Pros
  • One extension covers ChatGPT, Claude, Gemini, and Grok, so you keep the same folder tree and prompt library across models
  • Full-text search across message bodies fixes the single biggest gap in every native LLM chat UI
  • Multi-format export (TXT, MD, JSON, PDF) makes chats usable as deliverables or version-control inputs
  • Prompt templates with variables and chained prompts remove the copy-paste tax on repeated workflows
  • Data lives locally in the browser rather than on a third-party server, avoiding an extra data-processing hop
  • Lifetime pricing (per platform or all-access) is unusual and cheaper than most SaaS equivalents over a year
  • Small niceties like the Claude artifact vault and Gemini watermark removal address real annoyances
  • Strong all-rounder
  • Voice mode is uncannily good
  • Huge ecosystem & plugins
  • Available in ChatGPT, API, Copilot
Cons
  • Free tier is aggressively limited (2 folders, 2 bookmarks, 5 search results), so it is really a paid product
  • Per-platform pricing means covering all four models costs $199 lifetime or up to ~$40/mo
  • Local-only storage means no sync across machines or browsers without manual export/import
  • Chromium-only; no Firefox, Safari, or mobile support
  • Depends entirely on each vendor's private web DOM, which breaks on UI redesigns until the extension catches up
  • Adds no actual model capability, so it is worthless to anyone who mostly uses the API rather than the web UIs
  • Style can be generic without nudging
  • Hallucinates citations occasionally
  • Context smaller than Claude on long docs
