Your answers,
with the signal off.
You work through a question bank with an assistant at midnight. Next morning the campus wifi gives up and none of it is there. Losto takes the share link and keeps the whole conversation on your phone - every answer, table, formula and diagram - so it opens in airplane mode, in a basement lab, or on a train.
No account. No server holding your notes. Free.
Keeps chats from
What it does
Three things, properly.
For students and self-learners who study with ChatGPT, Claude, Gemini and similar assistants, and need those answers again when there is no connection.
It reads with nothing connected
Everything sits in your own browser on your own device - the words, the code blocks, the tables, the LaTeX, and the pictures as real files rather than links that expire within hours. Airplane mode, a basement lab, a train through a tunnel: it does not notice.
One answer becomes a checklist
Paste forty questions in one go and the reply comes back as a single message. Losto reads the numbering inside it and gives you forty rows to tick off as you study - grouped by module, each one jumping straight to its own answer.
It hands a chat to the phone beside you
One of you saves it, the rest get a copy - by AirDrop, Quick Share, or a code on the screen that the other phone's camera reads. No account, no upload, no internet at any point. Both screens show the same seven digits, so you know it arrived whole.
Features
And everything around them.
Save anything in a few taps
- Paste a ChatGPT share link and the full conversation is saved: text, code, tables, maths and images.
- Save any blog post, documentation page or article the same way, with author and date kept.
- Drop in the export file from ChatGPT or Claude and your whole history lands at once.
- For assistants whose links cannot be read, paste the text or ask the assistant to hand it over as JSON.
- On Android, share a link straight into Losto from another app.
Read it properly, offline
- Installs to the home screen and opens every page with no connection.
- Answers look the way they were written: highlighted code with line numbers, formulas, sortable tables, callouts and footnotes.
- Mermaid diagrams are drawn, not shown as code, and open full screen to zoom and pan.
- Pictures are stored on the device as real files, so they do not vanish when the original link expires.
- Text size, three typefaces, light and dark themes, and resume where you stopped.
Built for revision
- One long answer becomes a checklist: paste forty questions, get forty rows to tick off, each jumping to its answer.
- Flip any chat into question-and-answer cards and quiz yourself.
- Organise by subject and tags, favourite the important ones, and search the full text of everything saved.
Share with the person next to you
- Hand a saved chat to a friend's phone by AirDrop, Quick Share or an on-screen QR code - no internet at any point.
- Both screens show the same seven-digit code, so you know it arrived whole.
Take it with you
- Export any chat as Markdown, any table as CSV, any diagram as SVG or PNG.
- Back up the whole library to one file and restore it anywhere.
Private by design
- Everything lives in your browser's storage on your own device.
- No sign-up, no analytics, no tracking, nothing used to train anything.
- Delete a chat and it is gone; uninstall and everything goes with it.
Three taps from a link to a library.
Bring it across
Hit Share in ChatGPT and paste the link. Or paste the text. Or drop in the export file your provider gives you, and a whole history lands at once.
It is taken apart properly
Questions and answers, code with its language, tables, maths, diagrams, and every picture copied onto the device before its link expires.
Read it anywhere
Search the full text, tick questions off as you study them, or flip the whole thing into cards and quiz yourself.
What it reads
Including what it cannot.
Losto reads one link at a time, only when you paste it, and only where the site's own robots.txt allows. Plenty of chats are assembled inside your browser and are not in the page at all. When a link cannot be read, Losto says so and walks you through copying it across, which takes a few seconds. Every saved item keeps its source and original link attached.
| Source | What you get |
|---|---|
| ChatGPT share links | Full conversation, code, tables, maths, images |
| Blogs, docs, Medium | Article text, code blocks, images, author and date |
| Your own export file | The file ChatGPT or Claude gives you - a whole history at once, read on the device |
| Pasted text | Anything you copy yourself, split back into questions and answers |
| Claude, Perplexity and the rest | Tried first. Most build the chat in your browser, so Losto shows you how to paste it across |
| ChatGPT images | OpenAI does not publish these in share links - add the file yourself in one tap |
| Logins, paywalls, bot checks | Never. Losto obeys robots.txt and bypasses no access control, ever |
There is no server holding your notes.
The only request Losto makes on your behalf is fetching a link you paste, and the result goes straight to your device. Delete a chat and it is gone. Uninstall and everything goes with it. That is the whole design, not a setting you have to find.
