Paid plans start at $8/mo. There's also a free plan.
Bit.ai has a free plan, while paid Pro starts at $8 per user/month and Business at $15 per user/month, both shown as annual-billing equivalents. The pricing page says annual billing saves 25%, but does not publish monthly-billing prices. Free is capped at five members, 50 documents, 5 MB files, and 1 GB storage. Pro raises that to unlimited documents and 500 GB; Business adds trackable documents, unlimited storage, and free guest access. AI words beyond the included allowance cost extra.

03Which plan should you buy?

04Is Bit.ai worth the money?
Bit.ai’s case is consolidation: docs, wikis, collaboration, AI writing, sharing controls, connected search, and embeds sit in one platform. That can make the paid tiers easier to justify if your team needs those functions together, but the pricing page leaves a key comparison unanswered: monthly-billing rates. Pro’s $8 equivalent is not a monthly-pay quote, and AI usage can add $10 per 100K words. We’d treat Free as a constrained evaluation tier and price annual seats plus AI usage before switching.
Bit.ai pricing FAQ
What does Bit.ai do?
Bit.ai is a platform for creating and managing team documents, wikis, notes, and knowledge. Its listed features include real-time editing and commenting, AI writing tools, connected search, and sharing through links, embeds, guest access, password protection, or expiration.
How much does an AI cost?
For Bit.ai, the AI Genius Writing Assistant add-on costs $10 per additional 100K words per month, up to 1 million words per organization. It is available on paid plans. Pro includes 20K AI words plus add-on options; the pricing details do not specify a separate AI price for that included allowance.
What is Wit.AI's pricing?
This pricing information covers Bit.ai, not Wit.ai. Bit.ai lists Free at $0, Pro at $8, and Business at $15 per user/month on annual billing. We don't have sourced Wit.ai pricing here, so we can't quote its plans or rates.
Is the Bit.ai app safe?
We can't verify overall safety from the available pricing details. They mention password protection and expiration for sharing, plus trackable documents on Business, but do not document encryption, certifications, or other security controls. Treat those sharing features as access options, not proof of overall safety.
