The problem with AI today

No memory

Every conversation starts from zero. You re-explain your portfolio, your family, your constraints — every single time.

Stale context

Tools that do remember use three-month-old data confidently. Outdated advice is worse than no advice.

Locked to one model

Your context is trapped inside ChatGPT or Claude. Switch models and your history disappears.

Fidant.AI solves this

One memory layer. Every model. Every conversation.

Remembers everything

Identity, businesses, health, decisions

Updates automatically

Context sharpens after every conversation

Works with every model

Claude, GPT-4o, Gemini — your pick

Health tracking

Upload lab results and Apple Health data. Track biomarkers with automatic unit conversion.

Built-in anti-sycophancy

Fidant pushes back on bad ideas. Constraints and decision history keep the AI honest.

Decision memory

Past decisions, priorities, and constraints are always in context. No conflicting advice across sessions.

Privacy by architecture

User-controlled memory — your context files live on your Google Drive, not our servers

Source transparency — every remembered fact links to the message, note, or document it came from

Scoped access — we use Google's drive.file scope, so we only see the files Fidant itself creates

We never train models on your data

Sovereign Trust Gate (coming soon) — a stricter mode for keys we should never hold

Common questions

Where does my data live?: On your Google Drive. Fidant reads and writes a single folder. You can export or revoke access any time.
Can I downgrade or cancel?: Yes. Self-serve from your billing portal — Stripe handles the prorating.
What's the difference between Pro and Sovereign?: Pro is built for one executive working solo. Sovereign supports family-office workflows — multiple principals, shared memory across advisors, and a quarterly review with the founding team.
