What is Conversation Archiving?

Conversation archiving is the systematic capture and storage of complete AI agent interactions, preserving the full context of each session including messages, metadata, attachments, and edit history. Unlike cloud-based chat interfaces where conversations are stored on vendor servers, local-first archiving gives you direct control over your data.

Archive vs. Export

Traditional Export (ChatGPT, Claude.ai):

Manual download process
Incomplete metadata
No continuous capture
One-time snapshots

Continuous Archiving (Memvault):

Automatic capture via hooks
Complete metadata preservation
Real-time updates
Immutable record keeping

Why Archive AI Conversations?

1. Knowledge Retention

AI conversations contain valuable intellectual property:

Decision Records: Why you chose specific approaches
Technical Context: Architecture discussions and trade-offs
Problem-Solving Process: How you arrived at solutions
Domain Knowledge: Learned facts and relationships

According to digital archiving best practices, capturing complete context—including metadata like timestamps, participants, and related files—is essential. Partial archiving creates gaps that undermine long-term value.

2. Cross-Session Continuity

Agents lose context between sessions. Archives enable:

Project History: Resume work weeks later with full context
Pattern Recognition: Identify recurring issues across sessions
Knowledge Transfer: Share context with team members
Learning Curves: Track how your AI usage evolves

3. Compliance and Audit Trails

For regulated industries or corporate environments:

Immutable Records: Conversations cannot be altered after creation
Complete Audit Trail: Every interaction timestamped and attributed
Data Sovereignty: Records stay on your infrastructure
Retention Policies: Implement your own deletion schedules

Research from Oracle on multi-tenant agent memory shows that proper memory management requires treating archives as first-class infrastructure with explicit lifecycle policies.

4. Search and Discovery

With archives indexed for full-text search using SQLite FTS5, you can:

Find conversations by keyword in milliseconds
Search across all agents and time periods
Discover related discussions automatically
Extract insights from conversation patterns

Real-world implementations report sub-10ms query times on thousands of conversations using FTS5's inverted index architecture.

How Memvault Captures Conversations

Hook-Based Architecture

Memvault uses event hooks integrated into your AI agent to capture conversations as they happen:

User Types Message
       ↓
Agent Receives (UserPromptSubmit hook fires)
       ↓
Memvault Captures Message
       ↓
Agent Responds
       ↓
Memvault Captures Response
       ↓
Archive Updated (atomic write)

Supported Agents

Claude Code

Claude Code is Anthropic's official CLI and desktop application. Hook integration:

Terminal Version:

json

// ~/.claude/settings.json
{
  "hooks": {
    "SessionStart": "memvault hook session-start",
    "UserPromptSubmit": "memvault hook user-prompt-submit"
  }
}

Desktop App: Same configuration file location on macOS, Windows, and Linux.

Codex

Codex by Anthropic provides similar hook capabilities:

json

{
  "hooks": {
    "onSessionStart": "memvault hook session-start --agent codex",
    "onUserPrompt": "memvault hook user-prompt-submit --agent codex"
  }
}

Future Support

OpenCode: Planned Q1 2027
Custom Agents: MCP-based agents can integrate via standard hooks

What Gets Captured

Each archived session contains:

1. Messages

Every user and assistant message, stored as individual JSON files:

json

{
  "version": "1.0",
  "role": "user",
  "content": "Implement a folder picker with native dialog support",
  "timestamp": "2026-10-15T08:23:45.123Z",
  "meta": {
    "model": "claude-opus-5-5",
    "tokens": {"input": 156, "output": 0}
  }
}

Individual file storage follows archiving best practices for append-only systems, ensuring data integrity and enabling concurrent access.

2. Session Metadata

json

{
  "id": "f75cb010b12a8eb0d7a057989cc3e16c",
  "agent": "claude",
  "native_id": "4b67a8e4-b697-4ede-a87f-c99f5b95da03",
  "title": "Folder Picker Implementation",
  "created": "2026-10-15T08:00:00Z",
  "updated": "2026-10-15T10:30:00Z",
  "message_count": 42,
  "model": "claude-opus-5-5"
}

3. Attachments

Files, images, and artifacts are stored alongside messages:

sessions/f75cb010.../
├── messages/
│   ├── 0001.json
│   ├── 0002.json
│   └── ...
├── attachments/
│   ├── screenshot.png
│   └── config.yaml
├── artifacts/
│   └── generated-code.tsx
└── meta.json

4. Edit History

When messages are edited, the full history is preserved:

json

{
  "original": "Implement basic picker",
  "edits": [
    {
      "timestamp": "2026-10-15T08:25:00Z",
      "content": "Implement native dialog picker"
    }
  ]
}

Storage Location

Default vault structure:

~/memvault/
├── sessions/           # All conversation archives
│   ├── abc123.../     # One directory per session
│   └── def456.../
└── .memvault/         # Internal data
    ├── db/            # Search indices
    └── logs/          # Application logs

Custom location:

bash

export MEMVAULT_HOME=/path/to/vault

Archiving Best Practices

1. Define Your Archiving Strategy

Following enterprise archiving guidelines, establish clear policies:

What to Archive:

✅ All development conversations
✅ Decision-making discussions
✅ Problem-solving sessions
✅ Learning interactions
❌ Test conversations (tag for cleanup)
❌ Accidental starts (delete immediately)

Retention Periods:

Active projects: Keep everything
Completed projects: Archive for 2+ years
Personal learning: Indefinite retention
Sensitive data: Implement deletion schedules

2. Implement the 3-2-1 Backup Rule

As recommended in digital archiving standards:

3 copies of your data
2 different storage media types
1 copy off-site

bash

# Primary: Your machine
~/memvault/

# Secondary: External drive
/Volumes/Backup/memvault/

# Off-site: Cloud sync
~/Dropbox/memvault/

Automated backup script:

bash

#!/bin/bash
# Daily backup to external drive
rsync -av --delete ~/memvault/ /Volumes/Backup/memvault/

# Weekly backup to NAS
rsync -av --delete ~/memvault/ nas.home:/backups/memvault/

3. Maintain Archive Integrity

Immutability: Never edit archived message files directly. The archive is the source of truth.

