Is Easydict really free?

Yes — Easydict is free and open source. The catch is that most of its good translation services require you to apply for your own API keys from providers like Youdao, Baidu or DeepL, and some of those have their own quotas or fees. The app is free; the setup is the price.

What's the difference between translation and in-context explanation?

Translation converts a sentence into another language. In-context explanation tells you what a word or phrase means in the sentence you're reading — which sense applies, what the jargon does in the argument — in the same language. For readers who want to stay in the original text, explanation is the more useful answer.

Can PopGloss replace Easydict entirely?

If your main need is high-volume translation between languages, no — Easydict or a translation-first tool fits better. If your main need is understanding unfamiliar terms while reading (papers, docs, books), PopGloss is built exactly for that.

How much does PopGloss actually cost per month?

There is no monthly cost. $10 buys 1,000 credits that never expire; one explanation costs 1–3 credits depending on length. At 20 lookups a day, a pack lasts roughly one to three months — $3–10 per month of actual use, with no auto-renewal.

Easydict alternative for readers, not tinkerers: zero-config in-context explanations

Easydict is free and open source — if you enjoy configuring API keys. PopGloss is the zero-config alternative: no keys, in-context answers, $10 once.

Key takeaways

Easydict is excellent and free — but its power depends on services you configure yourself, usually with your own API keys
PopGloss is the opposite bet: zero configuration, no keys, no accounts — you pay per explanation instead of with setup time
Different answers, too: Easydict translates; PopGloss explains what the text means in this sentence
Privacy model differs: PopGloss's server stores no text, only a hash and length; with BYO-key tools your text goes to whichever providers you configured
Rule of thumb: tinkerers and heavy translators → Easydict; readers who want it to just work → PopGloss

The short answer

Easydict is a great free, open-source lookup tool — if you're willing to apply for and configure API keys. PopGloss is the alternative for everyone else: download, grant one permission, select text, and get an in-context explanation. No keys, no services to wire up, no account. The trade is $10 for 1,000 never-expiring credits instead of an afternoon of setup.

Where Easydict genuinely wins

Credit where due — this comparison only makes sense if we're honest about Easydict's strengths:

Free and open source. Inspectable code, community-driven, no payment at all.
Translation-first, multi-service. It aggregates many translation engines and OCR, which is powerful for high-volume, cross-language work.
PopClip-style workflows. If you already live in that ecosystem, it slots right in.

If you're a developer or power user who enjoys wiring up services — or you translate more than you read — Easydict is probably the right tool. Seriously.

Where the friction shows up

The cost of Easydict isn't money; it's setup and maintenance:

API key hunting. The good services behind it (Youdao, Baidu, DeepL, OpenAI-compatible endpoints) each require signing up, verifying, and generating keys. Some have their own quotas or fees. Expect an afternoon.
Keys rot. Keys expire, quotas get hit, services change terms. Every few months something needs re-configuring.
It translates; it doesn't explain. For a reader, the commonest question isn't "what's this in Chinese/English" but "what does this word mean in this sentence" — which sense of "significant", what this acronym does in this paper. Translation engines answer a different question.

None of this is a flaw. It's a product aimed at tinkerers. Most readers aren't tinkerers.

What PopGloss does instead

	Easydict	PopGloss
Setup	Apply for API keys, configure services	Download, grant Accessibility, select
Answer type	Translation / dictionary entries	1–3 sentence in-context explanation (what it means here)
Context awareness	No	Reads 100/200/500 chars around the selection automatically
Cost	Free (your setup time; some providers charge)	10 free credits, then $10 = 1,000 credits, never expire
Privacy	Text goes to whichever providers you configured	Server stores no text — only a hash and length; history stays local
Best for	Heavy translation, tinkerers	Reading papers, docs, books without breaking flow

The honest bottom line

Choose Easydict if you're comfortable managing API keys, want free-forever, and mostly need translation across languages.
Choose PopGloss if you want to select a term mid-sentence and get a 2-second, in-context explanation with zero setup — and you'd rather pay $10 once than spend your afternoon configuring services.

They're not really competitors; they're the same category aimed at different people. If you've read this far nodding at "I just want it to work" — that's who PopGloss is for.
