Key takeaways
- Loopio and Responsive are the established RFP platforms, both enterprise-priced around $10,000 to $20,000 a year.
- AI-native tools like Inventive AI and AutoRFP.ai draft from connected sources instead of curated libraries, with monthly pricing.
- QorusDocs is the pick for Microsoft-centric teams; Qvidian suits Word and Excel-heavy enterprise proposal operations.
- PandaDoc and Proposify cover smaller teams that need proposals and RFP responses without enterprise contracts.
The best AI software for responding to RFPs and RFQs
An RFP lands with a two-week deadline and 400 questions, and half the answers already exist somewhere in your company. The tragedy of proposal work is not writing; it is finding. RFP response software exists to end the archaeology: a content library or AI that drafts answers from your past proposals, collaboration workflows, and exports that look professional. These eight tools span the old library model and the new AI-native model, and the difference matters more than any feature list.
#1
Loopio
Best for: mid-market teams with a dedicated content manager
Visit loopio.com
Starting price~$20,000/year
Free planNo
Loopio is the mid-market standard for RFP response: a centralized content library, collaboration workflows, and Magic AI that drafts answers, copy-edits and summarizes. It is known for the fastest onboarding in the category and consistently high support scores, which matters when a deadline is measured in days.
Pricing is quote-based, with third-party estimates around $20,000 a year for starting packages, and there is no free trial. Teams with a dedicated content manager get the most from it. Smaller teams should look at the AI-native tools below before committing to an enterprise contract.
What we like- Clean interface with fast onboarding
- Magic AI drafts and summaries
- Strong customer support reputation
Watch out for- Enterprise pricing with no public tiers
- Manual library upkeep
- No free trial
Starting price~$10,000/year
Free planNo
Responsive, formerly RFPIO, is the enterprise leader: a unified content hub with AI auto-drafting, adaptive learning and governance controls for complex, multi-team proposal operations. With over 1,300 G2 reviews, it has the deepest track record in the category, and its integrations span Salesforce, Slack and the full business stack.
Entry pricing is estimated around $10,000 a year, climbing with scale, and there is no public trial. It is built for mid-to-large enterprises running many concurrent RFPs, DDQs and security questionnaires. Small teams will find it heavy; large proposal operations will find it essential.
What we like- Broadest integration ecosystem
- Strong automation and governance
- 1,300+ G2 reviews
Watch out for- Steep learning curve
- Significant investment
- Intimidating for smaller teams

QorusDocs meets proposal teams where they live: inside Microsoft Word, PowerPoint and Outlook. Its QPilot AI assistant accelerates content research and generation without leaving the document, and the single source of truth keeps pitches, RFP responses and SOWs consistent. Professional services firms are a stronghold.
Pricing is quote-based, with reviewers noting it runs high per user in some markets. Google Workspace shops get less value from the Office-native design. For Microsoft-centric teams that live in Word, QorusDocs removes the most friction of any tool here.
What we like- Works inside Microsoft Word and Office apps
- QPilot AI assistant
- Strong customer support ratings
Watch out for- Quote-based pricing
- Microsoft focus is a limit for Google shops
- Enterprise-leaning
Starting price~$15,000/year
Free planNo
Qvidian, part of Upland Software, is the veteran of library-driven proposal automation: content management, automated document assembly and workflow controls for enterprises that run on Word and Excel. It remains the pick for proposal operations with deep governance needs and large content libraries.
Third-party estimates put pricing around $15,000 to $25,000 a year. The interface shows its age next to AI-native rivals, and implementation is a project. But for enterprises with thousands of curated answers and strict approval chains, Qvidian's depth still matters.
What we like- Deep content library and automation
- Built for complex enterprise RFP workflows
- Long track record
Watch out for- Dated interface
- Quote-based pricing around $15K to $25K a year
- Heavyweight implementation
Starting price$830/month (billed annually)
Free planNo
Inventive AI represents the AI-native shift: instead of maintaining a curated Q&A library, it drafts RFP, DDQ and questionnaire answers from your live connected knowledge, with conflict detection when sources disagree and support for narrative proposals. Pricing is $830 a month billed annually with unlimited users, which changes the math for large teams.
There is no free tier, and as a newer vendor it has a shorter track record than Loopio or Responsive. But the model solves the core pain of library tools, stale answers, and for teams drowning in questionnaires, that is worth the premium.
