Rules

Your pre-send checks, per platform. Risky messages are stopped at the gate before they leave.

i

Checks run in two tiers: instant local checks fire while you type, while AI and connected-tool checks run once at send time — so deep checks never slow the keyboard down.

Built-in checks

Instant local checks — zero AI cost, zero latency

Connections

The external tools Presend can consult at send time. Connect an MCP server or a plain REST API and your rules can check a message against the systems you already run on.

Voice

Teach Presend how you actually write, so it can score and rewrite in your tone — not ChatGPT's.

New rule

When
Check

The AI evaluates each message against this prompt at send time (~10 tokens per check).

i

Agentic checks run at send time only — never while you type. If a connection is unavailable the check is skipped and your send is not blocked.

No extra check — the trigger conditions above are the rule. If they match, it fires.

Then

Block stops the send until you confirm · Warn flags it · Note is just an FYI.

Add connection

The MCP server endpoint Presend connects to.

This description is shown to the AI — say what the tool is for, so it knows when consulting it is worthwhile.
