Information approval and report approval are separate decisions.
04 / Find and check evidence
An answer is more useful when you can check its source.
Use Ask Rangka to find reported project information and inspect supporting evidence. Check the source before relying on an interpretation.
- Retrieve information from the project record.
- Follow supporting evidence back to what was reported.
- Distinguish a reported fact from an unresolved question.
AI query allowances depend on your plan. A source cannot confirm something the team has not reported.

Before your first update
Will it fit the way we work?
Does everyone on site need to learn a new app?
Field contributors report through the connected Telegram project group using messages, voice notes and photos. The project manager uses Rangka to review the prepared information.
How do we get started?
Create your account, verify your email and set up your workspace and project. Connect the project Telegram group, then invite the people who will report from site.
What happens when AI gets something wrong?
The project manager can correct the prepared update before approving it. Original evidence stays connected. Approved information can contribute to a report draft; the final report needs a separate PM approval.
Can we start for free?
Yes. The Free plan includes 1 active project, 1 manager and 3 field contributors, with monthly usage limits. Paid plans provide more capacity. See pricing for current allowances and terms.
Can I check where an update came from?
You can return from a prepared update to its connected source messages and available media. An interpretation is kept distinct from what was reported and from the project manager’s decision.
Does Rangka automatically change the programme?
No. Programme assessment requires suitable programme data, and schedule changes require a separate review decision. An issue reported from site does not automatically establish a delay or entitlement.
