Your projects, agents, and knowledge live on your Mac — in a single encrypted database that never leaves your machine.
Privacy is architecture, not policy.
Your code is in one place. Your chats in another. Tasks in a third. Notes in a fourth. Every tool has a piece. None has the picture.
Every session starts blank. Your AI doesn't remember yesterday's breakthrough, last week's architecture decision, or the dead end you spent three hours proving.
What does your AI actually know right now? How close is it to forgetting? You can't see it. You can't control it. You just hope.
Is it running? What's it doing? Did it finish? Agent execution is a black box. You launch it and pray.
Your Claude history dies in Claude. Your GPT history dies in GPT. A year of conversations, insights, and decisions — gone the moment you switch tools.
Every prompt, every file, every conversation — uploaded somewhere else. Indexed for "product improvement." Subpoenable. Breachable. Not yours in any meaningful sense.
Chat, code, terminal, tasks, notes, and agents — all in one view. No tab-switching. No context-switching. Everything your project needs, visible at once.
Widget-based dashboard with drag-and-drop layoutNot just "memory." Explicit crystallization of what matters — validated approaches, confirmed preferences, known dead ends — persisted as durable knowledge that survives every session.
episodic → crystal → parametricStructured agents with hierarchy, permissions, event triggers, cron schedules, and circuit breakers. See what's running. Control what it can do. Resume where it stopped.
Event-driven automation with real-time visibilityReopen a project and land exactly where you left off. Files, chats, tasks, layout, agent state — all restored. No reconstruction.
Crystallize meaningful outcomes into durable, scoped directives. Positive and negative knowledge that every future session inherits automatically.
Cron schedules, event listeners, webhooks, manual fire. Your agents run when something happens — not just when you remember to ask.
Full Model Context Protocol integration. Connect any MCP server — ours or third-party — and it just works. A growing catalog ships pre-loaded. No vendor lock-in.
Your repos. Your models. Your machine. Zero cloud dependency. No upload limits. No data leaving localhost. Full project indexing without API token constraints.
Pick a task. Pick a surface — chat, code, or agent. Launch. Your session inherits the project context, crystal memory, and instructions automatically. Plan to execution in one click.
| Krystalize | ChatGPT + Codex + VS Code | Claude.ai + Cursor | DIY Stack | |
|---|---|---|---|---|
| Context across surfaces | One workspace. Always connected. | Copy-paste between 3 apps. Hope you got it all. | Two tools. Two contexts. Manual sync. | You built the glue. You maintain the glue. |
| Memory after session death | Crystal Memory — explicit, scoped, durable | Gone. Start over. Re-explain. | Project files help. Compaction kills the rest. | Whatever you put in Notion manually. |
| Task → execution | Spawn into chat, code, or agent. One click. | Open the right tool. Paste context. Remember instructions. | Manually attach files. Re-state the goal. | Custom workflow for each handoff. |
| Connectors survive compaction | Always loaded. Always available. | N/A | Lost on compaction. "Wait, we had that tool?" | You wired it. You fix it when it breaks. |
| Your data stays local | Always. Zero cloud. | Scattered across OpenAI + Microsoft + ??? | Cloud + local. Two trust boundaries. | Probably 5 clouds. Maybe 6. |
| Background automation | Cron + event + webhook triggers | — | — | You built it. You're on-call for it. |
| What you're juggling | What breaks | With Krystalize | |
|---|---|---|---|
| Home / Personal | Reminders + Todoist + Calendar + "I'll remember" | Nothing talks to each other. Your AI doesn't know your life. | One place for bills, groceries, kids' schedules, and side projects. Your AI knows it all. |
| Solo Dev | Claude.ai + Cursor + terminal + notes | Every session starts blank. You re-explain your architecture daily. | Your AI remembers yesterday. And last week. And the dead end from Tuesday. |
| Startup Founder | ChatGPT + Slack + Linear + 47 browser tabs | Context switches between strategy, code, hiring, AND personal life. | Business and personal in one brain. Investor deck to grocery list without losing your place. |
| Freelancer / Agency | Multiple clients × multiple repos × multiple Slacks | Every client switch costs 20 minutes of "where was I?" | Persistent workspaces per client. Switch instantly. Zero reconstruction. |
| Finance | Copilot + Excel + compliance docs + email | AI forgets last quarter's analysis. Sensitive data in the cloud. | Local-first isn't a feature — it's compliance. Historical context that compounds. |
We're opening early access to engineers, founders, and power users who are tired of starting from zero. Get in early. Shape what comes next.
Local-first. Open protocol. No data leaves your machine. Ever.
