What changed in RFP software this year

Response teams are doing more with the same people. In Loopio's 2026 RFP trends data, drawn from more than 1,500 teams, the average team answered 166 RFPs a year, up from 153, spent 33 hours on each one, and won 39% of them. 79% of teams said they had used generative AI in their RFP process, up from 68%.

The tools have split into two camps. Established platforms like Loopio, Responsive and Qvidian are built around a curated answer library, now with AI drafting on top. Newer AI-native tools like Inventive AI, Arphie, Tribble and AutoRFP.ai draft from the documents you already keep in Google Drive, SharePoint, Confluence or Notion, with less library upkeep. Most now show the sources behind each answer and a confidence score, and several connect to assistants like ChatGPT, Copilot and Claude through MCP (Model Context Protocol).

How we ranked: We looked at the quality of AI drafting and how it cites sources, the formats and portals each tool handles, collaboration and review workflows, CRM integrations, support for security questionnaires and DDQs (due diligence questionnaires), and how transparent pricing is. We did not run a hands-on bake-off for this edition.

The 8 tools compared

1. Loopio

Loopio is the most complete platform for teams whose job is answering RFPs.

What works: Loopio drafts answers from your approved library with citations and confidence scores, suggests which subject-matter expert should review each one, and routes answers for sign-off. It takes in RFPs from portals, Word, Excel and PDF, connects to Slack, Teams, Salesforce, Google Drive and OneDrive, and handles security questionnaires. Generative AI is included on every plan.

What doesn't: G2 reviewers say keeping the library current takes regular upkeep, and that AI suggestions can miss on very technical or niche questions. Pricing isn't published.

Best for: Proposal teams answering a steady flow of RFPs. The entry Foundations plan includes 10 seats, and pricing isn't public, as of October 2026.

2. Responsive

Responsive, formerly RFPIO, is the deepest platform for large organizations with many response teams.

What works: Agent Studio lets teams build their own no-code agents for parts of the process, and the Spring 2026 release added portal automation, which fills buyer portals and syncs answers back, plus an MCP server that brings approved answers into ChatGPT, Copilot and Claude. Pricing combines a platform fee with user licenses and allows unlimited projects.

What doesn't: G2 reviewers call the interface busy, with a steep learning curve and weak search.

Best for: Enterprises with several proposal, sales and security teams. The Emerging edition starts at $10,000, as of October 2026.

3. Inventive AI

Inventive AI is the pick for teams that would rather not maintain an answer library at all.

What works: It drafts from your live documents in SharePoint, Google Drive and Notion, with a Q&A library as an option, and an AI content manager flags answers that conflict or have gone out of date. It handles PDF, PowerPoint, Excel and CSV, connects to Salesforce, and covers RFPs and security questionnaires. Pricing includes unlimited users and is based on how many RFPs you run.

What doesn't: It's a young company whose last announced funding was a $4 million seed round in 2024, and its headline accuracy and win-rate claims are its own.

Best for: Mid-size teams whose knowledge lives in documents, not a library. Plans start at $10,000 a year, as of October 2026.

4. Tribble

Tribble fits presales and solutions engineering teams that already live in chat.

What works: Requests come in through Slack or Teams, every answer carries its source, and low-confidence answers go to the person who owns that topic. It exports to Word, Excel, PDF and buyer portals and connects to Salesforce, HubSpot, Google Drive, SharePoint, Confluence, Gong and Box. Respond is priced per project, with everyone who contributes included.

What doesn't: It's an early-stage company, and its sales assistant product widens its focus beyond RFPs. Prices aren't published.

Best for: Solutions engineers who answer RFPs alongside deals. Pricing isn't public, as of October 2026.

5. AutoRFP.ai

AutoRFP.ai is the tool with nothing hidden in its pricing.

What works: Every plan includes unlimited users and every feature, with no paid add-ons, and a project can be an RFP, DDQ, tender or security questionnaire. It drafts from Confluence, Notion, SharePoint, Google Drive, OneDrive and Zendesk, syncs both ways with Salesforce, handles portals with a Chrome extension, and offers an MCP server for Claude, ChatGPT, Copilot and Gemini.

What doesn't: The entry plan covers 24 projects a year, well below what busy teams answer, and there's a 12-month minimum term.

Best for: Mid-market teams that want a predictable bill. Scale is $899 a month billed annually for 24 projects a year, as of October 2026.

6. Arphie

Arphie is built for teams that need to check every AI answer before it goes out.

What works: Each answer shows its sources, a confidence score and the steps the AI took to reach it. Arphie connects live to Google Drive, SharePoint, Confluence, Notion, Seismic and Highspot, and Smart Merge removes duplicate answers. It's SOC 2 Type 2 compliant.

What doesn't: It has few reviews and a short track record, and pricing is by quote.

Best for: Teams in technical or regulated fields where accuracy matters most. Pricing isn't public, as of October 2026.

7. Conveyor

Conveyor specializes in the security reviews that slow down so many B2B deals.

What works: It answers security questionnaires in any format, works inside customer portals through a browser extension, runs a trust center where buyers can get documents themselves, and handles RFPs too. It connects to Salesforce, Slack and Jira, and pricing is usage-based with no per-user fees.

What doesn't: It's built for security reviews first, and its RFP features are newer than its questionnaire tools.

Best for: Security and sales teams buried in vendor security questionnaires. A limited free trust center is available, and pricing for automation is by quote, as of October 2026.

8. Upland Qvidian

Upland Qvidian is the long-standing choice for regulated enterprises that need control over every answer.

What works: AI Assist generates answers, AI rules enforce tone and terminology, and it parses questionnaires automatically. It handles DDQs and security questionnaires, integrates with Salesforce and Microsoft Office, and includes more than 70 reports.

What doesn't: It's built around a traditional answer library, so it feels less AI-native than newer tools, and pricing isn't published.

Best for: Financial services and other regulated enterprises with strict review rules. Pricing isn't public, as of October 2026.

Didn't make the cut

QorusDocs is a strong proposal builder for professional services firms on Microsoft 365, but it's built for crafted proposals more than high-volume questionnaires.

Vanta and SafeBase (now part of Drata) automate security questionnaires well, but they make the most sense if you already use their compliance platforms.

1up is a good budget pick with plans priced per questionnaire, but it's lighter on workflow and review.

Ombud has moved its focus to a broader revenue operations platform.

How to choose RFP response software

Decide between a library and connected sources. If you have a well-kept answer library and a dedicated team to maintain it, Loopio, Responsive or Qvidian fit. If your knowledge lives in documents across Drive, SharePoint and Confluence, look at Inventive AI, Arphie or AutoRFP.ai.

Count your volume and your contributors. Pricing per seat, per project and per usage can land in very different places. Count how many RFPs and questionnaires you answer a year and how many people contribute.

Test on a real RFP. Run a recent RFP through each finalist and check how many answers you'd send without edits, and whether each answer shows where it came from.

Check the portals and formats you face. If buyers send you to portals, confirm the tool can fill them as well as Word and Excel files.
