High-quality on-device transcription. Easily convert speech to text from meetings, lectures, and more. The transcription is powered by OpenAI's Whisper running locally on your device. Nothing leaves your device. You can export the transcription as subtitles too. It has a word-replacement feature to let you automatically fix common mistakes. Aiko favors accuracy over speed. It does not do live transcription while recording. It does not currently have speaker detection. Try the trial first. See website. Note: Sharing from Voice Memos on iOS 26 does not work because of a iOS 26 bug outside of my control. Supports audio in 100 different languages: Afrikaans, Albanian, Amharic, Arabic, Armenian, Assamese, Azerbaijani, Bangla, Bashkir, Basque, Belarusian, Bosnian, Breton, Bulgarian, Burmese, Catalan, Chinese, Croatian, Czech, Danish, Dutch, English, Estonian, Faroese, Finnish, French, Galician, Georgian, German, Greek, Gujarati, Haitian Creole, Hausa, Hawaiian, Hebrew, Hindi, Hungarian, Icelandic, Indonesian, Italian, Japanese, Javanese, Kannada, Kazakh, Khmer, Korean, Lao, Latin, Latvian, Lingala, Lithuanian, Luxembourgish, Macedonian, Malagasy, Malay, Malayalam, Maltese, Marathi, Mongolian, Māori, Nepali, Norwegian, Norwegian Nynorsk, Occitan, Pashto, Persian, Polish, Portuguese, Punjabi, Romanian, Russian, Sanskrit, Serbian, Shona, Sindhi, Sinhala, Slovak, Slovenian, Somali, Spanish, Swahili, Swedish, Tagalog, Tajik, Tamil, Tatar, Telugu, Thai, Tibetan, Turkish, Turkmen, Ukrainian, Urdu, Uzbek, Vietnamese, Welsh, Yiddish, Yoruba The app was made possible thanks to Whisper by OpenAI and whisper.cpp by Georgi Gerganov. ■ FAQ ‣ Can I edit the text in the app? I don't plan to support any editing. Export the transcription and edit it in a proper text editor. ‣ Why is the app so large? The app delivers the highest quality transcription on the market for 100 different languages. Rather than asking why it's so large, the real question is how is it so small. ‣ Why is the transcription so slow? The app favors accuracy over speed. However, performance is expected to improve in the coming months. ‣ Why must I keep the iOS app open while it transcribes? iOS apps are fundamentally restricted from operating in the background for extended periods. ‣ Can I delete some of the languages to save space? This is unfortunately not possible. The model has all the languages stored together in a way that makes it impossible to remove just some languages. More FAQs on the website. ■ Technical details The app uses the Whisper medium or small model on iOS depending on available memory and the large v3 model on macOS. ■ Privacy The transcription is done locally on your device. Nothing leaves your device. ■ Support You can contact me through the feedback button in the app.

Ideas never make an appointment. 1dea catches them in a second, files them without effort, and hands them back just when you had forgotten them. Made for people who write, teach, research or simply think: aphorisms, quotes, talk outlines, hypotheses, reading notes, projects. CAPTURE • From the app, from the Share button of any other app, or with Siri and Shortcuts ("Add an idea"). • Markdown formatting: headings, bold, italic, highlight, lists, quotes, code, links. • Formatting bar above the keyboard: code block, equation, highlight, bold, web link and backtick in one tap. • Code coloured by language: Python, Swift, SQL… more than 190 languages in all. • Automatic references: a DOI pasted into a note becomes a numbered call [1], and the full reference, in Nature style, is added at the end of the note. • LaTeX equations, on their own line or in the middle of a sentence. • The place where the idea came to you, added automatically if you wish. GET INSPIRED • A library of 22,539 ideas, in English and French: history, science, nature, film, music… to browse by category, by words or at random. • Take an idea: it opens in a new note, for you to rewrite in your own words and file in your own categories, with its source link. • Related ideas: those sharing the most words with the one on screen. FIND • Search by words, or by meaning: 1dea finds related ideas even when they share no word. • Coloured categories, tags and one-to-three-star ratings to filter in one tap. • Related ideas and links between notes to weave your thinking together. • A world map of your notes. • Ideas graph: a map of your notes and their links, in Tools. REREAD • Home Screen widget: a random idea, from the categories you choose, refreshed anywhere from every 15 minutes to once a day. • "Random idea" in Siri and Shortcuts as well. • Project note: gather several ideas into one working draft. MEASURE • Statistics by month, year, category and rating. • Vocabulary tools: how many words you have written, how many are still ahead of you (Chao2 estimator), and how varied your vocabulary is (Shannon entropy). SHARE • Copy or share an idea as a quote, with your signature. • JSON export and import of your whole library. YOUR NOTES STAY YOURS • No account to create: sync goes through your own iCloud, across iPhone, iPad and Apple silicon Mac. • Search by meaning and statistics are computed on the device. • The idea library is built into the app and works offline. For a reference, only the DOI is sent to doi.org to fetch its record. • Lock with Face ID, Touch ID or passcode. Free, no ads, no in-app purchases. In English and French.

Verdict

The call

Aiko's advantage is chart position (#24 vs unranked) and device support (4 vs 2). On ads and in-app purchases there is nothing between them.
