Keepr
WhatsApp-native memory · 2026You save links, notes and screenshots in a dozen places and never find them again. Keepr is one WhatsApp number: send it anything to save, then ask for it back in plain words. Text it, forward it, or just talk: voice notes become searchable text.

# decisions
Rules, not a model, for routingA classifier cost a model call on every message. Rules are free, and the bot keeps working when credits run out.
Extract the answer, don't generate itRecall pulls the exact password, link or date out of the saved message and quotes it. No made-up answers.
Claim before processingWhatsApp retries webhooks. Claiming each message ID first means a retry never costs a second reply.
Pre-filter by userVector search only looks inside one user's memories, so results stay private and fast.
