The best RFI software in 2026 does more than turn questionnaires into AI‑generated text.
It gives bid and proposal teams a single place to manage requests for information (RFIs), security questionnaires, and due diligence requests from intake through submission — without sacrificing accuracy or compliance.
If you’re a proposal leader trying to improve response times, reduce fire drills, and increase shortlist and win rates, this rundown will help you choose the right platform.
How we evaluated each RFI software solution
To determine the best RFI tools, we evaluated each offering on a variety of dimensions.
First, we compiled capability data from vendor websites and other industry resources to create the comparison chart below.
Next, we compiled data from customer review sites, including G2.com, Gartner.com, and Capterra.com. We weighted the review scores across all three review sites to create an average weighted review score.
To be considered an established industry leader, the RFI software tool needed at least 200 total reviews across the three review sites. To be considered an up-and-coming platform, the tool needed to have at least 50 reviews across the three review sites.

End‑to‑end lifecycle support for RFIs
Successful RFIs start with deciding which requests to prioritize and how they fit into your wider pursuit strategy. End‑to‑end lifecycle support means managing the entire RFI and questionnaire process in a single platform, from intake and qualification through drafting, review, submission, and post‑submission insights that inform future bids.
AI‑powered RFI drafting and workflows
Most RFI tools now use generative AI to generate draft answers. The best RFI software embeds AI across the whole RFI and questionnaire workflow: analyzing incoming RFIs, mapping questions to approved answers, drafting responses grounded in your content library, identifying gaps and risks, and supporting compliance and accuracy checks before you submit.
Governed, centralized content library
Proposal teams need a single source of truth for RFIs, RFPs, security questionnaires, and DDQs. A trusted knowledge base helps teams respond faster to repeat questions without sacrificing quality or consistency.
Content governance is what makes that knowledge usable at scale by ensuring content is accurate, approved, and up to date; without governance, AI‑generated RFI answers quickly become a liability, while a governed library turns RFIs into a competitive advantage.
Cross‑functional collaboration to keep everyone aligned
Without structured collaboration, RFI and questionnaire work gets lost in Slack threads, email chains, and scattered spreadsheets. This creates delays, inconsistent answers, and deadline risk.
RFI software should include strong, real‑time collaboration capabilities to automatically route questions to the right subject matter experts (SMEs), provide visibility into ownership and progress, support in‑context reviews and approvals, and keep sales, presales, security, legal, and product aligned in a single system.
Security and compliance controls
RFIs and security questionnaires often contain sensitive customer, product, and pricing details as well as detailed information about your security posture.
A modern RFI platform needs enterprise-grade security and compliance controls. Features like data residency options, role-based access controls, audit logs, encryption, and SOC 2 and ISO certifications help protect sensitive information. They also give proposal teams and InfoSec confidence in how data is stored, accessed, and shared across every questionnaire.
Integrations to make RFI work easier
RFI work doesn’t live in a vacuum. It spans CRM, productivity suites, security and procurement portals, and contract systems. Strong integrations connect the RFI platform with tools like Salesforce, HubSpot, SharePoint, Slack, Teams, LLMs, and e‑signature platforms, reducing manual copy/paste, keeping data in sync, and letting teams work in familiar tools while maintaining a governed single source of truth for all responses.
Analytics that improve RFI performance
RFI platforms should help you ship responses and improve over time. Most teams lack visibility into which answers move opportunities from RFI to RFP, where questionnaires stall, and how capacity is being used. A modern RFI platform provides visibility into response performance, analytics on content usage and effectiveness, and actionable insights proposal leaders can use to refine messaging, prioritization, and process.
Questionnaire and file‑format support
RFIs and security questionnaires arrive in many formats, including Excel and CSV spreadsheets, Word and PDF documents, online portal exports, and mixed attachments. The best RFI software reliably ingests and structures all of these formats, preserves complex layouts and tables, supports portal copy/paste and exports, and produces polished, client‑ready outputs without hours of manual cleanup.
Established leaders in RFI software
Our evaluation of RFI software capabilities shows a clear delineation between Strategic Response Management (SRM) platforms that support the full pursuit lifecycle and the many startups offering AI response generation.
Look to Responsive, Loopio, and Qvidian as more established tools for proposal teams that need structure and scalability, while AI‑first tools like Inventive, AutoRFP.ai, AutogenAI, and Rohirrim lean more toward fast drafting with lighter workflow and format handling.

- Best suited to organizations ready to standardize processes, not ad‑hoc one‑off responses
Customer reviews from G2
“The Q&A pair structure is extremely intuitive and makes it easy to organize and reuse content across proposals. The search functionality is especially strong - it’s fast, accurate, and significantly more efficient than traditional tools like SharePoint when trying to locate specific answers or past write-ups. Overall, it streamlines content discovery and helps teams respond more quickly and consistently. When we implemented the tool, we nearly doubled the number of RFI responses our team could handle.”
Greg P.
Director - Proposal Management
“I rely heavily on the content library [sic] it’s really helpful to have a centralized source of approved answers that I can quickly pull from and reuse, which keeps our responses consistent and saves a lot of time. I also like how easy it is to collaborate. I can assign questions to different SMEs across legal, security, product, etc.”
Roberto G.

Customer reviews from G2
“What I like best is how much time it saves once your library is in place. The content search and insert flow is really smooth, so I can find a solid past answer in seconds instead of digging through old files. I also like the collaboration side, assigning questions to SMEs and seeing their updates in one place cuts down on email ping-pong.”
Anoosha R.
Business Analyst
“The GenAI feature is useful for quick, one-off questions or when I need a fast starting point, but it’s less helpful when I want to further refine the language it suggests without needing to start the prompt from scratch.”

