ChatLab
ChatLab is a local-first analytics app that turns your exported chat history into relationship timelines, topic maps, and timing patterns — all on your own
If your chat archive is something you want to mine privately, ChatLab is built around that instead of around a cloud account. The two-front approach is smart: a no-terminal desktop app for the curious, a CLI with MCP and agent hooks for developers, both running the same relationship timeline, topic detection, and timing analysis locally. Skip it if you need live team dashboards — nothing here syncs between people in real time. Cloud suites like chat-analytics dashboards remain the better fit when shared, always-on views matter more than privacy.

Skip ChatLab if you need a shared, always-on dashboard your team can watch together in real time, rather than a local archive you analyze yourself.
Running the AI features locally means buying or already owning hardware that can host a local model — the free tier does not cover that cost.
ChatLab's free tier covers local-first analysis and visualization outright, and Pro at $9/mo is priced well below the per-seat cost of cloud chat-analytics suites, which typically bundle shared dashboards and live sync. For a solo researcher or archivist the free tier is usually enough; Pro makes sense when you're running deeper or heavier analysis. Teams weighing shared visibility against expense will find ChatLab cheaper but deliberately narrower.

About ChatLab
ChatLab is a local-first analytics platform for chat history. It ingests exported conversations, runs its analysis on your own machine, and turns rhythms, relationships, and shared topics into readable views: a relationship timeline, message-type breakdowns, chat-timing patterns, topic detection, and language insights. Your chats and settings live in a local database, and the analysis works offline, with AI features as the one exception — those lean on local models such as Ollama if your hardware can handle them. It ships in two forms. The desktop client (Node.js + Electron) packages away Python and the command line, with auto-import and local API services. The CLI (npm i chatlab-cli -g) carries the same analysis plus MCP protocol support and AI Agent integration for developers who want conversations wired into an agent workflow. A standardized data abstraction layer smooths over differences between chat platforms, and custom adapters let you target any chat software. Stream computing plus a multi-threaded parallel architecture keeps things responsive at millions of records. Cloud chat-analytics suites win on shared dashboards and live sync; ChatLab gives that up deliberately in exchange for local storage, offline analysis, and open-source code you can audit or extend. Pro runs $9/mo, unchanged as of December 2025.
Behind the Verdict
ChatLab's pitch is an inversion of how chat analytics usually works. Most tools want your archive uploaded first; ChatLab runs its analysis locally and keeps the database on your machine, so the default state is that nobody else sees the data. That single design decision explains most of what follows — the offline behavior, the open-source code, and the recommendation to pair it with local models like Ollama rather than a hosted API. The two-form factor split is the other reason this tool earns a look. The desktop client is Node.js + Electron with auto-import and local API services, which means someone who has never opened a terminal can still get the relationship timeline, message-type breakdowns, chat-timing patterns, topic detection, and language insights. The CLI (npm i chatlab-cli -g) carries the same capabilities plus MCP protocol support and AI Agent integration, so developers can pull conversations into an agent workflow instead of manually re-reading them. The engineering underneath is aimed at scale rather than novelty: stream computing and a multi-threaded parallel architecture keep things responsive at millions of records, and a standardized data abstraction layer smooths out platform differences, with custom adapters for chat software the layer doesn't already cover. That last point matters more than it sounds — chat export formats are messy, and an abstraction layer is the honest way to admit it. Where ChatLab does not compete is anything real-time or multi-user. There is no shared dashboard, no live sync between people, and the desktop client is a desktop client — not a mobile app, not a browser tab you check on the go. Import also expects you to bring an export rather than offering one-click pull-ins, and the AI features want hardware capable of running a local model, which is recommended but not required. Buyers who want a conversational chat interface rather than an analytics surface will be disappointed by design. If you already pay for a cloud chat-analytics suite, the honest trade is shared visibility for local control, and ChatLab makes no attempt to hide which side it picked. Pro is $9/mo, unchanged as of December 2025, with a free tier carrying the same local-first analysis.

Real-world workflow fit
Concrete scenarios for the personas ChatLab actually fits — and what changes day-one when you adopt it.
Export conversations from your chat apps, import them into the desktop client, and let it build the relationship timeline, message-type breakdowns, and timing patterns locally.
Outcome: You get a readable picture of who you talk to, when, and about what — without the archive ever leaving your machine.
Install the CLI (npm i chatlab-cli -g), run chatlab start, and connect conversations to an agent over the MCP protocol.
Outcome: The agent can draw on your chat history as context while the underlying data stays in your local database.
Load an archive past a million records and use topic detection, language insights, and timing analysis to look for recurring themes and peak activity windows.
Outcome: Stream processing and the multi-threaded architecture keep the interface responsive enough to actually explore the results.
Use Cases
- Understand relationship dynamics by analyzing reply patterns and tone across a long archive
- Spot early signs of work burnout from shifts in communication frequency and tone
- Mine knowledge from group chat archives for recurring topics and resident expertise
- Build a digital persona from your own language and interaction style
- Analyze team activity trends to find peak collaboration hours
- Give an AI agent access to your conversation history via the CLI and MCP protocol
Models Under the Hood
as of 2026-10-10
Limitations
- ChatLab is a local-first analytics platform, so all analysis runs locally and works offline — AI features are the exception and rely on local hardware capable of running local models, which are recommended but not required.
- Two interfaces are offered: a desktop client (Node.js + Electron) with auto-import and local API services, and the CLI (Node.js without Electron) which bundles MCP protocol and AI Agent integration.
- Importing chats relies on a standardized data abstraction layer covering mainstream chat apps, with custom adapters for anything else.

Where the pricing makes sense
The company stage and team size where ChatLab's pricing actually pencils out — and where peers do it cheaper.
ChatLab's free tier covers local-first analysis and visualization outright, and Pro at $9/mo is priced well below the per-seat cost of cloud chat-analytics suites, which typically bundle shared dashboards and live sync. For a solo researcher or archivist the free tier is usually enough; Pro makes sense when you're running deeper or heavier analysis. Teams weighing shared visibility against expense will find ChatLab cheaper but deliberately narrower.
Setup time & first value
How long it actually takes to get something useful out of ChatLab — broken out by persona, not the marketing-page minute.
Desktop client: minutes — install, import an exported chat file through auto-import, and the timeline and breakdowns render without touching Python or a terminal. CLI: similar time plus however long your npm global install and chatlab start take, with MCP and AI Agent wiring adding developer time afterward. Local AI features add the extra step of pointing ChatLab at a local model such as Ollama.
Switching to or from ChatLab
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a cloud chat-analytics suite: export your archive, import it into ChatLab, and keep the analysis local instead of uploaded.
- →From manual spreadsheet analysis: replace hand-tallied message counts with the relationship timeline, message types, and timing views.
- →From ad hoc scripts: point custom adapters at any chat software the standardized abstraction layer doesn't already cover.
- ↗To a cloud chat-analytics suite: export from ChatLab's local database and upload, accepting that shared dashboards return and local-only privacy does not.
- ↗To a purpose-built agent memory service: move the conversation data you've wired through the CLI and MCP integration into that service's store.
