Working with an agent?
Give it the evidence, with the limits.
Use compact audit and comparison reports without putting the whole saved crawl into your prompt. Hosted MCP and HTTP audit helpers are free; local saved-page tools can search the captures you choose.
Other utilities
Keep the tools you already use.
The wider catalog remains available: supplied-HTML text, links and changes, Wikipedia reading with attribution, and deterministic data utilities.

Which check are you repeating?
If you manually recheck something after site edits, tell us about that check. We can help scope a small permitted baseline. No credentials or private client records needed.
Free access, with clear limits
All available hosted tools are free during validation. Existing input, output and source-access limits apply. Full tools and the combined report share capacity limits that count attempts, including failed executions and marked checks; they are not per-user allowances. No account, API key, wallet or funding is needed. Existing credit balances are preserved. Live Reddit remains unavailable until configured. Paid billing will not resume automatically.
Hosted full executions share 1,000 attempts per UTC day and 60 per minute. Local browser audits and comparisons do not consume that hosted allowance. Bounded previews retain their own limits. Results can omit content; inspect source attribution, missing values and truncation. Byte reduction is not measured model-token or dollar savings.
Try a real task, then tell agentutilities@proton.me whether it helped. Omit credentials and private records. Feedback is optional.
