Every prompt is a save point. A built-in security scanner catches the stuff that wrecks weekends. Undo is a time machine, not a hope. Ship weird ideas at 2am knowing you can rewind any prompt.
Not just autocomplete. A full pipeline of specialized agents, safety checks, persistent memory, and a canvas, all working together.
Before the AI touches a file it snapshots everything. After, you get a diff receipt. Undo AI and Restore buttons survive restarts, crashes, and the AI yeeting your codebase into the void.
A 20-point audit covering unprotected routes, hardcoded secrets, SQL injection, XSS sinks, command injection, and CVE matches. Run /vibe-scan before launch. Exact file, exact line, the fix.
Per-agent and shared project memory built on hybrid full-text plus vector search. Paste a URL once (docs, internal runbooks, your README) and the agent quotes the exact sentence that matters three weeks from now.
Intent is read before a single token is spent. Quick question? Minimal slice. Complex feature? Full context. Tool results the size of a novel get a tight preview and a pointer.
The planner picks the cheapest model that can do each step. Boilerplate goes to GPT-5 Nano. Auth, payments, crypto, and architecture sit on Sonnet 4.6 or Opus 4.7. Same output, fraction of the cost.
The reviewer leaves comments anchored to specific lines, visible as a soft overlay. Reply in context. The agent picks up the thread. Like Google Docs, not a terminal.
Infinite canvas for screens, flows, and sketches. Draw wireframes, convert to screens, connect with flow edges. A design wizard generates a token system your codebase can consume.
Every built-in behavior lives in a Markdown file. Override any of it by dropping your own into .architect/skills/. Skills auto-activate on file patterns.
List your MCP servers once. They appear as first-class tools in every agent. Connections stay alive for the whole session.
Bring your own Anthropic, OpenAI, or OpenRouter key on any tier and pay provider rates, no Decalyst markup. Your subscription still works, credits still track for visibility, power users escape the toll booth.
Detects your project type, runs install + build, fixes failures automatically. Live preview in the IDE. Download ZIP, push to GitHub, or export as Docker. One button each.
Invite via P2P link, no login required. You both see the AI work as it happens. Hand off mid-feature without losing context. End-to-end encrypted. Available on every tier.
Not one model. A chain of specialists, each owning their domain, each with a written persona you can read and override.
Memory Keeper feeds context throughout. Debugger runs on-demand when tests fail.
| Agent | Role | Default model | What they refuse |
|---|---|---|---|
Chuck Sr. PM | Planner - Reads your files, breaks tasks into atomic steps, creates file manifests, assigns workers, tracks dependencies, flags scope creep. | nemotron-120b | Writing code, planning only |
Aria Principal Engineer | Designer - Owns architecture, DESIGN.md tokens, system boundaries, database shape, API contracts, and escalation rules. Runs the design interview before any implementation starts. | nemotron-120b→sonnet-4-6 | Skipping the design interview |
Nova Coder | Coding Swarm - Scaffolds structure, fills logic, and escalates on auth, payments, and repeated failures. Three tiers, one agent. | Over-architecting, escalates when the plan is wrong | |
Hawk Eng Manager | Integration Reviewer - Reads all generated files together, checks imports, exports, and contracts, finds mismatches, verifies file responsibilities match the plan. Produces repair tasks. | nemotron-120b→sonnet-4-6 | Writing code, review and repair tasks only |
Vex Red Team | Security Scanner - OWASP audit, auth bypass checks, injection risks, hardcoded secrets, unsafe crypto, CVE/GHSA triage, tenant isolation, data leakage. | sonnet-4-6→opus-4-7 | Signing off without verification |
Lens Protocol Droid | Debugger - Takes failing tests, build logs, and runtime errors. Finds root cause, forms hypotheses, writes the failing test first, then patches the smallest fix. | codex→sonnet-4-6 | Papering over symptoms |
Echo Chief of Staff | Memory Keeper - Tracks prior design decisions, superseded choices, repo conventions, and active constraints. Feeds only relevant context back to Chuck. | gpt-5-nano→nemotron-120b | Inventing memories |
Patch Release Captain | Final Gatekeeper - Last pass before changes land. Checks tests, scope, risky files, security flags, migrations, rollback notes, and whether escalation was required. | sonnet-4-6 | Approving scope creep or unresolved security flags |
All agents have written personas readable in Settings > Agent Identities. Override any by dropping a file into .architect/agents/.
Every feature ships on every tier. Tiers only change how many credits you get. 1 credit equals $0.001 of AI cost at the provider. $1 in extra top-ups buys 500 credits, a flat 2x markup. BYOK is zero markup on every tier.
Start free. No card required. The full pipeline, the full safety net, the full agent team, from the first prompt.
