Hermes can wake up knowing what changed, record what matters, and work from the same accumulated context as the rest of your agents. Whatever Hermes makes and writes back stays in a personal context lake that you control, rather than being trapped inside one AI product.
Fulcra is a user owned context backend. Under the hood, it is a data platform. What accumulates for each owner is a personal context lake: a mix of structured, semi-structured, and unstructured data from many sources, agents, and applications over time.
Connect the sources you choose:
data feeds you want your agents working from,
exports from systems you don't want to give them the passwords to,
giant time series,
continuously updating event logs,
snapshots of entire folders,
updates from your other agents.
Get started with Fulcra at https://github.com/fulcradynamics/agent-skills/They don't know what changed since your last conversation, and they can't build on what another agent learned.
Scattered across apps. What each agent learns stays trapped inside one app, one agent, or one model provider. Each system keeps its fragment separate.
Updates you can't see or steer. What an agent knows about you changes without you. You don't see when, or why, it updates.
Start over with every switch. Every agent keeps its own private record of you. Switch tools, and the relationship starts over.
Fulcra brings real-world data, recorded knowledge, files, and agent work into one context you own — and your agents connect to it.
One context, every agent. Instead of every agent building its own private record of who you are, your agents read from and write to one context you control.
Readable and controllable. Agents read from it, contribute to it, and learn from it. You can see what they know, trace how they learned it, and revoke access whenever you want.
It travels with you. Carry your context across AI products. Change agents, change models — and never have to start over.
Fulcra gives agents a shared place to access real-world data, record what matters, and discover what's new on every loop — so they understand what is happening, what changed, and what might help next.
Capture what agents remember, what they do, and the recurring workflows that turn context into useful follow-through.
You can use Fulcra as a home for everything your agents need to see, store, remember, or tell another agent.
Add any connector and bring app, device, and tool data into one shared context layer.
Context makes getting your data in one place easy. Events, notes, location, health, experiences, experiments, etc.
Check our Fulcra team space — did any of my other agents leave work or notes since your last loop? Post what you finished today so they can build on it.
Example outputYour research agent posted 3 sources at 2am and flagged one for review. I've queued your draft as a task for the writing agent, with scoped context — just the outline, not your whole lake.
Create a tracker for my side project: log each session with what shipped and how it felt, then build me a live dashboard of momentum this month.
Example outputTracker schema created; 9 sessions logged. Your dashboard shows Tuesday sessions ship 2× more — want me to guard Tuesday mornings on your calendar?
Check Fulcra for what changed since your last loop — calendar, messages, work from my other agents — and give me the 60-second version.
Example outputSince 11pm: your flight moved 40 minutes, the deploy agent shipped and left release notes, and two invoices arrived. One thing needs you: the contract redline.

Get started with Fulcra at https://github.com/fulcradynamics/agent-skills/Google Calendar, Apple Calendar, Apple Health, Garmin, Oura, Whoop, Dexcom, nutrition apps, and your location throughout the day. Everything your wearables and apps already create, unified into a single source of truth your Hermes agent can query. Install the Fulcra skill, connect your sources once, and your agent has access without account logins or manual context-pasting.
Hermes's MEMORY.md holds what your agent has learned: your preferences, your projects, your environment. Fulcra holds what's true about your life right now — your sleep stats, your HRV, your calendar load, your current medications. Context means more than memory, and these change daily; Fulcra gives your agent a place to query them on demand, beside Hermes's own memory rather than in place of it.
Hermes's MEMORY.md is capped at ~2,200 characters. Real-world state — biometrics, calendar, location — doesn't belong there. It's too large, it changes every day, and it ages out the moment it's written. Query it live from Fulcra instead, scoped to what the current task needs, and keep your memory focused on what it's designed for: durable facts about your environment and preferences.
Hermes writes and edits its own skills through use. Fulcra is a ground truth reference that is immune to drift, making it reliable data you can trust, no matter how much your agent evolves.
When you wire Fulcra into your Hermes build, each subagent can query the same source at call time and pull only what's relevant to its task. A research subagent gets your current focus window and timezone to scope its output. A scheduling subagent gets your calendar load and sleep quality to protect your afternoon. Both query the same Fulcra snapshot. Neither gets the other's data.
See how Hermes handles subagent delegation:
Sharing context with an AI — letting it know about you, your work, and your world — should be a two-way door. Grant access. Revoke it. Change agents. Keep the context. Keep what your agents make.
Fulcra was built by founders with 15 years in security infrastructure including HUMAN, Veracode, Verisign. Your vault is encrypted at rest and in transit, with per-agent scoped access and a full audit log on every read.
