Twain

What is Twain?
Twain researches prospects and drafts outbound sales messages that reference real buying signals instead of mail-merge placeholders. Its homepage invites you to run campaigns on 250 contacts for free, then uses research and qualification agents to shape email, LinkedIn, and call copy from your CRM data and ICP.
Template spinners swap first names and call it personalization. Twain pulls live signals from the web, matches leads to personas, and writes touchpoints that case studies on the site tie to 12% positive reply rates and ABM prep dropping from 6 hours to 25 minutes.
It fits SDR teams, founders doing outbound, and GTM agencies that integrate with Clay, HubSpot, or Salesforce. Pricing is credit based with one credit per lead for research or bespoke messaging, free regenerations, and credits that stay valid for 2 months on active subscriptions.
AI Proposal Builder

What is AI Proposal Builder?
AI Proposal Builder is Qwilr's free sales proposal generator that turns a company website URL into an interactive proposal draft. Paste your site, and the tool scans your messaging, offering, and design style, then builds a prospect-ready page using patterns from over 1 million proposals on the Qwilr platform.
Generic proposal templates make every deal look the same. AI Proposal Builder starts from your own website content, so the first draft already matches your brand voice. You can add videos, dynamic pricing cards, and ROI calculators in Qwilr's editor after generation, which is a different workflow than filling a static PDF template from scratch.
Sales reps, agency owners, and SaaS sellers use it to skip the blank page when pitching new deals. Generation is free without a Qwilr account, but editing and sending requires signing into Qwilr, where paid plans start at $35 per user per month on the Starter tier.