What we like- Drafts from connected sources, not stale libraries
- Conflict detection
- Unlimited users on the plan
Watch out for- $830 a month is steep for small teams
- Newer vendor
- No free tier
Starting price$899/month (24 projects/year)
Free planNo
AutoRFP.ai earns some of the highest value ratings in the category: AI-drafted RFP responses with project-based pricing at $899 a month for 24 projects a year. Reviewers praise the time savings and ROI, and several mention switching from the big platforms for lower administrative burden and faster setup.
The project cap means high-volume teams need to do the math, and the integration ecosystem is smaller than Responsive's. For mid-market teams that run a defined number of RFPs a year and want AI drafting without enterprise overhead, AutoRFP.ai is the value pick.
What we like- High reviewer ratings for value
- Project-based pricing
- Fast setup with low admin burden
Watch out for- $899 a month entry
- Project caps need watching
- Smaller ecosystem than the leaders
Starting price$19/user/month (annual)
Free planYes
PandaDoc is not a pure RFP tool, but for small businesses it often does the job: proposals, contracts and e-signatures in one platform with templates, a content library and CRM integrations. The Starter plan at $19 per user per month billed annually is a fraction of RFP platform pricing, and a free eSign plan covers basic signing.
Teams running formal RFP responses with hundreds of questions will outgrow it. But if your "RFP responses" are really polished proposals and quotes, PandaDoc delivers 80 percent of the value at 10 percent of the cost.
What we like- All-in-one proposals, contracts and e-signatures
- Free eSign plan
- 3,700+ G2 reviews
Watch out for- Not a dedicated RFP automation platform
- AI features are lighter
- Best for simpler proposal workflows
Starting price$19/user/month
Free planFree trial
Proposify gives sales teams control over proposals: locked templates, approval workflows and analytics showing which sections clients actually read. At $19 per user per month with a 14-day trial, it is priced for sales teams, not proposal departments.
It will not auto-answer a 400-question RFP. But for teams whose RFQ responses are really quotes and proposals that need to look sharp and close deals, Proposify's engagement analytics, knowing the client spent six minutes on pricing, are genuinely useful.
What we like- Content control and approval workflows
- Deal analytics show client engagement
- 14-day free trial
Watch out for- Proposal-focused, not RFP automation
- Per-user pricing scales
- No free plan
How to choose AI software for RFP and RFQ responses
Choose your model first: library or AI-native. Library tools like Loopio, Responsive and Qvidian depend on curated, maintained answer libraries; they are only as good as your content manager. AI-native tools like Inventive AI and AutoRFP.ai draft from your live sources, which removes the maintenance burden but needs good source material. The industry is moving toward the second model; buy accordingly.
Count your annual RFP volume before looking at prices. Project-based pricing like AutoRFP.ai wins at defined volumes; unlimited-user plans like Inventive AI win for large teams; per-user tools like PandaDoc win for small teams. A $20,000-a-year platform is cheap if it wins one extra deal and ruinous if you run six RFPs a year.
Trial with a real RFP. Every serious tool here offers demos or trials. Run the same past RFP through two finalists and compare draft quality, not feature lists. The tool whose first draft needs the least rewriting is the one that will actually save your team time.
Frequently asked questions
What is RFP response software?
Software that helps teams answer requests for proposals, quotes and information faster: a content library or AI drafts answers from past responses, collaboration tools manage the workflow, and exports produce professional documents. It replaces the chaos of email threads and shared drives during proposal season.
How much does RFP software cost?
Widely. PandaDoc and Proposify start at $19 per user per month; Inventive AI is $830 a month; AutoRFP.ai is $899 a month for 24 projects; Loopio, Responsive, QorusDocs and Qvidian are quote-based, roughly $10,000 to $25,000 a year. Match the pricing model to your RFP volume.
Can AI write RFP responses automatically?
It drafts them, and the drafts keep getting better. AI-native tools generate answers from your connected knowledge with conflict detection, while library tools auto-suggest curated answers. Human review remains essential: AI can misstate capabilities or miss nuance that costs deals. Treat it as a fast first draft, never a submission.
What is the difference between Loopio and Responsive?
Loopio targets small-to-mid teams with faster onboarding and a cleaner interface; Responsive targets mid-to-large enterprises with broader integrations and deeper automation. Both are library-based platforms with AI drafting. AI-native alternatives like Inventive AI skip the library model entirely.
Do I need RFP software for a small business?
Probably not the enterprise kind. If you answer a few RFPs a year, PandaDoc or Proposify at $19 per user per month handles proposals well. Dedicated RFP platforms earn their keep when volume, question counts or compliance requirements overwhelm manual processes.
