Feature Comparison

iGPT

Unified Intelligence Endpoint

iGPT consolidates the entire complexity of context engineering into a single, natural language API call. This unified endpoint seamlessly orchestrates real-time retrieval, sophisticated context shaping, and structured reasoning in one cohesive pipeline. Developers are liberated from the burden of managing multiple disparate services for parsing, vector stores, and prompt chains, enabling them to integrate powerful email intelligence with minimal code and operational overhead.

Autonomous Context Engineering

The platform autonomously handles the intricate tasks required to make email data usable for AI. This includes deep, automatic indexing of messages and attachments, intelligent reconstruction of email threads across time and participants, and optimized context window shaping for large language models. This sophisticated engineering happens behind the scenes, delivering clean, cited, and context-rich answers without any manual prompt tuning or maintenance from the user.

Enterprise-Grade Security Architecture

Security and data sovereignty are foundational to iGPT's design. It operates on a strict zero-data retention policy, processing each inference entirely in memory without storing inputs, prompts, or outputs. Coupled with OAuth-only authentication, rigorous Role-Based Access Control (RBAC), and comprehensive audit trails, it ensures that sensitive communication data never leaves a company's control and is never used to train external models.

Advanced Attachment & Thread Processing

iGPT excels at understanding the full context of communication by deeply processing not just email text, but all embedded attachments—including documents, PDFs, and spreadsheets—extracting their text, data, and structure. Furthermore, it intelligently reconstructs fragmented email threads, piecing together conversations across time and multiple participants to provide a complete and accurate narrative for the AI to reason over.

Zignt

Reusable Contract Templates

Zignt allows users to create contract templates once and reuse them indefinitely. This feature significantly reduces the time spent on contract preparation, enabling teams to focus on what truly matters. By simply adding date fields, text boxes, and signature blocks, users can establish templates that streamline their contractual processes.

Seamless Sharing Options

With Zignt, sharing contracts is effortless. Users can send contracts via email with automated reminders or opt to share a Zignt Link, akin to a payment link for contracts. This flexibility ensures that recipients receive contracts promptly, enhancing the likelihood of swift sign-offs and improved collaboration.

Instant Signed Document Delivery

Once all parties have signed, Zignt automatically delivers the executed PDF to each participant via email. This feature not only provides convenience but also includes vital compliance data, such as IP addresses, timestamps, and signer details, ensuring that every transaction adheres to legal standards.

AI-Powered Renewal Tracking

Zignt employs advanced AI capabilities to monitor contract renewal dates automatically, sending timely reminders to users. This proactive approach minimizes the risk of missed deadlines, allowing teams to stay organized and maintain control over their contractual obligations, thus fostering greater compliance and efficiency.

Use Cases

iGPT

Intelligent Email Assistants & Copilots

Build sophisticated AI agents that can draft, prioritize, summarize, and act on email with full situational awareness. These assistants understand the nuance of long threads, recognize urgency from tone, and can manage inboxes or draft contextually perfect responses by leveraging the entire history of a conversation and its related files.

Automated Workflow & Task Orchestration

Transform unstructured email exchanges into structured, actionable business processes. Automatically extract action items, deadlines, approvals, and decisions from board meetings or project updates, and convert them into tasks in tools like Jira or Asana. Proactively flag stalled conversations or follow-ups that require attention.

Customer Support & Relationship Intelligence

Empower support copilots and CRM agents with the complete customer story. iGPT can instantly rebuild a customer's journey from scattered email chains and attachments, allowing agents to understand past issues, commitments, and sentiment shifts. It can also extract deal momentum, ownership, and key decisions directly from sales threads.

Compliance, Audit, and Insight Generation

Create a verifiable audit trail of feedback, approvals, and operational rationale by tracing every AI-generated insight back to its source emails and attachments. Automatically summarize legal contracts, invoices, or reports within the context of the surrounding email discussion for faster review and insight discovery.

Frequently Asked Questions

iGPT FAQ

How does iGPT handle data privacy and security?

iGPT is built with enterprise-grade security as a core principle. It employs a zero-data retention model, meaning your data is processed in memory for the duration of an API call and is never written to disk or stored. Data is never used to train models. Access is strictly controlled via OAuth and RBAC, and every action is logged to a full audit trail, ensuring complete data sovereignty and compliance.

What is the "unified endpoint" and how does it simplify development?

The unified endpoint is a single API call (like /v1/recall/ask/) that replaces the need for a complex, multi-step retrieval-augmented generation (RAG) pipeline. Instead of developers managing separate services for ingestion, chunking, embedding, vector search, and prompt engineering, they simply send a natural language query. iGPT internally handles all those steps—retrieval, context shaping, and reasoning—returning a structured, cited answer.

Can iGPT process attachments within emails?

Yes, advanced attachment processing is a key capability. iGPT automatically extracts and indexes text, data, and structural information from a wide variety of file attachments, including PDFs, Word documents, spreadsheets, and presentations. This content is then made available for retrieval and reasoning in the context of the email thread, allowing questions about data within a report or terms in a contract to be answered accurately.

How quickly can I integrate and start using iGPT?

Integration is designed for immediacy. iGPT provides a live playground to test API requests with your own data, comprehensive SDKs, and detailed documentation. You can connect email sources, and the platform begins deep indexing automatically. This allows developers to go from sign-up to receiving contextual answers from their email data in a very short timeframe, accelerating prototyping and production deployment.
