Looking for an alternative to Tribble? 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.
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.
One AI workspace for RFPs, DDQs, and security questionnaires
HeyIris (the product is styled "Iris") is an AI-native response workspace that handles RFPs, RFIs, RFQs, DDQs, and security questionnaires in one environment. It builds a knowledge base from your uploaded documents and connected systems, then drafts responses with inline source citations and a confidence score on each answer, so contributors review and refine rather than write from scratch.
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.
Tribble scores 7.8/10 overall on our rubric. Tribble pairs source-cited, confidence-scored drafting with a Slack- and Teams-native delivery layer, so the same governed knowledge answers a formal questionnaire and a live buyer question. It holds G2's Fastest Implementation and Best Estimated ROI badges in the Enterprise RFP category (Spring 2026).
Its subscores are uneven: it rates 8.5/10 on ease of use but 7.5/10 on workflow & collaboration. Teams whose top priority is workflow and collaboration are the ones most likely to shortlist an alternative, since Tribble fits 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..
These are the limitations third-party reviewers most often cite about Tribble:

Inventive AI leads by 2.0 on autonomous drafting (10.0 vs 8.0). Overall, Inventive AI scores 9.3/10 to Tribble's 7.8/10.
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 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 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.
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.
