The Verdict
Heptabase is built for researchers and students, with a focus on whiteboards and card-system. Slite targets remote teams and startups and leads with ai-assistant and doc-editor.
Pricing is close: Slite starts at $8/mo versus $11.99/mo for Heptabase — not a deciding factor on its own.
Slite has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. Heptabase requires a paid subscription from day one.
Bottom line: Heptabase has a slight overall edge — but if ai that actually reads and answers from your docs matters most to you, Slite may still be the right call.
