What our research says

Flot AI

Useful if your day happens in native apps — Outlook, Word, a code editor — where browser-only assistants simply cannot reach. Mostly redundant if you already work in a browser all day.

Pros

  • Reaches native desktop applications, not only web pages
  • One account covers Windows, macOS, iOS, Android and a browser extension
  • Saved-knowledge store carries context between sessions instead of restarting each chat

Cons

  • Pricing and legal pages render only through scripts, so plans and terms are hard to read without a full browser
  • The free tier carries only 3 credits and no GPT-4 access, so a real test means paying or relying on the 14-day money-back guarantee
  • Reviewers report the desktop client slowing machines and lagging behind going direct to ChatGPT

Sider

Sider puts a chat panel on top of whatever page you're on, so you can ask about an article or PDF without copying it into a separate tab. The catch is that heavier use beyond the free daily cap needs a paid tier, and pricing quoted across review sites is inconsistent, so the entry price is worth confirming before committing.

Pros

  • Works as a sidebar on any web page rather than a separate chat tab
  • Routes one prompt to several models (GPT, Claude, Gemini, DeepSeek, Grok)
  • Ships native apps for iOS, Android, Windows, and Mac plus browser extensions
  • Can chat with PDFs and YouTube videos, not just plain text

Cons

  • Free tier is capped at a small number of daily uses
  • Independent pricing write-ups disagree on exact plan costs depending on where you check
  • No public API for developers
