ChatFolders is a browser extension built by a solo indie developer that adds folders, color-coded tags, bookmarks, and auto-sort rules to the four major AI chat interfaces: ChatGPT, Claude, Gemini, and Grok. All data is stored locally in your browser — no accounts, no cloud sync, no server-side storage. The cross-platform coverage from a single extension is the headline feature. The extension fills a genuine organizational gap that all major AI chat products have been slow to address. ChatGPT has Projects but they're limited. Claude's sidebar is essentially a flat list. Gemini has folders but only within its own ecosystem. Grok has nothing. ChatFolders applies a consistent organizational layer across all four interfaces simultaneously, which means you can apply the same tagging taxonomy regardless of which model you're using for a given task. The local-first architecture is a deliberate privacy choice. Given how sensitive the contents of AI chat conversations can be — from business strategy to personal health — an extension that explicitly stores nothing server-side and requires no authentication is meaningfully different from cloud-synced alternatives. The solo indie origin makes this a genuine labor-of-love project rather than a VC-funded bet. Already seeing organic traction from power users who have hundreds of conversations with no way to find anything.

Mike
Open-source legal AI that reads docs, cites verbatim, and drafts contracts

Mike is an open-source legal AI platform built as a direct alternative to Harvey and Legora — without the vendor lock-in or per-seat pricing. It connects to Claude or Gemini via your own API keys and gives solo practitioners and small firms the same document review, contract drafting, and workflow automation capabilities that enterprise legal tools charge thousands for. The platform organizes work into matter-scoped Projects — persistent workspaces where documents stay contextually linked across sessions. Its Tabular Review feature extracts structured data from multiple documents into a spreadsheet view, with every cell backed by a verbatim citation you can click to verify. Workflows layer on top for repeatable tasks like credit agreement summaries and change-of-control reviews. Mike is built by Will Chen and is self-hostable or available as a cloud product. The fundamental pricing model is radical: you pay only your Claude or Gemini API costs. No license fees, no per-seat pricing. For small firms doing high-volume document review, the economics are dramatically better than any SaaS alternative at $500–$2,000/user/month.
Reviewer scorecard
“The cross-platform angle is what makes this actually useful. I use different models for different tasks — Claude for writing, ChatGPT for code, Gemini for research — and having one organizational system that works across all of them without switching contexts is a genuine quality-of-life improvement. Local-first is also the right call for professional conversations.”
“Self-hosted legal AI that runs on your own Claude or Gemini API key is genuinely clever — the pricing model alone makes this worth exploring. The codebase is clean and the tabular citation view is the kind of UX detail that shows someone actually thought about the legal workflow. Deploy this for any firm that's been priced out of Harvey.”
“Browser extensions for major AI platforms are inherently fragile — one UI update from OpenAI or Anthropic breaks everything until the solo developer finds time to patch it. The local-only storage also means your organizational system doesn't follow you to a new computer. This solves a real problem but in a brittle, unscalable way.”
“Solo dev projects in legal tech carry serious liability risk — if the model hallucinates a clause or misses a citation, the consequences aren't a bad tweet, they're malpractice exposure. Until this has real-world usage data from actual attorneys and independent security audits, enterprise law firms should stay cautious. Also, Claude Sonnet or Gemini Flash are not the same as GPT-5.5 fine-tuned on case law.”
“The fact that someone had to build this as a browser extension is the real story: none of the major AI companies have prioritized knowledge management for power users. ChatFolders is filling a gap that should have been filled by product teams months ago. Either someone acqui-hires this developer, or the major platforms ship native folder systems within the year.”
“Open-source legal AI is the first credible wedge against the Harvey monopoly on AI-native law. When every solo practitioner and boutique firm can deploy their own matter-scoped AI workspace for free, the power dynamic in legal tech shifts permanently. Mike is the kind of project that looks small today and reshapes an industry in five years.”
“For content creators juggling project briefs, brand voice docs, and campaign conversations across multiple AI tools, this is genuinely useful. Color-coded folders alone is worth the install — visual organization of a chaotic sidebar has an immediate quality-of-life impact. The auto-sort rules could save hours per week for heavy users.”
“The tabular review UI is genuinely beautiful for a developer-built open source project — it solves the 'show your work' problem that makes lawyers distrust AI outputs. If the UX holds up under real document loads, this is the design template for AI tools in trust-sensitive industries.”
