Talk to Sophie about any sales conversation and get an instant debrief — signal report, strategic next moves, a ready-to-send follow-up email, and the full transcript. No login, no API keys, no cost.
Try Sophie Free — sophie.mantyl.aiSophie is a voice-powered AI sales analyst that turns any sales conversation into structured, actionable intelligence. You talk to Sophie like you'd debrief a colleague after a call — describe what happened, what the prospect said, what concerned you — and she produces a complete debrief package that would normally take a senior sales analyst 30–45 minutes to assemble.
She doesn't just transcribe. She analyzes. Sophie identifies buying signals, red flags, competitive mentions, budget indicators, and timeline cues buried in your conversation. She synthesizes them into four deliverables that you can review, copy, and act on immediately.
Open Sophie and click the microphone. Tell her about your sales conversation — who you met, what they said, what you're selling, how they reacted. Sophie uses real-time voice recognition to capture everything naturally. Talk to her the same way you'd recap a call to your sales manager.
Sophie listens for nuance. Mention that a prospect "seemed hesitant about pricing" or "asked about a competitor" and she'll flag it as a signal. The more context you give, the sharper her analysis becomes.
Sophie doesn't just listen — she engages. Powered by GPT-4o for conversation and ElevenLabs for natural-sounding voice, she asks clarifying questions, probes for details you might have missed, and keeps the conversation focused on what matters for your debrief. She speaks back to you naturally, making it feel like a real conversation with a colleague.
When you're done, Sophie hands the entire conversation to Claude (Anthropic's AI) for deep analysis. Within seconds, you get four deliverables organized in a tabbed interface: Signal Report, Next Moves, Follow-Up Email, and Transcript. Each is formatted for enterprise readability — no raw text, no messy markdown. Clean, structured, ready to act on.
Each deliverable has a one-click copy button. Paste your signal report into Slack, your next moves into your CRM, your follow-up email into Gmail, and your transcript into your meeting notes. Sophie gives you everything pre-formatted so you can act immediately instead of spending 30 minutes writing post-call notes.
The signal report is Sophie's flagship deliverable. It breaks down your conversation into key findings — individual signals that Sophie identified from what you told her. Each finding is categorized (buying signal, objection, competitive mention, timeline cue, budget indicator, stakeholder insight) and presented as a standalone card with context. Below the findings, Sophie provides a diagnosis — her overall read on where the opportunity stands and what the signals mean when taken together.
Sophie doesn't just tell you what happened — she tells you what to do about it. Next moves are numbered, prioritized action items with a title and strategic description. They aren't generic advice like "follow up soon." They're specific to your conversation: "Send the ROI calculator to the CFO before Thursday's budget review" or "Loop in your SE to address the integration concerns they raised about their Salesforce setup."
Sophie drafts a complete follow-up email that references specific points from your conversation. It includes a subject line, greeting, body that acknowledges what was discussed, addresses any concerns raised, reinforces your value proposition, and includes a clear next step or CTA. The email is written to sound like it came from you, not a bot — professional, warm, and specific enough that the recipient knows you were paying attention.
The full conversation between you and Sophie, with speaker attribution (You vs. Sophie), preserved exactly as it happened. This serves as your source material — paste it into your CRM for complete call documentation, share it with your manager for coaching, or reference it when preparing for the next meeting.
All four deliverables are generated from a single conversation. Talk to Sophie for 2–5 minutes, and you'll have 30+ minutes worth of post-call work done for you — signal analysis, action planning, email drafting, and documentation.
Sophie is built voice-first. While most sales tools make you fill out forms or type notes, Sophie works the way sales actually happens — through conversation. The voice experience is powered by a dual-model architecture that separates the roles:
| Layer | Technology | Role |
|---|---|---|
| Voice Input | Web Speech API | Real-time speech-to-text with continuous recognition |
| Conversation AI | OpenAI GPT-4o | Intelligent conversation partner that asks the right follow-up questions |
| Voice Output | ElevenLabs TTS | Natural, human-sounding voice responses (not robotic text-to-speech) |
| Analysis Engine | Claude (Anthropic) | Deep conversation analysis and structured deliverable generation |
| Infrastructure | Netlify Functions | Serverless API proxy — no API keys exposed to the client |
This dual-model approach is deliberate. GPT-4o handles the real-time conversation because it's optimized for fast, natural dialogue. Claude handles the debrief analysis because it excels at structured reasoning and long-form synthesis. You get the best of both models without paying for either.
The tools that do what Sophie does cost real money. Most sales teams cobble together 3–4 platforms to get signal detection, conversation intelligence, follow-up automation, and call documentation. Here's what that typically looks like.
Sophie replaces $1,200+/month in SaaS tools with a single free conversation. She won't replace your entire Gong deployment if you have 200 reps. But for founders, small teams, individual AEs, and anyone who wants instant post-call intelligence without the enterprise price tag — she's everything you need.
Sophie isn't competing in the same lane as Gong, Clari, or Chorus. Those are enterprise platforms built for VP-level pipeline analytics across large teams. Sophie is a personal sales analyst — designed for the individual rep, founder, or small team who needs smart post-call support without the overhead.
Tools like Gong and Chorus work by recording your actual calls — which requires calendar integrations, meeting bot permissions, and your prospect's implicit consent to being recorded. Sophie works differently. You talk to Sophie after the call, debriefing her the way you'd tell a colleague what happened. This means no recording permissions, no bot joining your Zoom, no awkward "this call may be recorded" disclaimers. You control what Sophie knows because you're the one telling her.
Enterprise conversation intelligence platforms give you dashboards, trends, pipeline views, and analytics over time. Valuable for managers, but useless if you just need to send a follow-up email before your next call starts. Sophie gives you four concrete deliverables you can act on immediately: a signal report you can paste into Slack, next moves for your CRM, a follow-up email ready to send, and a transcript for documentation. No dashboard required.
Most sales intelligence tools require SSO configuration, CRM integration, call recording setup, team onboarding, and administrator involvement. Sophie requires nothing. Open the link, click the microphone, and talk. The entire backend runs on serverless functions with API keys managed server-side. You never see a setup screen, an API key input, or an admin panel.
Sophie isn't a 14-day free trial. She isn't a freemium plan with crippled features. She isn't a lead-gen bait-and-switch where you "try it free" and then get pestered by an SDR. Sophie is fully free with full functionality. Mantyl built her as a showcase of what AI can do for sales teams — and as a proof point for the custom automation work they do for clients.
You just finished a discovery call and your next one starts in 10 minutes. Instead of scribbling half-legible notes, talk to Sophie for 3 minutes and get a complete debrief with a ready-to-send follow-up email. Update your CRM with the signal report and move on.
You're the CEO, the CTO, and the head of sales. You don't have time for post-call admin work, but you can't afford to lose deal context either. Sophie captures everything and gives you structured intelligence so nothing falls through the cracks — even when you're juggling 15 other priorities.
Your team of 3–10 reps doesn't have the budget for Gong at $150/user/month. But you still need conversation intelligence to win more often. Sophie gives every rep on your team access to signal detection, strategic recommendations, and automated follow-ups at zero cost.
Have your reps debrief their calls with Sophie and share the signal reports with you. You get structured data about what's happening in every conversation without sitting in on every call. Use it for coaching, pipeline reviews, and identifying patterns across your team's deals.
No sign-up, no credit card, no setup. Open Sophie and debrief your last sales conversation in under 5 minutes. You'll get a signal report, next moves, a follow-up email, and a full transcript — free.
