TextLighter

TextLighter highlights words and phrases you save, on the pages you read. Your lists stay on your device.

Every word that matters, lit up as you read. TextLighter is a free Chrome extension that highlights the words and phrases you save — in soft, hand-drawn marker strokes — on every web page you visit. No account. No tracking. Nothing leaves your device. Right-click, nothing else. Select a word, right-click, and choose "Highlight this word" or "Add to group". Nothing pops up when you merely select text — the page stays clean until you ask for something. Highlights like a real marker. Every match gets a soft, hand-drawn stroke — one slow wave across the line, feathered edges, ends that taper off. It looks like a person highlighted the page, not a machine. Hover for the meaning. Write a short description when you save a word — a definition, a translation, a note to yourself — and it appears as a plain text tooltip when you hover the highlight. Nothing else. No cards, no buttons. Groups with their own colours. Keep words in groups — Reading, Japanese, Quotes, whatever you like. Pick one of eight colours, or any custom colour. Every word in a group follows that group's colour. Rename groups, drag them into order, mute one for a while, or flag a word as urgent. Standalone highlights, page by page. Some passages matter on one page only. Highlight a phrase as a standalone and it lights up every occurrence of that phrase on that page — and stays on this device only, never synced. Your list, in your hands. Export everything — words, groups, colours, descriptions, standalone highlights — as one CSV file, in the same format Import reads. Import CSV, Excel or older JSON backups, review what will change first, and re-importing the same file never duplicates anything. Syncs through your Chrome. Signed into Chrome? Your groups and words travel with your own Chrome sync to your other devices — per item, newest wins. Too big to sync, and it simply stays on this device with a plain note. Pause it, undo it, find it. Pause all highlighting, or pause it on just this site. Jump between matches with Previous and Next, filter by group, and undo a removal for two minutes if you change your mind. Light, dark, or your system theme. Free. No account, no ads. Works offline.