Verification: Periodically check archive integrity:

bash

# Verify file structure
memvault verify --check-integrity

# Rebuild search index if corruption detected
memvault index rebuild

Version Control: For critical projects, track archives in git:

bash

cd ~/memvault
git init
git add sessions/
git commit -m "Archive snapshot $(date +%Y-%m-%d)"

4. Optimize for Searchability

Enable fast retrieval using SQLite FTS5:

Index Optimization:

bash

# Rebuild index for better performance
memvault index rebuild

# Analyze index statistics
memvault index stats

According to SQLite FTS5 performance research, proper indexing reduces search time by 99.6% compared to traditional LIKE queries.

Query Performance:

Simple terms: <10ms
Multi-word queries: 20-50ms
Large archives (10,000+ sessions): 50-100ms

5. Secure Your Archives

File Permissions:

bash

chmod 700 ~/memvault/

Encryption at Rest:

macOS: Enable FileVault
Linux: Use LUKS
Windows: Enable BitLocker

Encryption in Transit (if syncing): All major sync tools encrypt by default:

iCloud: End-to-end encrypted
Dropbox: TLS 1.2+ in transit
Syncthing: TLS encrypted P2P

Managing Your Archives

Listing Sessions

bash

# List all sessions
memvault sessions list

# Filter by agent
memvault sessions list --agent claude

# Filter by date range
memvault sessions list --from 2026-10-01 --to 2026-10-15

# Sort by activity
memvault sessions list --sort updated

Reading Sessions

bash

# View session summary
memvault sessions read abc123

# Export to JSON
memvault sessions export abc123 --format json

# Export to Markdown
memvault sessions export abc123 --format markdown

Searching Archives

bash

# Simple search
memvault search "folder picker"

# Search with filters
memvault search "native dialog" --agent claude --from 2026-10-01

# Search with context
memvault search "implementation" --context 5

Cleaning Up

bash

# List test sessions
memvault sessions list --tag test

# Delete specific session
memvault sessions delete abc123

# Archive old sessions (move to separate directory)
memvault sessions archive --older-than 365d

Session Linking

Track relationships between conversations:

bash

# This session continues previous work
memvault sessions link \
  --from old-session \
  --to new-session \
  --type continuation

# This session branches from another
memvault sessions link \
  --from parent-session \
  --to branch-session \
  --type branch

Troubleshooting Common Issues

Hooks Not Firing

Symptom: No sessions being captured

Solutions:

Verify hook configuration:

bash

cat ~/.claude/settings.json | grep -A 2 hooks

Check memvault is in PATH:

bash

which memvault
# Should output: /usr/local/bin/memvault (or similar)

Test hook manually:

bash

echo '{"agent":"claude","native_id":"test"}' | \
  memvault hook session-start

Check agent logs:

bash

# Claude Code terminal logs
tail -f ~/.claude/logs/session.log

# Memvault logs
tail -f ~/.memvault/logs/hooks.log

Restart agent: Hooks only load at startup

Missing Messages

Symptom: Some messages not archived

Causes:

Hook fired before message fully processed
Disk full
Permission errors

Solutions:

bash

# Check disk space
df -h ~/memvault

# Check permissions
ls -la ~/memvault/sessions/

# Re-index to find orphaned messages
memvault index rebuild --scan-all

Search Not Finding Results

Symptom: Known conversations don't appear in search

Solutions:

Rebuild search index:

bash

memvault index rebuild

Check index status:

bash

memvault index stats

Verify FTS5 enabled:

bash

sqlite3 ~/.memvault/db/fts.db \
  "SELECT * FROM pragma_compile_options WHERE compile_options LIKE '%FTS5%';"

Performance Degradation

Symptom: Searches becoming slow

Causes:

Index fragmentation
Too many archived sessions
Concurrent access

Solutions:

bash

# Optimize database
memvault db optimize

# Archive old sessions
memvault sessions archive --older-than 365d --to ~/memvault-archive/

# Check database size
du -sh ~/.memvault/db/

Advanced Topics

Custom Archiving Scripts

Extend archiving with custom logic:

bash

#!/bin/bash
# Auto-tag sessions by content

memvault sessions list --format json | jq -r '.[] | .id' | while read session_id; do
  content=$(memvault sessions read "$session_id")
  
  if echo "$content" | grep -q "security"; then
    memvault sessions tag "$session_id" security
  fi
  
  if echo "$content" | grep -q "bug"; then
    memvault sessions tag "$session_id" bug-fix
  fi
done

Export for Analysis

Extract archives for external analysis:

bash

# Export all to JSON
memvault export --format json --to /tmp/export/

# Analyze with jq
find /tmp/export -name "*.json" | xargs jq '.messages[] | select(.role=="user") | .content' > user-prompts.txt

# Generate statistics
memvault stats --from 2026-01-01 --to 2026-12-31

Multi-Vault Setup

Separate archives by project or client:

bash

# Project A
export MEMVAULT_HOME=~/vaults/project-a
memvault serve --port 27961

# Project B
export MEMVAULT_HOME=~/vaults/project-b
memvault serve --port 27962
