6 Best Responsive (RFPIO) Alternatives (2026 Top Picks)

The best Responsive alternatives in 2026 are Arphie for teams that want AI-first drafting with citations, a soft FM specialist at number two for cleaning and security contractors bidding for UK contracts, and AI Tender Writer for UK SMEs bidding for public-sector work in any sector. Loopio, Inventive AI and QorusDocs complete the list, each with its own pricing and limits section.

People switch from Responsive for lighter set-up, clearer pricing, more AI writing or better UK tender fit. Responsive, which most people still know as RFPIO, is a serious enterprise platform, so the people looking for RFPIO alternatives usually aren't unhappy with the idea. They want a lighter set-up, a clearer price, more AI writing, or a tool that actually knows how UK public-sector tenders work. Which one fits depends on where your bids come from.

Responsive (RFPIO) at a glance¶

Responsive is strategic response management software. It rebranded from RFPIO and now covers RFPs, RFIs, security questionnaires, due diligence forms and proposals. Its core is a governed content library, with an AI response assistant, project workflow, analytics and connections to CRMs, cloud storage and collaboration tools. It's aimed at mid-sized and large organisations with dedicated proposal teams.

Its pricing page lists four editions (Lite, Emerging, Growth and Enterprise), and for most of them you'll need a quote. Higher editions add more features, user roles and collaboration options. Third-party pricing write-ups say costs depend on the edition, users and response volume.

Across reviews and comparison write-ups, the reasons teams look for Responsive alternatives are fairly consistent:

• Set-up effort. Getting value from a governed library needs time to migrate, tag and review content, plus someone to own it.
• Budget. Prices aren't published and costs grow with seats, which is hard for smaller teams to plan around.
• Breadth they don't use. Many smaller teams only need drafting and reuse, not multi-business-unit governance.
• AI drafting expectations. Newer AI-first tools write fuller first drafts from connected documents, and some teams want that approach.
• No UK tender feed. Responsive helps once you have an opportunity. It doesn't find UK public-sector tenders, score fit or cover PPN 002 social value.

How we picked these RFPIO alternatives¶

We treated each tool as a possible replacement for Responsive and scored it on six points:

• Coverage of the core job: reusing approved content across RFPs, questionnaires and proposals.
• AI drafting depth, and whether each answer shows its source.
• Time to value: how long before a new team gets a usable draft.
• UK public-sector fit: tender discovery, Selection Questionnaires, social value and Procurement Act 2023 language.
• Pricing clarity and a way to test without a long sales cycle.
• Data handling: storage location and whether your content trains models.

We didn't use review-site star ratings or vendor win-rate claims. Where pricing isn't published, we say so.

1. Arphie: Best for AI-first RFP and questionnaire teams¶

Arphie pricing

When to choose Arphie

• Library upkeep is the main cost of Responsive for your team.
• Your source content already sits in shared drives and wikis.
• You handle a lot of security and due diligence questionnaires.

Where Arphie falls short

• Prices aren't published.
• No UK tender discovery or bid/no-bid scoring.
• Not tuned for long, scored UK method statements.

2. CleanTender: Best for facilities management SMEs¶

CleanTender pricing

When to choose CleanTender

• You bid for cleaning, security, grounds, waste or catering contracts.
• You want FM-specific compliance checks before you commit bid time.
• You need a published monthly price rather than an enterprise contract.

Where CleanTender falls short

• Soft FM only: not designed for IT, works or professional services bids.
• No enterprise approval workflows or CRM connections.
• Drafts still need your own evidence and editing.

3. AI Tender Writer: Best for UK SMEs bidding for public-sector work¶

AI Tender Writer pricing

When to choose AI Tender Writer

• You bid for UK public-sector contracts in any sector.
• You want social value answers that follow the TOMs and PPN 002 approach.
• You want one fixed monthly cost with unlimited drafting.

Where AI Tender Writer falls short

• Not built for large sales teams answering global questionnaires.
• Lighter governance, roles and CRM connections than Responsive.
• Drafts still need your review and real evidence.

4. Loopio: Best for library-led RFP teams¶

Loopio pricing

When to choose Loopio

• You like the library approach but want to compare vendors.
• You have someone to own and review the content library.
• You answer many sales RFPs and security questionnaires.

Where Loopio falls short

• Prices aren't published.
• Same library upkeep as Responsive.
• No UK tender feed or social value support.

5. Inventive AI: Best for context-aware AI RFP drafting¶

Inventive AI pricing

When to choose Inventive AI

• You want AI-written first drafts from connected knowledge.
• Contradictions across old documents keep causing rework.
• Your work is mainly B2B sales RFPs.

Where Inventive AI falls short

• Prices aren't published.
• No UK tender feed.
• Not tuned to UK public-sector scoring or social value.

6. QorusDocs: Best for Microsoft 365 proposal teams¶

QorusDocs pricing

When to choose QorusDocs

• Your writers work in Word and won't adopt a separate app.
• You need branded templates as well as reusable answers.
• You run Microsoft 365 across the business.

Where QorusDocs falls short

• Prices aren't published.
• Less useful outside Microsoft 365.
• No UK tender feed or public-sector scoring.

Responsive alternatives pricing compared¶

How to choose a Responsive alternative¶

What to look for in a Responsive alternative¶

• Drafting that suits your questions. Short questionnaire answers suit a library; long, scored UK method statements suit drafting from evidence.
• A visible source for every answer, so reviewers can check claims quickly.
• Realistic set-up time. What most people get wrong here is underestimating the library work a governed platform needs.
• UK public-sector features if you bid for government work: tender discovery, Selection Questionnaire support and PPN 002 social value.
• Honest AI use. PPN 017 lets UK buyers ask how AI was used in a bid, so record the tool and your human review.
• Costs that don't jump every time someone new needs access.

Frankly, if most of your bids are UK public-sector tenders, an enterprise response platform is usually more tool than you need. Central government goods and services contracts above £139,688 follow the full Procurement Act 2023 process on Find a Tender, and they're won with evidence-led answers and strong social value, which is exactly where a UK-focused tool helps most.