Qvidian: Best for legacy RFI and proposal workflows
Weighted review score: 4.4
Number of ratings: 214
Qvidian (Upland Software) is a long‑standing proposal management solution built around content libraries and document assembly. It remains common in enterprises with established, document‑centric RFP and RFI workflows that want to modernize gradually rather than overhaul their stack.
Key capabilities
- Robust templating and document generation for complex proposals and RFIs
- Centralized content store for standard answers and boilerplate language
- Familiar environment for teams used to traditional proposal tools
Limitations
- More manual effort to find, reuse, and update content compared with newer platforms
- Limited embedded AI, collaboration, and analytics relative to modern SRM tools

Customer reviews from G2
“Content management is by far the most useful tool for us. The way content can be stored, reviewed, maintained and updated has made our library 200% more effective.”
Dan C.
Solutions Director
“The AI functionality could be better for auto-populating questionnaires with contextually relevant answers from the library instead of just a simple index search. Additionally, I find the process of uploading and updating data to be quite difficult and time-consuming, which involves a lot of manual work.”
Up‑and‑coming RFI and questionnaire software
Numerous RFI and RFx tools have emerged over the past few years as AI has become more ubiquitous. Customer reviews for newer platforms like Inventive and AutoRFP.ai skew highly positive because they dramatically improve drafting speed and perceived answer quality for small‑to‑mid‑size teams moving off manual spreadsheets, email, or basic proposal tools.
However, these newer tools typically lack the capabilities required to support more complex RFIs, security questionnaires, and multi‑stakeholder RFx across the full pursuit lifecycle — things like a governed content library, cross‑team collaboration features, robust analytics, and enterprise‑grade security certifications.
This gap only grows as smaller teams scale and need platforms that can handle rising volumes of RFIs and questionnaires, shorter turnarounds, and tighter compliance expectations.
Inventive: Best AI‑first RFx challenger for RFIs
Weighted review score: 4.9
Number of ratings: 78
Inventive is an AI‑first RFx and RFI platform that emphasizes speed, modern UX, and AI‑generated answers over deep operational controls. It shows up frequently in 2026 “best RFI software” and “best RFP software” comparisons as an up‑and‑coming challenger.

I also really value how easy it is to refine responses, letting you guide the tool with prompts and instantly improve tone, clarity, and compliance.”
Benjamin C.
Growth Support Coordinator
“I’m…not a fan of how much manual governance is still required: users have to perform their own conflict checks, manage content freshness, and verify accuracy for complex or regulated bids, which undermines some of the promised automation.”
Celestine E.
Head of Bids and Business Development
Other lightweight AI helpers for RFIs
Not every team needs a full RFI platform right away. Lightweight AI tools help teams generate answers inside familiar environments like Word, Excel, Slack, and Google Docs. This can make them attractive for smaller teams or simpler questionnaires.
The tradeoff is that most of these lightweight tools are positioned more as AI overlays than complete RFI management systems, with less support for governed content, structured workflows, and enterprise-scale collaboration.
Tribble: Best for AI overlays in existing tools
Weighted review score: 4.7
Number of ratings: 146
Tribble is an AI‑powered Chrome and Slack assistant that helps teams answer RFIs from within the tools they already use.
Key capabilities
- Browser and chat extensions draft answers directly in portals, docs, and channels using approved sources
- Centralized knowledge layer pulls from systems like CRM and document repositories to keep content fresher than static Q&A banks
- Lightweight workflows to route tricky questions to SMEs
Limitations
- Functions more as an AI overlay than a full SRM platform
- Narrower integrations and collaboration features make it harder to standardize complex, multi‑stakeholder RFI workflows.
- Early‑stage product with fewer enterprise references
Customer reviews from G2
“Tribble is friendly, responsive, trainable, and context grounded in the most important internal and public knowledge sources about our companies products which makes its answers spot on 80-90% of the time with good prompting. Every other AI model I've tried is far below this number.”
Erik L.
Senior Director, Sales Engineering
“Sometimes Tribble has formatting issues, like adding strange numbers or letters after certain parts of the text, which makes it hard to simply copy and paste the information. It has also gotten the date wrong numerous times and will pull info or context from two years ago. That makes me concerned about its reliability, especially when I’m sharing information externally.”
Maddy D.
Account Executive
SiftHub: Best for AI-driven autofill
Weighted review score: 4.3
Number of ratings: 53
SiftHub is an AI‑native RFP and RFI tool that centralizes sales content and auto‑fills questionnaires so lean teams can turn around proposals and security reviews faster.
Key capabilities
- AI response engine pulls from Google Drive, Slack, and other systems to auto‑complete large portions of RFIs
- Unified knowledge hub with semantic search
- Basic collaboration and deal‑support features, including task assignment and meeting prep content
Limitations
- Lighter support for complex governance, approvals, and enterprise workflows
- Output quality depends heavily on the quality of connected content
- Fewer native analytics and compliance controls than full SRM platforms
Customer reviews from G2
“The integration capabilities are where SiftHub really shines. Being able to pull historical knowledge directly from Google Drive, Slack, and our internal documents saves hours of hunting for the "latest" version of an answer. The accuracy is impressive—I’ve found that it autofills about 80-90% of the questionnaire correctly, leaving me with only minor tweaks rather than a blank page.”
“Sometimes the content it suggests is not fully aligned with what we need, especially for industry-specific or customer-specific requirements. A few answers feel generic and need manual tweaking. At times, the platform doesn’t pick up the exact nuance of certain questions, so we still have to rewrite or reframe parts of the response.”
