How It Works

  • Green upload icon with arrow pointing upward, centered on a white background, with the name 'Hannah' below.

    1. UPLOAD PLANNING DOCUMENTS

    Find these on your local council’s planning portal by entering the planning application number, & upload all relevant documents from the applicant to Objector.

  • Green magnifying glass icon with the name Hannah below it.

    2. CHECK OBJECTION GROUNDS FOR FREE

    Find out if there are valid objection grounds & view their impact ranking of high, medium or low.  If there are no valid grounds, we’ll advise you not to continue, and you won’t pay a penny.

  • A neon green outline of a megaphone with lines indicating sound or speech, against a white background.

    3. GENERATE OBJECTION LETTER & TOOLKIT

    Generate your complete planning toolkit, including an objection letter, lobbying letter/video, & planning committee speech - all with planning policy references.

You can use generic AI to write your objection letter, but it’s a bit like asking Dr Google for a diagnosis - you’ll get an answer, but it probably won’t be the right one.

Why Objector?

AI Built for the Planning System

Unlike generic AI, Objector is purpose-built for the UK planning system, combining multiple AI models with planning-specific expertise.

Specialist— Three specially trained AI models cross-check every result

More accurate — 95% vs 61% identification of key planning issues (based on real officer reports)

Finds what matters — Uncovers the critical issues that can make or break a planning decision, rather than surface-level analysis

Affordable - Analysis you can trust without expensive consultants

The Result - Policy-centred, evidence-based objections that carry real weight in the planning process.

“Objector has been a very useful tool for our community. We used the platform to identify our ‘high impact’ concerns, & now feel empowered  to challenge these issues.”

— The Moylgrove Community, Pembrokeshire

Object to Outline Planning or Full Planning Applications

Facing a large-scale development? This is your first & often strongest chance to stop it before it starts.


Outline applications decide whether a development can go ahead in principle — before most details are fixed.
Don’t let developers push plans through unchecked. Identify what can be challenged, submit clear, policy-focused objections & make your community’s voice impossible to ignore.
