Common questions

Can I use Cognitiv+ or LegalSifter on my phone?

No. Neither tool has a mobile app or mobile-friendly interface. Both require a desktop computer—Cognitiv+ works in a browser, and LegalSifter requires Microsoft Word on Windows or Mac.

Which is better for a solo lawyer or small law firm?

Neither is a good fit. Both are priced for enterprise teams and require significant setup. For a solo lawyer, a simpler tool like ChatGPT with a contract review prompt or a low-cost CLM like PandaDoc would be more practical.

Is Cognitiv+ better than LegalSifter for regulatory compliance?

Yes. Cognitiv+ has dedicated Horizon Scanning for regulatory changes, while LegalSifter is purely focused on contract review and does not track regulations.

Do these tools work with PDFs?

Yes, both accept PDF inputs. Cognitiv+ also handles DOCX, TXT, and HTML. LegalSifter handles DOC, DOCX, PDF, and plain text.

How long does it take to get started with LegalSifter?

Plan for at least a few days to a week. You need to sign up, upload or create playbooks, install the Word add-in, and calibrate the AI sensitivity. It's not a 5-minute setup.

Is there a free trial for either tool?

Neither tool advertises a free trial. Both require contacting sales, which suggests a high-touch, paid onboarding process.

Both Cognitiv+ and LegalSifter are powerful but expensive enterprise legal tools—neither is right for everyday users or small firms.

If you're a non-technical person or small business owner, skip both of these tools—they're built for big legal teams with big budgets. For contract review, try a simpler AI like ChatGPT with careful prompts, or a low-cost contract management tool. If you're part of a large legal department, LegalSifter is the more practical day-to-day choice for contract work, while Cognitiv+ is better if regulatory compliance is your main headache.
