From slash-command to inserted prompt.
We replaced six tools with Prompsy. The CFO finally knows what we spend on AI, and the prompt that closes our enterprise demos is now version-controlled.

The problem

Your team's best work is rotting in a Notion doc nobody opens.

Every AI-savvy person on your team has a private prompt graveyard: tabs, Notes.app, half-broken Slack threads. There's no audit trail, no optimization, no leverage.

01
Sprawl.

The good prompts live in Slack DMs, voice memos, and somebody's six-month-old laptop.

02
No governance.

Legal has no clue what prompts are touching customer data. The CFO doesn't either.

03
No optimization.

You wrote it once on a Tuesday. You'll never know if a different model or rewrite would be 40% cheaper or twice as good.

04
No leverage.

The one person who wrote the killer pitch prompt left. The institutional memory left with them.

A guided tour

The whole system, four moves at a time.

— Stop 01 · Bakeoffs

Same prompt. Six models. One winner.

Run any prompt across GPT-5, Gemini 3, Claude, and your private models in parallel. Auto-judge ranks by quality, latency, and cost — not vibes.

  • Side-by-side streaming output
  • LLM-as-judge with custom rubrics
  • Cost + latency baked into the verdict
— Stop 02 · Flows

Chain prompts into workflows that actually do work.

Conditional branches, loops, human approval gates, webhook calls. Run on demand, on schedule, or by event. Every step versioned and observable.

  • Visual node editor
  • Approval gates + retries
  • Webhooks in and out
— Stop 03 · Snap & Mirror

Reverse-engineer any output you admire.

Drop a screenshot or paste a piece of writing. Prompsy generates a Smart Prompt that produces work like it — saved straight to your library.

  • Vision-powered Smart Prompt extraction
  • Style, structure, and length captured
  • One-click save to library
— Stop 04 · Governance

Budgets, audit, and the legal team's wishlist.

Per-team and per-model budget caps. Signed audit log of every event. SSO, SCIM, BYOK, retention policies, and PII redaction — out of the box.

  • SSO / SCIM / RBAC
  • BYOK + data residency
  • Signed, exportable audit log

FAQ

The things you're about to ask.

Which models does Prompsy support?+

Gemini 2.5 & 3.x, GPT-5 family, Anthropic Claude, and any model exposed via the Lovable AI Gateway. Bakeoffs run them in parallel side-by-side.

Is my data used to train models?+

No. Prompsy never trains on your prompts or outputs. Enterprise plans add BYOK so prompts can be routed to providers under your contract.

How is this different from a Notion doc full of prompts?+

Prompts have variables, versions, runs, ratings, costs, audit trails, sharing rules, and live in the browser tabs you already use. Notion has none of this.

Will the Chrome extension work in ChatGPT, Claude.ai, and Gemini?+

Yes. Plus Perplexity and any standard text input on the web. Type /prompsy and go.

What does 'enterprise-ready' actually mean?+

SOC 2 path, SSO/SAML, SCIM provisioning, audit log of every event, role-based access, budget caps per team and model, GDPR export/delete, encryption at rest and in transit.

Can I import what I already have?+

Bring CSV, JSON, Markdown, or paste a Notion export. Prompsy auto-detects variables and tags.
