Monica vs Signal Extractor: unlimited free summaries, no subscription
Monica is an all-in-one AI assistant with a YouTube summarizer inside it. New accounts get two free summaries, then it's a subscription.
The short answer
Monica is a lot of tool: multi-model chat, Deep Research, image generation, PDF chat, slide building, a browser agent, and a YouTube summarizer among them. If you want one subscription to replace three, it's a reasonable bet at $9.90 a month. As a YouTube summarizer specifically, the maths is hard to defend. Monica's own FAQ puts new accounts at two free summary quotas — not two a day, two — and after that summarizing videos is a paid feature. You also install an extension and create an account to get there, and the heavier features run on a separate advanced-credit pool the free plan doesn't get any of. Signal Extractor summarizes videos free, with no account, no extension and no cap. Paste a link and read a one-line verdict plus five to eight timestamped takeaways in about ten seconds, every timestamp clicking straight into the video to check a claim. It handles videos with no captions by falling back to the audio, which caption-scraping extensions can't do at all. Then ask follow-up questions with the transcript in context, push it to Notion, share it, or follow a channel and get every new upload summarized in your inbox — all still free.

Which should you use?
Use Signal Extractor if
You mainly want YouTube videos summarized properly, and you'd rather not pay a monthly fee or spend your free quota deciding whether to.
Use Monica if
You want one subscription covering chat, research, images, PDFs and slides, and video summaries are a small part of a much wider workload.
Monica questions
Is Monica's YouTube summarizer free?
Barely. Monica's own FAQ says the feature is free with two summary quotas for new users, and more quotas come with a paid plan. That's two videos total, not two a day. Signal Extractor has no cap and no paid plan.
How much does Monica cost?
Pro is $9.90 a month, Max $24.90 and Ultra $99.90, as of mid-2026. The heavier features draw on a separate advanced-credit pool, and the free plan gets none of those credits — so the credit ceiling rather than the headline price is usually what decides your tier.
What is the best free alternative to Monica for YouTube summaries?
Signal Extractor, if summarizing videos is what you actually want. It's free with no account, no extension and no daily cap, and you get a one-line verdict with timestamped takeaways plus a chat for follow-up questions.
Do I need to install an extension?
Not here. Paste a YouTube link into the site and the summary starts streaming. There's a Chrome extension if you want one-click summaries while browsing, but nothing needs installing. Monica is built around its extension and account.
Can either one summarize a video with no captions?
Signal Extractor can — it falls back to processing the audio. Extension-based summarizers that read the caption track generally can't do anything with a video that has captions disabled.
Is Monica worth paying for?
If you'd otherwise pay for two or three separate AI subscriptions, consolidating onto Monica Pro usually costs less than any one of them, and that's a fair argument. If video summaries are the main thing you want, you're paying a monthly fee for something you can have here for nothing.
What does Monica do better?
It's much broader. Deep Research, image generation, PDF chat, slide creation, a browser agent, translation and writing help, with a choice of frontier models behind them. This tool does one job, and if you need the other nine, Monica is the better buy.
Which is better for long podcasts?
Signal Extractor handles any length at no cost, so a three-hour interview is the same as a five-minute clip: free. Monica caps video length on its free tier and lifts the ceiling on paid plans.
