How CharityIQ compares to the main AI tools for UK charities
CharityIQ is grounded AI for UK charities — it matches grants, drafts applications, handles Charity Commission compliance and measures impact, with every claim cited to its source. Here it's compared honestly, side by side, with the alternatives charities weigh up: FundRobin, Plinth, Undercroft and Charity Excellence's free AI Bunny — what each does best, and who should pick which.
Plinth
Both are good tools — but they’re built for different jobs. Plinth is a broad, all-in-one platform. CharityIQ goes deep on the work that actually brings money in: grant writing, Charity Commission compliance and impact — with AI grounded in your charity’s own data.

FundRobin is a cheap way to match and draft grants. CharityIQ does that too — grounded in your data and cited — and then keeps you compliant and reporting impact all year, so the work doesn’t stop at the bid.

Undercroft builds bespoke, self-hosted AI for charities with the budget for it. CharityIQ gives most of the same grounded, audited AI as a self-serve product from £49/month — live today, no implementation project.

AI Bunny is a free, generic bid writer — genuinely useful for a one-off application. CharityIQ is the grounded platform that actually knows your charity and runs your grants, compliance and impact all year.

It uses your charity’s data, not guesses
Every draft is grounded in your real Charity Commission profile, past applications and local statistics — and cites each figure. No invented numbers, nothing to embarrass you in front of a funder.
Grants, compliance and impact in one place
One tool for the three jobs that win and keep funding — instead of stitching together a free bid writer, a spreadsheet, and a reminder you forgot to set.
Built for UK charities, by someone who runs one
UK funders, UK regulators, UK pricing and SORP 2026 built in — from founder Ivan Siyanko, who runs a UK charity. Not a global tool you have to bend to fit.
An audit trail trustees can trust
Every output is logged with its sources and waits for human sign-off — so trustees, funders and the Charity Commission can see exactly how each answer was reached.
