Why Is Everything Free?
We believe powerful YouTube tools should be accessible to everyone.
Open Access
Learning and content creation tools should be accessible to everyone, regardless of budget. Students, researchers, creators — everyone deserves free access.
Your Own API Key
For AI features, you use your own Gemini API key. Google provides generous free tiers, and we never see or store your key — it stays on your device.
Community Driven
NoteLM.ai is built for the community. Your feedback drives our development. We're focused on making the best free YouTube tools available.
About the Gemini API Free Tier
The YouTube Video Summarizer uses Google's Gemini AI. Here's what you need to know about API costs.
Google Gemini Free Tier Includes
Google provides a generous free tier for the Gemini API — no credit card required:
- 15 requests per minute — More than enough for casual use
- 1 million tokens per minute — Can summarize very long videos
- 1,500 requests per day — Sufficient for most users
Typical usage: Most users summarize 5-20 videos per day, well within the free tier limits. Even power users rarely exceed these generous quotas.
Note: The other 4 tools (Transcript Generator, Comment Extractor, Thumbnail Downloader, Subtitle Downloader) don't require any API key — they work completely offline using YouTube's existing data.
Pricing FAQ
Common questions about NoteLM.ai pricing and costs.
Will NoteLM.ai ever become paid?
All 5 current YouTube AI tools will remain free forever. We may introduce additional premium features or new products in the future, but these 5 core tools — Transcript Generator, Comment Extractor, Thumbnail Downloader, Subtitle Downloader, and Video Summarizer — will always be free.
Which tools require an API key?
Only the YouTube Video Summarizer requires a Gemini API key (free from Google). The other 4 tools — Transcript Generator, Comment Extractor, Thumbnail Downloader, and Subtitle Downloader — work instantly with no API key or setup required.
Do I need to create an account?
No. All NoteLM.ai tools work without any account or sign-up. Just visit the tool page and start using it immediately.
Are there any usage limits?
For the 4 non-AI tools, there are no limits — use them as much as you want. For the Video Summarizer, the only limit is your Gemini API quota, which is very generous on the free tier (1,500 requests/day).
How does NoteLM.ai make money?
Currently, NoteLM.ai is a passion project focused on providing free, high-quality YouTube tools. We may explore optional premium features or sponsorships in the future, but our core tools will remain free.
Is my data safe?
Absolutely. We follow a privacy-first approach. For AI features, your API key is stored locally on your device and sent directly to Google's API — we never see or store it. For non-AI tools, all processing happens in your browser.
