable setups—hardware, storage, indexing—to handle huge data sets and keep everything fresh with automated pipelines.
Learn more
Takes a code-first approach: plug in document-loader modules for just about any file type—from PDFs with PyPDF to CSV, JSON, or HTML via Unstructured.
Lets developers craft custom ingestion and indexing pipelines, so niche or proprietary data sources are no problem.
Lets you ingest more than 1,400 file formats—PDF, DOCX, TXT, Markdown, HTML, and many more—via simple drag-and-drop or API.
Crawls entire sites through sitemaps and URLs, automatically indexing public help-desk articles, FAQs, and docs.
Turns multimedia into text on the fly: YouTube videos, podcasts, and other media are auto-transcribed with built-in OCR and speech-to-text.
View Transcription Guide
Connects to Google Drive, SharePoint, Notion, Confluence, HubSpot, and more through API connectors or Zapier.

Supports both manual uploads and auto-sync retraining, so your knowledge base always stays up to date.
Integrations & Channels
Plugs the chatbot into any channel you need—web, mobile, Slack, Teams, or even legacy apps—tailored to your stack.
Spins up custom API endpoints or webhooks to hook into CRMs, ERPs, or ITSM tools (dev work included).
Integration approach
Ships without a built-in web UI, so you’ll build your own front-end or pair it with something like Streamlit or React.
Includes libraries and examples for Slack (and other platforms), but you’ll handle the coding and config yourself.
Embeds easily—a lightweight script or iframe drops the chat widget into any website or mobile app.
Offers ready-made hooks for Slack, Microsoft Teams, WhatsApp, Telegram, and Facebook Messenger.
Explore API Integrations
Connects with 5,000+ apps via Zapier and webhooks to automate your workflows.
Supports secure deployments with domain allowlisting and a ChatGPT Plugin for private use cases.
Core Chatbot Features
Builds a domain-tuned AI chatbot with multi-turn memory, context, and any language you need (local LLMs included).
Can add lead capture, human handoff, and tight workflow hooks (e.g., IT tickets) exactly as you specify.
Case study
Provides retrieval-augmented QA chains that blend LLM answers with data fetched from vector stores.
Supports multi-turn dialogue through configurable memory modules; you’ll add source citations manually if you need them.
Lets you build agents that call external APIs or tools for more advanced reasoning.
Powers retrieval-augmented Q&A with GPT-4 and GPT-3.5 Turbo, keeping answers anchored to your own content.
Reduces hallucinations by grounding replies in your data and adding source citations for transparency.
Benchmark Details
Handles multi-turn, context-aware chats with persistent history and solid conversation management.
Speaks 90+ languages, making global rollouts straightforward.
Includes extras like lead capture (email collection) and smooth handoff to a human when needed.
Customization & Branding
Everything’s bespoke: UI, tone, flows—whatever matches your brand.
Slots into your existing tools with custom styling and domain-specific dialogs—changes just take dev effort.
Custom approach
Gives you the framework to design any UI you want, but offers no out-of-the-box white-label or branding features.
Total freedom to match corporate branding—just expect extra lift to build or integrate your own interface.
Fully white-labels the widget—colors, logos, icons, CSS, everything can match your brand.
White-label Options
Provides a no-code dashboard to set welcome messages, bot names, and visual themes.
Lets you shape the AI’s persona and tone using pre-prompts and system instructions.
Uses domain allowlisting to ensure the chatbot appears only on approved sites.
L L M Model Options
Pick any model—GPT-4, Claude, Llama 2, Falcon—whatever fits your needs.
Fine-tune on proprietary data for insider terminology, but swapping models means a new build/deploy cycle.
Our services
Is completely model-agnostic—swap between OpenAI, Anthropic, Cohere, Hugging Face, and more through the same interface.
Easily adjust parameters and pick your embeddings or vector DB (FAISS, Pinecone, Weaviate) in just a few lines of code.
Taps into top models—OpenAI’s GPT-4, GPT-3.5 Turbo, and even Anthropic’s Claude for enterprise needs.
Automatically balances cost and performance by picking the right model for each request.
Model Selection Details
Uses proprietary prompt engineering and retrieval tweaks to return high-quality, citation-backed answers.
Handles all model management behind the scenes—no extra API keys or fine-tuning steps for you.
Developer Experience ( A P I & S D Ks)
Delivers a project-specific API—JSON over HTTP—made exactly for your endpoints.
Docs, samples, and support come straight from Deviniti engineers, not a public SDK.
Project example
Comes as a Python or JavaScript library you import directly—there’s no hosted REST API by default.
Extensive docs, tutorials, and a huge community smooth the learning curve—but you do need programming skills.
Reference
Ships a well-documented REST API for creating agents, managing projects, ingesting data, and querying chat.
APIÂ Documentation
Offers open-source SDKs—like the Python customgpt-client—plus Postman collections to speed integration.
Open-Source SDK
Backs you up with cookbooks, code samples, and step-by-step guides for every skill level.
Integration & Workflow
Deeply embeds into enterprise flows—internal portals, mobile apps, you name it—using custom code.
Can trigger ERP actions or open tickets automatically when the bot escalates a query.
Integration case
Chain together LLM calls, retrievers, and prompt templates directly in code to create custom workflows.
Fits into CI/CD and event-driven architectures, though you’ll script the automation yourself.
Gets you live fast with a low-code dashboard: create a project, add sources, and auto-index content in minutes.
Fits existing systems via API calls, webhooks, and Zapier—handy for automating CRM updates, email triggers, and more.
Auto-sync Feature
Slides into CI/CD pipelines so your knowledge base updates continuously without manual effort.
Performance & Accuracy
