Soul Alchemy vs ChatGPT Memory vs Claude Projects
Three tools claim to solve the same problem: making AI remember who you are. But they work in fundamentally different ways, cost different amounts, and — most importantly — one lets you own your data while the others don't.
Here's an honest breakdown.
The Comparison at a Glance
| Feature | ChatGPT Memory | Claude Projects | Soul Alchemy |
|---|---|---|---|
| How it works | Auto-stores facts from conversations | You write custom instructions per project | Generates identity files from your writing |
| Portable | No — locked in OpenAI | No — locked in Anthropic | Yes — plain text files, any AI |
| What it captures | Bullet-point facts | Your instructions (manual) | Full identity: values, style, personality |
| Cross-platform | ChatGPT only | Claude only | ChatGPT, Claude, Gemini, Llama, any AI |
| You control it | Can delete items | You write it yourself | You own the files |
| Pricing | Included in Plus ($20/mo) | Included in Pro ($20/mo) | One-time purchase |
| Survives platform switch | No | No | Yes |
ChatGPT Memory: Convenient, But Fragile
ChatGPT's Memory feature automatically picks up facts from your conversations. It might store "User is a product manager" or "User prefers concise answers."
What it does well: You don't have to do anything. It works in the background. For casual users, this is fine.
Where it breaks:
- It stores fragments, not identity. It knows your job title but not how you think.
- New conversations still start mostly from zero — Memory fills in scraps, not context.
- You can't export it. Switch to Claude? Start over.
- OpenAI decides what to remember. You review and delete, but you don't create.
Claude Projects: Powerful, But Manual
Claude lets you create Projects with custom instructions. You can write detailed context about yourself, your work, your preferences.
What it does well: You're in control. You write the instructions. Claude follows them precisely. For power users with specific workflows, this is excellent.
Where it breaks:
- You have to write everything yourself — most people don't know how to articulate their own identity.
- It's project-scoped, not identity-scoped. Your "work" project doesn't know your "personal" context.
- Locked inside Anthropic. Switch to ChatGPT or Gemini? Rewrite everything.
- No way to auto-generate from your existing writing.
Soul Alchemy: Portable Identity You Own
Soul Alchemy takes a different approach entirely. You paste your own writing — journals, emails, chat logs, notes — and it generates two files:
- SOUL.md — your identity archive, extracted from your actual words
- MEMORY.md — structured memory any AI can parse instantly
What it does well:
- Works with any AI — ChatGPT, Claude, Gemini, local models, future platforms
- Generated from your real writing, not your self-description (which is always incomplete)
- You own the files. Plain text. Store them anywhere. Share with any AI you choose.
- One-time purchase — no subscription
Where it breaks:
- Requires you to paste your writing in — not automatic
- You need to manually attach the files to new AI conversations
- No auto-update as you change over time (re-generate periodically)
So Which Should You Use?
Use ChatGPT Memory if:
You only use ChatGPT and want zero-effort convenience. You're okay with OpenAI deciding what matters about you.
Use Claude Projects if:
You're a power user with specific workflows. You can articulate exactly what you want Claude to know. You don't need cross-platform portability.
Use Soul Alchemy if:
You use multiple AI platforms. You want your identity to be portable. You want it generated from your real writing, not your best guess about yourself. You want to own your data — not rent it from a platform.
The question isn't which AI remembers you best. It's whether your identity belongs to you or to a platform.
