Agency proposal generation remains heavily manual in 2026. Most shops still Frankenstein Word docs, pulling case studies from Dropbox and pricing tables from spreadsheets. AI tools promise to streamline this, but the landscape is fragmented. Some are built for outbound sales sequences. Others are presentation builders repurposed for proposals. And some are just ChatGPT with marketing.
How we approached this
We examined vendor documentation, pricing pages, and feature lists for five tools frequently discussed in agency communities. Three products—Tome, Gamma, and Jasper—lack publicly visible pricing or feature detail as of June 2026; claims here reflect only what vendors publish. Regie.ai documentation was accessible. ChatGPT pricing is well-known.
Regie.ai
Regie.ai is an AI sales engagement platform designed for enterprise outbound teams—SDRs, AEs, and RevOps. Per the vendor's site, RegieOne orchestrates AI agents alongside human reps to automate lead sourcing, enrichment, personalized messaging, sequencing, and dialing. The platform integrates email, phone, social, and CRM in a single workflow.
Regie.ai
- +Built for end-to-end sales workflows, not just content generation
- +AI agents handle enrichment, sequencing, and CRM sync automatically
- +Unified dialing, email, and social in one interface
- +G2 reviews cite strong execution consistency
- −Designed for outbound sales teams, not agency proposal workflows
- −No public pricing; likely enterprise-tier
- −Overkill if you just need to draft proposal decks
- −Steep learning curve for non-sales use cases
Regie is not a proposal tool. It's a prospecting platform. If your agency runs high-volume outbound (cold email, LinkedIn, phone), Regie could orchestrate those motions. For one-off retainer proposals, it's architectural mismatch.
Tome
Tome markets itself as an AI presentation builder. No pricing page or detailed feature documentation was accessible as of June 2026. Vendor site was unreachable in research.
Tome
- +Reportedly AI-native presentation creation
- +Visual-first interface for pitch decks
- −No publicly accessible pricing or feature list
- −Unknown integration support
- −Unknown export formats or CRM connectivity
Gamma
Research returned a Dutch hardware store (GAMMA bouwmarkten). No AI proposal tool by this name was found with accessible documentation. If a product exists, it has no public web presence as of June 2026.
Gamma
- +None verified
- −No accessible vendor site or documentation
- −Product existence uncertain
ChatGPT
ChatGPT (OpenAI) is a general-purpose conversational AI. It's not a proposal platform, but agencies use it to draft scope-of-work sections, case study summaries, and pricing narratives. As of June 2026, ChatGPT Plus costs $20/mo; Teams is $25/user/mo with admin controls. Enterprise pricing is custom.
ChatGPT
- +Flexible: handles any text generation task
- +Low cost for solo users or small teams
- +No learning curve; natural-language prompts
- +Widely understood; easy to onboard staff
- −No built-in proposal templates or CRM integrations
- −Requires manual copy-paste into decks or PDFs
- −No version control or approval workflows
- −Output quality depends heavily on prompt skill
ChatGPT works if you already have a proposal template (Keynote, Google Slides, Notion) and just need AI to fill sections. It won't auto-pull case studies from Airtable or calculate pricing tiers. You write the prompt, copy the output, format manually.
Jasper
Jasper is an AI writing assistant for marketing teams. No pricing page or feature documentation was accessible as of June 2026. Historically, Jasper offered templates for blog posts, ad copy, and social captions; whether it supports structured proposal generation is unknown.
Jasper
- +Brand-voice training (historical feature)
- +Marketing-focused templates
- −No accessible pricing or current feature list
- −Unknown proposal-specific capabilities
- −Likely requires manual export and formatting
Verdict
- **If you run enterprise outbound sales (not proposals):** Regie.ai is purpose-built for SDR/AE workflows. Contact vendor for pricing; expect enterprise-tier cost.
- **If you need flexible, low-cost proposal drafting:** ChatGPT Plus ($20/mo) or Teams ($25/user/mo) paired with your existing template system (Keynote, Notion, Google Slides) is the most transparent option.
- **If you want a visual-first proposal builder:** Tome and Gamma are mentioned in agency circles, but neither has accessible pricing or feature docs as of June 2026. Verify directly before committing.
- **If you already use Jasper for marketing copy:** Check with vendor whether proposal generation is supported; pricing and feature set could not be confirmed.
What we'd skip
- **Regie.ai for one-off proposals.** It's a sales engagement platform for high-volume outbound. If you're not running sequences across hundreds of leads, you're paying for infrastructure you won't use.
- **Any tool without public pricing.** Tome, Gamma, and Jasper all lack transparent cost information. That's a red flag for budget-conscious agencies.
- **Tools that require manual copy-paste anyway.** If the AI can't integrate with your existing proposal stack (CRM, Airtable, Notion), you're just adding a step.
