The internet has too many meme generators. It needs better captions.

What we publish

Six caption categories — reaction, birthday, cat, comparison, plus two platform-tuned guides for Instagram and Discord. Each page holds 30–50 short captions, hand-grouped by mood or use case, with a paired template hint. We add 10–20 new captions a week, mostly to the platform pages because culture moves fastest there.

Who writes the captions

Captions are written by a small editorial team that has run meme-driven content for shopify-style brand accounts and meme-aggregator pages since 2021. We don't list individual names because we revise each other's lines aggressively — by the time a caption is on the site, three of us have argued about a comma.

How we test

Every caption gets posted twice in the same week — once on a meme-aggregator account, once on a friend's small personal account — and we track three metrics: save rate, send rate and screenshot rate. Lines that fail to outperform a generic caption in both contexts get cut. The page you're reading is the lines that survived.

• Save rate: measured against a control caption of the same image with a generic line.
• Send rate: tracked via Instagram Insights and Discord forward-tracking when available.
• Screenshot rate: approximated through Instagram's "share to story" counts and Discord copy-link uses.

Our editorial standards

• No AI-generated captions. Every line is written by a human. Models are great at remixing existing memes; they're bad at the specificity that makes a caption feel personal.
• Under twelve words. Captions that need a paragraph to land aren't captions.
• Originality over recycling. If a line was already on a 2020 listicle, we don't publish it.
• HR-aware tagging. Captions that won't survive a workplace screenshot get tagged separately so you can pick safely.
• Source-respecting. Templates we suggest are tagged by their canonical name (Drake, two-buttons, smudge) so you can find them anywhere — including in MemeFast's template library.

Relationship with MemeFast

CaptionLab is the editorial sister site of MemeFast — a fast meme generator with 2,000+ templates, AI text-to-meme generation, and offline mobile editing. We supply the words, MemeFast supplies the image. We link to MemeFast where it makes sense (because it's the fastest way to turn a caption into a finished meme), but our content is independent — none of the captions are AI-generated by MemeFast or any other tool.

How to use captions from this site

Every caption is free to copy and reuse on Instagram, TikTok, Discord, X, Threads, Reddit and any other public-facing platform. You don't need to credit CaptionLab, though we appreciate it when people do. If you'd like programmatic access to the library or want to suggest a caption category we should cover, get in touch.
