Pro

The free core snapshots your project. Pro gives your agents continuity (memory, session history, and cross-model judgment) while keeping everything as local as the core.

What Pro adds

Session connectors

Digests of your recent sessions from eight tools (Claude Code, Cursor, Codex CLI, OpenCode, Gemini CLI, Aider, OpenClaw, and Hermes Agent) flow into the snapshot automatically, so a fresh agent picks up where the previous one left off, even when that was a different tool entirely. Best-effort, read-only, reads a copy; see Connectors for exactly what each one reads.

Pro sells the invisible version of this. The universal fallback, agent-assisted ingest via the ingest_context tool, is free core and covers any harness with one pasted prompt.

Encrypted memory

Cross-session memory your agents can write to and recall from, exposed as the remember, recall, and forget MCP tools. Content is AES-256-GCM encrypted at rest under ~/.ctxfile/, the key lives in your OS keychain, and every entry carries provenance: what wrote it, when, from what source. The dashboard's Memory view lists and deletes entries.

Multi-provider consult

The consult tool asks the same question to several models at once (Anthropic, any OpenAI-compatible endpoint, or local Ollama) over your live project context, and streams their answers side by side. Providers come from your consult.providers config; API keys are read from env vars you name, never stored.

Voice notes

The transcribe_voice tool runs whisper.cpp entirely on your machine, with a vocabulary built from your repo. Say the function name, get the function name, not a phonetic guess.

The exact tool registrations, feature gating, and schemas are on MCP surface.

Offline licensing

Your license is an Ed25519-signed key. Activation verifies the signature locally against a public key embedded in the binary. No phone-home, no activation server, no license check traffic, ever. If a license expires, a 14-day grace period keeps Pro features working while you renew.
