Installing on Mac
- Download the Proviso installer package from your access email.
- Run
install.shin Terminal — it copies the manifest automatically. - Open Microsoft Word and go to Insert → Add-ins. Proviso should appear.
manifest.xml to ~/Library/Containers/com.microsoft.Word/Data/Documents/wef/. Create the wef folder if it doesn't exist.- Open Word and go to Word → Preferences → Ribbon & Toolbar.
- Check the box next to Developer.
- Click Save. The Developer tab will appear in the ribbon.
You can also load the add-in via Insert → Add-ins → My Add-ins without the Developer tab.
The wef folder is created by Word automatically — but only after you've opened Word at least once. If it's missing:
- Open Word (just the app, no document needed), then close it.
- Navigate to
~/Library/Containers/com.microsoft.Word/Data/Documents/in Finder. - Create a folder named
wef(lowercase). - Copy
manifest.xmlinto it. - Restart Word.
Installing on Windows
- Download
manifest.xmlfrom your access email. - Open Word and go to Insert → Get Add-ins.
- Click Upload My Add-in at the top.
- Browse to
manifest.xmland click Upload. - Proviso will appear in your ribbon under Home.
Sideloaded add-ins on Windows sometimes need to be re-added after a restart. To make it persistent:
- Ask your IT admin to deploy the manifest via Group Policy or the Microsoft 365 Admin Center.
- Or re-add it via Insert → Get Add-ins → Upload My Add-in each session.
BYOK — Optional API Key
- Open Proviso in Word and click the gear icon in the top-left of the taskpane.
- Under API Key, paste your Anthropic API key (starts with
sk-ant-). - Click Save. Proviso will confirm the key is valid.
Don't have an Anthropic API key? Get one at console.anthropic.com — billing is pay-as-you-go, typically $0.01–0.05 per review.
- Make sure the key starts with
sk-ant-— Proviso uses Anthropic's Claude API. - Check that you haven't included extra spaces before or after the key.
- Verify the key has billing enabled in the Anthropic console.
- If you're on a free tier, you may need to add a payment method to enable API access.
Common Errors
This usually means the local server isn't running. Proviso's Word add-in connects to a local backend on port 3041.
- Open Terminal and run:
pm2 status— check thatclaw-legalshows as "online". - If it's stopped, run:
pm2 start claw-legal - Reload the taskpane in Word (close and reopen the Proviso panel).
- The Proviso backend server needs to be running on
localhost:3041. - Verify with:
curl http://localhost:3041/api/health— should return{"ok":true} - If it times out, restart the server:
pm2 restart claw-legal - Make sure no firewall is blocking local port 3041.
- BYOK users: Confirm your API key is saved and has credits in the Anthropic console.
- Managed users: You may have reached your monthly review limit (150 for Solo, 500 for Team). Check your usage in account settings.
- Make sure there's an open document in Word with readable text — scanned PDFs without OCR won't work.
- Try switching to Express Mode in Review settings — faster and uses less tokens.
- Close the Proviso taskpane completely.
- Go to Insert → Add-ins → My Add-ins and remove Proviso.
- Clear the Word add-in cache: delete all files in the
weffolder. - Re-add the manifest and restart Word.
Plans & Billing
BYOK (Bring Your Own Key): You connect your own Anthropic API key. Proviso pays nothing for the AI — you pay Anthropic directly at ~$0.01–0.05/review. Best if you already have an API key or want the lowest possible cost.
Managed: Proviso handles the AI infrastructure. You pay a flat monthly rate and get a set number of reviews included. No API key needed — works immediately. Best if you want zero setup.
Both tiers get identical features — every playbook, NDA Calibrate, Ask, Draft, and Library.
All Proviso plans are month-to-month — no annual contracts, cancel anytime.
- In the Proviso taskpane, click the gear icon and go to Billing.
- Click Manage Subscription to open the billing portal.
- You can upgrade, downgrade, or cancel from there.
