Draft Slack replies in your own voice, right from the thread.
ForthWrite adds a message shortcut, a compose shortcut, and a /forthwrite command to Slack. Open any of them and get a private draft that sounds like you, built from your own writing history, not a generic AI voice.
Free accounts can connect Slack. Drafting in Slack requires a ForthWrite Standard or Pro plan. New here? Create a free account, then upgrade when you are ready to draft.
AI disclaimer. ForthWrite uses AI (large language models) to generate draft messages. Outputs may be inaccurate or incomplete. Always review a draft before sending.
Open a shortcut
Replying to a message? Open its "More actions" (`...`) menu and choose "Draft with ForthWrite." Starting fresh? Type `/` in any message box and choose "Compose with ForthWrite." Prefer the keyboard? Type `/forthwrite` followed by what you want to say.
Invite ForthWrite to the conversation
For channel context, invite the ForthWrite bot once with `/invite @ForthWrite`. Public channels, private channels, and group DMs each need the bot present so it can read the recent messages you asked it to draft from.
Add context if you want
Replies can optionally tell it what to say (it reads the message and, if there's no formal thread, the recent conversation around it). New messages and /forthwrite work the same way: give it an instruction, or leave it blank and let it read the conversation.
Review your private draft
A draft in your own voice opens in a modal only you can see. Copy it in, edit it, or regenerate. AI drafts can be wrong; always read before you send.
What this app can and can't do
- ForthWrite never posts a message on your behalf. Every draft is delivered privately and you decide whether to send it.
- The app only reads the recent messages in the specific conversation you ask it to draft for (via the ForthWrite bot in that conversation), a single thread, or a bounded window of recent history, never your full workspace history in bulk.
- Drafts are generated using your own writing history so replies sound like you, not a generic AI voice.
