Architecture that stays consistent past feature five.

A prototype holds together for the demo. Then feature five arrives, and the decisions nobody wrote down start to collide — a second tenant, a billing edge case, an auth path no one pen-tested.

Ptah studies your codebase before the first message and keeps every architectural decision it makes, staffing the parts a solo prototype skips. The line stays flat.

One Desktop App. Real Sessions.

No slideware — this is Ptah running against real projects: memory recall, sub-agent fan-out, and scheduled runs, captured as they happened.

Ptah desktop — memory recall, sub-agent fan-out, scheduled runs.

PILLAR 1 — KNOWS YOUR ARCHITECTURE

It Knows Your Architecture. It Never Re-Learns It.

Vibe-coded prototypes forget every session — that is how duplicate services and missing auth checks pile up. Ptah indexes your project before the first message and keeps the decisions it makes after the last one, so feature ten stays as consistent as feature one.

Hybrid BM25 + vector memory search, fused with Reciprocal Rank Fusion.

  • Persistent Memory

    Hybrid BM25 and vector search, fused with Reciprocal Rank Fusion, recalls the architectural decisions, security fixes, and data-model conventions from session one — so the agent building feature five does not reinvent the auth pattern from feature one.

  • Tree-sitter Codebase Indexing

    Structural AST parsing across JavaScript, TypeScript, Python, and Go indexes every function, class, and import with exact file positions — the same map every agent works from, not a fresh guess per session.

  • Hybrid Symbol Search

    Ask 'where do we validate auth tokens' in plain English and get ranked, cited results injected straight into agent context.

PILLAR 2 — A STAFFED TEAM, NOT A SOLO AGENT

Delivery Patterns That Compound. A Staffed Team That Ships Them.

Ptah is not one generalist agent guessing at your stack — it is a staffed team: architect, backend developer, frontend developer, tester, and reviewer, each reusing the delivery pattern that worked last time instead of relearning it from scratch.

Up to 9 concurrent agent tiles — architect, backend, frontend, tester, and reviewer among them — in one gridstack view, each with an independent provider and model.

main orchestration · 3-tier Architect Backend Frontend Tester Reviewer 03 skills curator skills library skill orchestra canvas · 9 tiles · workflows library

  • Auto-Learning Skills Curator

    When a delivery pattern succeeds — a tenant-isolation guard, a billing webhook, a migration — Ptah extracts the trajectory, judges its quality, and promotes it to a permanent, shareable SKILL.md file. The tenth SaaS you ship reuses what the first one learned.

  • Sub-Agent Orchestration

    A main agent fans work out to specialist sub-agents — architect, backend developer, frontend developer, tester, reviewer — across a three-tier hierarchy, each with its own provider, model, and context window.

  • Orchestra Canvas

    Run up to nine concurrent agent sessions in one drag-and-resize grid — architecture in one tile, billing integration in another, tests in a third. Background agents keep working while you review a single tile.

  • Built-in Workflows & Skills Library

    Ship with pre-built delivery patterns for common SaaS stacks — multi-tenant setup, billing integration, auth guards — and browse more from the skills registry, install with one click.

PILLAR 3 — SHIPS OVERNIGHT, APPROVED FROM YOUR PHONE

It Keeps Shipping Overnight. You Approve From Telegram.

Schedule the next migration, the nightly security scan, the dependency bump like a cron job. Wake up to a diff waiting for your approval — from Telegram, Discord, or Slack, not a laptop you have to keep open.

Trigger and approve agent runs — including production-sensitive diffs — from Telegram, Discord, or Slack, including per-thread sessions on Discord.

cron scheduler · messaging gateways +voice · approval relay

  • Cron Scheduler

    SQLite-backed, slot-claimed scheduled runs. Nightly security reviews, Sunday dependency scans, the next ticket in the backlog — no server to babysit, no laptop that has to stay open.

  • Messaging Gateways

    Trigger and approve agent work from Telegram, Discord, or Slack, including voice input. Discord supports per-thread multi-session conversations, so each thread keeps its own agent context.

  • Approval Relay

    Review and approve every tool call and diff before it executes — including the ones that touch billing, auth, or tenant isolation — from any connected gateway. Nothing ships unattended that you haven't signed off on.

CROSS-VENDOR REVIEW, NOT SELF-GRADED HOMEWORK

No Model Grades Its Own Homework.

Claude, GitHub Copilot, OpenAI Codex, 200+ OpenRouter models, local Ollama, Kimi K2, and GLM — mix vendors so the model reviewing a security-sensitive diff is not the model that wrote it.

Claude GitHub Copilot OpenAI Codex OpenRouter (200+ models) Ollama (local) Kimi K2 GLM

Run a review panel: one vendor implements, a different vendor reviews the diff, a third judges the disagreement — before anything merges. Per-provider API keys, real-time cost and token tracking.

DEMO VS. PRODUCTION

Vibe Coding Gets You a Demo. Ptah Ships the SaaS.

Vibe-coding tools are excellent at turning a prompt into a working demo, fast. On every axis that separates a demo from a business, the demo holds a thin baseline — and Ptah keeps going.

Multi-Tenant IsolationPtah ships it
demo ceiling

demo — Tenant data isolation is whatever the generated scaffold happened to include — often nothing, until someone finds the leak.

ptah — Every tenant-isolation pattern that shipped before is recalled next session — an agent that already got it right doesn't re-guess it.

Billing CorrectnessPtah ships it
demo ceiling

demo — Billing gets wired once. Webhook retries, edge cases, and reconciliation are rarely touched again after the demo works.

ptah — A staffed team — architect, backend, tester — builds and reviews the billing integration the way it would for a paying customer, not a demo.

Security ReviewPtah ships it
demo ceiling

demo — No review step before the code ships — the model that wrote it is the only one that ever looked at it.

ptah — Cross-vendor review: a different model reviews the diff than the one that wrote it, before anything merges.

Architecture ConsistencyPtah ships it
demo ceiling

demo — Consistency degrades fast. Feature ten doesn't look like feature one, because nothing remembers feature one.

ptah — The same architectural decisions recalled every session, from feature one through feature fifty — Ptah keeps what it learns instead of starting cold.

Where each tool fits — an honest map

ideaproduction · feature 10 → 50
↑ the demo lands

Prototype generators

Vibe-coding tools — and a raw CLI agent for a single scripted CI task — are a fast way from an idea to a clickable demo. Genuinely the right call here; Ptah doesn't compete on demo speed, and doesn't pretend to.

Ptah — production team

For the moment after the demo lands: a codebase that has to isolate tenants, bill correctly, survive a review, and stay consistent past the tenth feature. A different job description — “production team,” not “prototype generator.”

PTAH BUILDERS — EARLY ADOPTER

Live Training Sessions

Weekly live sessions where we ship a real feature end-to-end — multi-tenant auth, billing integration, a security-review pass — and take questions on your build.

PRD-to-Production Curriculum

A structured path from a one-page PRD to a production-shaped SaaS: architecture decisions, tenant isolation, billing integration, and the review gates a solo prototype skips.

Member Skill Packs

Delivery patterns other Builders have already extracted and shared as SKILL.md packs — install the multi-tenant guard or billing webhook someone else already got right.

Priority Support

Direct access for build questions and architecture reviews, ahead of the public queue.

Every pattern a Builder extracts becomes one more thing the next build starts with — a library that grows, is shared, and compounds. That shared brain is the moat.
