Local Gemma vs. pasting into ChatGPT
Both work. The trade-offs are different enough that one is usually obviously better for a given input. Here's the honest side-by-side.
| This tool (local Gemma 4) | Paste into ChatGPT / Claude | |
|---|---|---|
| Privacy | Runs in your tab; text never hits a server when WebGPU is available | Goes to a third-party server; covered by their training and retention policy |
| Quality on long, dense prose | Solid for ~3-4k words; loses thread on multi-document reasoning | Notably better on long-context synthesis and obscure jargon |
| Cost / friction | Free; first load downloads the model (~1 GB), then cached | Free tier rate-limited; paid plans needed for sustained use |
A reasonable rule of thumb: if the input is internal (meeting notes, email threads, customer transcripts, draft strategy docs) — use this. If it's a public arXiv paper or a 50-page legal filing where you want maximum reasoning quality, paste it into a hosted frontier model. Both formats supported here — Paragraph, Bullet points, TL;DR (1-2 sentences), or Key takeaways — work with any of the three lengths. Output is capped at 768 tokens; for very long source text, summarize in sections and re-summarize the joined summaries.

Frequently Asked Questions
How long can the input text be?
Gemma 4 in the browser handles several thousand words at a time. For very long documents, split them into sections and summarize each.
Is it accurate?
The AI is trained to capture main ideas without inventing facts. As with any AI, we recommend you verify claims before citing them.
Does it work offline?
After the first load, the model is cached in your browser and works offline. No internet needed for subsequent summaries.
Can I summarize PDFs?
Not directly — copy the text from the PDF and paste it in. A dedicated PDF summarizer is on the roadmap.
What formats can I choose?
Paragraph, bullet points, TL;DR (1-2 sentences), or key takeaways.
