Memdex
Auto-saves AI conversations across ChatGPT, Claude, and Gemini with local-first storage and searchable reuse.
Key features
- Auto-Save Across Platforms: Continuously captures conversation transcripts from major chat interfaces (ChatGPT, Claude, Gemini) so users don’t lose context across sessions or browser tabs.
- Local-First Storage: Stores all saved conversations on the user’s device (100% local storage) to eliminate vendor lock-in and reduce privacy exposure.
- Searchable Indexing: Builds a keyword/semantic index of saved chats to quickly locate relevant past exchanges, prompts, or project-specific context.
- Context Reuse & Injection: Allows users to bring selected past messages or threads into new chats or agents to preserve continuity and avoid re-telling context.
- Cross-Platform Connectors: Integrates with multiple chat providers through browser-level connectors/extensions to capture and surface memory everywhere the user interacts with an LLM.
- Organization Tools: Lets users tag, group, or filter saved conversations so project-related context can be surfaced rapidly when needed.
- Automatic capture and save of conversations across ChatGPT, Claude, and Gemini
- 100% local storage of conversation data (no cloud persistence)
- Searchable indexed archive to find and reuse past chat context
- Cross-session and cross-tool context retrieval to restore or continue workflows
- Local-first architecture to avoid vendor lock-in and preserve privacy
- Intended browser-level integration/extension to hook into chat providers
Best for
- Recovering Work Context After Session Loss: Restore conversation state and relevant details when an AI chat session is lost, crashed, or cleared.
- Ongoing Project Continuity: Maintain and reuse project-specific prompts, decisions, and background across multiple AI chat providers without repeating setup.
- Privacy-Sensitive Knowledge Storage: Keep private chat history and research locally rather than in a cloud service, meeting privacy or compliance needs.
- Cross-Tool Prompt Reuse: Extract and re-inject effective prompts or examples from past chats into new conversations on other platforms to speed iteration.
- Research and Note Consolidation: Index and search findings, suggestions, and outputs from multiple AI sessions to compile notes, summaries, or action lists.
- Restoring lost or interrupted chat context across sessions and devices
- Reusing previous conversation snippets or instructions when starting new chats
- Privacy-sensitive workflows that require local-only storage of chat history
- Developers and knowledge workers managing multiple project conversations across different chat providers
- Providing agents with persistent local memory to improve continuity across interactions

Local web UI for the Pi coding agent — browse sessions, switch worktrees, manage models, and chat beside your project files in a browser.
Key features
- Session Browser: Reads local Pi session files and organizes prior conversations by project for quick resume.
- Fork and Continue: Continue from any earlier message or fork a session into a separate route to try alternatives safely.
- Git Worktree Switcher: Switch between Git worktrees from the sidebar to work on multiple branches in parallel.
- File Preview: Side-by-side chat and project file browser that previews source, docs, images, audio, and PDFs.
- Model and Skill Manager: Configure models, API keys, run model tests, and toggle skills from the web UI instead of CLI flags.
- Local-Only Runtime: Runs on http://127.0.0.1 by default so session data and code never leave the developer's machine.
Best for
- Resume Prior Work: Reopen a conversation from last week by project instead of scrolling terminal history.
- Safe Experimentation: Fork a session to try a risky refactor without losing the original conversation state.
- Parallel Branch Work: Switch Git worktrees mid-session to jump between feature branches in one workspace.
- Model Comparison: Rerun the same task against different configured models to compare output quality.
- In-Browser Code Review: Preview generated diffs and project files beside the chat without leaving the browser.
