Smriti

Enterprise Digital Legacy Platform. (Sanskrit: "that which is remembered")

Smriti preserves the expressed self (voice, likeness, words, and stories a person chooses to leave) inside a tamper-evident archive owned by the person and their estate. It never claims to preserve consciousness or continue the person.

Author and sole builder: Abhishek Chougule. Lineage: ACNeuralBrain (origin research) to Smriti (shipped product).

The four engines

Engine	Name	Meaning	Function	State
Likeness	Darpan	Mirror	Photoreal 3D avatar from photos and video	tiering + consent + watermark; reconstruction stub (GPU)
Voice	Pratidhwani	Echo	Voice synthesis	real self-hosted TTS (espeak-ng); cloning next
Mind	Sutra	Thread	Grounded conversational persona	real self-hosted LLM (Ollama), grounded
Integrity	Crystal	Bedrock	Non-forgeable provenance ledger	complete

Every asset and every generated utterance is SHA-256 hashed into a per-subject hash chain, signed with a per-subject Ed25519 key, rolled into daily Merkle transparency anchors, and verifiable by anyone. No runtime dependency on third-party AI APIs: all models are self-hosted and pluggable.

Surfaces (React SPA)

• / landing
• /studio guided Life Interview capture (300 prompts) and time-released messages
• /build in-app consent, voice enrollment/synthesis, avatar build, archive rights
• /sanctum grounded conversation with V/G/I provenance badges, chapter browse, replay
• /verify public integrity check for archives, voice clips, and avatar builds
• /review abuse-review queue (admin)
• /pricing, /privacy, /terms

Trust, consent, compliance

• In-app consent (living: identity + recorded statement; posthumous: estate authority + family consensus), sealed into Crystal.
• Data-subject rights: open-format export (portability) and revocation (erasure with a cryptographic tombstone).
• Watermarking of all synthetic media; public verification.
• Abuse-review queue with human sign-off; family availability windows.
• Security response headers; ISO 27001 / 42001 / DPDP / GDPR control map in docs/COMPLIANCE.md. Status matrix in docs/IMPLEMENTATION_STATUS.md.

Installation

Frappe v16 app. Node 24 or newer is required to build the frontend.

bench get-app https://github.com/Abhishek-Chougule/smriti --branch version-16
bench --site <site> install-app smriti
bench --site <site> migrate

Optional self-hosted models

• Sutra LLM: install Ollama and pull a model (default llama3.2): ollama pull llama3.2. Configure with SMRITI_LLM_MODEL / OLLAMA_HOST. Falls back to extractive grounding if unavailable.
• Pratidhwani voice: sudo apt-get install -y espeak-ng for real speech. Falls back to a labeled placeholder otherwise.

Development

# Crystal unit tests (no site required)
env/bin/python apps/smriti/smriti/crystal/test_crystal.py

# End-to-end smoke tests
printf "from smriti.smoke_phase0 import run\nrun()\n"    | bench --site <site> console
printf "from smriti.smoke_sutra import run\nrun()\n"     | bench --site <site> console
printf "from smriti.smoke_pratidhwani import run\nrun()\n" | bench --site <site> console
printf "from smriti.smoke_darpan import run\nrun()\n"    | bench --site <site> console
printf "from smriti.smoke_family import run\nrun()\n"    | bench --site <site> console

# Frontend
cd apps/smriti/frontend && npm install && npm run build

The frontend build regenerates the served shell (smriti/www/app.html and index.html). Routes are wired in hooks.py via website_route_rules.

Deployment

Do not run production on the dev server. See docs/DEPLOYMENT.md for the supervised stack (Gunicorn, socketio, RQ workers), TLS + security headers, model hosting, scheduler, and backups.

Documentation

• docs/DEPLOYMENT.md production checklist
• docs/COMPLIANCE.md ISO 27001 / 42001 / DPDP / GDPR control map
• docs/IMPLEMENTATION_STATUS.md feature status vs the plan
