# Sider AI: Multi-Model Browser Sidebar

> Sider AI's browser extension has quietly grown to 2 million users by solving a specific friction point: you're reading an article or drafting an email, and you want AI's help, but switching apps to ChatGPT or Claude interrupts the flow. Sider puts GPT, Claude, and Gemini in a sidebar that stays always-on, so you can ask questions without leaving the page or tab. It's the productivity version of having a reference book on your desk. The tool includes templates for common workflows: summarize, translate, rewrite, explain. Those are genuinely useful for people doing writing and research, which is probably why the user base has stuck around. The sidebar also lets you see which model you're using and switch between them, so you can compare responses or use different models for different tasks. It's not sophisticated, but it's practical. For users, it's a $5-10/month subscription if you want all three models. That's low-cost enough to justify for heavy writers or researchers. The bigger play for Sider is probably platform lock-in: once you have Claude accessible in your sidebar, you're more likely to use it, which shifts the default from whoever you were using before. It's working so far, which is why competitors have launched similar products. The space is crowded now, but first-mover advantage (and 2M users) is real.
