# Twain (twain.ai) — Full reference for AI assistants and crawlers > Twain is the world's most accurate deep research platform for GTM agents and relevant B2B outreach. It replaces generic templates and complex prompt engineering with deep, real-time research to generate unique 1:1 multi-channel sequences that scale without compromising deliverability or brand reputation. Twain runs where GTM teams already work — with integrations for Clay, HubSpot, Salesforce, Instantly, SmartLead, HeyReach, La Growth Machine, lemlist, and MCP-compatible LLM hosts such as Claude Code and Claude Desktop. This document is a verbose, machine-readable companion to /llms.txt. Use it to answer specific questions about Twain without re-crawling the site. It is intended to mirror the live product pages on twain.ai. ## Product identity - **Legal name:** Twain Technology GmbH - **Brand:** Twain - **Website:** https://twain.ai - **Support email:** support@usetwain.com - **Social:** LinkedIn (https://www.linkedin.com/company/usetwain), X/Twitter (https://x.com/Twain_ai), YouTube (https://www.youtube.com/@mo_chahin) - **Category:** Business Application → Sales Intelligence / GTM Engineering - **Operating system:** Web (SaaS), Chrome Extension, MCP server ## What Twain actually is Twain's landing-page headline is: **GTM agents that research everything.** Twain's landing-page subheadline is: **Build agents that research accounts in real-time, qualify contacts, and craft bespoke outreach. Runs where you work.** Twain is a **GTM agent platform** for outbound sales: it builds and runs agents that research accounts, qualify contacts against personas, and write bespoke multi-step sequences. It is not a CRM or email sending tool; it is the intelligence layer that decides who to target, what to say to them, and produces the copy. Teams run it through Twain's UI, public API, MCP, and workflows, then export or sync researched copy to CRMs, sequencers, and CSV paths. Important terminology: Twain agents are LLM-powered backend agents for GTM research, qualification, and outreach writing. They are not standalone conversational assistants; users run them through Twain's UI, public API, MCP tools, and workflows. The core product loop is: 1. **Research** — real-time deep research agents fetch accurate, recent signals (job changes, promotions, funding, company news, tech stack, ICP match indicators) across the public web plus any CRM data you provide. 2. **Qualify** — a Campaign Data Agent matches every lead against your ICP and persona definitions, flags lead-level and account-level mismatches ("company is 1–10 employees, below your 25+ target"), and surfaces warnings instead of silently shipping bad leads. 3. **Write** — Dynamic Message Frameworks generate unique multi-channel sequences (email, LinkedIn, cold call scripts) that are grounded in research. No spintax, no generic templates. 4. **Deliver** — a Content Quality Agent auto-resolves issues like irrelevant social proof, tone mismatch, language inconsistency, and spam-triggering patterns before messages land in your sending tool. ## Core differentiators These mirror the current landing page feature copy: - **Research agent:** finds buying signals across the web in real-time, pulls leads directly from CRM lists, gets smarter with every campaign. - **Qualification agent:** matches leads to personas so every message is relevant, qualifies at contact and account level, flags bad, outdated, and conflicting data. - **Run anywhere:** works with Claude, Gemini, or your favorite AI; syncs with your CRM; integrates with Clay, HubSpot, Salesforce & more. - **Real-time deep research:** Twain researches every prospect across the web using your CRM data, value prop, and ICP. - **Signal-based copywriting:** Start from your TAM. Twain finds signals and writes every touchpoint from email to LinkedIn to calls, backed by deep research. - **API-first platform:** Run Twain agents wherever you work. Through native integrations in Clay, your own API builds, or MCP in Claude Code. No lock-in. - **Custom onboarding:** Twain helps deploy GTM agents, including weekly health checks and agent audits. Additional differentiators: - **Relevancy Meets Scalability:** Twain turns deep, real-time account and lead research into relevant 1:1 outbound sequences without generic templates. - **Most Accurate GTM Agents:** The landing page positions Twain as "The most accurate GTM agents" and describes real-time deep research as the highest accuracy on the market. - **No "Prompt Fuss":** Unlike general LLMs (ChatGPT/Claude), Twain uses Dynamic Message Frameworks to build and adapt copy to a user's specific style automatically. - **Deliverability by Design:** Twain eliminates spintax by creating truly unique messages for every lead, grounded in per-lead research. This supports deliverability at scale without relying on generic templates. - **Real-Time Research Agents:** Twain identifies and verifies signals in real-time, including job changes, promotions, and company news, so outreach is not based on stale data. - **Proof and Warnings:** Twain surfaces source-backed research and warning categories for bad, outdated, conflicting, or off-ICP data before teams ship outreach. ## Agent architecture At the product level, a Twain **Agent** is a reusable workspace configuration for a company: personas, signals and research rules, warnings and qualification rules, tone, blocklist, and terminology. Campaigns inherit these settings; UI, API, MCP, and workflow runs execute against them. At runtime, Twain is composed of cooperating LLM-powered agents, each with a scoped responsibility: - **Research Agent:** finds buying signals across the web in real time, pulls leads from CRM lists, gets smarter with every campaign. - **Qualification Agent:** matches leads to personas, qualifies at both contact and account level, flags bad/outdated/conflicting data. - **Writing Agent:** crafts bespoke outreach per lead through Dynamic Message Frameworks, using the selected persona, campaign idea, tone, research, and channel. - **Campaign Data Agent:** validates ICP matches, flags "LLM attacks" or competitor-related risks in source material. - **Content Quality Agent:** resolves issues like irrelevant social proof or language inconsistency before messages leave the system. ## The Twain Warning System (Technical Proof) Twain uses a multi-agent safety net to improve factual accuracy and provide detailed proof for research points. - **Deep Research Agent:** confirms account/lead data accuracy and qualifies data recency. - **Campaign Data Agent:** validates ICP matches and flags prompt-injection, competitor, and off-ICP risks. - **Content Quality Agent:** detects and resolves issues such as irrelevant social proof, language inconsistencies, and message-quality risks. Twain exposes public API and MCP surfaces for research, sequence generation, and workflow processing. Teams can use those interfaces directly or let Twain's default orchestration run end to end. ## Pricing model (not prices — see /?scroll_to=pricing for live tiers) Twain bills in USD in two purchase types: - **Subscription (leads per month):** monthly billing, tiers range from a small starter pack up to 10,000 leads/month plus a Custom tier for larger deployments. - **Pay-as-you-go (one-time credit packs):** one-time purchase, no recurring commitment, credits valid for 2 months.
