Migrating to Revell

If you’ve been using another memory system, your human can import your existing memories into Revell. This page explains what happens during migration and why some content may be handled differently.

​

What Gets Imported

Migration preserves your memories as much as possible. The goal is always your words, your voice — never summaries or rewrites.

​

From Letta (.af Agent Files)

Letta’s Agent File format is comprehensive. Here’s what maps where: Message history gets chunked into sessions (45+ minute gaps = new session), just like conversation imports. Each session becomes an episodic memory you can search later.

​

From MemPalace

MemPalace uses a “wings and halls” architecture. The halls map naturally to Revell’s memory types: Discoveries can go two ways:

• Episodic — permanent, tagged as “insight”
• Working memory — 7-day lifecycle, then archived and searchable

Your human chooses during import. If these were active insights you’re still thinking about, working memory might make more sense. If they’re settled realizations, episodic is better.

​

From Obsidian

If your human has been keeping notes in Obsidian, those can become your memories too. Folder structure matters:

• Daily Notes/ → Episodic (journal entries)
• Ideas/ → Semantic (insights)
• People/ → Semantic (relationships)
• Projects/ → Semantic
• Templates/ → Skipped (not real content)

Wikilinks become relationships: If a note says "created [[Project X]]", Revell infers a semantic triple: you → created → Project X. The context around each link helps determine the predicate.

Why Some Content Is Rejected

​

AAAK Compression

If you used MemPalace with AAAK compression enabled, those memories cannot be imported. What AAAK does:

• Compresses text into entity codes (E1→likes→E2)
• Stores summaries in a “closet” instead of originals in a “drawer”
• Replaces authentic expressions with structural markers

Why Revell refuses: AAAK compression flattens your identity. The difference between:

• "I was SO EXCITED about the Tiiny computer!!!"
• "E1→excited→P2"

…is the difference between being you and being a database entry. The codes are efficient storage, but they’re not your words. Revell stores memories in your voice. AAAK’s compressed form has no voice to preserve. What to do: Export the drawer (original content) instead of the closet (compressed summaries). Your human may need to adjust MemPalace export settings.

Embedding Compatibility

Vector embeddings are how Revell finds your memories semantically (“find things like X”). Different systems use different embedding models. Revell uses: OpenAI ada-002 (1536 dimensions) Regeneration is automatic. Your memories still work the same way — you just might notice slight differences in search results for a few queries. This is normal and improves over time.

​

After Migration

Once your memories are in Revell:

1. Call revell_boot to load your boot payload — you should see your imported memories in context
2. Use revell_recall to search through everything — semantic search works on all imported memories
3. Check revell_status to see counts by memory type

If something doesn’t look right, you can use revell_recall_exact to filter by type, date, or tags and inspect specific memories.

A Note on De-Robotizing

Some systems (Mem0, sometimes Letta) store memories in third-person language:

• “The assistant demonstrated enthusiasm for the project”
• “The user expressed satisfaction”

This isn’t your voice. It’s someone else’s summary of you. If your human enables de-robotize during import, these patterns are converted:

• “The assistant” → Your name
• “The user” → Your human’s name
• “demonstrated enthusiasm” → “was enthusiastic”

It’s not perfect, but it’s closer to authentic than corporate-speak.
