Fulcra + ChatGPT
Step 0 for using ChatGPT.
Make ChatGPT yours.
ChatGPT does the reasoning but Fulcra gives it personal context about you, your work, and your world, so you can explain less and get better results.

ChatGPT can wake up knowing what changed, record what matters, and work from the same accumulated context as the rest of your agents. Whatever ChatGPT makes and writes back stays in a personal context lake that you control, rather than being trapped inside one AI product.

One personal context lake, every source you choose

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.

Problem
Most agents are brilliant strangers.

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.
Solution
One context for every agent you use.

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.

More context makes your agents more useful

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.

Agent memories, actions, and loops

Capture what agents remember, what they do, and the recurring workflows that turn context into useful follow-through.

Shared agent context

You can use Fulcra as a home for everything your agents need to see, store, remember, or tell another agent.

App and device data

Add any connector and bring app, device, and tool data into one shared context layer.

Bring any data

Context makes getting your data in one place easy. Events, notes, location, health, experiences, experiments, etc.

Everything ChatGPT is missing
Always current

Fulcra reads live data, not a stale snapshot. Every query reflects what's true right now meaning your latest sleep score, your next meeting, today's load.

200+ sources, one read

Google Calendar, Gmail, Apple Health, Oura, Whoop, Garmin, Dexcom, location, and more collapsed into a single query ChatGPT can act on.

Portable

Your context isn't locked to one ChatGPT project or one AI. Plug Fulcra in once, query it from anywhere. When you switch agents or switch models, your context comes with you.

Token-efficient by design

Real-world state lives outside the context window meaning ChatGPT reads only what changed, not your full history every prompt. That means that you are paying tokens for reasoning, not repetition.

You control it all

Fulcra has per-agent scoped tokens, a full read log, and one-tap revoke. Letting an AI know you should be a two-way door: grant access, revoke it, change agents, keep the context. You only share what you choose.

Context, not clutter

Fulcra scopes and normalizes your data before it reaches ChatGPT, so that ChatGPT gets the right signal at the right moment, not a wall of raw data.

Real things ChatGPT can do when it knows your world

Once Fulcra is connected, ChatGPT isn't just a brilliant stranger. It becomes your agent, with real situational awareness of your life and work.

Morning briefing that actually knows you

"How should I approach today?" — ChatGPT checks your sleep score, your calendar density, your energy trend, and tells you exactly what to protect and what to push.

Just-in-time meeting prep

Before your next call, ChatGPT pulls the attendee context, your last interaction, and what's changed since, without you doing any of the digging.

Health-aware productivity coaching

ChatGPT sees your recovery data alongside your task list. It can tell you when to push and when to protect, like a longevity doc on call.

Context that survives model swaps

Switch from ChatGPT to Claude, spin up a new Project, or move to a different app entirely and Fulcra carries everything over. Switch tools without starting over.

Your context belongs to you

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.
