Logosphere
The only dictionary you’ll need
For writers, poets, philosophers, and all lovers of the word.
Every definition, synonym and origin in one search — and a memory for every word you look up.
01The dictionary
One search.
The whole word.
Logosphere asks several dictionaries at once and folds their answers into a single, clear entry. No tabs, no hopping between sites, no half-answers.
- DefinitionsEvery sense, nested the way meaning actually branches.
- Synonyms & antonymsAttached to the sense they belong to, not just the word.
- EtymologyWhere the word came from, and what it meant on the way.
- PronunciationIPA and audio, so you can say it with confidence.
- ExamplesThe word at work in real sentences.
Every line is credited to the source it came from.

adjective · Too great or extreme to be expressed or described in words.
Type the word.
02Learning
Every word you find,
you keep.
There is no save button, because you will never need one. Each word you look up joins your vocabulary and comes back for review on a spaced-repetition schedule — just before you would have forgotten it.
Recognising a word and being able to use it are different skills. So once a word has stuck, Logosphere turns it around: you read the definition, and you write the word.
- Recall
- New words: remember the meaning, then grade yourself.
- Produce
- From a streak of two: type the word from its definition.
03Together
Words travel in good company.
A social layer built for one purpose: to help words stick. No feed, no likes, nothing to scroll. Just the people whose vocabulary sharpens yours.
Find your kindred readers
Each night, Logosphere compares vocabularies — rare words count for more than common ones — and shows you the people who collect words the way you do.

From your circle
The words your people know and you haven’t met yet, most widely held first. One tap looks it up, and it’s yours.
“We sat on the steps in the apricity of a January noon, coats open.”
Notes on words
Use a word in a sentence after a review and the people who follow you will find it on that word. When a friend is struggling with one you’ve mastered, Logosphere invites you to write them an example.

A league you can’t cheat
You’re ranked against readers with a vocabulary your size, by words truly held — reviewed three times and remembered weeks out. Racing through lookups won’t move you an inch.
04The path of a word
From stranger to second nature.
01
Look it up
Search any word and get everything worth knowing about it, from every source at once.
02
It’s kept
Every word that returns an entry joins your vocabulary. Automatically, every time.
03
It returns
Reviews arrive on a schedule tuned to your memory, right before the word slips away.
04
It’s yours
Write it from its definition. Use it in a sentence. Now you don’t just know it — you own it.
lo·go·sphere
/ˈlɒɡ.əʊ.sfɪə/ · noun
- 1The world of words: every one you have ever met, and every one still waiting for you.
- 2A dictionary that remembers what you look up — and makes sure you do too.“She kept a notebook for years, until she found Logosphere.”

05Principles
Quiet by design.
A place for words, not for noise. Built with the restraint of a good book.
Your progress is private
Schedules, streaks and review history are yours alone. Other people only ever see which words you’ve saved.
Every source, credited
Definitions come from open dictionaries like Wiktionary, and each one is attributed to where it came from.
Curious, not careless
Look up any word you like, crude ones included. Slurs are filtered, and every note can be reported or its author blocked.
