Common questions

Sending a file or pasting on the web costs zero tokens — no matter how big the document is. The file is read on your machine (or taken from the web) and uploaded straight to Sendle; the AI model never sees its contents, so size doesn’t matter. The only thing that uses tokens is asking Claude to collect a passage during a chat — that snippet goes through the conversation like anything else you say — and even then it’s just that snippet, not the finished book. Turning a collected book into an EPUB and sending it adds nothing.

Yes — 7 books a month, forever, no card required. Collecting and assembling in Claude Code is always free; only delivery to your reader counts. Send more than 7 a month and Plus ($4/month) removes the limit.

Sendle uses whichever account you’re signed in as when you authorize the plugin. To switch: in Claude Code run /mcp, choose sendle, and pick Re-authenticate — a browser opens, so sign in as the account you want. (Use Re-authenticate, not Reconnect — Reconnect just reuses your current login.) A tell-tale sign you’re on the wrong account: a send says your Kindle address isn’t set even though you’ve added it.

The small page after your content — traditionally, the note at the end of a book about how it was made. Ours currently says “Sent by sendle.app”. It never touches your content, it’s clearly separated, and it shows up honestly in the book’s contents page. Books on the Free plan include it; Plus members can turn it off in Account.

Markdown (.md), HTML (.html), or plain text. Point the plugin at a local file, or paste straight into the web archiver. Sendle renders it into a clean, readable EPUB — proper headings, lists, links, and code — and you don’t need to format anything specially: plain prose just works. Pick a format manually, or let auto-detect decide.

Anything Sendle delivers to your reader: an assembled book from Claude Code, a passage you paste on the web, or a local file you send — each is one book against your monthly count. Collecting and assembling, without sending, never counts.

Two paths. In Claude Code, ask in plain words (or use /sendle) to collect passages and send a book — or send an existing local file directly. On the web, paste a passage into the archiver and hit send.

Mostly. Collecting passages from a chat, assembling a book, and sending it to your reader all run over Sendle’s remote connector, so they work in Cowork the same as in Claude Code. The one exception is sending a local file directly (/sendle:kindle <file>) — it reads the file from your machine, and Cowork’s cloud sandbox can’t reach your local files, so that path needs Claude Code. Pasting on the web works anywhere.

A report generator bundled with the Claude Code plugin. Ask for a write-up — “turn this into a report” or /sendle:single-html — and Claude produces one polished, self-contained HTML file: fixed table of contents, callout boxes, tables, readable offline. It doubles as Sendle input: say “send it to my Kindle” and the same file is re-typeset into a clean EPUB for e-ink. The HTML file stays yours either way.

Almost always the sender isn’t allow-listed. Add Sendle’s sender address to your Amazon Approved Personal Document E-mail List (Manage Content & Devices → Preferences → Personal Document Settings). Your Account page shows the exact address to add. Amazon also emails you when it rejects an unapproved sender.

Yes. Sendle delivers a standard EPUB by email, so any reader that accepts email works — or just your own inbox. “Kindle” is simply the common case.

We store the books you collect so you can manage and re-send them, and you can delete any of them anytime. One-shot sends (paste / file) aren’t stored — only a delivery record (title, timestamp) for your send history. We don’t sell your data — see the Privacy Policy.
