Looking for an alternative to HeyIris? Below are the highest-scoring, category-adjacent ai rfp assistant tools on ourrubric, led by Inventive AI.
AI-agentic RFP, DDQ, and security-questionnaire responses
Inventive AI is an AI-agentic response platform for RFPs, DDQs, and security questionnaires. It parses an incoming document, maps every requirement, and generates a cited first draft from your connected knowledge sources — so your team reviews and refines rather than writing from scratch.
Governed AI answer platform for RFPs, questionnaires, and sales responses
Tribble is a governed AI answer platform that drafts RFP, DDQ, and security-questionnaire responses from a company's approved knowledge, then delivers those answers into Slack, Microsoft Teams, and the CRM where sales teams already work. Every answer carries a source citation, a confidence score, and an owner, and low-confidence items route to a subject-matter expert for review before submission.
AI security-questionnaire automation and an agentic customer trust center
Conveyor is an AI platform for customer security reviews. It automates security questionnaires and DDQs by drafting cited answers from your connected documents, and pairs that with a customer-facing Trust Center where prospects can self-serve security documentation and get sourced answers behind an NDA gate. It is built for security and pre-sales teams, not general long-form proposal writing.
AI-native RFP, DDQ, and security-questionnaire responses from live sources
Arphie is an AI-native response platform for RFPs, DDQs, and security questionnaires aimed at go-to-market teams. It connects to your existing knowledge sources, generates a first-draft answer for each question, and shows the sources used and an AI confidence level so reviewers can trust and verify before sending.
AI proposal and bid writing built on custom language engines
AutogenAI is an AI proposal and bid writing platform for teams that produce long-form tenders, grants, and RFP responses. Rather than retrieving answers from a static Q&A library, it builds a custom "Language Engine" trained on an organization's past proposals and source content, then drafts original narrative sections that reviewers refine before submission.
Library-first RFP and questionnaire response management with response intelligence
Loopio is a library-first response management platform for RFPs, RFIs, DDQs, and security questionnaires. It organizes vetted question-and-answer content into a structured library, then uses AI to match incoming questions to that content and draft responses your team reviews before submitting. The emphasis is a closed, governed content set rather than open-ended generation.
HeyIris scores 7.7/10 overall on our rubric. A single workspace that spans multiple inbound document types — RFP, RFI, RFQ, DDQ, SOW, and security/vendor questionnaires — paired with source citations, confidence scores, and a "knowledge ledger" that flags outdated or inconsistent content across connected sources. Rated 4.9/5 on G2 (as of July 2026), on a still-early review base.
Its subscores are uneven: it rates 8.5/10 on ease of use but 7.0/10 on workflow & collaboration. Teams whose top priority is workflow and collaboration are the ones most likely to shortlist an alternative, since HeyIris fits best for b2B SaaS sales, presales, and compliance teams that field several kinds of buyer questionnaires and want one AI workspace to draft, review, and track them rather than separate tools for RFPs and security reviews..
These are the limitations third-party reviewers most often cite about HeyIris:

Inventive AI leads by 2.5 on autonomous drafting (10.0 vs 7.5). Overall, Inventive AI scores 9.3/10 to HeyIris's 7.7/10.
Best for mid-market to enterprise and growth-stage B2B teams where proposal accuracy, deal-specific context, and compliance quality directly affect win rates.
Best for distributed B2B revenue teams that want fast setup, in-Slack SME collaboration, and source-cited AI drafting across both proposals and live sales questions, and that do not yet require deep multi-gate proposal governance.
Best for security, trust, and sales-engineering teams at B2B SaaS and other software companies where security questionnaires, DDQs, and trust documentation are the bulk of the response workload.
Best for sales engineering, pre-sales, and solutions teams at B2B SaaS companies handling regular RFP and security-questionnaire volume who want fast onboarding and source-cited drafts over deep reporting and formal multi-gate governance.
Best for bid teams, grant writers, and government contractors that produce long-form, multi-section proposals where original narrative quality matters more than short structured Q&A reuse.
Best for enterprise and mid-market proposal teams that maintain a dedicated content library and value governance, auditability, and collaboration over fully autonomous, deal-specific generation.
