Speak, and Evolith turns your words into a clean Markdown noteβtranscribed entirely on your iPhone. No account. No servers. Nothing leaves your device. Evolith is a voice notes app for people who want to keep their own words. Tap record, talk, and watch the text appear in real time. Review it, and Evolith saves a tidy Markdown file wherever you keep your notes. WHY EVOLITH β’ On-device transcription. Your voice becomes text using Apple's on-device speech recognition. Audio is never uploaded, and it is never stored after it's transcribed. β’ Your files, your storage. Keep notes on this iPhone, in iCloud Drive, or in a folder you choose. They are ordinary .md files that you fully own. β’ Made for your AI. Evolith writes to a plain folder your desktop AI can read. Point an assistant on your Mac (such as Claude Code) at it and let it work with your real notes. β’ Opens anywhere. Because notes are plain Markdown, they open in any Markdown editor, including an Obsidian vault. β’ No account, no tracking. No sign-in, no analytics, no ads. HOW IT WORKS 1. Tap record and speak. Transcription runs live, on your device. 2. Review and lightly edit. Evolith can add a title and summary for you. 3. Save. Your note becomes a dated Markdown file with clean frontmatter. 4. Find it later in the Journal, searchable by keyword. PERFECT FOR β’ Voice journaling and daily notes β’ Capturing ideas and thoughts on the go β’ Feeding your own AI a folder of your real notes β’ Anyone who wants private, portable, plain-text notes EARLY ACCESS Evolith is free and unlimited while in early access. Paid plans arrive in a later update β and if you install now, unlimited on-device recording and transcription stay free for you, permanently. Optional cloud features that cost money to run will be a separate paid add-on. REQUIREMENTS Evolith needs iOS 26. Live transcription works on every iPhone that runs it. The AI clean-up β tidying the transcript, adding a title and summary, and applying your vocabulary list β uses Apple Intelligence and runs only on iPhone models that support it. On other iPhones, your note is saved as the transcript itself. PRIVACY Evolith has no servers and collects no data. Everything happens on your device.

Turn PDF, Word, Excel, PowerPoint and 10 more formats into clean Markdown β entirely on your iPhone, iPad or Mac. Your documents never leave the device. No server, no account, no upload. WHAT IT CONVERTS β’ PDF, DOC, DOCX, RTF, ODT, EPUB β’ XLS, XLSX, XLSB, ODS, CSV β’ PPT, PPTX, ODP WHAT SURVIVES THE CONVERSION Tables, merged cells, footnotes, headings, bold and italic, nested lists, math formulas as LaTeX, embedded images written out next to the Markdown, and β when you convert a whole folder β the folder structure itself. SCANNED PAGES, HANDLED PROPERLY Pages with no text layer go through on-device OCR. The language is detected automatically, so a Japanese invoice and an English contract in the same batch both come out right. Nothing is sent anywhere to make that happen. HONEST ABOUT QUALITY Every conversion comes with a per-page report: how many pages were read directly, how many needed OCR, how many failed, and why. Most converters hand you a file and hope you do not check. DocNavy tells you what it actually managed to read. BUILT FOR MARKDOWN PEOPLE Made for Obsidian, Logseq, Bear and plain-text vaults. Preview the result, read the raw Markdown side by side, then save the .md file wherever you keep your notes. PRIVACY YOU CAN VERIFY DocNavy makes no network requests at all. You do not have to take our word for it: turn on Settings βΊ Privacy & Security βΊ App Privacy Report, use the app for a few days, and the domain list for DocNavy will stay empty. The App Store privacy label says Data Not Collected because that is literally what happens. FREE AND PRO The free tier is the whole app: all 14 formats, on-device OCR, whole-folder conversion, zip export and the full diagnostics report β every page of every file, however long. One limit applies: 5 documents a day. Pro removes it and changes nothing else: no extra features, no watermark, no upsell. Take it monthly at $2.99 with a 3-day free trial, or pay $29.99 once and keep it. Either way it is a Universal Purchase, so buying on iPhone unlocks iPad and Mac too.
