Comment on the exact line
Pin questions, suggestions and highlights to specific lines or ranges, with threaded replies — all in a layer over your code that never touches the source.
One link — the code and the why, together
A plain paste loses the one thing that mattered: the context
Pasting code into Slack, Discord or a throwaway pastebin strips away the why. ShareCode keeps it attached — pin notes to exact lines, thread a real discussion and bundle every file in one link. Share without an account, or sign in to keep history.
- No account needed — you keep edit & delete tokens
- Set an expiry, a view cap or a password
- Secret scanner flags keys before you share
Everything a paste tool is missing
Built for explaining real problems across real codebases.
One link, every file
Drop in the controller, the test and the config — ShareCode detects the language from each filename across 29 languages and links related spots across files.
Version history with diffs
Every update is saved as a new version, and you can compare any two side by side with line-level diffs showing exactly what changed.
Secrets caught before you share
A built-in scanner flags AWS, GitHub, Slack and Stripe keys, JWTs, private keys and connection strings — as you type, and again on the server as the authority.
Lock it behind a password
Set an optional password on any share; viewers must unlock before a single line renders, and the gate holds on the page, raw text, ZIP and preview card alike.
Focus mode for walkthroughs
Toggle comments and highlights, or show only the annotated lines, to turn a share into a clean, guided tour through the parts that matter.
Hand the whole thing to an AI
Copy for AI exports every file plus all annotations and threads as one clean, paste-ready block — or grab Markdown, a ZIP, or the raw text endpoint.
How it works
From code to a shareable, annotated link in three steps.
- 1
Paste or pick files
Drop in one file or several — or just the parts that matter.
- 2
Attach the context
Select code and add comments, highlights and notes as a separate layer over the source.
- 3
Share one link
Set visibility, expiry or a password, then send a single link anyone can open.
More than a paste
The details that make code actually understandable.
Comment right in the code
Annotations render inline next to the lines they describe, with threaded replies — and your source stays untouched.
Versions, history & diffs
Push a new revision, keep older links working, and compare any two versions side by side with line-level diffs.
One click for AI
Export the whole context — files, notes, questions — as one structured block ready to paste into an AI assistant.
Made for real work
However you share code, ShareCode fits.
Code review
Walk a reviewer through a change with inline comments and suggestions on the exact lines.
Teaching & docs
Explain a snippet step by step with highlights, notes and focus mode.
Bug reports
Attach logs, screenshots and the exact lines that break across every file involved.
AI prompts
Package multi-file context and your questions cleanly into one prompt for any AI assistant.
Frequently asked questions
Everything you need to know before you start.
Do I need an account?
No. You can create and share code anonymously and keep your edit and delete tokens. An account adds a dashboard, longer expiry and higher limits.
How long do links last?
You choose — from 10 minutes to a year, or never on paid plans. You can also cap a link to a number of views, including one-time links that burn after the first read.
Is my code private?
Unlisted links are only reachable by people with the URL, private shares require signing in, and you can lock any share behind a password — enforced everywhere the code is served.
What about secrets in my code?
A built-in scanner flags likely API keys, tokens and passwords as you type and again on the server, so you can redact them before anything leaves.
Can others comment?
Yes — enable commenting and recipients can discuss specific lines, with threaded replies and resolvable notes.
Can I delete a share?
Anytime. Deleting a share removes it immediately; expired anonymous shares are cleaned up automatically.
